There are those of us out here who are very healthy and never go to the doctor so we never get asked any of these questions…
Fact checkers like this guy are dubious to the extreme
Facts can be all correct but the information presented can completely misrepresent a topic
That's what the sophisticated mainstream media system does
You pick out certain facts to promote your narrative and leave out key facts that go against your narrative
Anyone tells you they are a fact checker that is usually someone working for vested interests
Gram lived to be 104. Great cook too. She grew most of here food and preserved it herself by canning. Pork was grown at home and cured with salt, sugar and pepper. She made her own sausage. Not much of the pig was wasted except the squeal. She milked her own cows and made her own butter. I'll follow her advice.
Sounds like something they'd say in Japan.
And Japan has a lot of very healthy seniors.
I’m a medical student and I absolutely LOVE these videos! Dr. Prasad is absolutely riveting! So engaging and articulate! Working on typical research projects involving topics like pharmaceuticals is so frustrating to me, I wish I could do research with him! I’m really sick of the propaganda and lies Big Pharma, the AMA, and other medical governing bodies push on us. Really ruins the fun of learning medicine for me. But Dr. Prasad’s work and explanations are something else!!
I'm so happy that there is someone like you in the system. Use your power for good!
I'm a 57 year old grandmother and thought if he were my instructor I could get through med school.🙂
Yes we are "Drowning In An OCEAN of PROPAGANDA"...! Hang in there - after you get your degrees and credentials you can act upon your own FACT BASED desire to help others.

As a recently retired dietitian, I was so happy to see you take on this topic! I spent most of my career swatting these gnats of media hype that patients shared with me. I have seen various nutrition fads come and go (low fat, low carb, etc), I watched renal nutrition (my area) change from forbidding patients to eat vegetarian diets to now promoting them. I do think my grandmother knew best! She lived to 100; my grandfather to 97, and they ate 3 meals a day, starting with bacon, eggs and toast with butter and ending with a dinner including meat, 2-3 vegetables and a small amount of potato or rice. Thank you for continuing to share your logical thinking process with us--I would have gotten even more out of my grad school statistics class if I'd been able to listen to you back then. I've learned so much from you!
Lynn - as a I-left-the-RD-profession years ago and not just 'cuz raising family, I clicked on video real fast to save to watch later as well as checking transcript notes. Can't wait to watch when got time to enjoy the just desserts and digest what video serves up! Yes to your comments!
Swatting these gnats. I love it! 😂
Fellow RD here. More than 50% of my time is spent explaining to patients why the nutrition information they read or see on TV isn't reliable or at the least applicable to them.
The Academy of Nutrition and Dietetics, was founded by members of the Seventh-day Adventist Church as the American Dietetic Association in 1917. These are the people who register dietitians, and Adventists are vegetarians because one of their founders, Ellen G. White had "visions" that meat causes cancer, and believe meat consumption caused sexual desire among young people. One of her disciples was John Harvey Kellogg, who ran the Battle Creek Sanitarium and obsessed with stopping masturbation among his clients. The Adventists also created Loma Linda University, and they are the reason we have such a plant-based push in America and the world these days.
@Lynn Munson love your comment! I gave up trying to follow dietary recommendations for different health diagnosis after becoming malnourished trying to follow Dr recommended diets for high cholesterol, pre diabetes, CKD 3 which is usually functioning at 2 level. None of them were congruent and resulted in my becoming malnourished with HGSOC appearing not to awfully long after. I came to the conclusion that moderation of primarily healthy non GMO, organic food cooked at home like my great grandparents grew, hunted and ate seems to work the best for me That even includes some hand cranked homemade Ice cream on occasion😉😁 I can't to that conclusion when I sat in front of a dietician and said what the hell can I eat that I'm willing to put into my mouth and she was literally stunned because she said I see your dilemma. 🙄
Remember that they don't have to tell you about all the studies that happened with no results before they got the results they wanted. They can run study after study showing nothing or negative effects and if they finally get one that shows something positive for the product they're trying to push that's the one they publish
🔥
@@1plus1equals25 then get it peer reviewed
The hand-in-hand with this problem, or possibly the bigger issue is that journals won't publish papers that show no change. If you run an experiment and you don't get a positive significant result they ask you to do more studies to get some results. Obviously, if the research was shabbily done it needs more work, so it makes sense to ask for more experiments. We don't necessarily need every single failed idea published but if it was quality work and they tried to solve it a few ways and still didn't see anything, and it showed no significant effect that still matters. If we could see how many ideas have been tested that failed we could quit testing the same ideas over and over again and save a lot of resources.
Consuming whole real food (minimally processed - minimally sprayed) prepared in a traditional manner (generally - low and slow) is probably the best advise given to us by our ancestors.
People often forget that are lifespans increased in the 20th century because we cleaned up our drinking water and developed antibiotics to help with surviving fatal infections.
Very true, and in the past humans would consistently fast especially in winter, whether we wanted it or not. That has an amazing effect in repairing and bolstering the immune system, which not only fights infection but the damage of aging and clearing out foreign materials.
And daily activity that kept muscles strong and flexible
@LTPottenger Really? Evidence from human trials, please?
Generally agree but the idea that “low and slow” applied to vegetables and fruits is clearly erroneous. It has resulted in generations of people who hated the resultant mush.
The Chinese clearly know that most vegetables should be cooked quickly (stir frying) or minimally (added to soups or noodles at the last minute).
Yes, at very least we should start with “clean” whole, and unprocessed foods. Then we need some minimal social and happiness in our lives.
Geez!! My grands lived into their nineties. No meds unless it was absolutely necessary. Me, same way. Food is medicine
I agree with you. And would like to add that we have lot more toxins from varied sources, not just from the pollution.
Yes!!
Everything in moderation. My folks had FRIED eggs, sausage, and biscuits with gravy every morning. Pie and coffee in the afternoon, and a pretty good size dinner of meat, veggies, and bread for dinner. Always dessert. They did crossword puzzles and read obsessively. They walked and laughed. No drugs. They were sharp, trim, and lived to old age.
❤
A nice anecdotal story. There can be exceptions.
@@Drowning_Girltrying to sound smart huh.
@@sillymesilly nothing wrong with thinking critically.
Well, my dad, now a relatively healthy 93 , drank alcohol like a fish from a very early age and he is still sipping.
I wish I had listened to my grandmother’s nutrition advice. I had a baby in 1995, and we were so strict with a low fat diet. He refused to eat baby food, only drink his smelly soy formula. My grandma said, “He needs salt and fat.” What did she know? She never even attended high school! I would give anything to go back and feed that baby smashed human food with salt and fat, instead of the recommended Gerber jars of puréed slop.
I had 5 children, breast feed them all and smashed up whatever we were eating. Worked for us.
This has a lot to do with the epidemic of “add” , “generalized anxiety”and other assorted horse crap diagnoses.
In 1972 I had a little hand cranked baby food grinder. I would grind up meat and such. I would give them as baby gifts but sure they were never used.
@@junkgirltoo5005 I had one of those too and used it.
My parents had one of those, they used for all three kids.
This doctor is the only doctor that I can listen to in its entirety because he speaks quickly. 😂
I listen to him at 1.75 rate. It's kinda fun.
Yes! There are some I have to speed up, then they sound 'normal.' lol
If you turn on the closed captions, you can squeeze the maximum speed out of the presentation, because the printed words, even though they are sometimes wrong, give enough of a hint to fill in any blanks in comprehension the speed causes. And of course, hitting the space bar to stop on complex things like graphs, and even occasionally having to use the left arrow to skip back 5 seconds and repeat.
I’ve tried to stay healthy over the years but when I heard how these survey studies were done I realized there is no science to nutrition “science “.
I think that's basically most scientific studies. Follow the money.
@mr.giggles4995
So much more money in treating symptoms with drugs that are addictive & that can be patented, rather than focusing on healing at the cause or as a whole using nature/nutrition. It's a disgrace.
As a Registered Dietitian, we do our best but I have to say you are right. What is our best available evidence? It not only changes, it REVERSES every decade or so.
cry1 lectin binding proteins
Registered Dietary Association is Owned by BigFood.
Evidence isn't science. Sciences is experimental. All experimental science in nutrition shows the opposite of what doctors and dieticians promote, which are decided by corporate interests. LDL is good for you, replacing saturated fat with PUFAs causes extremely elevated all cause mortality. And much more. All with high quality experimental data including from Ancel Keys himself, which he suppressed when he did not get the desired result.
Eat real food, not too much, mostly plants. Michael Pollan
The best available evidence is the traditional diet system. There are no ‘studies’ to back it up obviously but the fact is that it has endured through centuries. Modern people are having to return to traditional dietary practices like eating fermented foods after suffering poor health following modern dietary advice. People are noticing considerable improvements to their health, especially their gut health and bowel movements after consuming fermented foods.
Same can be said of psychological research. As a psychologist, this really anders and saddens me. There has been and will always be biases in research, but it has grown exponentially over the past several years. It's not just big money but big ideology. Politics and beliefs have permeated the research and the sainted APA who advocates for political policies based on ideology rather than actual science. The DSM doesn't even reflect what the experts advocate in some areas and some of the best minds that wanted to contribute for the good of society have left its advisory group. I've worked in this field for 25 years and I am shocked at what I see being advocated, promotted, and used in clinical settings. Maybe I was too naive and idealistic when I was younger and entered this field, but I never thought I would see what I see going on today.
Don’t be so down: our field gave birth to marketing, nudge and propaganda! We’re awesome 😂😂😂
and they created this expanded idea of asd to deal with the polluted food, never teaching psych people about the biome.
what is it you are seeing being advocated and promoted in clinical settings?
And if you go off script from their (unhealthy ideological) narrative you’re done. It’s tragic for professionals like you and vulnerable patients.
That's unfortunate, but at least children are now able to have their genitals chopped off if they don't want them.
Speaking of confounders, NHANES. It has been shown any number of times that post facto food consumption questionnaires, like NHANES, are highly inaccurate. Which renders any conclusion based on NHANES, or any such questionnaire, highly questionable. Nutritional science is very close to a total disaster area. Vinay is dead on on this one.
Your cartoon was hysterical, and I see that nothing has changed since 1997! I agree with you on Pollen's books and his call to return to basic non-processed foods. If one looks around it is obvious that the majority of us are not eating a proper wholesome diet. Another observation since I have had the benefit of personal observation through 7 decades of life. When I was a child, there were no fat people, no one I knew had diabetes, and I never heard the words "autism" nor Alzheimer's. I also never ate at a restaurant until my late teens. All of the above came into my awareness about 1980. What changed then?
Yes. But, gotta chime in: dementia (couldn't tell it from Alzis) existed and people suffered from it. Runs in my family. Obviously, the grannies weren't put in hospitals, though, but "delighted" their families at home. My dad told me many many stories about his "crazy nan". 😅
@@simonspethmann8086 Yes of course I assume that things such as dementia existed. As I grew up I learned that older people can be "forgetful", and some children needed special classes for their learning disabilities. It is just that there were really no special labels for those problems. Still these things were not a part of the general awareness of a community. As you suggest, most of the time no doubt they were handled in a home environment. I am not saying my observations reflect reality. I am only relating the state of our culture from over 50 years ago that I personally witnessed. Contrast that with today's reality.
gly in the food started in the 80's..... see the spike in soda drinking 85-1987..... when guys started putting earrings in their ears.... first indications of endocrine system targeting..... see now
@@simonspethmann8086 agree.They just termed it as SENILE back then. The labels came later..so big RX could come out with a pill to mask symptom. $$$$$$
Ice cream is superfood because I like it!
😂👍
mee toooooo!
My German grandparents encouraged me to eat ice cream. There is some reasonable things to say about it, as it does contain protein, healthy fat, but mainly calcium. Basically milk. Now we know about sugar, which is not great but back then, sugar was not a regular part of our diet and ice cream was a rare treat.
@@cellgrrl healthy fat??😂
You’re a superfood.
Last year I was involved in a keto diet study through our local university. The study was obviously set up to be biased in that the diet that I was given to eat every day was clearly not ketogenic and was instead an ad can style high protein diet. I'm not sure why. The researcher decided to use this but when I pointed out that the food they were giving me was not in fact a high fat diet and I was not able to get into ketosis, they kicked me out of study. Only someone who knew what a ketogenic diet was and had been in the study would even know at the end that the study was not actually testing a ketogenic diet. My impression was at the researcher wanted grant money because keto is super popular right now but didn't actually want to get people that much fat in their diet, and maybe she also knew that I had high protein diet would be harder on the kidneys than a high fat diet.
unless your at stage 4 kidney damage the protein should not be an issue, various trials were done with this to indicate this is more a fallacy. With Keto there is much discussion within the community that protein is too low as people are chasing those ketone readings. This has some association (not really strongly validated like most nutritional science) with thyroid dysfunction is over an extended period of time. So the idea has been high fat and moderate protein, perhaps one higher protein serve a day and higher fat meals or snacks outside of that.
Now onto a more specific issue with high protein and this is really more to do with the differences in sex where women (and this can also be true all the way back to some of the primates) tended to gravitate towards more fat/carbs than the males, even then there is great differences between an individual tolerances and requirements for fats and proteins when talking about low carb diets in general. This makes very strict diets very hard to follow which either causes increase drop outs (often allowing the researchers to make claims the diet in a broad sense is very hard to maintain or follow even though they enforced a very strict version of it) or adverse outcomes.
Not as much an issue with Keto trials but certainly the low carb ones is their definition of what a low carb diet is. An example would be much of the research on negative outcomes of low carb diets are done on people eating between 26-45% carbs, by no means the idea of low carb but slightly lower than the average intake. As nutritionist Dave Macleod covered on his video on ketogenic diets and sports performance 35% carbs would cover some pizzas donuts etc or foods we would class as some of the worst combinations of processed ingredients.
Vinay, you make me happy every day! I simply ADORE you; what you think, say, argue, and delightfully shove under a few bright noses and brains! Bravo!
Outstanding presentation, Dr. Prasad. It would be really interesting if you could do a video on how unbelievably SCREWED UP all the so called "research" was over the last 50-60 years as regards STATINS and CARDIOVASCULAR DISEASE.
I’m interested to know … are statins good or bad because I see so many opposing videos right here on UA-cam
One day they say we are eating too much bacon grease, and the next day they say we aren't getting enough.
What I learned in the first semester of college journalism class- the goal is to "sell papers" = income for the press comes from advertising. So they print anything to get a person either stirred up or feeling good or worried to get readership, whether it's accurate or not. Liberal press takes it to the extreme, hence I don't spend a dime on it, believe any of it. This also extends to broadcast media. Follow Grandma's advice and furthermore, take note of her genetics and cooking/exercise habits and go from there. 😉
They don't make money selling papers, they take a loss. They make their money serving corporate interests and promoting agendas. The media exists to influence only, not to inform.
Vinay it’s like you read my mind man. I have been going deep on bs nutritional studies the past week.
You are such a gem to society, Dr. Prasad. Keep these coming!!
Yes the nutrition science flip flopping reminds me of Hollywood recreating classic movies, like The Color Purple, Coming to America, Halloween etc because they cannot create new story lines. No one can sit down and be creative because our attention spans have been devastated by social media (Tik Tok etc) has done a number on us. Did anyone make it to the end of this comment? 😅❤
A brand new study shows that life is actually slowly killing you.
i’m middle aged now - I don’t pay attention to any of this stuff. common sense says just avoid junk and eat some veggies.
The issue here isn’t isolated to nutritional science OR observational studies. Vinay does not understand that the misapplication of statistics is making observational studies and RCTs in both nutritional science and modern medicine completely useless.
The best summary I’ve found addressing Vijay’s misunderstanding:
“The problem is that the brand of statistics used for "evidence-based medicine" is junk, and that includes his beloved RCTs.
The reason nutritional science sucks is the same reason as modern medicine. They isolate a specific question in a chaotic system and try to give definitive broadly-applicable answers. Answers that often don’t exist.”
-Alexandros Marinos
Yes yes yes thank you. And in addition he trusts the science from the same people and institutions that he openly calls out for bad and dishonest practices and poor management. And then the next week he is reporting on a study by one of those parties and acting as if the data and conclusions are credible.
So now we know that the Well section of the New York Times is as wrong as what is usually on the front page.
Honestly, sometimes I drift off, but I could listen to Dr. Prasad all day. I usually have to replay the episodes to absorb all of the great information he shares. 😊
Gary Taubes tried to open the eyes of nutrition consumers fifteen years ago about the almost insurmountable problems with retrospective observational epidemiology in nutrition. .Even as simple as who can possibly accurately remember how many times a week in the last year they ate broccoli. And then all the many things that you speak about. Problem is, controlled nutrition trials are super difficult to manage with subjects living in the wild, and metabolic ward studies are just too expensive to do with large n's or over long periods of time. And, I had to chuckle when you took a shot at Well. Thank you for being another voice warning about believing that column.
Very pleased to see you finally tackle this topic. If I had to pick the most-overhyped thing of them all it might be green tea. As much as I love drinking it myself, I don't necessarily give in to all the hype about its purported longevity boosting or weight loss effects.
I completely agree with your points here 😊
And will add that inviting RFK onto your podcast would be of huge societal benefit. I trust you to be able to listen and bring your thinking and knowledge to that discussion
Great video! Too bad you are right on!
The population is changing so fast with regards to metabolic syndrome that we can’t even rely on our grandmother’s advice.
Covid policies made things worse with regards to metabolic syndrome.
The only reason you can't count on grandmas advice is because the food isn't the same .In her time there was no GMO and a pending on your age they may not have been eating vegetables without Monsanto's help and the animals you eat weren't pumped full of antibiotics. Yet everything she said was correct the food is just different.Back thin they were trying to help you today all they want is money and to keep you sick.
@@frances1503 Exactly! Our soils are depleted of natural minerals, our food is genetically modified and saturated in chemicals. It keeps big pharma and doctors rich and is sick and poor.
My grandmother said "margarine is good for you!".
That had to be during the 70's when it was believed that animal saturated fat caused elevated cholesterol. And margarine was much cheaper than butter. As usual we learn later that was untrue. I think Grandma was listening to the "science" at that time.
@@cellgrrl That's right. I was about 5 or 6, and it was New Zealand around 1977, 1978. My guess is she would have got it from TV or newspapers.
completely agree, inundated with conflicting info, so much so i switch off now it is ridiculous, i am glad you discussed this
Mi esposa is obsessed with "nutrition science." I thought about sharing this video with her, but there would be no peace in my home if I did!
I want to say that the only dietary study headline I’ve ever seen that was 100% accurate was the headline “Study shows that eating food for 100 years will lead to death”
But only in 99.7 percent of people
One big problem is often that things are over simplified like "vit E increases all cause mortality" but in what concentrations?
Grandmama warned me away from booze.
Only problem with "grandma advice"-if you were urged to "take what you want but eat what you take" or part of "clean plate club" it teaches you to IGNORE your body's satiety signals and leads to overeating-grandma was MOSTLY right but NOT always!! Parents do this to kids ALL THE TIME and it is leading to obesity!
My mom did this but also added, don't take so much, you can always go get more..
When the diet coke commercial first came out and no one could taste the difference - I ran out, tried it and boy there sure was a difference! Next one was the more expensive no fat cookies and the more expensive watered down lite beer - haven't paid attention to this kind of stuff since those days because it tastes like crap.
My great grandparents were farmers and they didn't eat tons of different kinds of of fruits and veggies. They ate what they grew and traded with other farmers for some variety. They always grew the 3 sisters, wheat, green beans, sorgham, pork, chickens, foraged, fished and hunted. One had an apple tree, the other a peach tree. One G G-Pa made white lightening, the other corn whiskey and they smoked the long green tobacco they grew themselves and smoked it in corn cob pipes.🤣 They lived into their 90's. What they didn't do was genetically modify their food or use chemical pesticides on it. They salted and smoked their meat, dried their veggies, and enjoyed fruit in season. Coffee was a treat due to cost and availability, and drank a cup of green tea daily if they had it and lots of water.
I'm a doctoral candidate in a non-medical field, and find this so helpful thanks.
My mother lived through the depression and the one summer they had milk from the cow and flour etc. They had a lot of whipped cream in a pie shell that year. She lived to be 90. And so did her siblings that didn’t smoke.
Give it another 30 years and we will have a good read on clean/organic foods and longevity. All you youngsters will have to do is watch when those of us retiring presently drop dead. It’s to bad I’m not likely to be around to see what happens
"Organic" is another fad scam. Virtue signaling for the rich...
Nutritional Science = crickets are good, beef is bad.
Wonderful lecture. I had, for various reasons, concluded that nutritional science is the toxic waste of junk science. This video explains some of the bigger problems in a clear, easily understood and convincing manner. Nicely done.
My grandfather was a home builder and a weekend alcoholic, and ate one or two eggs a day, cooked in butter, with one piece of toast, and he lived well into his 80's until my grandmother died, then he took his own life using pharmaceutical drugs mixed with alcohol on purpose. He was fit, had his right mind, and was always in control of his life to the very end 🎉
I would never trust the NY Times for anything.
"Eat food, mostly plants, and not too much"
Crazy! Why mostly plants? Animal foods are way more nutritious and the nutrients are way more bio-available

Because everyone that identifying different than what I said. Needs to make it CLEAR what they identify as or stand for. 3 years ago I never would have thought of it being a issue because I really don't care about people's personal preferences. But now it's the biggest issue. Handling people's problems with how they are addressed seems like the most important thing to some. I apologize if it bothers you but I am so used to having to address people accordingly. If I had the ability to end all this Bullshit it would be my focus. Just like the fool that has a issue with religion/respect for others beliefs.

Really enjoyed this video. Focused presentation, clear summary at the end. I appreciate how you mentioned traditional diets are generally going to be good for you regardless of culture. Often times I feel like we are "discovering" the nutrition science that our ancestors already recognized. These people weren't stupid, they understood quite a bit of nutrition. They just expressed that knowledge in a different way
They also had to survive in varied conditions and had to make do with what grew there or they could adapt to.
I found this an enlightening and humorous video. When I was younger and going through some health problems, the most useful piece of advice that I received came from a dietician. I was asking her about the silver bullet for good health. Her advice that I still follow today was moderation rather than trying to find the silver bullet for good health. So, I pretty much have learned to eat what I enjoy, but in moderation. Still not the answer that I was looking for, but it has been a manageable piece of advice.
Good advice! I'd like to see a study comparing people who eat a high protein diet compared to those who mostly eat a plant based diet. Meat has gotten a bad rap in the last few years, but we're also seeing many plant-based diet people switching to a protein diet and feeling better.
Indeed one of the best advices: if you leave it outside and no bacteria or fungus touches it: dont touch it yourself.
I wrote software many years ago for media sellers like TV radio print and cable. They depended on ad sales and they bought a lot of research studies that simply asked people a bunch of questions, often hundreds of questions. I took those studies and literally showed where a media seller like a radio station could see where his station indexed high. And where he indexed low. To index means that your audience is more likely than the average station to do something. I called this Story Finder. And any radio station could find a product that his audience favored. Or some sliver of his audience like females or teenagers favored. The reality is just by random chance you could find lots of stories promoting your station. But because it was often chance, the advantage would disappear the next year. We called this overfit. You see in data there are always random anomalies that tell a false story. You can tell whether something is a random anomaly simply by testing the result with a new study geared to test that result. Often our researchers and drug/food companies do not retest to verify their study. They are happy to let the random chance stand as fact. I sold this software to thousands of clients. Ad sales is a buyer beware industry. I guess health is also a buyer beware industry.
Moderation in everything...Dad's advice.
You are a gem.
I wish you were my doctor. God bless you Dr. Vinay Prasad. What a cool name. It sounds more French than Vivek Ramaswamy and i love that guy too. Semper Fi
Always a pleasure listening to a real pro 👏
If your friend is in Harvard it doesn't mean that he is doing quality research. He is clearly capable of doing great research, but does he ask correct questions or shitty politically correct statements, which he wants to "prove" by manipulating data? Vinay asks real questions, he doesn't lie. I don't have much respect for "scientists" who can do sophisticated, well-polished garbage.
Yeah. Much of science is sophistry now, unfortunately.
My favorite doctor! The only one I listen to.
whatever you do.. don't eat eggs with strawberries 😣
This is definitely a "share with the family" (but particularly the smart, very inquisitive ones!) video. Talk about new nutritional info, THIS IS IT!🎉 Thank you, Vinay!
wow i'm dumbfounded by the rare quality of your analysis here, and elsewhere. this is so good. why don't you have 1M subs yet? you give me hope. lol. keep it up please. you got skills. you need a breakout moment. a rogan moment or something like that. thanks man. so impressed. push push push! nobody is doing it this well. i guess it is your advanced terminology that limits your following. but damn i hope you find a way to bridge that gap. you have it.
I had an endocrinologist threaten to dismiss us because I had "keto egg muffins" listed on my Type 1 Diabetic son's food diary. For people who have what amounts to an inability to process carbohydrates, it's very interesting that they would threaten you for giving your child more fat and protein instead of pancakes and cereal. We have a different doctor now, btw. The one at Vandy was an idiot.
Thank you doctor for asking the important questions, like “Should I be lining up at Costco to buy the world’s largest bottle of vitamin E?”
how about saturated fat vs seed oils, margarine vs butter, etc, etc.
pubmed.ncbi.nlm.nih.gov/27071971/
There's 2-3 like this I think and they are very old studies which only recently surfaced. Doesn't look like anybody wants to publish results showing animal fats are not that bad.
I was worried to watch this and lose faith in VP, bc nutrition is very important. Glad I watched. Vinay went full snark against MSM garbage😅
I did my degree in dietetics and even without being trained in science by them I was absolutely APPALLED by the poor quality of the vast majority of the research. The nutritional dogma based on crap data was too much for me by to handle and I had to leave the field and went into immunology instead
The only use for the New York Slime..
Is starting a fire.
The academic community has to be political correct.
Vinay, I always appreciate your fearlessness in sharing your viewpoint.
A good pairing to this podcast would be the metrics collected by hospitals and doctors to pat themselves on the back with little evidence.
This would be the text message, or email surveys, which arrive within hours, if not minutes, of a doctor visit or procedure. I’ve just met the doctor for the first time. As most appointments go, it was a whirlwind, you come out armed with a plan that you hope to God will work, and the doctor was pleasant. So how do you not give the doctor high marks? You’d have to be a pessimist to be critical at this point. A few days, or a week later, you realize that there were misunderstandings, or you are lacking answers to critical questions that the average person would hope a doctor would cover since they are the doctor. How do you get that survey retracted to give them an accurate rating? You can’t. You have to initiate a complaint that will take a huge effort to get any satisfaction. How many statistics do we read that come from these inadequate surveys?
These days I wait until the treatment is complete and handwrite a note to the doctor, or even their superiors. Trust and credibility are earned over time. How do we bear pressure on institutions to compete with each other for the high hanging fruit?
Most healthcare systems have been gobbled up as monopolies. Example- Duke Healthcare vs UNC Healthcare
Wake Healthcare vs Vidant Healthcare
My Dad ate bacon/sausage, eggs and fried potatoes every day and lived to be 92. Only real butter in our house. Raw milk when we could get it.
Why would anyone read the newspapers for Nutrition-related topics?
Experts in the LCHF, keto, low carb & carnivore community have been saying this for decades. I highly recommend Nina Teicholz excellent book - The Big Fat Surprise
The only surprise is how much of the book is plagiarized and inaccurate.

and part 2.
This was a really informative take, thank you! But what is the final suggestion here for researchers? If nutritional population data analyses and laboratory testing have too low credibility-how are we supposed to determine optimum/avoid harmful diets? Nutritional information is crucial for health and society. It informs and influences what people eat, what parents feed children, government and healthcare guidelines, school meals, and nutritional food standards. Grandma's advice-eating foods with fewer ingredients, less processing, and lower quantity overall-is helpful for adult individuals, but with only grandma's advice we also had issues like Rickets. Nutritional science has helped us significantly by giving guidelines for macro and micronutrient requirements that improve on grandma's advice. Nutrition is a fundamental aspect of lifestyle for health and quality of life, and it should have an appropriate research focus.
I've always been very suspicious of studies that treat nutrients as drugs. When a clinical trial is done on a new drug under FDA supervision, it is manufacturer-specific and enrolls only patients who have the disease that the drug was designed to treat. Neither of these conditions are met in the nutrient clinical trials run to set government policy, so it's hard to tell what the results mean. We already know, though, that those with deficiencies of a particular nutrient are more likely to benefit from taking supplements containing it than those without. The questions we should be asking should be related to the dose: What is ideal? What is too much?
And re eggs: how many of those studies distinguished between the effects of soft-boiled eggs and those that are fried ... with butter or vegetable oil?
THANK YOU for mentioning Michael Pollan (AND most grandmothers…I had one that pretty large, but she loved her bread and sweets), his line was the most important, bottom line, take away of this podcast! There is so much logic in the benefits or downsides of what we eat. We’re in a nice area of Florida for a few days, and we’re seeing many many people of all ages…also many in swimsuits… and I’m absolutely horrified by the body fat on most. Clearly plants are NOT the bulk of grocery cart contents or the predominant item on menus. 🤦♀️
thank you for addressing this topic
The most important lesson I learned from my father and also later in my 20s was to completely disregard the media. Journalists arent competent people and theyre even less trustworthy. In fact theyre the moral and intellectual bottom of society. My mother trusted the media like her mother trusted the church, and I believe she paid with a very early death for it. Im pretty sure that trust in the media is one of the greatest reducers of life expectancy, both individually as well as collectively. Not only the affected individuals but our whole societies will suffer greately from the infantility of the vast majority of people in western countries.
I would put most TV, cable and news "reporters" right down there with used car salesmen when it comes to knowledge, veracity and accurate interpretation of data. AMEN!!!
Basically my view on it. Nice to have the research now that I can point to explaining the problem.
this is nothing new. I noticed this 30 years ago and stopped paying attention to it
So I am new on your Channel and this is my first video. I must say it's provocative, but mostly true. As someone who is working in these areas, I can boldly say that the main problem with most nutritional epidemiology studies is selective reporting bias due to multiple vested interests. This issue also affect other health sciences. There is nothing wrong with differences in covariates included in epidemiological models because epidemiological studies cannot measure covariates in the same magnitude and direction even in samplings from the same population. Population-specific adherence or proclivities differs as well. There are other factors to discuss as well. However, to conclude that studies in nutritional science lacks credibility mainly due to these investigator-related biases is utterly untrue. It's giving the dog a bad name to hang it. There are still good science and scientists in nutrition out there. The problem is how can we empower common people in interpreting nutritional epidemiological studies to make well informed decision of their choice, without being entangled in the jargons. This is a good video every college nutrition student should watch. Thank you.
I get what Dr. Prada is saying about the flawed system; however I would ask medical professionals, “Are you healers or pill rollers?” When I go to see a medical professional and I get “We don’t know what causes your condition, but here’s some pharmaceutical to treat the symptoms “, I’m going to look at nutrition and natural treatments.
The covid vax and face diaper studies showed us all how worthless all of these studies are. The biggest problem with peer review are the peers.
Wisdom is almost non-existent in the current age.
@@SC-gw8np As well as common sense and survival instinct.
....always some comedic relief with the underlying elements of sarcasm, cynicism and mild mockery. 😂

Yeah, I'm one of those "study" guinea pigs. Twice a year I get one of those nutritional surveys that ask what I've eaten recently (usually over the past 3 months). I was sent a scale which I weigh-in every day. The problem with the nutritional study is that my food changes a lot over the seasons (and years). Over winter holidays I eat a lot more junk food. When I'm training for a marathon I eat a lot of veggies and take supplements. A couple years ago I tried a keto diet for a few weeks and absolutely hated it. I'm now eating WFPB, which I like a lot. So if I get hit by a bus tomorrow or have a heart attack, will the WFPB diet be to blame? I can't imagine how researchers might sort it out.
Your "data" should be thrown out obviously. As well as all the others.
@@kbaz6658 I'm not so sure. My study (so I was told) is about weight control, more than specific nutritional supplements. I've never been obese or diabetic (knock on wood) and they seem to want to know why LOL.
Keto made me feel like crap after a month. Long term it’s not a good idea
Just the topic I've been questioning again
It's so frustrating, and not just humans
I was looking into adopting a dog, went deep dive into spay/neuter/gonadectomy vs other sterilization methods like vastecomy that preserve hormones. There's this big socioeconomic issues that result in well off people tending to own spay/neutered dogs, and low income folk owning intact dogs... and the vast majority of longevity and behaviour studies don't account for this... resulting in conclusions like "intact dogs have a shorter lifespan" ... but when look into it hey die of infections more , they have riskier lives with less veterinary access. Worse, via human and rodent studies, depression, and anxiety is a sometimes side effect of gonadectomy, but not a single study assesses depression. They only assess behaviour via mostly owner input, so anxiety is studied as it contributes to behaviour issues, and the results of that is conflicting with some studies showing more issues, some less, some not -- but that's likely in part due to socioeconomics also (lacking resources contributes to behaviour issues). There are some advantages around removing hormones in dogs as it def seems to reduce some disease and undesirable behaviour, but it may be increasing other behaviour and health issues more then it helps (See parsemus foundation's page on hormone sparing sterilization for the research that indicate that may be happening), but really ... need better studies that properly account for lifestyle/poverty/vet access/size of dog (large dogs mature more slowly but age faster/die sooner -- due to need for guard dogs, low income households tend to have larger dogs per some studies).. So atm, vets and and shelters are using data that is likely a result of poverty more then hormones, and what's concerning is that is behaviour and health issues increases rehoming/the welfare of the dogs/etc. ... So cannot even make good major health choices for our pets :x
The best we have for science in nutrition is hard endpoints with extreme surveillance... and we still manage to screw it up if we let people select their controls. You're right about ‘what grandma told you’, although you should go back a few more generations at this point.
Tradition allows you to discover which diets survive and which don't; one downside of globalization is that a lot of people no longer have culinary traditions at all, and especially people who didn't learn to cook from a particular person.
The best way to do a multivariate analysis like you described is to normalize for ALL of the available values in the record that are not systematically inaccurate; as for the endpoint design, I like selecting a target death age, since there's not really any meaningful quantitative relationship between the quality of dying in your 20s and that of dying in your 80s. Hand picking the controls is great for discovering headline grabbers, but as you point out, it combines with publication bias.
Also since, eating animals vs. not eating them is a political matter that correlates with the political core of western academia.
Love the video. One thing not pressed hard until the end, was the confounding of funding incentives for research outcomes.
My father’s side of the family should be studied. They all ate plenty of fruit, vegetables, beans, cornbread, and lots of fat in the form of real milk, butter, and straight up lard. My grandmother would make bacon for breakfast often and would cook her eggs in the bacon grease. They were all very active until old age. No dementia, no heart attacks, no strokes. They all lived well into their 90s. My great grandmother was 108 when she passed.
"They were very active"
that's the key
Lordy, spot on. As a mom of a child who has been suffering with IBS all her life I’m a living testament to the fact that my grandma’s vegetable soup recipe is the only thing she can eat without having pain, bloating, and other symptoms. Grandma healed herself from colon cancer with that soup back in the 70’s. Wash, peel, and soak the veggies, onion, garlic, cabbage, pepper and tumeric. A beef bone or some chicken if you want. I make it often.
Thanks for your debate regarding the importance of accurate nutrition information, past vs present views.
Good content, good presentation, nice clean shaven image. Keep up the good work young man.
Maybe the only thing as the takeaway here is that Vinay shaved. lol
Good job Doc! 👏🏼👏🏼👏🏼👍🏻
Every poor study has its source in two problems:
1. Greed
2. More greed.
Whatever is said about nutrition, you can read the exact opposite next week. Fact.
You walk into the doctors office and sit down. You say you don't feel so well. Doctor asks what are your 5 favorite foods. You reply then the doctor replies, if you give those up you will feel better. You walk out and feel better already.
I don't know lol that was kinda what happen to my husband when diagnosed with Celiac's disease but he still doesn't feel much better on all the tasteless gluten free baked goods.
There is also a lot of unexamined psychology behind nutrition obsessions - like the illusion of reversing, halting, or refuting aging. Or denying or postponing death, or the inevitability of death. Or a way (a largely ineffective way) of dealing with the unresolved or incompletely resolved issue of death. Or the illusion of perpetual health and happiness. Or a trouble-free life. The illusion that intervention X will bring some kind of real happiness or resolution, or will solve your problem or problems. The illusion that X is the intervention or solution you need....
When it's mostly just snake-oil salesmanship and snake-oil consumerism all over again.
Thanks for the giggle while I work
