- Carbohydrates, fats, proteins. Each person is different, and every body utilizes food in a different way. That’s why a personalized diet can help you lose weight, and give you more energy.
Now, scientists around the world are working on a precision formula tailored to the individual. Can DNA tests and analyses of the microbiome determine the ideal diet for each person’s health?
Many people know that elevated blood sugar levels can lead to obesity and trigger type 2 diabetes mellitus. "Far less well known is that, for each person, different foods drive up blood sugar levels," says Prof. Christian Sina, director of the Institute of Nutritional Medicine at the University Hospital of Schleswig-Holstein. "It makes no sense to divide foods into 'healthy' and 'unhealthy' across the board. Rather, people should be divided into different categories, in order to find out what each individual personally tolerates best."
This research has its foundation in Israel. At the Weizmann Institute of Science in Rehovot, Professor Eran Elinav developed an algorithm that uses stool sample analyses to create individualized dietary recommendations. The algorithm is now part of a nutrition app used by more than 70,000 people.
DNA analyses to create personalized diet plans have been available in Germany for several years, but consumer advocates and scientists have criticized the approach, saying it lacks evidence.

Another great and informative report. This channel has amazed me on content quality that is actually useful and important to all of us. Thank you for keep journalism so helpful.
Thanks a lot for watching and for your positive feedback. We appreciate you taking the time to comment and
are glad you like our content!
More fiber and fermented foods, and less processed foods is my general rule. Highly recommended, supported by science and me ;)
The #properhumandiet seems to work great for 90% of us #meathealsus #seektruth #carnivorewisdom
Check Dr.Adamo eat diet based on your blood type book.
@@carnivorewisdom eliminating fiber, no thanks, vegetables in moderation, this guy is a muppet
@@jerzyk9922 the consensus among scientists is that these diets are unsupported by scientific evidence (links to research on Wikipedia)
@@aRAsgym Not really, what did we evolve to eat? Maybe some veg amd fruit in summer but mostly meat, meat, meat
Individualized nutrition is the future! We hope that more people are able to access to tests like these in the future
Are people generally aware what foods make them feel good (do they know their own bodies without tests)? For me (maybe because of my migraines - I am sensitive to which foods spike my sugar levels (no alcohol ever, no rice, bread, potatoes instead pulses, oats), I know which foods make me feel good - energetic and which foods make me feel bad - lethargic). I've always joked I am a 20 stone person waiting to escape because given a spike in sugar levels just makes me want to eat more! With my twin brother already being pre diabetic my doctor says I need to be careful. I see in my sons their need to be careful with their diets. I am stubbornly 3kg overweight. Being strict with my diet has really helped my migraines. ps. I drink a lot of coffee ! with no effect. Your documentary was very interesting. Until these tests are available - can people listen to their bodies?
@@portiagriffey4403 The individualized testing certainly gives a lot of clues that are hard (if not impossible) to figure out without them. While one could (in theory) find their food intolerances through elimination diets, many don't. The process can also be extremely difficult, alienating, expensive, and triggering for disordered eating.
So many factors are involved in feeling our best/ finding solutions.
For myself (Maria here!) I was able to determine my food migraine triggers because they are common ones (aged cheese, red wine, cured meats), however I still get occasional migraines so maybe there are other foods I havent figured out yet. Or it could be a different trigger entirely. Others on our team have found relief from eczema only through food sensitivity testing.
Bodies are tricky! Science can help :)
Fascinating documentary, learn something new every day 👍
It is good to see someone actually studying the effects rather than just saying something because they know so. I have had type 2 diabetes a little over 10 years now. When I first got it I saw some HORRIBLE - DANGEROUS doctors without any actual training giving advice and recommending too many drugs. I started keeping records of diet, exercise etc. I had one doctor absolutely refuse to look at any of that. I did figure out what I could and couldn't eat though. During that time I found out about the fact that Protein becomes Glucose if eaten in excess. The Keto diet has some good points, but is too heavy on Proteins.
You don't need to consume excess protein.
"Because protein is digested slowly, its impact on blood sugar is relatively low. Additionally, carbohydrates break down directly into glucose, while proteins are broken down into amino acids, which take time to be converted into glucose."
I have polycystic ovary syndrome and I gained excessive weight, I tried several diets to lose weight, in addition to 2 hours of physical activity.
I'm on a carnivore diet, after 2 months my high insulin levels dropped by half and high andeogens reduced significantly
I did Keto when I was over 135 kg, lost weight in the beginning but I transitioned into something more modified. I was eating less starch but not eliminating it, protein was moderate, but more whole foods like veggies and fruit. I lost more weight and felt better. Keto has some good points, but I'm still shocked that people I know that do it eat heaps of red meat, bacon, and not enough vegetables.
It is reversible. After 10 years at a minimum you should be in the pre-diabetic category.
@anandananda9515 ALL carbs do NOT directly breakdown into glucose. This is applicable for simple carbs only.
@@jarikjayhil Red meat and bacon make the world go round. :) I've been on a keto diet for years although I do break it on special occasions when I eat things like cake and ice cream only in very small amounts. So far, so good. I lost 40 pounds and have kept it off. I also have avoided diabetes, which my A1c test shows is borderline prediabetes (whatever that is) but hasn't gone up in years. My new doctor actually recommended a low-carb diet! Things are definitely changing.
excellent documentary as usual, great job DW team. There is an error in the visualization of the SNPs though: the image at 17:40 represents a base mispairing and not a SNP.
I hypothesized that the incidence of gallstones in people of indigenous ancestry in Peru was due to the drastic change from a very low-fat diet to a high-fat diet, which happened in a very short generational time. The numbers of people who have cholecystectomy don't lie.
These studies make me think that there is definitely a relationship. The information about what we eat and what works to keep us alive is stored in our genome and passed on to offspring. By the way, I'm one of those numbers.
We become the places we go to.
High unsaturated fat diet. That must he stated.
I greatly appreciate this very life saving health Docu that back up with science and very details and easily understood.
Keep it up✋️🤍
It is important to practise meaningful eating! No hurry! Carefully chu each bite before to swallow it, for at least 20 times. I was taught this wisdom by my grandmothers since my very early age. Love and peace to all humans!
Always ahead in your presentation on matters of public interest. Great job and well done guys.
Whats best for health is the least processing steps on food possible. The issue is that people & companies make most money where there is the most processing. Clear case where regulation can help.
DW has always been doing a great work with variety of subjects with its documentaries 👏👏👏
Thanks for watching and for the feedback!
Thanks for watching and for the feedback!
In Ayurveda ( ancient Indian medicine) an individual approach is the base . They have 3 body types and each person is a combination of all 3, where 1 type is dominant. Same food and medicine can work differently for each person.
Yes! This method helped me alot after many years chasing around, eat what people/ scientists say good but actually not work for me
Thank you for the information
The food manufacturing industry also needs to be drastically improved, otherwise people will continue to have food allergies etc
We are all poisoned by industry, how far will it go?
@@joebuddy6074 Whenever possible don't buy industrially produced or modified food, specifically not from those big multinationals, such as Nestle or Unilever. They have huge labs which they spend vast resources on, which are busy everyday with finding another ingredient for their recipes that is a little more cheaper, and a little less good for us.
Great information! Thank you.
It's really informative.
I love DW documentaries, but the guy who does the voiceovers sounds exactly like a grown-up version of Nathan from South Park :P
😂
It was a great documentary shared by an excellent ( DW) documentary channel. Documentary about personalized nutrition and types of human genetics +types of intestine Microbiom mixture ,both factors relationships to suger ranges in blood stream of individuals...documentary indirectly labeled to precious advices about human nutrition
Thanks for watching and for your constructive feedback! :-)
Thank you so much!!
I follow DW for such long time. Hello from Florida
Love it. This is the sort of detailed approach that people need to find, or get closer to, their optimal diet. For most things human there are too many variables for a one size fits all approach.
Body and blood type, occupation, urban or rural living, and many more factors to consider.
I love the conclusion closing statement
"We get this essential sugar from our diet" at minute 2.25. At this point I knew this was going to be biochemically inaccurate. There is no carbohydrate that is essential. As you know, there are essential proteins and fatty acids, but there is no requirement for carb to be eaten, as glucose etc. can be synthesized in the body from fats and protein. Oh dear! Two minutes in and they are spouting rubbish. However, I expect it will improve.... maybe. My CGM shows I spike with any carb, so I do not eat more than 20g net carbs a day. I stick with red meat, eggs, cheese and butter, and lost 31kg in a year, and reversed my diabetes and fatty liver, and got my blood results back to normal. I stay keto now. Mood always buoyant, energy good, slim and fit, and I've stopped snoring. Yay! Pass the butter!
Imagine how much healthy food is thrown away in America, yet the price is incredibly high. Why is no one in the industry paying attention to this loss in profit?
i get the idea of eating with time between meals... but maybe the time between meals is an important part of the difference in impact?
idk, its all complicated and there is no reason why we can't get larger participant numbers.......
Thank you for this. So maybe in the future we will get tests that can help us to determine what is the right diet for our systems?

What I've always wanted is just an easy, quick food solution that is nutritionally complete. Like pet food. So i can just buy a few months worth at a time, eat the right amount each day, and never worry about it again. That's what I'm hoping for.
As with most things in life, there's no one size fits all.
😊. PERrrrrrFeeeeCTly said and Done ✅
Very interesting.
Nice channal 😊
As I polish that we love fermentation food and plenty fibre with protein we confirm that is very true.
When was this done ?
The food from my country's region has always kept my body at its best and herbal tea and fruits and veg daily. Lentils, greens lamb chicken fish aubergines potatoes etc. Whenever i eat processed food it has a negative impact. Great documentary!
Informative channal 😊
PBS Nova did this a few years ago. it's emerging science. Since the old model of energy in/energy out is based on burning food to count the Kcals. No one poops ash.
I am wondering what was the app called?
Isrel21c
Only for groups etc
DAY Two
DW documentaries are a quality apart.
Less to no complex sugar and less to no wheat/gluten. This to me is incredibly true.
I am afraid this is too simplistic as the advice is solely based on glucose levels. You should not exclude other benefits of wholegrain bread over white bread. Just because the partcipant had less glycaemic response, you should not recommend eating white bread for healthy individual as wholegrain provides you more dietary fibre, magnesium, B vitamins etc. I believe nutritionists in this documentary know that.
The individual differences in reacting different foods is nothing new. It’s actually published in 2008. Williams et al. British journal of nutrition 2008;100:364-372. You should not call it Personalised if you don’t consider other aspects of diet (eg. Cholesterols, BP, other bloods, and personal preferences & cultural aspects). Dietary advice is more complex than recommending fruit and veges.
I’m quite sure that hamburgers and fatty foods have never been an essential food type. however a lot of Americans seem to see it that way
I would be tempted to cross reference the "junk DNA" with the genetic profile of gut flora to understand how or if this coding is correllated - next research question is simply a mattter of subtraction (assuming computation capability) and determining what percentage of our DNA (along with junk DNA) correlates to or influences gut flora. Such stimulating topics you choose.! I much prefer these docs to straight news or junk videos about personal opinions and emotional reactions.
This is true if you have an autoimmune disease
very interesting topic BUT of course my body will react differently to the burger i ate for dinner compared to my neighbor's chicken and rice.... the monitored participants should've been on a fixed universal diet that's given to them and then only we can see how different bodies react to the same food and maybe investigate why
Everything should be personalized, there's no size fits all.
What was the app?
The for blood sugar response is from the Continuous Glucose Monitor like Freestyle Libre 3
It's called Day Two
I noticed that honey never raised my sugar measurements a long time ago,.Whereas dieticians and literature demonised it. It definitely is ,I am realising an individuals preference to how our body reacts. A very interesting video.
Agave spikes your blood sugar.
Please let us know the name of the app the couple are using.
Apparently, it's called "Day Two"
What happened when they followed the personlized recommendations? Did thier health improve?
Why can't we just fast track personalized nutrition by using A.I.? I think using A.I., we would be able to find out specifically what our bodies are tailored to a perfect personalized nutrition and pinpoint what each person needs. We all know there are a lot of factors why people are the way they are and if they want change, we also need to determine genes differences and everyone is different from one another, and only AI can computate exactly and in a short amount of time to determine what each person needs.
I really appreciate this video. However, the question remains, why our ancestors didn't have this problem? And the simple answer is, NO surplus to the extent we have today and MUCH less screen time. So it's not brain surgery. It's relevant to those who, despite, not being overweight, active, eating a balanced diet and still have issues, like IR and cholesterol. You can only overcome your genes so much.
thank u
Thank you for watching!
Finally west doing what our ancestors had been doing for centuries.! First step in Ayurveda is body type/dosha and eating accordingly.! Life is a full circle.
Not without a gut flora test (main issue with modern diet, no bacteria)
I wonder would this be good for conditions like PCOS ??
That condition makes no sense
Genetic testing will only reveal so much and it'll provide you problem areas and foods to eat or avoid. It's NOT to be used as a crutch or excuse but provide a path to a solution.
A better approach is to consistently check your blood biomarkers and implement a personalized nutrition program based on evidence and science backed knowledge and techniques instead of rules and restrictions. The centerpiece of every nutrition program should be anti-inflammation, gut health and the consumption of nutrient dense high quality whole foods in a balmced manner along with optimal hydration (electrolytes and water). NOT a diet.
With that said you still need discipline, sustainability, internal motivation and consistency. Along with regular physical activity and in some cases Natural, non-gmo herbal (not synthetic) supplementation.
This was somewhat disingenuous because the alternative Sweeteners did NOT include stevia, monk fruit or allulose.
Well
Would be nice to have links to those apps and tests DW... ✌🏼
they will boycott anyhow.
DayTwo app
Day Two
I been saying this since Covid❤
now my stalkers would think that I am diabetic, because I watched this
Where or how to get those tests? How is it called?
Try to google something like microbiome diet testing. Or "nutri-genetics" testing. Or "diet based on genetic analysis."
Day Two is the name of the app. But you'd have to know your blood glucose
Sugary foods are bad in general, in my book. Eating in moderation "good foods" is important as well as maintaining a healthy weight. And exercising is GREAT, best for my age group, 60s and up, bodyweight or what it was called as a kid "calisthenics".
Im currently on the steak buffet diet. I eat at Golden Corral Buffet once per day, everyday for 6 months now. One meal per day ftw!
You would be considered smart if you are not medically obese.
What is the app that was recommended on this video
Day Two
Yes, keto and high fat ruined me and my liver, now I’m on Whole Foods raw vegetables + eggs + fish and limiting red meat as much as possible and now I’m swimming in my old clothes. I’m even still continuing my iced coffee with brown sugar, no telling what it will do if I cut that out too! Keto is not for everyone.
Fruit?
So your body doesn’t like keto whereas another body would agree ?
My migraines are hereditary and coincide with barometric pressure change, but it would be cool if I could see what my glucose levels are when I've got one.
Another key factor that shouldn't be ignored with metabolism diseases is environmental pollution, packet food comes with additives, processed food(ham, sucuk, bacon etc.)and also fresh greens and fruits are subjected to unnatural or processed fertilisers and pesticides. Again, industrialisation has a significant role in changing our metabolism. Stress is another cause of metabolic diseases. Most of us have a sedentary life which also can aggravate the process. These are the downsides of consumer society.
I love DW from Bangladesh
Like many studies before it this one is also terminally flawed because while studying metabolism how is it possible that they did not test metabolic hormones like insulin, leptin, muscle mass, body fat before the study?
I had a recurring migration when I was at 19 years old.
However, it has permanently gone away at the age of 20 due to an hour morning jogging for only 15 days.
Please try what I have done it could work for you as well.
I like my food/plates to be colorful
I don't eat potatoes except once a while... Potato chips
Macaroni salad is not a salad, it has no green!
I follow the blood group eating style. I use smaller portions of foods that are bad for me but which I love (like chicken or tomatoes) and mix it with food good for me. When I don't follow my diet, I become flatulent and constipated and feel sluggish. For vegetables and fruit, I try to eat what is local and in season - and eat it ripe.
Please links to what you’re referring to
I'm no researcher by any means but this group appears to be a rather small anount of study participants to reach a valid conclusion...
How they sequence microbiome while there trillion of bacterial spices? Is it possible to do an eDNA analysis?for individual or that not supposed to work 😅
Excuse me, what is the apps name. I am interested in it.
Day Two
For me Blood-type diet works great doing it now for 18years
Did you do a test for that?
@@ladybug3380 not a medical test... Why is it necessary?
@ladybug3380 there was a book published that claimed you followed different nutrition plans according to your blood type: Type A eats differently than Type B or Type O
App please!!!!!
Day Two
AHHHH The Elephant in the room ,,, race. It would be reasonable to assume a person whose ancestors lived in mostly snow covered lands with little to no access to fruits etc would have a system that is different to someone whose ancestors lived in hot humid fruit growing areas
I tried to eat but intuition of course it means no meat and no white sugar and I do fasting a lot and train sober soon I got 59 years of experience
How we wish everything about life was so simple and categorised! Then, health issues may be more easily resolved and we would not need doctors! What an ideal life! Physical exercise and frequency of meals may also need to be looked at as well as genetics. Never a complete finding about health and diet as ever.
I wish to join that study. I'm practicing a vegan diet.
🤮🤮
Me too. However I am not vegan. However, I do try to consume as little meat as possible. I hope to someday go vegan.
what a painful way to live. they have made existence a chore.
Don't need dieting
How observe what and how much you put in your mouth
I lost weight with that observation
I'd like to add.. mushrooms help with migraines! It doesn't matter if they are fresh or can! =-)
Eat real whole foods
Mostly plant
Not too much
Migraines means metabolism issue, hormones disorder, insulin resistance, also leaky gut...
lol your GP has zero appropriate education on nutrition and especially not on the individual nuances mentioned in the doc that determines what works for someone and what doesn't = makes no sense to consult one about someone's diet.
I wonder if the under-skin monitor of blood sugar has been commercialized 🤔
Anahata ( green)= all plant based ❤❤
I knew this back in the 80's. Re-inventing the past. Not Germany's 1st time.
conclusion: eat less carbs (who would've thought)
Full of Misleading, speculation and scarecrow tactics
So, Kelly Clarkson admitted to lie about diet and simply using Ozempic. My son weights 320 LB, but Ozempic and Wellcare Fidelis denied his RX for drug. He does not qualify for gastric bypass or plastic surgery due to his weight.He needs to be no more than 250lb for plastic surgery. So all these stories about possibilities of loosing wight for anyone with no celebrity status is bullshit.
''I'm not fat, it's genetics!!!'' - Genetics Ice cream since c 1979.
One-size-fits-all treatments are not working, but are profitable. The US spends much more on "healthcare" yet we have the sickest nation -- in spite of having leading technology & many of the best physicians. It's the SYSTEM that does not allow real advancement. But the old bandaid approach of treating symptoms with endless drugs is slowly being exposed and cannot last.
wau you guys are reinventing the Ayurveda medicine, bravo
Fermented food has also its flaws, many veggies have heavy metals now, etc etc its a mess the whole world is contaminated 😢SAD We do what we can but lots of things have to change to clean our environment
Just the fact that there is a hotdog and chips in this video shows the disconnect
