"Eat beans" sounds easy enough. But let me help the majority of you who decide to eat more beans/legumes. SPROUT THEM FIRST! I could not handle eating 1 or 2 cups of cooked beans a day because my gas would be so bad. I'm not just talking about farting, but my stomach would really hurt. Then I started sprouting my beans before cooking them, and like magic I have ZERO digestive problems with them. This is why sprouting is a common practice in the rest of the world.
you get used to it. Begin small and then increase over time. Joel Fuhrman talks about this.
I don't have this issue, but it is good to know. thanks
Try to not drink a lot of water with your meal if you get gas, and also as your bacteria increase for beans your body digests them better
@@Austin-ub2gi hello. dr will bulsevis , the fiber doctor says constipation causes gas: ua-cam.com/video/_-IYc6HbPhw/v-deo.html
Sprouting is great.
I find that tempeh (made from beans) does not give me any issues. Tempeh is supposedly even healthier than beans themselves, the tempeh culture partially "digests" the bean and makes it even healthier. I make my own tempeh, it's a great way to get my protein.
Man oh man, these cliffhangers :)
I love listening to dr.greger’s nutrition facts while I’m tucked in, his voice is so relaxing it’s like my bedtime stories:)
ok... now i get it.... my grandmother always used to say never eat fine flour wet or dry of anything.... she always preferred coarse grains, fruits, n vegetables.....
Fascinating stuff, thank you Dr.G
THE SHORT ANSWER: NO
This is the best channel for reinforcing Veganism.
The brain is made up of 60 percent fat...so why are we getting rid of fat in our diet....look at Dr. McDougal what he looks like in his most recent videos....go here for great vegan information ua-cam.com/video/M3zAQJtDIpo/v-deo.html
Greger says you should eat nuts and flax seeds every day...
Vegans could not exist in north america and the arctic in the winter if vegetables were not shipped by truck
from Mexico and California. Vegans did not exist before that.
@@robertkattner1997 Mexico and California are both in North America.
I UA-camd this question, started three different videos and saw your content. Relief. Note to self, start here.
really can not fathom why you aren't the number 1 youtuber on the planet. fascinated
MIND FIN BLOWN on this whole series great work.
So interesting...thanks Dr, Greger!
So can I have a spinach banana pineapple and almond milk smoothie every day?
Good question
This smoothie is way better than any animal foods, such as cow milk, or egg. But to further protect your health, boost your microbiome, and protect your pancreas, try to eat the organic whole fruits and organic whole nuts without too much chewing, and remember to use green tea to wash the mouth afterwards to protect your teeth. God bless!
I am going to make a green smoothy now :) Thanks!
This makes me super happy, I love my low fat hummus and non-fat refried beans! :P
Ok, the cliffhangers are getting weird now....
+Mentat1231 Yeah, but good weird. Right?
+Mentat1231 honestly I think we already have the answer - he said in this video that the micronutrients are preserved during blending and in his "How much fruit is to much" video he stated that it was the micronutrients that keeps the GI from spiking - hence you could eat as much fruit as you wanted. You could even eat fruit with sugar water and see a decrease in GI when compared to drinking sugar water alone.
Im thinking the results will be the same here - if it aids with sugar water it aids with blended fruits
+Mentat1231
More inconvenient than weird.
SuperAtheist
Indeed. I was trying to be nice, but, yeah. It's starting to feel like a big tease.
I like them. Changes it up a little bit. Makes learning a little more exciting, IMO.
Wow!Thank you.Amazing info.Mindblowing
I'm not sure how much you've covered oxalates but I think this is worthy of comment in relation to smoothie diets.. I'm sure many people will not rotate the contents and maybe some direction here would be helpful ? Thank you for the amazing service you provide!
Hummus is love. Hummus is life
Thank you! You just motivated me again to make a JUICE GREEN this morning!
+houndjog
Smoothies > Juices
These are exactly the type of questions I want to see discussed in terms of the "finer points" of following a WFPB diet. Beans, greens and veggies in the blender is one of my favorite ways to make winter soups. But I've been following Caldwell Esselstyn who says "don't put fruit in there!."
Sweet stuff, green smoothies are the way forward!
GREAT video!!! Thanks :-)
Not a fan of these cliffhangers anymore. :)
just the whole nutritionfacts content blows my mind. thank you so mich for spreading the knowledge. #unbelievable
Hi Dr. Greger, I have heard that drinking foods, like smoothies and juices, causes weight gain because of that:
1. The saturation signal becomes deranged when the fuel comes as liquid
2. You get to much sugar in the blood at once, causing the blood sugar first rising and then rapidly decline. And that will make you feel satisfied a shorter time
3.It requires less energy for the digestion
If we make an example. Zack and Julia always eat ten bananas for their lunch. Zack just peels them but Julia always blends them to a smoothie. Lets say they would do this every day in one year. Does that mean that Julia would fell less saturation after her lunch and therefor eat more calories for her dinner and gain more weight than Zack? We assume that those two persons have totally identical bodies, metabolisms and lifestyles.
What do you think about this?
*Unlike grains, blending legumes does not affect their glycemic response.*
Thanks Dr. Gregor. could you do a nutrition fact about phytates in beans and grains.
+Lavern Francis I'd be interested in this too.
+Lavern Francis already did several.
Yay, Hummus! :>
+Haschkeks I was so relieved by that part! : )
me too as i like Hummus. Ive also noticed that it improves my overall bloodsugar so i assumed it was making it all the way thru but glad to hear some evidence.
You are the best, thanks!
what about green juices? please can you do a video about them and their health pros/cons? thanks :)
very interesting video i want to see part two!
+Angela Cummins have you seen part 1 yet? That's good too.
Hey Dr.G will you make videos bout juices too? There's controversy on that also and It would be cool if you could clear that up. Awesome vid btw! Just saved it:)!
I think he did
I'm so conflicted. I hate eating leafy greens so I just spent $60 on a new blender so I could liquefy them and make them easier to consume. Now I'm afraid of starving my gut flora of nutrients. Some guidance would be appreciated.
At 1:36 he says the fiber and nutrients remain intact if blended once they reach the large intestine, so it should still feed the good bacteria.
Damn!I was really waiting for that yes or no lol
Oh man! The suspense is killing me!!! Or is it...?
I'm guessing the blueberries and such in the smoothie help blunt the blood sugar rise. Smoothies are sooo good. The only way to get my granddad to eat his "rabbit food''
its gladiator food. make him watch the yale study vid, or the one bout spartan and gladiators eating mostly barley. SPARTACUS!
I like how Dr Greger ends with a highlight of the next video to add to the suspense. Thumbs up!!
+Stuart Wright It's more clever than asking people to subscribe but I've not been conditioned to wait for much lately so I find it annoying.
+biophiliac9 Consider the amount of work that goes into these videos - not just the readng and researching, but labour intensive writing and editing videos.. I think Dr Greger isn't looking to cause annoying but something to look forward to, but the videos don't materialise out of thin air!
I agree, we are the ones benefiting from the videos, it does not annoy me when someone is telling you how to avoid disease.
Looks like I need more patience and perspective ... thanks for helping with that folks.
my regular morning smoothie is grounded oatmeal, fruits, maple syrup or dates and tbs of vanilla extract. should i stop adding the oatmeal?
Now you've got me curious!
Thanks. I'm super lazy when it comes to greens. I ain't got time for all that. I have to have a green smoothie everyday.
What about those powdered greens that you just add to water, juice, etc and that are so popular (and expensive), are they just as effective, or even more, as eating whole veggies?
I have a Vita Mix and it blends everything and keeps the fiber. I prefer it to the other juicer that removes the fiber.
What about blending porridge oats to go into a smoothie. Does that spike blood sugar
This makes sense. Soy milk, my favorite drink. I feel so great after drinking 500ml of soy milk. Immediately I feel elevated. God bless!
I just got a Vitamix Turboblend VS! :D
+Andréas Remis PLANT BASED VEGAN woot! I have a Vitamix too...one of my favorites to make is Dara Dubinet's raw carrot ginger soup (she's here on youtube)...it is SO delish! In her video, she puts some kind of mushroom in there...I can't even find it around here in Florida so I skip that ingredient.
valnaples I want to try making soups with it too :D What speed do you blend on?
+Andréas Remis PLANT BASED VEGAN for the carrot ginger soup, I start it on low and move it up to high since the carrots particularly are so hard. I think your User's Manual will give you some tips too on soups.
valnaples I'll check it out. Thanks!
+Andréas Remis PLANT BASED VEGAN Das it mang. Cured my Autoimmune disease with blending. Lead me to vegan lifestyle and subsequently Dr. Greger.
I make green smoothies but throw in an avocado with it. Would the fat from the avocado reduce the insulin spike from the fruits?
Massive tease your cliffhangers are, Dr. Greger. "I'm lovin' it."
Got blended legumes?
+zukodude487987 haha cracked me up
This explains benefits of steel-cut oats vs instant oats as well huh
Hey Doc, I barely recognized you without your beard ! :-O
Great video as always! I'm hoping to hear if there's anything we could add to smoothies to prevent that spike in the next few video .
Ppp
Hi Dr. Greger,
I have a question: if you are chewing the fruit VERY well, could that be compared to drink a smoothie slowly and lead to a faster absorption of the sugar or even blood sugar spikes?
In this video, ua-cam.com/video/BARsjJcC8wE/v-deo.html, you say "no matter how much we chew, the nutrients stay attached to the fiber" (1:28). If the nutrients still are attached to the fiber, I suppose that the fructose will do as well? As long as the fructose molecules do not easier get separated? You even say that the nutrients still attach to the fiber after using a high speed blender in 5 minutes (1:40)!? I think it is a bit contradictory when you tell, in your video "are green smoothies good for you", that some nutrients are stuck in the cell walls and can only be released when the fruits and vegetables are disrupted. And thats why blending is a great way to maximize your uptake of nutrients? Though I have read that soluble vitamins are destroyed when you mix them in a blender?
You show that chewing very well, can speed up the absorption of sugar (2:55). "The smaller particles causes faster gastric emptying and produces greater glycemic and IRs". But if we assume that the fiber is still attached to the fructose, that is not the issue. The faster absorption must be caused by that the teeth have helped the digestion with the breakdown of the food, and thats a positive thing!? And if look at smoothies again, it is obviously that the faster consumption leads to a higher blood sugar. If this is the case, then I personally think it is a very strange advice to recommend people with diabetes to not chew their food properly. Instead they could just be told to eat slower!? But chewing very well also means eating during a longer period of time, would not this compensate for the faster sugar absorption caused by eating smaller particles?
Still no word about oxidation when blending? =/
Ooooooooo, waiting for the next video!!!!¡
My guess from all the videos I've watched from you on blood sugar... BERRIES are the key to stunt a fruit smoothie blood sugar spike!
+Wyatt Herbivore ^Extra credit for this guy.
+BeatBay This will be answered in the next video from M.Greger.(Dr.)
But as far as i know -> Berries are good - high fiber / low sugar
BeatBay
No, I meant it as a compliment. Like, you seem to pay attention, so you deserve extra points! That said, I don't know if you're right (we'll have to find out in our next adventure with Dr. Greger lol), but I think you're onto something. Lower calorie fruit like berries are antioxidant rich and the lower cals might mean less of a blood sugar spike.
+BeatBay Berries are one of the best fruits you can eat. The phytonutrients in berries naturally regulate blood sugar. That being said, if you plan to have a high glycemic index/load meal... ALWAYS FOLLOW IT UP with berries to counteract the spike in blood sugar.
+Archie They can, for people whom have blood sugar sensitivities. For example, used to make massive banana date smoothies would feel like crap with no energy, bloating, even pressure in my head. Started replacing by adding berries to the mix... No problem whatsoever anymore and I'm not, nor ever been hypoglycemic nor diabetic.
the cliff hangers are killing me! argg! lol
Please always put in description link to the video that is next. I'm kind of surprised I have to point this out.
Thank you. ✌
No more finding out next! I want INFORMATION NOW!!!!!!!
What does this have to do with smoothies?????
Does the increased bioavailability of blended fruits and vegetables overload any of the processes in the upper GI tract? That's one of the other raps against smoothies.
I'm on the edge of my seat.
I get more out of this channel than all others combined
Yeah! I love my Blendtech! Veggie smoothies are my favorite way to eat veggies. Also, who would blend rice! Yuck. Yeah we get to blend beans!
Summary of the vid: good to blend fruits and veggies and even beans (hummus) but not grains(rice) because they create a huge spike in sugar. Also why "intact whole grains are better than whole grain flours" (quote from his vid). Also, it's not good to chew them really well because they increase the sugar more. So don't chew your rice well hehe
disclaimer: sry for bad english, i am not a native speaker :')
Hey Doc, the physican of my kids recommends to give my baby son melting flakes or baby oats instead of whole oaks. i should do this until he is 3 years old. he sais the reason for this is that little kids cant absorb their nutrions from whole oaks. but those baby oats are a highly processed food in my opinion. can you maybe make a video on plantbased diet for kids age 6 months to 3 years? i am on a whole plantfood based diet since 9 weeks now an feel great. but so confused what to feed my kids now.
AHHHH!! These damn cliffhangers!
Bro that smoothie looks god like
These cliffhangers...I love and hate them!
Lol! The cliff hanger!
What about the temperature of the fruit or veg? I read that if you eat potato salad after it has been chilled overnight that the blood spike is less because it was cold and not warm. I store all my bananas in my fridge to keep them longer and to also avoid fruit flies, but might I also be changing the way the starches react to my system?
Not to much, you need to eat whole foods and warm, just not to many smoothies, they are cold sludge
I have been drinking green smoothies for around 15 years now (most days) somewhat randomly I have been experiencing gas and heartburn and bloating for the last 4 months pretty badly.
I took a 2 week holiday (therefore could not make green smoothies) the gas had got a lot better. I am thinking it must be the smoothies as the gas has come back again when i got home and started drinking them.
I am pretty devasted to stop with my smoothie habit its part of my daily ritual (most days) but it seem to be the culprit of gas.
Has anyone else had this before? Is it because I am getting older (nearly 40) now.
Can anyone give any advice I will be pretty devasted to have to stop with the smoothies and why is it happening now after 15 years?
❤
Chew your Smoothies :)
@0:16 Why isn't kale on the chart?
genioooooo
Dr Gregor does this apply to Green Juices or just smoothies?
Just green smoothies
+Morfeusm hey could you please explain the diff?? i am seeing so many comments but i thought the two were the same??
sn12 Juicing stripps greens of their fibers and nutritiens *merged* with that fiber.
Morfeusm thank you, yeah i saw a few of his interviews alluding to this, but i am still confused. I am not from the us, here we consider the two to be the same. Put everything in a blender and blend. Adding something creamy like milk is what differentiates a smoothie for us. Could you please explain what is considered 'juicing' n 'smoothie' for these vids? the reference Dr.Greger is going by? much appreciated!
sn12 Smoothie is when you blend your food in the blender or food processor. Juice is made by the process called juicing, when you sqeeze liquids out of fruit or the vegetable. Most simple example is when you squeze lemons for lemonade. Most of the people use juicing machines, which hold all non watery parts and only juice comes out.
Hope this helps.
"The real question though is this: What is up with the clean shaven look?
+Santi Anzo No, the real question is are you a moron? And the answer is Yes!
PETER MAINWALD it's an inside joke. Look for rich piana.
Nooo you keep leaving me hanging! Hahaha
Dude! Where's your facial hair in your profile picture? Also, to me it sounds like a little of both would be optimum.
+Patrick Nottingham Okay, so I am not the only one! LOL! At first I was all "But who is that?!
+Patrick Nottingham LOL, Doc took a poll on Facebook last week or the week before...SHAVE or NO SHAVE? The SHAVES won out!
I laughed so hard when I noticed
Dr. Greger, when did you change your profile picture?
Omg
I always chew like crazy and I'm a supee slow eater. I'm also always petite/skinny and always hungry. Could this be 1 reason why? :O
Hi, Vida Blackmoor! Chewing thoroughly and eating slowly can help us to feel full sooner, and to eat less. If you are always hungry, you may want to try adding more satiating foods, such as potatoes. I hope that helps!

@@NutritionFactsOrg thank you! 😁 Potatoes are the best. 🥔💚👍
So green smoothies are ok , but eating veggies is good too. Combining these 2 is best probably..?
it looks like i need way more beans in my diet!
every time I have consumed a green smoothie, I have gotten violently ill. 30 minutes post consumption, I developed a fever and began vomiting. I figured the first time was a fluke, but it kept happening.
because it is releasing pollution into your blood stream
Correction: Sea Vegetables are the most nutritionally packed.
Marine Phytoplankton
Spirulina
Kelp
ect..
Ehm... And the next video is...? No mention of it in the description. 🤷
Is chewing gum really good for you? According to the ADA, chewing trident sugarless gum 20 minutes after eating is preventative in cavities, I think supposedly because of extra the saliva stimulation and the way that the gum picks up bits of food and bacteria and also because it has xylitol which is harmful to bacteria. Do you agree, or disagree, or seen any studies on the benefits of this? Thank you!
This is good to know, maybe I'll leave out the tablespoon of oatmeal from now on.
Gotta soak your beans -DONT FORGET!!
Guessing you haven't read Wheat Belly by Dr Davis?
Smoothies suck !!! I had green smoothies every day for a year ,used to blend everything with great recipes and stuff , started feeling not that good, it progressed to having reactive hypoglycemia even though fruit content was balanced, it developed then to histamine intolerance , heart palpitations and more ... it ruined my gut flora !!! It took me one year to repair the damage . Strangely I was blending and rotating at least 400 g of spinach / kale / parsley etc all organic and the best available and my blood test turned out a disaster : magnesium and other minerals were almost 0 in my blood !!! Never again , human body evolved chewing not blending
one should chew its food till becomes liquid.... blending replaces chewing.... i dont see the problem... maybe veggs should be lightly cooked/steamed
Might be a case for saliva. 30% of starch digestion takes place in the mouth due to the digestive power of saliva. Digestion of fat begins in the mouth due to salivary lipase. en.wikipedia.org/wiki/Saliva
not if you add some good quality hemp protein to your fruit smoothie mix
thumb up if you think that fruit is like beans group
the suspense is killing me!!!
This video proves Dr Esselstyn wrong about smoothies!
it's almost like watching a mystery series or a thriller...
Having seen a couple videos from high carb low fat vegan testing their blood after drinking a big fruit smoothie, I would say that no, blended fruits don't skyrocket blood sugar... But let's see what science has to say about it :-)
Apparently I am way behind. lol
Oh come one, don't leave us hanging!
Though I'm pretty sure green smoothies are very good for you...
