Who would have thought that actual scientific research and a PhD could provide more accurate nutritional advice than a TickTock video?

[ChiselledK]

I’ve noticed that broscientists (like the Gary guy in this video) actually seem to be the ones who are over complicating things.
While evidence based guys like Layne are making topics such as nutrition more straightforward and easy to understand.

[Simone]

Crazy how some people talk out of their butt with so much confidence! Thanks Layne for debunking these trends that have contradictory evidence!

[stormygranzig]

Thank God we have you Layne, way to speak the truth.

Past President of the National Board of Physician Nutrition Specialists here and I learned something in this video! Seems like even Dr. Norton was surprised upon searching that glycemic load is lessened by blending whole fruit. I’ll have to dig into that with other nutrition colleagues, but I’m certainly ready to buy that if you blend whole fruit, keep all of the contents, losing none of the fiber, that there is no significant difference. Besides, comparing blending and drinking whole fruit with going out and eating a bacon egg and cheese biscuit from McDonald’s… I mean come on Gary,

[fiacost]

Non homogenized fruit cocktails, where the fiber is LESS available to digest (soluble and non-soluble), would spike the GI more than the homogenized one where the fibers (both) are broken down to smaller size hence making them MORE available to digestion which would delay sugar absorption. I've made the test using a CMG device strawberry, raspberry and blue berry smoothie (250ml): 6.0 mmol 45' after drinking it; the same fruits cocktail (whole): 6.7 mmol after 45' consumption. That might not apply to everybody out there Thanks Dr Norton; good point, excellent videos 👍👍

3:07 It was in the end of the abstract of the study: "We hypothesize that a reduced glycemic response in blended apple and blackberries compared to whole apple and blackberries might be associated with the release of dietary fiber and nutritive components from ground blackberry seeds." -- Crummett and Grosso, "Postprandial Glycemic Response to Whole Fruit versus Blended Fruit in Healthy, Young Adults"

Your channel has become my favourite since i found it like 2 weeks ago. Excellent stuff.

[Raider]

You know I’m 62 years old. I’ve heard it all seen it all so I was scrolling down and I found your site I was thinking all right who is this guy? After listening to you man you sure do know what you’re talking about. I’m impressed.

[sy]

Joey Diaz was on Rogan saying this about bananas as well. And I think a blended banana should be the least of Joey’s worries on health issues.

[mr-boo]

Thank you for dispelling this common myth that I too started to believe in due to not critically assessing the evidence. It didn’t occur to me that there would be people publicly lying over things that would eventually be fact checked by someone capable. It is just bizarre how much that is happening, especially in claims about nutrition.

Also just wanted to say: loving this friday format. I don’t always habe time for the full videos of my trusted nutrition scientists and this format is regular entertainment and information. Thanks for these and keep up the great work you do against this tide of nutrition information “entropy”

[MrSrBrightside]

One thing you can hold bananas accountable for is that blending flavanol-rich fruits and vegetables with high-PPO food like bananas releases the PPO and destroys the flavanols available. While bananas are delicious and healthy food, if you are trying to consume flavanols, should consider preparing smoothies by combining flavanol-rich fruits like berries with other ingredients that also have a low PPO activity like pineapple, oranges, mango or yogurt.

[ByrdNick]

My a priori intuition was what Gary claimed (in direction, not necessarily magnitude). Thanks for pointing us to the evidence!

[mcfarvo]

"20g of sugar from a banana raises blood sugar more than 5g sucrose in a spoon" wow it's almost like 5g of sugar is less than 20g of sugar

[kingp]

The audio quality! Amazing! It sounds like you got a mic that can support your enthusiasm/volume =)) Also: you're the man, thanks for the great content. Data > feelings and "where's the citation?"

[pass.partout]

From my experience, eating a whole fruit is better than juices, im diagnosed as a type 2 diabetes, and the whole fruit tends to rise less my glucose levels at 1h and 2h postprandial measurements. And yeah, there's something really important not mentioned in the video, the insuline respond, i suspect that a whole fruit rises less the insuline respond than the blended one, a massive insuline respond can explain why glucoose levels seemed lower, for a normal person of course.

[tonybernard]

It makes sense that blended fruit would spike blood sugar more quickly because it doesn't have to be broken down as much as half chewed (because I gobble food too quickly), so I'm glad there's a study and that someone looked it up. I assume that pounding my smoothie with protein powder and full fat yogurt will also dampen the blood glucose response.

[hachetjoel]

Audio quality is sounding great Layne!

[jornhansen]

I guess if the banana is blended it could get absorbed faster because you can swallow it faster, but then again you could have protein powder and fiber powder and a fat source in the shake, which would slow down the absorption again.

Excellent video, we now live in a world where putting out a 30 second tik tok video makes one an expert. There is now cross pollination of channels so the same "experts" (like chiropractors who seem to know how to cure everything) appear everywhere...all claiming their info is "science based"! Thanks for giving us an example of what science based actually means (although not all science is good science)
