@ScepticalDoctor A large potato has 8g intact fiber. I cannot find info about the bar but it will no be intact I assume but powdered. https://t.co/EklKEraJTq
Oatmeal particle size alters glycemic index but not as a function of gastric emptying rate.

AI synopsis
What people are saying
The group consistently emphasizes that minimal processing and intact fiber are crucial for health, citing examples such as whole oats vs. processed oats, nuts vs. nut oils, and grains vs. powders; their tone and word choice reflect a shared belief in the importance of food structure for both digestion and microbiome health, demonstrating strong consensus and interest in the subject.
Most participants strongly agree that food structure and particle size influence health, digestibility, and microbiome health, referencing specific examples like oats, nuts, and grains.
Discussions are highly engaging, with many exploring scientific concepts, implications for diet choices, and health outcomes, showing widespread curiosity.
Comments delve into detailed explanations about food processes, microbiome effects, and nutritional impacts, indicating deep involvement.
The discussions could influence dietary habits and nutritional thinking by emphasizing the importance of processing and food structure, which are highly relevant topics.
Abstract in brief
- The study found that oat particle size affects the glycemic response, with oat flakes producing a lower blood sugar increase compared to oat flour, due to their more intact structure.
- Differences in gastric emptying partly explain these effects, but the structure of oats influences how quickly they leave the stomach, impacting blood glucose and feelings of fullness.
- Overall, food structure plays an important role in digestion and glycemic response, suggesting that nutritional advice should consider not just what we eat, but how the food's physical form influences digestion.]

@Lainsitzprinz @GardnerPhD Forge the X.Xg/kg protein. Just eat more whole plants or less whole plants for more or less muscle. Everything we eat except jello has complete protein and if you eat more, you get more protein as needed. Not everything we eat has intact fiber #health https://t.co/EklKErsli0 https://t.co/QuXsaJhf3G
@NutritionMadeS3 Somehow I suspect an obvious opportunity cost? https://t.co/EklKErsli0
Why are markets & subsidies are out of control. #Economics of scale of processed oats should not reach a stage where processed is cheaper than unprocessed. At best the price of scale for processed should come close to unprocessed, not go below #overshoot https://t.co/EklKErsT7y
@brockpierson Also - eat more whole. When we eat stuff without intact fiber, most calories are consumed by the mammalian cells and not our bacterial cells in the gut. 1 cal is not 1 cal. Keep it whole and plant based. https://t.co/EklKErsT7y
For that reason, processing matters. More intact fiber, more food for bacteria and less for the mammalian cells. In short
@ScepticalAnna Everyone should read this imo. It explains the difference between feeding our gut

@theproof Extracted powders like carb powders or protein powders or 100% extracted fat only are not needed or good https://t.co/EklKErsli0
@TamarHaspel Healthy weight loss requires two words coming together: Intact fiber https://t.co/EklKErsli0
@PlantChompers @ScepticalDoctor What is wrong with iron in real food? Also, why have they destroyed the oats? Do you know? https://t.co/EklKErsli0
@WardWriting High in intact fiber. Meat products and extracted nutrients like sugar, protein powder, dairy products or oil lack intact fiber. https://t.co/EklKErsli0
@Neonomide @ScepticalDoctor We lose health when we reduce particle size. When we extract, even more so. Olive oil is healthier than butter (less SF) but not healtheir than whole olives. Same with walnut oils vs whole walnuts. One doesn't need to make this ideological about brigades? https://t.co/EklKErsli0
@ScepticalDoctor @Alan_Watson_ @ggkuhnle Just the particle size can have an impact but when we isolate single nutrients
@jeffreyboadi_ The oats and seeds all have good protein? The frutis too. Just add more real foods to get more protein? But careful - particle size matters if one is diabetic as unnaturally small particles feed the gut less and host cells more. https://t.co/EklKErsli0
@ScepticalDoctor Reminder: Just the process of turning whole food into powders is bad? https://t.co/EklKErsli0
@waiterich Not sure we should call these "food". More like a recreational drug given their particle size? https://t.co/EklKErsli0
@TamarHaspel All animals have evolved for whole foods by definition. The less we process, the healthier our food is. Just changing the particle size of oats while keeping everything else equal will cost us health wise. https://t.co/EklKErsli0
@ScepticalDoctor @PlomeekSoup Adding some berries and soy milk to some oatmeal is rather fast too? It improves health rather than destroying it? Particle size matters however. https://t.co/EklKErsli0
@Nutradvance Reducing particle size feeds the human hosts cells more and the gut microbiome less. It's not a healthy step. https://t.co/EklKErsT7y
@saulohidalgo22 @ScepticalDoctor Are you saying we need a study to show if processing foods is bad compared to eating them whole? 1 week eating nut oil only compared to 1 week eating whole nuts only? Do we... really need this, or is it obvious and clear somehow? https://t.co/EklKErsli0
@mario_kratz Thanks for this good
@Alan_Watson_ @AnnieLeymarie @ScepticalDoctor Not what I mean. On paper we can consume the same nutrients with different health outcomes. Eg https://t.co/EklKErsT7y
@ScepticalDoctor A large potato has 8g intact fiber. I cannot find info about the bar but it will no be intact I assume but powdered. https://t.co/EklKEraJTq
@ScepticalDoctor https://t.co/EklKErsT7y
@ScepticalDoctor Isolated anything is not healthy compared to whole foods. Also protein and fat. We should try and eat at least half of our calories from whole intact plants? Note: No need to isolate to decrease health. Merely pulverizing plants costs us. https://t.co/EklKErsT7y
@ScepticalDoctor We want intact fiber & phytochemicals. If cell structure is destroyed, we feed our host cells and not our bacteria cells. This leads to low SCFA and higher GI. Foods low in fiber: - Animal products - Sugar powders - Grain powders - Protein powders - Oils https://t.co/EklKEraJTq
@hezy1a @ScepticalDoctor @sraosha One has to eat a lot of processed food (powders & oils) or meat to stay at 23-25 g/d of fiber. Processed fiber (not intact) and meat doesn't feed our bacteria cells (90%) but our host cells (10%). This leads to low SCFA and metabolic issues. E.g. https://t.co/EklKEraJTq
@DBelardoMD Interesting study regarding the difference of the whole plants vs plant powder. https://t.co/EklKErsli0
@ScepticalDoctor Since we do not want to exclude ANY plant groups, please self test within groups only? Whole oat berries vs oat powder https://t.co/EklKErsli0
@MacroFour @NutritionMadeS3 @ArkhamFantasy @FeliceJacka I cannot follow again. What does 'adding fiber' mean and come from? When I think of fiber, I only consider whole plants by definition. Processed fiber is NOT the fiber we are discussing. Intact fiber from whole plants is what we want. E.g. https://t.co/EklKErsli0
@ScepticalDoctor Why are whole peanuts healthy, but not processed? https://t.co/uDMmwLSgP7 Why are whole oats better than processed oats? https://t.co/EklKErsli0 Does that mean that we should never eat peanut butter? No. But we should be aware of it?
@timspector It's the level of processing that determines how many calories we consume for our host cells vs our bacteria cell? https://t.co/EklKErsli0
@NutritionMadeS3 Are processed oats as healthy as whole oats? https://t.co/EklKErsli0
@MichaelAlbertMD @JohnSpeakman4 Even for humans, whole is better than processed. Whole beets are better than sugar Wheat berries better than powder Whole peas better than powder Whole nuts better than oil Meat isn't healthy to start with but process it and it gets even worse too. https://t.co/EklKErsli0

@ScepticalDoctor @Maclagan_was_OK Level of processing counts. Brown rice has more fiber than white and is hence better for weight loss? Particle size of oats determines hunger and later weight? https://t.co/EklKErsli0
