Food Matrices: Protein & Fat Ameliorate Glucose Spikes After Standardized Glucose Load | Plus: Timing Matters if You Want to Turn Regular into Resistant Starch

Image
This is what it's all about. Real food does not come in form of "macros". It comes in form of complex food matrices that determine its effect on one's health - including one's glycemic health. You will probably remember that I have touched on a specific aspect of the effects of and interactions between different macronutrients in what scientists often refer to as "food matrices" on the glycemic response to standardized glucose loads in previous articles like the famous "True or False?" article that dealt with the question: "Will Adding Fat to A Carby Meal Lower the Insulin Response?" ( read it ). You don't remember this or any of the other articles? Well, in that case, I probably have to tell you again  that the mere fact that the postprandial glucose are lower does not mean that a certain food or combination of certain macronutrients would increase your insulin sensitivity (adding fat to a high carbohydrate meal certainly d...

Pre-Meal Protein Ingestion to Improve Glucose Tolerance: Insulin, GIP, GLP-1 - That's the Whey(!) it Works! Plus: Even Pure Glucose Can "Improve Your Insulin Tolerance"

Image
Can a whey protein appetizer really undo the damage of greasy fast food? Probably not, but it's still interesting to see how it affects the postprandial glycemia. Insulin resistance is the #1 contributing factor to the obesity epidemic and despite the fact the solution is already out there ( read more about the necessary lifestyle modifications), it probably won't hurt to know if something as simple as having a high protein "appetizer" before a junky meal could improve blood glucose management even further, right? "Right, 'cause protein is always, good!" Ah, no... I guess the answer is a little more complex than that... Nevertheless, I still suspect that the results, Tina Akhavan and her colleagues from the University of Toronto present in their soon-to-be-published paper in the Journal of Nutritional Biochemistry will be of interest to you. The study results are interesting, to say the least... ... and that's not despite but rather becau...

Glycemic Load, the GI's Complex Brother, Turns Out to Be A Good Predictor of Postprandial GLP-1 and GIP Response

Image
What does the glycemic load tell you about these foods? Right, an apple a day keeps the doctor away, ice-cream makes a healthy sweet treat and apple juice is one of those purportedly healthy drinks that are not on iota better than coke. It may be partly due to the correlation of low GL and high micronutrient content that going by the glycemic load is not the worst way to pick quality foods. After taking one week off, the SuppVersity Science Round Up is back today. As usual the show will kick off at 1PM EST (update: download podcast ) and I cannot complain about not having enough stuff to talk about. So here is a sneak peak on the news line-up for today: insulin in the brain - how it's keeping you lean breast cancer - protective & useless micronutrients prenatal caffeine - negative effects on male offspring mouth rinsing - caffeine & carbs, both work ashwaganda - Lance's new dope? betaine - the ergogenic w/ anti-NASH effect There is more - as usual, so do...

On Short Notice: Testosterone - 12% Drop /W 75g Glucose? Fat Loss - Adzuki, Leucine + B6 or HiMaize? Thyroid - T3↓ + rT3↑, Is Blood Sugar to Blame and Can TUDCA Help? +More!

Image 1: It's quite funny, I am piling up so many of these interesting mini-news that I actually had to drop a few or postpone them to next week to keep the size of this post manageable without a direct brain transmission device like the one you see in this picture ;-) " On short notice " is the name of the new 'saturdaily' SuppVersity column and therefore I will try to make it short: After all, you've got a hell lot to learn today and unless you have just crawled out from beneath your sheets, your testestorone levels and with it your cognitive abilities will aready have declined - that's not you? Well I guess you have the hubris of a boxer , then, or you did simply sleep so little that even your increased energy consumption could not make up for the memory dysfuction that's been brought about by the sleep deficit. Let's just hope that your cell mass is at least so high that your basal energy expenditure is sufficient to burn those serotoner...

Whey More Insulinogenic Than White Bread: Insulin Spike is Mediated by GIP Secretion in the Gut & Effect of EAAs on the Pancreas + Why Whey is Still the Better Choice

Image
Image 1: Peter Czerwinski, aka Furious Pete , certainly did not care about the pro-insulinogenic effects of whey, when he ate 900g of it within 3:30min, click here to watch his record ( Furios Pete, 2010 ) Among muscle heads and physical culturists, alike, whey protein has become almost synonymous with building slabs of lean muscle.What many of the protein fans - especially the low carbers - tend to overlook or ignore, though, are the pro-insulinogenic effects of whey protein , in general, and purified whey protein isolates and hydrosolates, in particlar, which do not just augment the insulin release in response to carbohydrate ingestion (Morifuji. 2010), but exert a decent increase in pancreatic insulin release in and out of themselves (Claessens. 2009). Further evidence on the hitherto not yet fully understood mechanism behind the whey induced increase in insulin comes from a recently published paper by Albert Salehi and his colleagues from the Lund University in Sweden, the ...
