The remarkable impact of the structure of food beyond nutritional content or composition. “Food structure,” not just nutrient composition, may be “critical for optimal health.” It should come as no surprise that cornflakes and Rice Krispies cause a much greater spike in blood sugars than rice or corn-on-the-cob; but it’s not just the added sugar. “Even with identical [ingredients], food structure can make a major difference…” For example, if you compare the absorption of fat from peanuts, compared to the exact same number of peanuts ground into peanut butter, you flush more than twice the amount of fat down the toilet when you eat the peanuts themselves, since no matter how well you chew, small bits of peanuts trap some of that oil makes it down to your colon. And, “the physical form of food” not only alters fat absorption, but carbohydrate absorption as well. For example, rolled oats have a significantly lower glycemic index than instant oatmeal, which is just oats, but in thinner flakes. And, oat flakes cause lower blood sugar and insulin spikes than powdered oats. Same single ingredient: oats, but in different forms can have different effects….
