Glance at Foods Releases Insulin by Tanya Zilberter, PhD  Related articles: Before you choose a low carb diet Exercise and Low Carb Ketosis: Mystery or Misconception?
Look at this chart:  What you see here, are levels of glucose in the intestine where it arrives after you swallow carbohydrate-containing meal and in the blood where it gets presumably due to absorption of the swallowed glucose from the intestine. HOWEVER! Look closely at the bar indicating �eat� � glucose level in the intestine rises only after about 3 minutes after meal while glucose level in the blood rises sharply almost immediately, well before glucose can really be absorbed into the blood. Why? In 1974, Drs. Fischer, Hommel, Fiedler, and Bibergeil published an article titled "Reflex mechanism on insulin secretion," that now is considered classical work on insulin regulation. It's been followed by research data showing the details of insulin secretion time course. The insulin level rises already in the first minute after the start of a carbohydrate-rich meal, whereas the glucose level begins to increase only in the third minute. This early rise in insulin level is observed also when either carbohydrate-free food or even "food" without any caloric value is offered. The phenomenon is now well-researched under the name "cephalic phase of insulin release" though it is amazing how little it influenced the art and science of dietetics. FOOD INTAKE is considered as the primary cause of insulin secretion. In this view, carbohydrate-containing foods are absorbed into the circulation and stimulate the pancreatic beta-cells to secrete insulin. However, careful analysis of the time course of insulin secretion during carbohydrate ingestion has shown that insulin secretion can start even before glucose is actually absorbed. This so-called early insulin response is elicited by stimulation not only of taste buds but also through sight and smell of the food or even by meal anticipation. Artificial Sweeteners Are Not the Answer Sweet taste - even from artificial sweeteners - causes an increase in calories coming from fat and protein. No surprise considering what we've learned today. Sweet taste, even coming with artificial sweetener, raises glucose concentration in the blood before the food has a chance to be digested. Why? Because your body knows that eventually, it will have all the carbs you've swallowed and it doesn't wait until it that happens. When the sweet food is real, the carbohydrates eventually get into the blood. And if they're not? Well, nature never counted on us inventing artificial sweeteners. Being fooled, your body reacts rather vindictively: it forces you to want more sweet food plus eat more next time, no matter what food you agree to have. So, you'd be better off without artificial sweeteners. There are other tasty foods you can have on a low-carb diet. Some Clinical Data on Fats:
