Basically, the main solution provided by Dr. David is founded on a simple and effective white starch, also called dietary resistant starch (RS). Resistance starch is found in many natural foods which we consume regularly. It is a form of carbohydrate that is not readily digested in the stomach but passes into the gut and acts like a type of soluble dietary fiber. From the gut it travels into the large intestine where it is digested by millions of bacteria and turned into a form of fatty acid.
Currently, research has shown that resistance starch is present in foods like raw potatoes and unripe bananas. It can also be found in some legumes, grains and seeds. But resistance starch is also formed when certain starchy foods such as rice and potatoes are cooked and then left to cool. During the cooling process, some of the starch is converted to resistance starch through a process known as retro gradation.
