In general terms, putting RS back into the diet offers enhanced digestive health, improves the function of the intestines, helps control blood sugar fluctuations, and promotes satiety (the feeling of having eaten enough).
Specific benefits are:
Prebiotic effect / Bowel Health
Foods high in resistant starch can improve bowel function and populations consuming traditional diets high in RS appear to be at low risk of several serious bowel diseases. There is experimental evidence which supports a protective role for RS in these diseases. Although as yet there is no direct proof in humans, recent animal studies have shown that resistant starch can prevent genetic damage induced by eating a high protein and high fat diet of cooked meat or casein. Genetic damage is a prerequisite for cancer, in this case, of the colon.
Resistant starch-rich foods help control blood sugar levels, avoid sugar highs after a meal and help in the longer term regulation of blood glucose.
The consumption of RS allows an increase in the amount of calcium & magnesium absorption in the large bowel through short chain fatty acid production in the intestinal tract, due to prebiotic fermentation.
It has Digestive tolerance
Intakes of RS up to 40 grams/person/day have been reported to have no negative digestive effects.
