RS Fibre

- Blend of resistant starches and other fibers
RS Fiber contains two forms of type II resistant starch: green banana flour and powdered potato starch. Resistant starches (RA) are defined as starches resistant to human enzymatic digestion in the upper gastrointestinal tract; they are metabolized to short-chain fatty acids by bacteria in the lower gastrointestinal tract; they therefore do not contribute to the increase in blood sugar levels. Common starches differ from ARs in that they are broken down into glucose molecules in the upper digestive tract by enzymes in the mouth, pancreas, and brush border of the small intestine. This glucose is rapidly absorbed, resulting in a rapid, and sometimes drastic, increase in blood glucose. The RS Fiber blend provides 4g of resistant starches combined with 3g of regular starches, thus not allowing a significant increase in blood sugar levels.
In the United States, the average intake of total fiber is estimated at 15 g/day and the daily consumption of AR at 5 g5. This intake is well below the current recommended daily allowance (RDA) which is 25-30 g/day and significantly lower than the 50 to 100 g of fiber consumed daily for a large part of human evolution18. The average diet in the United States is considered deficient in fiber, an important nutritional element for supporting good health. Raw starches, found in root vegetables and fruits, constitute an important component of the evolutionary human diet. This may therefore explain why the human gastrointestinal tract and the body's glucoregulation mechanisms are not adapted to properly metabolize large quantities of refined and concentrated sugars and starches and benefit more from starches resistant to digestion.
