Glycemic index dietary fiber

Dietary fiber Can slow absorption of refined carbohydrates and lower glycemic index of foods, resulting in reduced effects of diabetes due to lower availability of glucose Preuss (2009)... 

A recent commentary in the Lancet suggests that there are (Katan, 1999). In one case study, the diets of over 65,000 women were examined over a six-year period (Herman, 1997). Results from these studies showed that women who consumed a low-fiber diet along with plenty of soft drinks were two and a half times more likely to get diabetes than those who consumed a high-fiber diet with very few soft drinks. This study showed that sugar was not the only culprit. Other dietary culprits included white bread, white rice, and potatoes. This finding led to the controversial glycemic index (GI) concept, which was developed as a tool to help people monitor and stabilize their blood sugar level. 

Dry masa flours are currently being supplemented with common bean (Phaseolus vulgaris) and cactus (Opuntia spp.) flour. Both beans and cactus flours are rich sources of dietary fiber. The green-colored cactus supplemented tortillas, rich in both soluble and insoluble dietary fiber, are mainly consumed by diabetic and hyper-cholesterolemic people to lower glycemic index and blood cholesterol. 

Whole wheat bakery products are produced in order to provide higher amounts of dietary fiber with proven health benefits. A comparison between white pan and whole breads indicates that the first contains about one-third of the dietary fiber found in whole wheat pan bread (Table 17.8). The consumption of whole grain breads also slightly lowers energy density and it has a lower glycemic index, improving gastroin-...
