Fiber – the unrecognized macronutrient of evolution
Richard Aiken MD, PhD
Fiber, although not considered a macronutrient, has a RDA of 25 – 38 gm/ day according to the National Academy of Sciences Institute of Medicine’s Food and Nutrition Board and is only available from plants. We know that the most healthful diet is one that is high in fiber and low in rapidly digested carbohydrates. This regimen is referred to as a low-glycemic diet because it helps keep our blood glucose at optimum levels. Wild fruits and vegetables are the original low-glycemic foods.
