"They have never done studies in humans beyond a few weeks and effects would likely show up over decades." In fact, the FDA, as a condition of approval, is requiring P & G to continue studies on olestra consumption.Harvey Anderson, a professor of nutritional sciences at the University of Toronto who has worked as a P & G consultant, takes a more benign view of olestra.
