This book examines the ways that fiber & antioxidants can counteract the effects of the fat in our diets. This means that we can now have greater freedom in making food choices. The information comes from medical journals. The author explains how he utilized the information to help himself maintain slimness & healthy cholesterol without having to follow a severely restrictive diet. Here are just two of the many discussed concepts: (1) The fat in our diets produces fatty acids that are converted to cholesterol-related acids that can clog arteries & raise cholesterol levels. Fiber counteracts that effect by removing cholesterol-related acids from our bodies before they can clog arteries, thus promoting healthy cholesterol levels & reducing our risk of heart disease. (2) The excess calories in fatty foods can cause us to gain weight, thus increasing our risk of obesity. Fiber counteracts that effect by reducing our caloric absorption, thus making it harder for us to gain weight & reducing our risk of obesity.
