Society has tried the low-fat nonsense approach to diet and found it a dismal failure. There are many dangers associated with a low-fat diet. Now in a small study of women, a diet low in fat and high in fruits and vegetables caused an increase in the plasma levels of oxidized LDL cholesterol, the "bad" cholesterol. Lower fat diets may be beneficial for some, especially those with carbohydrate nutritional types, but all of us need some beneficial fats in our diet to stay healthy and fat phobia and exclusion of all fats is a prescription for disaster.
