There are so many diets out there that most of us are confused about which one is right for us. Some of this is because there are so many "one size fits all" diets, such as the one recommended by the USDA in its food pyramid. In general there is a huge misconception that fats are bad and a lack of understanding that high fructose corn syrup and other sugars are dangerous. Some fats are essential for life and must be eaten in our diets because our body cannot make them.
