Fats, or lipids, are a class of foods that have gained much attention over the last several years. The general assumption is that all fats are bad or unhealthy, but this is not true. Fats from the right sources are an integral part of a healthy diet. Fats contribute a significant amount of energy to our food. In the appropriate quantities and types, fats will provide much of the energy needed to get us through the day. Additionally, they support and cushion our internal organs, protecting them from harm. Fats are also responsible for regulating body temperature, insulating us from the cold. Finally, they are necessary for the proper absorption of some integral vitamins, namely A, D, E and K.
