Most people look at what fats can do for the body and how important this category is for an athlete. Inside the body, it will depend on our fat to benefit the body. “Fat, or adipose tissue, functions as an insulator to preserve body heat and protect the body's organs” (Iowa State University), without fats in our bodies athletes could run the risk of causing injury to their organs or other parts in their body during the competition. In order for the athlete to perform at his best, it is important to ensure that the organs are protected and that body heat is well stable so that the athlete does not feel muscle cramps or fatigue during the competition. “It is from dietary fats that we obtain EFAs (essential fatty acids) that cannot be produced by the body” (Guzmna). Essential fatty acids are fatty acids that must be ingested because the body needs them for good health but cannot produce them. “Fats are also important in building cell membranes, they are needed to make bile (which helps break down fats), cholesterol (a type of fat) is needed to make important hormones like testosterone, and fats give flavor to food." better and helps us feel fuller” (Guzman). When fasts are broken, they are divided into four different categories; Trans fats, saturated fats, polyunsaturated fats and monounsaturated fats. Trans fats are also known as hydrogenated fats and “increase the risk of coronary heart disease by increasing bad LDL cholesterol and decreasing good HDL cholesterol” (Guzman). Athletes must be careful what they consume when considering fats as a source of energy, there are generally more bad fats than good fats and if an athlete has to consume too many of the wrong fats they can run the risk of a heart attack.
