Lipids are fats and fatty substances that serve as a source of fuel in the body and are important to cell structure. Lipid consists of carbon, hydrogen, and oxygen. Lipids are important because they limit water and water soluble substances from passing through the membrane, which keeps the contents of the cell separated from the outside environment (Funk& Wagnalls New World Encyclopedia, 2014). Lipids consists of triglycerides, phospholipids, steroids, eicosanoids, and the simplest; fatty acids.

Fatty acids are the group of lipids that are used to synthesize triglycerides and phospholipids. The body can produce some essential fatty acids (EFA’s), but most has to be gained by food intake. Fatty acids can assist in the increase of exercise and performance ability. There are two fatty acids that are essential for our health: Omega-3 and Omega-6 fatty acids. The benefits of Omega-3 are that through proper nutrition, become protection and prevention for the body and is beneficial for physical and mental health. Omega-6 fatty acids are essential for health but only in moderation. There are three benefits of Omega-6 acids; important in cell growth which helps brain and muscle development, helps in the production of hormone messengers, and transmits nerve impulses ( Manea, Buldus, & Tache, 2014).

Another type of lipid is cholesterol. Cholesterol is a compound important in the production of sex hormones, steroids, cell membranes, and bile acids. Cholesterol is produced in the body and is in contained in foods that have animal...
