Fat is needed in the body to provide a consistent, long burning source of fuel - so we aren't hungry all day. Fat is converted into phospholipids which make up cell membranes. Healthy cell membranes are necessary for every function in the body to operate successfully. Fats are necessary for healthy liver function and building healthy bile. Bile is vital in fat digestion and in elimination and detoxification.
Fats are also required for absorption of fat soluble vitamins: A, D, E, K. Vitamin A is critical for sexual reproduction, cell division, vision, immune system function, bone remodeling, tooth enamel formation, and skin health. Vitamin D is a vitamin and a hormone made in the skin from cholesterol. Vitamin E is required for reproduction, for cardiovascular health and as an antioxidant. Vitamin K is required for blood clotting and maintaining bone density.
Fats are required to metabolize proteins effectively. Fats serve as a protective lining for the organs of the body, protect joints, slow absorption of food for proper energy regulation and help us maintain stamina. Fats help with hydration and sugar balance. Fats are essential in protecting against metabolic syndrome, obesity and diabetes by reducing insulin surges and reducing cravings for sugar and carbs. Fats also help protect against cardiovascular disease.
