Fat Functions To Promote Good Health

Well until I “fell” into a low carbohydrate lifestyle, I would have told you that fat functions to make you fat and that too much fat will negatively impact health leading to heart disease, cancer, diabetes… and in the end result in an early death.
Now that my focus on attaining health and weight goals are through nourishing the body, I sing a much different tune. Here are a few of the benefits of eating healthy natural fats. I found this list at, http://www.helpguide.org/life/healthy_diet_fats.htm and appreciated everything they had to say until I read that the suggested range of fat consumption was 20-35% of total calories.
Brain – Fats compose 60% of the brain and are essential to brain function, including learning abilities, memory retention and moods. Fats are especially important for pregnant women, since they are integral to fetal brain development.
Cells – Fatty acids help your cells stay moveable and flexible, as well as being responsible for building cell membranes.
Heart – 60% of our heart’s energy comes from burning fats. Specific fats are also used to help keep the heart beating in a regular rhythm.
Nerves – Fats compose the material that insulates and protects the nerves, isolating electrical impulses and speeding their transmission.
Lungs – Lung surfactant, which requires a high concentration of saturated fats, enables the lungs to work and keeps them from collapsing.
Eyes – Fats are essential to eye function.
Digestion – Fats in a meal slow down the digestion process so the body has more time to absorb nutrients, and help provide a constant level of energy and keeps the body satiated for longer periods of time. Fat-soluble vitamins (A, D, E, and K) can only be absorbed if fat is present.
Organs – Fats cushion and protect your internal organs.
Immune System – Fats ease inflammation, helping your metabolism and immune system stay healthy and functioning
You see in my mind, if fat benefits the body in all the ways mentioned above, why not feed your body more fat to support all the body functions that are mentioned above?
