is one of the biggest reasons that almost all Americans get sick.
The cell membrane controls everything that goes into and out of a cell. Making certain that only the right things go in and out of the cell is a critical and complex task that only can be accomplished when the cell membrane is constructed correctly. The membranes that surround each of the trillions of cells in your body are made mostly of fats and oils. Membranes constructed out of the wrong fats and oils do not function properly, which is a problem for most Americans. For example, diets with excessive amounts of saturated fats, which are rigid molecules, create rigid cell membranes that lack necessary elasticity. Catastrophic failures, such as ruptured blood vessels and torn muscles and tendons, can occur in tissues made from these rigid cells.
Cell membranes are made primarily of fatty molecules called phospholipids. Special kinds of oils called essential fatty acids (EFAs)âomega-3s and omega-6sâare used to create the phospholipids in cell membranes. These oils are essential because your body is unable to produce them; these oils must be obtained through diet. An overwhelming majority âsome estimate as much as 90 percentâof the U.S. population may be deficient in the correct assortment of essential fatty acids. When the correct raw materials are lacking, the body makes cell membranes out of whatever raw materials are available. These materials include the hydrogenated oils found in margarine, vegetable shortening, baked goods and breakfast cereals; the saturated fats from meat and dairy products; and the trans-fatty acids found in processed salad and cooking oils. Cell membranes built from these inappropriate fats and oils cause the membrane and the entire cell to malfunction.
For example, building a cell membrane from hydrogenated oils impairs the passage of oxygen into the cell, and oxygen-deficient cells become cancerous. None of us would build a house with cardboard walls. Why, then, do we build our cell membranesâour first line of defense against diseaseâout of junk materials like margarine, vegetable shortening and supermarket oils? Modern diets fail to supply adequate amounts of the correct essential fatty acids. I recommend supplementation with high-quality essential fatty acids and fish oils (see appendix C).
Weak and Rusty
To be healthy, cells must be supplied with adequate amounts of antioxidants. Cell membranes and the factories and powerhouses inside of cells can be damaged from oxidation via free radicals. Picture how oxidative damage (rust) would cause the Golden Gate Bridge to disintegrate were it not painted with a protective coating each year. Currently, our bodies are immersed in a sea of highly reactive chemicalsâ such as ozone in urban air and chlorine in tap waterâthat create oxidative damage to our bodies. You likely have heard reports about antioxidants (such as vitamins A, C and E) and how they protect us against free radical damage.
Free radicals damage our cells just like rust corrodes metal. Free radicals have unpaired electrons. Electrons, which travel in pairs, are charged particles orbiting around the nucleus of atoms. An unpaired electron aggressively seeks a mate, trying to âgrabâ an electron from something else, perhaps a molecule that is performing an important job in one of your cell membranes. Once the electron is grabbed, that molecule can no longer perform its job properly; furthermore, the molecule now becomes a free radical itself, aggressively seeking its own electron mate. The subsequent chain reaction can result in serious cellular damage commonly associated with aging and disease, unless the bodyâs tissues are rich with antioxidants that can stop hazardous chain reactions as soon as they begin.
Free radicals are naturally produced as we metabolize oxygen. Free-radical chain reactions are constantly being produced and stopped inside your body. Cells were
