Your immune system is a complex organization of organs, glands, fluids, and specialized cells. These act together in a wonderfully orchestrated manner to protect you from invading organisms and from the normal hazards of metabolism.
The food you eat can affect your immune function. Refined sugars, for example, can decrease the ability of your white blood cells to destroy invading bacteria or viruses. On the other hand, betacarotene and other carotenoid compounds stimulate the thymus gland to produce thymosin. Thymosin along with zinc and arginine encourages production of more active and more energetic T-cells. These T-cells, as well as doing other things, produce interferon, a substance that stimulates protein production in cell walls, making your cells less vulnerable to the intrusion of viruses.
Neutrophils are white blood cells that engulf bacteria by enveloping them and then digests them. Their ability to perform depends upon the fluidity of their cell membrane. Fluidity is a function of the fatty acid balance you eat. You particularly need the correct balance of Omega-3 and Omega-6 fatty acids, as found in premium AFA algae (a.k.a. Alpha Sun).
All white blood cells are dependent upon various enzyme systems. Enzymes must have the right vitamins and minerals present in the right proportion before they can carry out their functions. Unlike laboratory formulations, the vitamins and minerals found in raw foods, such as premium AFA algae (Alpha Sun), are chelated in live enzymes and enzyme systems. Thus your body can easily assimilate and easily make use of those nutrients. This explains why refined sugars diminish your immune function. They rob you of vitamins and minerals just to be dealt with in the digestive tract and to be dealt with once they reach your cells. This uses supplies that would otherwise have been available for your immune system.
Premium AFA algae (Alpha Sun) has a wealth of nutrients that are bound up in living systems, easily accessible to the human organism. Your body can use those nutrients for many different functions including your immune system.
