Dietary Effects upon Immunity

According to RK Chandra as quoted from an introduction to the Immune System, which appeared in the American Journal of Clinical Nutrition, “Nutrition is a critical determinant of immune responses and malnutrition is the most common cause of immunodeficiency worldwide.”

Work with both animals and humans consistently shows that variable Immunodeficiency’s can arise as a result of various forms of malnutrition. It is important to realize that there are many forms of malnutrition, not just the starving populations of Third World countries.

Protein deficiency in industrialized nations such as the United States and the European countries, is often widespread and severe.

Protein calorie malnutrition causes many complex nutrient deficiencies which can lead to immune suppression.

For instance, Thymus dependent T cells are reduced and their capacity to generate mediators such as Gamma Interferon and Interleukin 2 is greatly decreased.

Researchers studying the relationship between the Immune System and diet consistently find a direct link. The importance of diet in multiple aspects of the immune response is inescapable.

Even though there have been only a few clinical trials in this area so far, the modulation of the immune response through manipulating dietary intake will surely become one of the leading modalities in the management of immune related disorders in the future.

Because protein is of vital importance in the integrity of all human cells, a deficiency of protein is probably one of the greatest factors in Immunosuppression. There are several reasons why protein deficiency may exist in humans.

Firstly, and most obviously, is a lack of protein in the diet. In so called civilized’ countries, we assume that no one is protein deficient, but surveys of dietary habits done by many institutions, including our own, show that indeed many millions of people do not eat adequate amounts of high quality complete protein.
Another factor in protein deficiency is lack of absorption. As we age, protein foods become more and more difficult to digest and assimilate at the cellular level. This is due to a reduction in the protein digestive substance called Hydrochloric Acid, naturally present in the stomach.
As we age Hydrochloric Acid is diminished through the over consumption of dead and lifeless foods.
For this reason, the first recommendation for building and maintaining a strong, healthy Immune System is to ensure that not only adequate protein is being consumed but that the digestion of that protein is complete. We do that by adding a multi purpose digestive enzyme product that contains Betaine Hydrochloride to each meal.
What about the role of fats in the diet? Fats are among the most commonly misunderstood foods in the diet. A low fat diet is not generally healthy for people except under certain very specific circumstances. The low fat diet craze of the past twenty five years has produced a variety of health challenges as well as premature aging.

Conversely, a high fat diet is not necessarily healthy either. More important than quantity, is the source of the fat in the diet.

Some fats are not only less beneficial than others but, in some cases, contribute to a variety of disease processes. Polyunsaturated Fats not only produce the Free Radicals directly responsible for Atherosclerosis, but excessive, fatty acids from these oils have been established in Immunodepression.

By reducing fats, specifically Polyunsaturated Fats, we can enhance the performance of the natural killer cell activity.
