Sugar impacts the immune system by suppressing phagocytes and can occur from: (all types of sugar), glucose, fructose, honey, maple sugar, corn syrup, dextrose, dextrin, rice syrup, barley malt, and fruit juice concentrates. (Summary article: Appleton, Nancy, PhD.Lick the Sugar Habit, Sugar Counter. NY: Avery Penguin Putnam, 2001. Lick the Sugar Habit. NY: Avery Penguin Putnam, 1996.)

Studies: 14 bacteria are engulfed by each white blood cell if participant ingested no sugar, with progressive declines in the number of bacteria engulfed as sugar consumption increased. Ingesting 24 teaspoons of sugar (equivalent of two cans of soda) produced a 92% decrease in white blood cell’s ability to engulf bacteria. (Kaiser, Jon D., MD. Immune Power. p 28-30. NY:St. Martin’s Press, 1993.)

Study: Sugar decreases the ability of white blood cells to immobilize bacteria. After 100 grams of glucose was injected into an animal, the ability of white blood cells to ingest bacteria fell from 14 bacteria to 1. The equivalent of a human eating 18 teaspoons of sugar at one time resulted in an 85% decrease in the Phagocytic Index (e.g., one slice of cherry/berry pie or one 4-oz slice of iced chocolate cake averages 10 teaspoons of sugar).

Your immune system is the most sensitive system of your body to your energy level. For energy, completely avoid white sugar, alcohol, cigarettes, white flour, etc. (Kaiser, Jon D., MD. Immune Power. p 20-22. NY: St. Martin’s Press, 1993.)

The negative dietary habits that cause the most problems to the immune system (weaken it) are the excessive consumption of sugar, caffeine, and alcohol (especially if combined with skipping breakfast and an inadequate protein intake). (Kaiser, Jon D., MD. Immune Power. p 28-30. NY: St. Martin’s Press, 1993.)

Refined sugars, chocolate, candy, syrups, and all artificial sweets are anti-immunity foods. Avoid them to minimize your risk of diet-induced cancer and to promote maximum immune readiness. (Weiner, Michael A., PhD. Maximum Immunity. p 87. MA: Houghton Mifflin Company, 1986.)

White blood cells, including T-helper cells, are adversely affected by excessive amounts of sugar in the bloodstream. Studies: the greatest effects occurred between one and two hours after a liquid sugar meal, but ability was depressed for up to 5 hours afterwards. (Jon D., MD. Immune Power. p 28-30. NY: St. Martin’s Press, 1993.)

If a person consumed no sugar for 12 hours, each white blood cell could destroy an average of fourteen bacteria. When 24 teaspoons of sugar were ingested (average amount in a medium piece of cheesecake or a milk shake) the white blood cells were so compromised they could only destroy an average of one bacterium each, a 92% reduction.
