The total sugar content normally present in your bloodstream is approximately one teaspoon. Consuming a can of soda or bowl of ice cream (e.g., average 12 teaspoons sugar) causes the pancreas to work hard excreting insulin, and the stress is not good for the immune system. (Kaiser, Jon D., MD. Immune Power. p 28-29. NY: St. Martin’s Press, 1993.)

The most common response to hypoglycemia (low levels of blood sugar) is to eat another sugar snack, although this will drive the blood sugar up quickly again. It takes the brain another 45-75 minutes to regain normal intellectual function after the blood sugar returns to normal. (Nedley, Neil, M.D. Proof Positive. p 273-275. OK:Nedley, 1998, 1999.)

Caffeine can increase the amount of sugar in the bloodstream and provide a temporary “lift.” The rush of insulin, however, causes the sugar level to subsequently fall below normal causing extreme fatigue. It may be hours before the body’s chemistry returns to normal. (Appleton, Nancy, PhD. Lick the Sugar Habit. p 116-118. NY: Avery Penguin Putnam, 1996.)

A quick dose of sugar causes blood sugar to rise rapidly. To compensate, the body releases insulin, forcing the blood sugar level to plummet. The end result? Another sugar attack. Common side effects include nervousness, crankiness, headaches, and bad dreams. (Padus, Emrika, et al. The Complete Guide to Your Emotions & Your Health. p 371. PA: Rodale Press, 1986.)

Each food has its own distinctive abilities to raise blood sugar (e.g., dates spike rapidly, dried apricots or raw/cooked/canned carrots do not). Eating white potatoes or regular white bread is just like eating candy as far as your body knows. (Carper, Jean. Your Miracle Brain. p 123-126. NY: HarperCollins Publishers, Inc., 2000.)

Sugar can be toxic. Inflammatory chemicals spread throughout the brain and body following a rise in blood sugar. They produce enzymes that break down collagen. This can cause wrinkles in the skin and damage to the brain. (Perricone, Nicholas, MD. The Perricone Promise. p 12-13. NY:Warner Books, 2004.)
