Does sugar really lower your immune system, and if so, why???

Answer 1

I was surprised to find out that it actually does!

"Excess sugar depresses immunity. Studies have shown that downing 75 to 100 grams of a sugar solution (about 20 teaspoons of sugar, or the amount that is contained in two average 12-ounce sodas) can suppress the body's immune responses. Simple sugars, including glucose, table sugar, fructose, and honey caused a fifty- percent drop in the ability of white blood cells to engulf bacteria. In contrast, ingesting a complex carbohydrate solution (starch) did not lower the ability of these white blood cells to engulf bacteria. The immune suppression was most noticeable two hours post-ingestion, but the effect was still evident five hours after ingestion. This research has practical implications, especially for teens and college students who tend to overdose on sodas containing caffeine and sugar while studying for exams or during periods of stress. Stress also suppresses immunity, so these sugar-users are setting themselves up to get sick at a time when they need to be well."

Sorry about the paste, but I didn't think I could paraphrase effectively.
