Haven’t been able to independently corroborate this yet, but my daughter’s doctor told her that sugar suppresses the immune system for 72 hours.
Sugar causes AIDS!
J/K, but I'd like to know what the doctor meant by that, since if it's true, nobody in the US would have a functional immune system.
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.
