3. Sugar interferes with immune function.
Research on human subjects is scant, but animal studies have shown that sugar suppresses immune response5. More research is needed to understand the exact mechanisms; however, we do know that bacteria and yeast feed on sugar and that, when these organisms get out of balance in the body, infections and illness are more likely.
4. A high-sugar diet often results in chromium deficiency.
It’s sort of a catch-22. If you consume a lot of sugar and other refined carbohydrates, you probably don’t get enough of the trace mineral chromium, and one of chromium’s main functions is to help regulate blood sugar. Scientists estimate that 90 percent of Americans don’t get enough chromium. Chromium is found in a variety of animal foods, seafood and plant foods. Refining starches and other carbohydrates rob these foods of their chromium supplies.
