Sugar robs nutrients from the body needed for its metabolism, so nutrient deficiencies such as osteoporosis, anemia, and immune deficiencies are all influenced by sugar consumption. The immune system itself is affected by sugar as it inhibits the release of growth hormones when it raises insulin levels. It also utilizes its white blood cells to clean up waste products left behind by sugar, instead of having them fighting bacteria and disease, as is their main role. Sugar, and its ability to cause inflammation is involved in conditions such as dermatitis, hyperactivity, indigestion, and depression. Sugar can play havoc with the digestive system, weakening it, and not allowing nutrients to be assimilated properly. Sugar ferments and interferes with digestive health, often causing gas and bloating.
