Chromium

Functions of Chromium

• Works with insulin in the metabolism of sugar and stabilizes blood sugar levels.
• Cleans the arteries by reducing Cholesterol & Triglyceride levels.
• Helps transport amino acids to where the body needs them.
• Helps control the appetite.
• Medical research has shown that persons with low levels of Chromium in their bodies are more susceptible to having cancer and heart problems and becoming diabetic

Deficiency of Chromium

Glucose intolerance in diabetics; arteriosclerosis, heart disease, depressed growth, obesity, tiredness.

Recommended dietary allowance for Chromium

See Recommended dietary allowances for minerals.

Food sources of Chromium

Egg yolks, Molasses, Brewer's yeast, Beef, Hard Cheese, Liver, Fruit Juices, Whole Wheat bread.

Toxicity of Chromium

Toxic effects are limited primarily to industrial exposure to hexavalent chromium, which is much more toxic than the trivalent form. The acidity of the stomach promotes reduction of hexavalent chromium to the trivalent form. Most of the chromium absorbed from the gastrointestinal tract is trivalent.
