Dietary Sources Of Beneficial Chromium

Significant dietary sources of trivalent chromium are available in various food sources such as whole-grain products, high-bran breakfast cereals, egg yolks, coffee, nuts, green beans, broccoli, meat, Brewers' yeast, and selected brands of beer and wine. Chromium is also found in many mineral or multivitamin supplements. According to the National Research Council (NRC), the Estimated Safe and Adequate Daily Dietary Intake (ESADDI) for trivalent chromium is 50-200 ^g/day, corresponding to 0.833.33 ^g/kg/day for an adult weighing 60 kg [6]. The Food and Drug Administration (FDA) has selected a Reference Daily Intake (RDI) of 120 ^g/day for chromium. However, normal dietary intake of chromium for adults may be less than optimal. Recent reports demonstrate that the normal US adult chromium dietary intake is less than 50 ^g/day, resulting in approximately 0.4% chromium absorption. Results from one study indicated that daily chromium intakes for men and women in the US were 33 and 25 ^g, respectively [7]. Fortunately, trivalent chromium significantly influences bioavailability. At a dose of 1000 ^g/day absorption of chromium from chromium chloride (CrCl3) is ~0.4%, whereas that from chromium picolinate may be as high as 2.8%. Once absorbed, chromium is distributed widely in the body, with the highest levels being found in the kidney, liver, spleen, and bone [8].

Diabetes 2

Diabetes is a disease that affects the way your body uses food. Normally, your body converts sugars, starches and other foods into a form of sugar called glucose. Your body uses glucose for fuel. The cells receive the glucose through the bloodstream. They then use insulin a hormone made by the pancreas to absorb the glucose, convert it into energy, and either use it or store it for later use.
