Ideas in this flowchart

• Recommended intake, functions, deficiency, and toxicity of chromium and fluoride
• Chromium
• Recommended intake: 25–35 mcg/day
• Chromium assists insulin in carbohydrate, lipid, and protein metabolism
• Chromium deficiency can cause abnormal glucose metabolism
• Malnourished children are at risk for chromium deficiency
• No UL has been determined for chromium
• Fluoride
• Sources include fluoridated water, foods prepared in fluoridated water, and seafood
• Recommended intake: 3–4 mg/day
• Fluoride is a component of mineralized bone
• Fluoride provides bone structure and microarchitecture and stimulates new bone growth
• Fluoride deficiency increases the risk of dental caries
• The risk is especially high among populations with nonfluoridated water
• Fluoride toxicity can cause fluorosis, mottled teeth, and kidney damage
• UL: 10 mg/day
