Does Your Multivitamin Contain Copper?

Older people whose diets are heavy in copper, saturated fats and trans fats experienced a faster rate of mental decline.
A six-year study of more than 3,700 people aged 65 or older showed that those who consumed at least 1.6 milligrams of copper a day, along with high levels of saturated and trans fats, added almost 20 years to their ages in terms of mental decline. The U.S. daily recommended intake of copper is 0.9 milligrams.
Too much copper in the blood could block the body's ability to destroy the proteins that form the plaques found in the brains of Alzheimer's patients. Copper has been found at high levels in the blood of Alzheimer's patients.
Many of those in the study with high copper levels took multivitamins containing the mineral.
