CHICAGO -- Elderly people whose diets were rich in copper and heavy in saturated fats and trans fats risked faster mental decline that could be related to the onset of Alzheimer's disease, researchers said.
In the six-year study of more than 3,700 people age 65 or older, about 600 of the subjects consumed at least 1.6 milligrams of copper a day, along with foods heavy in saturated and trans fat. Many of those people added the equivalent of 19 years to their ages in terms of mental decline, according to the study.
While copper, zinc and iron are essential for brain development, too much copper in the bloodstream may block the body's ability to rid itself of proteins that form plaques found to clog the brains of Alzheimer's patients, study author Martha Clare Morris of Rush University Medical Center in Chicago found.
Copper, which has been found at higher levels in the blood of Alzheimer's patients, is normally consumed in animal organs like liver, and in shellfish, nuts, legumes, some fruits, potatoes and chocolate. Drinking water that travels through copper pipes can also contain copper. Many of those in the study with high copper levels got it primarily through multivitamins.
