7.Zinc
Many American seniors don’t get enough of this underappreciated micronutrient. It helps your sense of smell and taste, and fights infections and inflammation — all important jobs in older bodies. Zinc also may protect your vision. Oysters are far and away the best source of this mineral. Otherwise, you can get it from beef, crab, and fortified breakfast cereals.
8.Selenium
It protects your cells from damage and infection, and keeps your thyroid working the right way. Selenium also can keep your muscles strong, and may help prevent age-linked illnesses like dementia, some types of cancer, and thyroid disease. Just one or two Brazil nuts a day should be enough. Don’t overdo it. Too much selenium can make your hair fall out and turn your nails brittle.
