Things Your Body Needs as You Age

Potassium plays a part in almost everything inside your body, including your heart, kidneys, muscles, and nerves. It also may help protect against stroke, high blood pressure, and osteoporosis. Many Americans don’t get enough. Dried apricots, bananas, spinach, milk, and yogurt are good sources. Ask your doctor before you take supplements. They can interfere with medications for high blood pressure, migraine, and other conditions.

This natural form of vitamin B9 is in leafy greens, nuts, beans, and other foods. Pregnant women take a lab-made form of vitamin B9 called folic acid to help prevent birth defects. Folate helps with cell growth and may protect against stroke and certain cancers. Most Americans get enough. Folate found in foods is safe. But too much folic acid from supplements or fortified foods can raise your odds of having colon cancer or nerve damage.

You probably know fiber is good for you. But did you know it’s even more important as you age? Fiber helps protect against strokes, helps you poop more regularly, and lowers your cholesterol and blood sugar — big benefits in older bodies. Women over 50 should get at least 21 grams a day, while men need 30 grams, but most people don’t get that much. That’s equal to about 6-8 servings of whole grains, or 8-10 servings of vegetables.

Whether it’s vitamins, minerals, or fiber, it’s best to get them from foods instead of pills. But that can be a challenge for some older Americans, especially if you don’t eat a balanced diet. You’re most likely to lack vitamin D, potassium, calcium, or dietary fiber. If you think you need more than you can get from food, talk to your doctor about supplements that will be safe with your meds, diet, and health.

There’s little, if any, proof that multivitamins benefit seniors who are otherwise healthy. The U.S. Preventive Services Task Force recommends against daily multivitamins to ward off cancer or heart disease. Multivitamins marketed at seniors may be tailored with higher doses of vitamins D or B12 or less iron. But unless you have a poor appetite or have conditions that keep you from eating a healthy diet, you probably don’t need them.
