If you feel run-down, lack of iron is probably not the cause. You can easily get enough of this key mineral in your diet.

Decades ago, advertising for the liquid vitamin and mineral supplement Geritol warned against "iron-poor, tired blood." It's a reference to the fact that red blood cells need iron to make hemoglobin, the molecule that grabs oxygen and transports it around the body.

This ancient practice may support heart health, general fitness, and mental well-being.

The new recommendations for healthy eating emphasize diet over individual nutrients and overturn some long-held beliefs.

Boosting your muscle mass may trigger changes that enhance heart health.

Munching a small handful every day may protect your heart.

Green vegetables and citrus fruits are good natural sources of folate.

If you're among the one in three American adults with high blood pressure, be sure you're getting enough of the B vitamin known as folate. Doing so may lower your odds of having a stroke, a new study suggests.

Cocoa flavanols in chocolate are linked to improved thinking skills and better heart health.

Work with a physical therapist to learn how to use a walker to best advantage so you can take back your independence.

Walkers can put you back in action if you're recovering from an injury or surgery, or if you're struggling with balance and gait problems, fatigue, or muscle weakness. "Walkers help give people their independence back. They improve daily function, and they reduce the risk of falling," says Dr. Clare Safran-Norton, a physical therapist and clinical supervisor of rehabilitation services at Harvard-affiliated Brigham and Women's Hospital.

Supplements can plug dietary gaps, but nutrients from food are most important.

The fresh food you eat is loaded with nutrients necessary for good health, such as magnesium, calcium, and vitamins A and C. But many older adults aren't getting enough nutrients from their diets.

If you stay physically active in your older years, you're preserving your ability to keep moving. That's not just because you're exercising your heart and lungs and keeping your muscles and bones strong, but possibly also because you are warding off the effects of common age-related brain abnormalities called white matter hyperintensities (WMH)—small areas of damage in connections in the brain that are often related to long-term changes in the small blood vessels feeding the brain. High levels of WMH are associated with difficulty walking, but a study published in Neurology March 11, 2015, observed that older adults with WMH who were more physically active suffered less movement problems.

Researchers measured physical activity among 167 older adults with WMH. For the people who were the most active—in the top 10%—greater amounts of brain damage did not affect their scores on the movement tests. But for people who were half as active or less, more brain damage was associated with much lower scores on movement tests.
