Putting your best feet forward

Most older adults can expect to walk more than 100,000 miles during their lifetime, which can take a toll on their feet. With regular foot care, people can address most everyday foot issues like calluses, blisters, and fungus infections. But older adults also need to be mindful about certain problems that can impede their foot health and make mobility difficult, such as heel pain, flat feet, and osteoarthritis.

Do past lifestyle habits affect future health?

The health risks of using tobacco and overusing alcohol begin to drop within days after a person stops using them. However, how past usage may affect a person's longevity is difficult to predict.

The story on fish and heart health

A diet that includes fatty fish, such as salmon, mackerel, sardines, tuna, pollock, and cod, has long been touted to support heart health. Research has found that the health benefit from fatty fish appears to be its high levels of omega-3 fatty acids, which can reduce triglyceride (a type of fat in the blood) and increase "good" HDL cholesterol. Omega-3s also slow plaque buildup in arteries that can cause blood clots and may trigger heart attacks and strokes.

Good intentions, perilous results

Some supplements can interfere with lab tests to diagnose or monitor health conditions, which can lead to life-threatening misdiagnoses or unnecessary additional testing. Biotin (vitamin B7) can skew results from a blood test to diagnose heart attack. Other problematic supplements include vitamin C, which can interfere with blood sugar readings and stool tests; calcium, which can make bones appear denser than they are on bone density scans; and creatine, which can lead to falsely high readings of creatinine, a marker for kidney disease.

About one in three Americans engages in gardening, and the activity became even more popular during the COVID pandemic. Research suggests gardening provides many physical and mental health benefits. It can boost movement, improve diet, fight illness, smooth mood, sharpen brain function, and strengthen social bonds. Gardeners should wear a hat and apply sunscreen to protect against sun exposure. They should also wear gloves to create a barrier against skin allergens on plants and bacteria or fungi in potting soil mixes.

How useful is the body mass index (BMI)?
