Can I skip vaccination if I had COVID?

Evidence suggests that people who've had COVID-19 may have some natural protection against the virus, but will have a much stronger immune response if they also get the vaccine.

Reduce the health risks from "forever chemicals"

Per- and polyfluoroalkyl substances (PFAS) are a group of thousands of manmade chemicals that are widely used in products such as nonstick pans, stain repellants for furniture and carpets, cosmetics, and industrial products. These compounds are dangerous to human health and may lead to immune system problems and increased risk of certain cancers. Avoiding exposure by filtering water and choosing PFAS-free products can help to reduce those risks.

Do BMI numbers add up?

For decades, researchers have used body mass index (BMI) to estimate a person’s body fat mass and predict possible health risks. While BMI is helpful, it can’t accurately measure the type of fat people accumulate, especially among older adults. Monitoring one’s waist size with a simple measuring tape may be a better option.

Can whole grains help whittle your waist?

It appears that people who eat at least three servings of whole grains per day gain fewer inches around their waist than people who eat less than half a serving per day, according to a study published online July 13, 2021, by The Journal of Nutrition.

Do statins increase the risk of dementia?

A study published June 29, 2021, by the Journal of the American College of Cardiology (JACC) found no link between statin use and a higher incidence of dementia in adults ages 65 and older, but other studies have described possible cognitive changes related to statin use. Experts say that the benefits of taking a statin for people who have risk factors for cardiovascular disease generally far outweigh the risks. Statin use can reduce the risk of a heart attack or stroke by 25% to 30%.

Looking past blood pressure numbers

For decades, blood pressure treatment was dictated by a person’s numbers, with a blood pressure less than 140/90 millimeters of mercury (mm Hg) considered normal. But evidence has proved this to be an inadequate goal. Research now suggests an individualized approach to managing blood pressure that considers other heart health risks, lifestyle habits, and family history may be a better way to ward off heart attacks and strokes.

Confused about eating soy?

The FDA wants to pull its support of the health claim that eating soy protein may help reduce the risk of heart disease. The agency proposed the change last fall, citing evidence that questions whether there's any real benefit to heart health. If the FDA goes through with the move, then food makers will no longer be allowed to market soy products with the claim that they can help your heart. But soy won't hurt your heart, and soy does have other benefits.

Rising alcohol use among older adults

In recent years alcohol use by older adults has been trending upward, particularly among women. Drinking too much alcohol can have negative consequences on physical and mental health, and age-related changes in the body can place older adults who drink at additional risk.

Harvard Health Ad Watch: Can a wearable device reduce stress?

Stress can affect sleep, mood, and appetite, and the long-term effects of chronic stress have been linked to health issues like cardiovascular disease, obesity, and Alzheimer's disease. A wearable device claims that it can reduce stress and build the wearer's resistance to stressful situations — but how does it work, and can any of its claims be proven?
