We've been told the importance of eating fruits and vegetables ever since childhood, and yet we still tend to ignore this nutritional advice. In fact, a CDC survey found that only 18% of adults eat the recommended five daily servings of fruits and vegetables.

"The main reason older men have trouble reaching this amount is lack of awareness," says Vasanti Malik, a research scientist in the Department of Nutrition of Harvard's T.H. Chan School of Public Health. "They are not always engaged in their nutrition or aware of the impact fruits and vegetables can have on their health."

Q. I am 65 years old and in good health, and I see my doctor once a year for an annual exam. Should I request a stress test at my next physical?

A. Although heart disease is common in men, routine cardiac stress testing is not recommended for otherwise healthy men. It may seem counterintuitive not to look for heart disease in healthy men, especially when many people know someone who unexpectedly had a heart attack or even died suddenly from a heart problem. Yet, stress testing does not accurately identify men at risk for sudden cardiac death.

Q. Should pregnant or breastfeeding women and their children use sunscreen?

A. The American Academy of Dermatology recommends that people avoid applying sunscreen to the skin of babies younger than 6 months of age, and instead shield them from the sun, keeping them in the shade as much as possible. It's also a good idea to protect them from the sun using clothing, hats, and sunglasses.

Everyday objects from pet supplies to kitchen appliances may seem innocuous, but they can cause injuries, including bone breaks, cuts, and burns. Doctors who treat these injuries often see some common themes. We asked Dr. Tamara Rozental, an associate professor of orthopedic surgery at Harvard Medical School, about what injuries she frequently sees from common items — and ways to stay safe.

Dog leashes

"I see many injuries from dog leashes. People often get tangled and pulled over," Dr. Rozental says. In other instances, fingers get bent, broken, or crushed when people get their hand stuck in the leash and the dog pulls.

Research we're watching

The FDA is warning consumers not to buy in to the idea that a pill can protect your skin from the sun.

There's an old saying: "If you want to stay moving, you have to get moving." But for a lot of us, that's easier said than done.

The Department of Health and Human Services (HHS) says we've become a nation of sitters, and our increasingly sedentary lifestyle has become America's primary health crisis, especially for older adults.

Q. I'm 65 years old and have never had any bone health issues. Should I get a bone density test?

A. Bone density testing is a specialized x-ray technique used to diagnose osteoporosis (thin bones), a condition that increases the lifetime risk of fracture by six times in men.

In the journals

Can higher protein intake build more muscle in older men? Not according to a study in the April 2018 JAMA Internal Medicine.

The researchers randomized 92 men, average age 73, into four groups. One group followed a daily diet containing 0.8 grams (g) of protein per kilogram (kg) of body weight, the daily Recommended Dietary Allowance (RDA) for all adults, and a weekly placebo injection; another consumed 1.3 g/kg and the placebo injection; a third consumed the 0.8-g/kg diet, but also received a weekly 100-mg injection of testosterone, and the fourth group ate a 1.3-g/kg diet and got a weekly testosterone injection. (The testosterone was included to see if higher protein increased the hormone's muscle-growing effect.)
