Studies promote the many health benefits of a vegetarian diet, but you don't need to go full veggie to reap the rewards.

Most men recognize the value of a vegetarian diet, but following one can feel daunting. "Men's diets tend not to change much as they age, and they stick with their favorite foods," says Dr. Qi Sun, an assistant professor in the Department of Nutrition at the Harvard T.H. Chan School of Public Health. "A change to vegetarianism can feel overwhelming and confusing and thus may not be sustainable."

A solution is to become a "semi-vegetarian": adopt a plant-based diet in which you cut out the red and processed meat and eat healthier animal products like seafood and poultry only occasionally.

Constipation may be unpleasant and embarrassing, but it should never be ignored. About one-third of adults ages 60 and older report at least occasional constipation, which can leave them feeling bloated, uncomfortable, and sluggish.

"It's an incredibly common problem, especially among older men, but it's important to address and manage, as it can affect your nutrition and quality of life," says Dr. Judy Nee, a gastroenterologist with Harvard-affiliated Beth Israel Deaconess Medical Center.

Research we're watching

Because several studies have connected inflammation to bone loss and fractures, researchers from Ohio State University wondered if dietary choices that contribute to inflammation are also related to declines in bone density.

The team looked at the diets of 160,191 postmenopausal women enrolled in the Women's Health Initiative and assigned each of them a dietary inflammation score based on 32 foods the women reported consuming in the three months prior to their enrollment. All the women completed dietary questionnaires and had scans to measure bone density at the beginning of the study and three and six years later.

Some people live long lives with no disease or serious illness. What can they teach you about healthy living?

You won't live forever, but it may be possible to live a long and maybe disease-free life by following the lead of "wellderlies."

This is a term to describe a special group of people who have reached ages 90 to 100 without having any major health issue or disease. And if they do get sick, it often happens late in their life and a short period before death.

Sharpening your culinary skills (or developing new ones) can improve your diet, nutrition, and social life.

We tend to cook less as we age. Why cook when you can zap something in the microwave, pour something ready-to-eat into a bowl, or speed-dial for takeout? But this quick-eating trend has made many men adopt diets that put them at risk for weight gain, heart disease, and diabetes.

"Many older men have never developed or have lost touch with kitchen skills, and thus have become too dependent on processed and prepared foods," says Dr. David Eisenberg, of the Department of Nutrition at the Harvard T.H. Chan School of Public Health.

Terms like "healthy" or "natural" can be meaningless or misleading.

If you're like most nutrition-minded shoppers, the word "healthy" on the front of a package can be a big draw. "When you're stuck in a situation where processed foods are the only thing available to you, it can be helpful to know which foods are healthier than others," says Dr. Walter Willett, chair of the Department of Nutrition at the Harvard T.H. Chan School of Public Health.

Yet these days you're on shaky nutritional ground if you rely on front-of-package claims like "healthy" to determine which soup, sauce, cereal—or other canned, bottled, boxed, or bagged food—is the best choice. A food marked "healthy" may be loaded with sugar or refined carbohydrates.

In preliminary research, sucralose and acesulfame potassium increased insulin levels, although more studies are necessary to determine whether they—or other artificial sweeteners—increase the risk of insulin resistance.
