Research we're watching

Replacing just one sugary drink each day with water may reduce your risk of developing diabetes, according to a study published online Oct. 3, 2019, by Diabetes Care. Researchers from Harvard's T.H. Chan School of Public Health looked at more than two decades' worth of data collected in three long-term studies, involving more than 192,000 adults. By tracking beverage intake over time, they found that people who increased their consumption of sugary drinks (including 100% fruit juice) by more than 4 ounces a day over four years had a 16% increase in diabetes risk over the next four years. Turning to "diet" versions might not help, either: an 18% jump in diabetes risk occurred in people who increased their intake of artificially sweetened drinks by more than 4 ounces a day over the same period, although some of that risk could have reflected other factors, said researchers.

The bottom line: If you want to reduce diabetes risk, it's better to skip sweet drinks and stick to unsweetened tea, coffee, or water. When people drank one of those beverages once a day instead of a sweetened drink, diabetes risk dropped by 2% to 10%.

The once-a-year appointment can reveal vital health information for both you and your doctor.

It's usually covered by your health insurance, it doesn't take much time, and it's a great way to learn about your present and future health.

While men often call it the yearly physical, the annual ritual is better named a wellness visit or preventive health appointment. Whatever you call it, men should still have one every year as it remains an important part of primary care, according to Dr. Asaf Bitton, executive director of Ariadne Labs and primary care physician at Harvard-affiliated Brigham and Women's Hospital.

Q. How does a cold virus spread from one person to the next? And what can I do to protect myself?

A. The common cold is most often spread by direct contact with the respiratory secretions of someone who is infected, typically through hand-to-hand contact. Here is how it happens: The person with a cold touches his or her mouth or nose (we do this all day without thinking). The cold viruses are now on the person's hands. The person then touches you, such as by shaking hands. You rub your eyes, nose, or mouth, and the viruses enter your body, and so it goes.

Maintaining proper balance as you age requires attention, strength, and flexibility.

One skill that can sharply decline with age, and often with little warning, is your sense of balance.

"As people age, changes in flexibility, muscle strength and power, body sensation, reflexes, and even mental function all contribute to declining balance," says Dr. Brad Manor, associate director of the Mobility and Falls Translational Research Center with Harvard-affiliated Hebrew SeniorLife. "You need to work on all these factors to maintain a strong sense of balance."

Here are 10 ways to safeguard your life (and health) when an emergency or disaster strikes.

Natural disasters and other kinds of emergencies can strike anywhere and often with little warning. Yet, new data from the University of Michigan National Poll on Healthy Aging show that most adults ages 50 to 80 are ill-prepared for severe weather, long-term power outages, or other emergency situations.

"Older adults should take the time to focus on how they will cope and manage with an emergency," says Dr. Howard LeWine, assistant professor of medicine at Harvard Medical School and editor-in-chief of this newsletter. "A small effort now can protect their health and well-being when an emergency does occur."

Your money might be better spent on something else.

During the winter months, you've likely seen ads for products that claim to give your immune system a boost to help you ward off colds and the flu. But can something in a bottle, whether a vitamin formulation or probiotic, really rev up your immune system to help you stay healthy?

"Unfortunately, the reality is that those kinds of products aren't really offering you any benefit," says Michael Starnbach, a professor of microbiology at Harvard Medical School. "There's no evidence that they help in fighting disease."

Healthful protein, slowly digested carbohydrates, fruit or vegetables serve up best morning mix

As you sleep, your body is hard at work digesting yesterday's dinner. By the time you wake up, your body and brain are demanding fresh fuel. "Breaking the fast" is a key way to power up in the morning. Do it right and the benefits can last all day.

If you miss the day's first meal, notes Dr. David S. Ludwig, a nutrition expert at Harvard-affiliated Children's Hospital Boston, you may start off with an energy deficit and have to tap into your energy reserves.

Yoga promotes physical health in multiple different ways. Some of them derive from better stress management. Others come more directly from the physical movements and postures in yoga, which help promote flexibility and reduce joint pain.

Following are some of the physical benefits of yoga that have a growing body of research behind them. In addition to the conditions listed below, preliminary research also shows that yoga may help with migraines, osteoporosis, balance and mobility issues, multiple sclerosis, inflammatory bowel disease, fibromyalgia, and ADHD.

Your best bet for meeting your health goals is to cook your own meals at home, where you can control the ingredients and portion sizes. However, we all enjoy eating out from time to time. Just keep in mind that restaurant meals—in particular, fast-food meals—are linked with higher intakes of calories, sugar, saturated fat, and sodium, and lower intakes of healthful foods, such as fruits, vegetables, and whole grains. One of the biggest problems you'll face when you dine out is sheer portion size, which has increased dramatically over the years. Those bigger portions translate into more calories, sodium, sugar, and saturated fat.

Fortunately, the dining scene has improved. The FDA now requires chain restaurants to provide consumers with clear and consistent nutrition information on menus, menu boards, and in writing, which can help you make healthier choices. And more and more restaurants are meeting consumers' desires for healthier fare by providing smaller portions, more fruits and vegetables on the menu, more vegetarian options, and lighter preparation styles.

Nonprofit groups offer services that can help you age in place.

The holidays are a time of giving, but they're also a time to put yourself on the receiving list and assess whether you should be taking advantage of free health-related services offered by nonprofit organizations. Services are widely available, often regardless of income. But you might not know they exist. "Most older adults aren't introduced to support services until they're hospitalized or they work with a case manager or social worker," explains Barbara Moscowitz, a geriatric social worker at Harvard-affiliated Massachusetts General Hospital. "You don't have to wait for such an event."

What's available

On the local level, you can often find free or low-cost dental clinics, emotional support groups, meal or grocery delivery services, transportation, in-home health evaluations, exercise classes, health education classes, home evaluations for fall prevention, companion programs, caregiver respite services, or programs to help you navigate difficult chronic health conditions and their treatment.
