There’s almost always something we can do to improve our health and well-being — even at the end of our lives. Palliative care is designed to improve the quality of life for people with life-threatening illnesses and their families by keeping a person comfortable and making sure his or her values and preferences guide the medical team’s actions. For this reason, good communication with your care team — and your loved ones — is essential, even before you or a loved one has developed a serious illness.

This ancient practice can transform the way you think about food and set the stage for a lifetime of healthy eating.

Like most of us, you've probably eaten something in the past few hours. And, like many of us, you may not be able to recall everything you ate, let alone the sensation of eating it. According to a 2011 report from the U.S. Department of Agriculture, the average American spends two-and-a-half hours a day eating, but more than half the time, we're doing something else, too. Because we're working, driving, reading, watching television, or fiddling with an electronic device, we're not fully aware of what we're eating. And this mindless eating—a lack of awareness of the food we're consuming—may be contributing to the national obesity epidemic and other health issues, says Dr. Lilian Cheung, a nutritionist and lecturer at Harvard T.H. Chan School of Public Health.

The microorganisms that inhabit your body can be valuable allies in reducing inflammation and treating disease.

Not too long ago, we thought of all germs as enemies to be destroyed with antibacterial soaps and antibiotic drugs. In the last few years, it's become apparent that the war on microbes is not just a futile enterprise, but also one that could be harmful to our health. The more we learn about the human microbiome—the trillions of single-celled organisms that colonize our skin, nose, digestive system, and vagina—the more we realize that the microscopic critters that live on us and in us may be as important to our health as our body cells.

Experts' advice has changed as we've learned more about the connection between physical activity and health.

If exercise could be packed into a pill, it would be the single most widely prescribed and beneficial medicine in the nation.

Ask the doctor

Q. I have difficulty falling asleep, and melatonin has not worked. I want to avoid medications and I have read magnesium supplements can help. Should I try them?

A. Magnesium is an important element in many biological functions, including nerve and muscle function, so it is often proposed as a natural treatment. It has gained some acceptance as a preventive treatment for migraine headaches, but there is not strong scientific evidence for its use with insomnia.

In the journals

A study published in the journal Frontiers in Aging and Neuroscience (Aug. 25, 2015) has found that fitness levels in older adults correlates with activation in areas in the brain's frontal lobe responsible for executive function—mental skills used to manage time, plan and organize, and remember details. The researchers examined brain imaging and cardio fitness data from 128 adults ages 50 to 80. Cardio fitness level was determined by measuring maximal oxygen consumption (VO2 max) while a person walked at increasing speed on a treadmill. Executive function skills were measured by how fast and accurately a person responded to computer stimuli like numbers and letters.

The results: People with a higher cardiorespiratory fitness level showed greater brain activation in the frontal lobe. They were also better at performing two simultaneous tasks compared with a single one. This is important since older adults have more difficulty processing multiple tasks, says the researchers. While this study found a link between good cardio health and better cognitive function, more research is needed to show you can improve your brain function by increasing your fitness.

Even if you are active, increasing the time you spend standing every day may further lower your odds of becoming obese, says a new study from the American Cancer Society.

The researchers studied more than 7,000 patients, ages 20 to 79, and reviewed the association between their standing time and their risk of obesity. They looked at specific measurements—such as body mass index, waist circumference, and body fat percentage—and metabolic syndrome, a clustering of factors that increases the risk for heart disease, stroke, and diabetes.

A high-sugar diet may raise heart disease risk. But no-calorie sweeteners aren't ideal alternatives.

If you have a sweet tooth, your heart may be paying the price. Diets high in added sugars have been linked to a host of health woes, including obesity, high blood pressure, high cholesterol, and even a higher risk of dying of heart disease.
