Do-it-yourselfers, take heart. Here’s something else to do at home that can have a substantial benefit on your health: measure your blood pressure. It’s easy, inexpensive, and helps control blood pressure better than visits to the doctor. The latest evidence for the benefits of home blood pressure monitoring comes from researchers in Minnesota. In a 12-month clinical trial, 72% of those doing home monitoring had their blood pressure under control compared to 57% who received usual care. The benefits persisted six months after the program had ended. Anyone can monitor blood pressure at home. You can buy a good home blood pressure monitor at a pharmacy or online merchant for anywhere from $50 to $100. Some insurance companies cover the cost.

The Mediterranean diet has been getting a lot of press as being the very best for health. But there’s another diet that appears to be equally good: a vegetarian diet. A study published in JAMA Internal Medicine found that people who ate a vegetarian diet were 12% less likely to have died over the course of the five-year study than nonvegetarians. The benefits were especially good for men, who had a significant reduction in heart disease. This study underscores the idea that meat consumption influences long-term health, and not in a good way. Should you consider ditching the Mediterranean diet and becoming a vegetarian instead? Either one is healthier than the typical American diet, so it’s really a matter of personal choice.
Adding more protein to the diet and cutting back on carbohydrates, especially highly processed carbs, is an eating strategy adopted by a growing number of people. A new study in the Journal of Nutrition Education and Behavior found that 43% of women surveyed are using the practice of eating more protein to prevent weight gain, and this strategy was associated with weight loss. It isn’t necessary to eliminate all carbohydrates and focus only on protein. Such an eating strategy may have a short-term payoff for weight loss, but it may also come with some long-term risks. Tips for getting a healthful mix of nutrients include adding the healthful trio of fat, fiber, and protein to each meal; avoiding highly processed foods; and choosing the most healthful sources of protein, such as fish, poultry, eggs, beans, legumes, nuts, tofu, and low-fat or non-fat dairy products.
Physical and mental activities are both important for protecting your thinking skills and warding off dementia. But does one trump the other? A study published yesterday in JAMA Internal Medicine tried to tease out if one was better than the other for brain health. Researchers recruited 126 older adults who felt that their memory or thinking skills had recently gotten worse, and divided them into four groups. All were asked to do an hour of mental activity three times a week and an hour of physical activity three times a week. What differed were the intensities of these activities. After 12 weeks, scores on thinking tests improved across the board. The big surprise was that there weren’t any real differences in improvement between the groups. The researchers concluded that the amount of activity is more important for stimulating the brain than the type of activity, because all of the participants both exercised and engaged in mental activities each week.
Americans are a diverse lot, so it’s no surprise they give different answers when asked about their well-being. But it seems that well-being differs from state to state, too. In the latest Gallup-Healthways Well-Being Index, which gauges the physical and emotional health of people in all 50 states, residents of Hawaii reported the best sense of overall well-being while West Virginia residents reported the worst. The index calculates overall well-being based on six quality of life categories, each of which is made up of several components. Poll respondents in Hawaii had the highest scores in the emotional health and work environment indexes, and were most likely to say they were thriving. People in West Virginia were most likely to say they were not thriving, and had the worst emotional health, the worst health habits, the most diagnoses of depression, and high rates of obesity. People in the other 50 states fell in between. It’s possible to change both emotional and physical well-being, and improve happiness.
An army of nutrition experts is constantly reminding us that most fast food is bad for health. But they’re not around to back you up when your children or grandchildren unleash powerful weapons of cuteness to convince you to stop at a fast-food chain. It’s hard not to give in when the ones you adore put on the pressure, even when they’re older. One new study links several weekly fast-food meals with increased risks of asthma, rhinitis, and eczema. Another shows that when kids eat out they take in up to 300 more calories than when eating at home. Stacey Nelson, a registered dietitian who is a clinical nutrition manager at Harvard-affiliated Massachusetts General Hospital, offers some advice for when fast food is the only option.
The holiday season gets all the hype at this time of year, but the flu season needs your attention as well. It has come early this year—the earliest since 2003, according to the Centers for Disease Control and Prevention (CDC)—and is expected to be severe. In the last month, new cases of flu in the U.S. have gone from a few hundred a week to more than a thousand a week. Forty-eight states and Puerto Rico have already seen lab-confirmed cases of the virus, and five children have died from it. Getting vaccinated and washing your hands often are your best bets against getting flu. The vaccine isn’t an anti-flu guarantee, but it can reduce your risk by up to 80%. Yet barely one-third of Americans have been vaccinated against the flu so far this year. Why aren’t more people getting a flu shot?
Do you have trouble sleeping? If you’re carrying extra pounds, especially around your belly, losing weight and some of that muffin top may help you get better ZZZs. So say researchers from Johns Hopkins University School of Medicine, who presented their findings at this year’s annual meeting of the American Heart Association. In a six-month trial that included 77 overweight volunteers, weight loss through diet plus exercise or diet alone improved sleep. A reduction in belly fat was the best predictor of improved sleep. Among people who are overweight, weight loss can reduce sleep apnea, a nighttime breathing problem that leads to frequent awakenings. Exercise has also been shown to improve sleep quality. Despite what thousands of websites want you to believe, there are no exercises or potions that “melt away” belly fat. Instead, the solution is old-fashioned exercise and a healthy diet.
For all too many people, using a tablet computer is a pain in the neck, shoulders, and back. Why? Widely popular tablets like the iPad, Nook, Kindle Fire, and Xoom are so light and easy to handle that you can hold one on your lap or in your hand. That can put you in a position that’s bad for your neck, shoulders, and back. In a study of 15 experienced tablet users, Harvard School of Public Health researchers found that working with a tablet held on the lap or placed flat on a table makes the neck bend much more than does working with a desktop or notebook computer. Neck-wise, the best tablet orientation was having it propped up on a table. Next time you expect to be working with a tablet computer for more than a few minutes, place it on a table and use a case that holds it at a comfortable viewing angle. Shift your hands, your weight, or even stand up when you can. And take a break every 15 minutes.
Succulent tomatoes are far more than just a delicious fruit. Eating them may also help lower your risk of stroke, likely due to the lycopene they contain. Lycopene is a powerful antioxidant that eliminates dangerous free radicals that can damage DNA and other fragile cell structures. Past research has shown that a diet rich in lycopene-containing foods may help lower the risk of prostate and other cancers. Now, in a report just published in the journal Neurology, a team of Finnish researchers has linked higher lycopene levels in the blood to protection against stroke. The researchers suggested that lycopene, in addition to its ability to attack free radicals, may also reduce inflammation and cholesterol, improve immune function, and prevent blood from clotting. All of these may help reduce ischemic strokes, which are caused by clot-caused blockages in blood flow to the brain. It’s best to get lycopene from food—tomatoes and watermelon are excellent sources—not supplements.
