It isn’t every day that an effective new treatment for some Parkinson’s disease symptoms comes along. Especially one that is safe, causes no adverse side effects, and may also benefit the rest of the body and the mind. That’s why a report in the New England Journal of Medicine showing that tai chi may improve balance and prevent falls among people with Parkinson’s disease is so exciting. This and earlier studies are significant because they suggest that tai chi can be used as an add-on to current physical therapies and medications to ease some of the key problems faced by people with Parkinson’s disease. Since the appearance of the New England Journal of Medicine study, tai chi classes specifically for Parkinson’s disease patients have sprung up across the country, and the benefits of tai chi for Parkinson’s disease have been endorsed by the National Parkinson’s Foundation.

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.
When you decide it’s time to live a healthier lifestyle, you’re likely to get better long-term results if you start improving your diet and increasing physical activity at the same time. It may seem better to improve just one thing at a time. But while you don’t have to make drastic changes overnight, a new [...]
Strength training is a popular term for exercises that build muscle by harnessing resistance against an opposing force. The resistance can come from your body, or from free weights, elasticized bands, or specialized machines. It makes muscles stronger. Another type of training, known as power training, is proving to be just as important as strength training in maintaining or restoring function. As the name suggests, power training is aimed at increasing power, which is the product of both strength and speed. Optimal power reflects how quickly you can exert force to produce the desired movement. Here’s an example: Faced with a four-lane intersection, you may have enough strength to walk across the street. But it’s power, not just strength, that can get you across all four lanes of traffic before the light changes. Likewise, power can prevent falls by helping you react swiftly if you start to trip or lose your balance. Some power moves are strength training exercises done at a faster speed. Others rely on the use of a weighted vest, which is worn while performing certain exercises that are typically aimed at improving functions such as bending, reaching, lifting, and rising from a seated position.
The bombs that exploded on Monday near the finish line of the Boston Marathon killed three people, physically injured nearly 200 others, and traumatized thousands more. Recovery and healing are beginning for the families of those who died, for the injured and their families, and for others touched by this tragedy. For some, healing will be swift. For others it will be measured in small steps over months, and possibly years. The Marathon explosions will leave a legacy of emotional scars along with the physical ones, even among those who weren’t anywhere near the blasts. Some people who were at the scene of the explosions will undoubtedly develop post-traumatic stress disorder (PTSD). But PTSD is not the only response to frightening events. In fact, most people exposed to a trauma do not develop this condition. They may develop an anxiety disorder, for example, or become depressed. Most people do have some emotional response, but the majority develop no illness at all.
Is red meat bad for your heart? A new study suggests it is, but not for the reasons you might expect—like the saturated fat or cholesterol in red meat. A team from a half dozen U.S. medical centers says the offending ingredient is L-carnitine, an amino acid that is abundant in red meat. Their work shows that eating red meat delivers L-carnitine to bacteria that live in the human gut. These bacteria digest L-carnitine and turn it into a compound called trimethylamine-N-oxide (TMAO), which has been shown to cause atherosclerosis, the disease process that leads to cholesterol-clogged arteries, in mice. There’s still a long way to go before we know the full story about L-carnitine and heart disease, but this work suggests that cutting back on L-carnitine (and avoiding L-carnitine supplements) may be good steps for heart health.
For many people, medications are a mainstay for preventing and treating disease. Managing multiple conditions and multiple medications can be confusing, especially if you store some of your pills in the medicine cabinet and others in a kitchen cabinet or pill drawer. Every once in a while, it’s a good idea to take inventory of all of your medications. As a reminder to do just that, the American College of Endocrinology has declared April 15th as National Check Your Meds Day. The college recommends checking to make sure the labels on the medications you got from the pharmacy match exactly what your doctor prescribed. It’s also important to check expiration dates.
Salt is a cheap, easy way to turn on taste buds. That’s one reason why it’s in so many of the foods we eat. It’s so commonly used that most Americans consume more than double the recommended daily limit for it. Three new studies in BMJ (formerly the British Medical Journal) once again confirm the relationship between salt intake and health problems. They show that reducing salt intake can help lower blood pressure and lower the odds of having a heart attack or stroke or developing heart failure. They also show that consuming more potassium is also linked to lower blood pressure and lower risk of stroke. Current dietary guidelines recommend that Americans get no more than 1 teaspoon of salt a day. That’s the equivalent of 2,300 milligrams (mg) of sodium a day. Most Americans get much more than that. It’s possible to cut back by avoiding processed and packaged foods, using herbs and spices to season food instead of salt, and other strategies. It’s best to get potassium from food, especially fruits and vegetables. Green leafy vegetables, beans, and bananas have a lot of potassium.
Chest pain brought on by exercise or stress, a condition known as angina, holds back millions of Americans from living life to the fullest. There’s long been a perception that angina symptoms in women are different than they are in men. Doctors often use the term “typical angina” to describe the angina symptoms that men relate. Symptoms more commonly described by women have been dubbed “atypical angina”—suggesting that women are somehow experiencing an unusual manifestation of heart trouble. A new Harvard study shows that women and men probably experience the same symptoms, but describe them differently. By any name or description, chest discomfort is crucial for women—and their doctors—to pay attention to. And that means acknowledging the possibility of angina no matter how a women describes suspicious chest-related symptoms.
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.
