A new study that linked eating more protein to lower risk of stroke isn’t the last word on the subject. But that doesn’t make dietary protein any less vital, especially in older adults who are at greater risk for malnutrition and illness. How much protein is enough? Current guidelines for adults of any age recommend 0.8 grams of protein per kilogram of body weight. Do older people need more protein than younger ones? That’s still an open question.
Resveratrol, an antioxidant found in red wine and certain foods, has been touted as a natural way to slow aging and fight cancer, obesity, heart disease, and diabetes. As promising as it sounds, we don’t really know how resveratrol affects humans, since most studies have been conducted on animals and microbes. A study out this week from the Johns Hopkins University School of Medicine found no link between consumption of resveratrol from food and rates of heart disease, cancer, and death in a study of older men and women living in Italy’s Chianti region. The disappointing results don’t mean that resveratrol and other molecules like it won’t help extend the lifespan or protect against the development of aging-related diseases. Higher doses may be needed to do that. What’s needed now are trials to determine if taking high-dose resveratrol supplements is safe.
There are plenty of good reasons to be physically active. Big ones include reducing the odds of developing heart disease, stroke, and diabetes. Maybe you want to lose weight, lower your blood pressure, prevent depression, or just look better. Here’s another one, which especially applies to anyone experiencing the brain fog that comes with age: exercise changes the brain in ways that protect memory and thinking skills. In a study done at the University of British Columbia, researchers found that regular aerobic exercise, the kind that gets your heart and your sweat glands pumping, appears to boost the size of the hippocampus, the brain area involved in verbal memory and learning.
An estimated 43.5 million Americans provide in-home, long-term care for older adult family members with a chronic illness. In a new JAMA survey, caregivers are typically women who spend about 20 to 40 hours a week providing care. Most caregivers feel abandoned and unrecognized by the health care system. Spousal caregivers face greater challenges than caregivers helping a parent for a variety of reasons, one of which is that they tend to be older. Many caregivers don’t know about, or take advantage of, services and support systems such as respite care, help with non-medical services such as housekeeping and cooking, counseling, and more. The Caregiver’s Handbook, a Special Health Report from Harvard Medical School, includes detailed information that can help women and men provide better care for their loved ones and take care of themselves.
Some people assume that women become less interested in sex as they age. That may be true for some women, but it isn’t for others. New research published in JAMA Internal Medicine reports that women between the ages of 40 and 65 who place greater importance on sex are more likely to stay sexually active as they age. In other words, if it’s important to you, you’ll keep on doing it. There are many reasons why sex may slow down for women when they get older, not least of which is menopause. It can cause decreased interest in sex and physical problems that make sex difficult, or even painful. Poor health can also get in the way of having sex. So what’s a woman to do? Seek treatment, which may not be as complicated as you think.
Diverticulitis, an unpleasant condition that occurs when tiny pouches inside the large intestine become inflamed, can cause intense lower abdominal pain, diarrhea, constipation, a fever, and sometimes a good deal of rectal bleeding. Following a liquid diet for a while can help treat it, but antibiotics, and sometimes even surgery, may be needed. A new study in JAMA suggests that these treatments may be overused.
University of Michigan researchers reviewed the results of 80 studies of diverticulitis and its treatment. While the team agreed that antibiotic use and surgery are sometimes necessary, it concluded that there should be a lesser role for aggressive antibiotic or surgical intervention for chronic or recurrent diverticulitis than was previously thought necessary. Some studies suggest that exercising, controlling weight, and eating a high-fiber diet can prevent diverticular disease. It can also bring relief from constipation, better cholesterol control, and make for more filling meals. Adults should get 25 to 30 grams of dietary fiber every day. It’s best to get it from high-fiber foods, such as beans, whole grains, vegetables, and fruits. Some people need a fiber supplement.
If you have trouble finding the motivation to break away from the television and exercise, try couchersizing—staying on or near your couch and exercising during commercial breaks. Why bother? A growing body of evidence links the amount of time spent sitting to illness and even death. And just minimizing long periods of inactivity, like exercising during commercial breaks, can help reduce the risk of injury and may even help you live longer. You can work many different muscle groups while seated upright on a couch. Want to get your heart rate up, work the oblique muscles on the sides of the abdomen. To whittle your waist, try twisting your torso from side to side for the length of a commercial break. You can even exercise while lying on the couch.
Overeating during the holidays is practically a tradition. But overindulging can lead to weight gain, fatigue, and guilt. There are several tactical strategies you can employ to get you through the season of eating. Plan ahead: Find out when you’ll be eating, and plan your day around the meal; if you can bring a dish for the buffet, bring something healthy. At the buffet: Grab a salad plate instead of a dinner plate, and choose wisely; don’t waste calories on foods that aren’t special. At the table: Pace yourself by taking small bites, chewing slowly, and sipping water in between bites. Slowing down helps your brain get the message that you’re full. If all else fails: Don’t beat yourself up. Just get back to a healthy eating plan as soon as possible.
It’s been a big year for the Mediterranean diet. Convincing evidence published in 2013 has shown that this kind of eating pattern is effective at warding off heart attack, stroke, and premature death. While you probably get the biggest payoff by adopting such a diet early in life, a new study shows that doing it during midlife is good, too. In the study, women who followed a healthy diet during middle age were about 40% more likely to live past the age of 70 without chronic illness and without physical or mental problems than those with less-healthy diets. The healthiest women were those who ate more plant foods, whole grains, and fish; ate less red and processed meats; and had limited alcohol intake. That’s typical of a Mediterranean-type diet, which is also rich in olive oil and nuts.
A slowdown in the output of the thyroid gland can cause many problems, ranging from extreme fatigue and depression to intolerance to cold, weight gain, dry skin, and dry hair. Millions of Americans have an underactive thyroid, a condition known as hypothyroidism. The symptoms can usually be controlled with a daily dose of synthetic thyroid hormone called levothyroxine. Who actually benefits from taking levothyroxine is being called into question. New evidence suggests that many people with borderline hypothyroidism may be taking this medication unnecessarily.
