Protein Plus Exercise Equals Less Muscle Loss with Aging

Most Americans get plenty of protein-in fact, their problem isnt too little protein but too much of the calories and saturated fat that accompany such popular protein sources as cheeseburgers or fried chicken. But people over age 50 might need to pay attention to getting adequate protein, not just at dinner time but throughout the day. Tufts researchers are finding that a steady intake of protein from healthy sources, combined with aerobic activity and weight-training exercises, can help counter the loss of muscle mass often associated with aging.

Evaluating Alternatives Against Alzheimers and Dementia

An estimated 5 million Americans age 65 and older have Alzheimers disease-a figure expected to increase 40% by 2025 and to nearly triple by mid-century, according to the Alzheimers Association . Many more suffer from other forms of dementia and from cognitive decline. Science is making unprecedented strides toward preventing and slowing such conditions, however. According to the National Institute of Neurological Disorders and Stroke, Scientists have learned more about the brain in the last 10 years than in all previous centuries, because of the accelerating pace of research in neurological and behavioral science and the development of new research techniques.

Daily Handful of Nuts Linked to Lower Mortality Risk

Eating a daily handful of nuts-about one ounce or three tablespoons-could reduce your risk of dying from the most common causes of death. Results from the largest study of its kind, following nearly 119,000 men and women for up to 24 years, show that regular consumers of any type of nuts were less likely to die from heart disease, cancer and lung disease or from all causes than non-nut eaters. As frequency of nut consumption went up, mortality risk dropped.

Rx for Combating Chronic Conditions: Exercise

A potentially life-saving prescription for fighting heart disease, diabetes and stroke could be as close as those walking shoes gathering dust in your closet. According to an unusual new study, the benefits of exercise in reducing mortality from those leading causes of death match or even exceed the effects of prescription drugs for the same conditions. Patients with heart disease who exercised, for instance, had the same odds of surviving the condition as those given medications such as statins or antiplatelet drugs.

Healthy Diet and Lifestyle Help Prevent Disability with Aging

Unhealthy behaviors such as inactivity, poor diet and smoking have long been associated with a wide range of chronic diseases and risk of death. But a new study reveals that such lifestyle factors can also affect older adults' risk of disability and loss of independence.

Eat Right for Strong Bones That Will Last a Lifetime

Are you feeding your bones a healthy diet? If not, the consequences could be serious. According to the National Osteoporosis Foundation (NOF), some 10 million Americans suffer from osteoporosis, which makes bones less dense and more susceptible to fractures. Another 34 million people are at risk for the condition. Osteoporosis will cause about half of all women over 50 to break a bone at some point in their lifetime, the NOF estimates. One-third of those who suffer hip fractures will require nursing-home care, and one-fifth will die in the first year after the fracture.

Eat Right for a Strong Immune System

As the mercury drops, cold and flu outbreaks soar. Its tempting to believe the marketing claims that this pill or that herbal remedy can protect you, but the science says theres simply no magic bullet to boost your immune system. Eating a healthy diet, however, is even more important during cold and flu season. Experts may not fully understand how specific nutrients aid the immune system, and tests of individual vitamins and minerals against colds…
