Protein Supplements May Not Help Older Adults Build Muscle

A recent study published in the Journal of Nutrition found that consuming protein supplements did not help active older men build more muscle or gain more strength than resistance exercise training alone. Forty-one men with an average age of 70 completed whole-body resistance training three times a week for 12 weeks. Half the group drank a supplement containing 21 grams of protein after exercise and every night before bed. The other half drank a beverage with the same number of calories but no protein. At the end of the study period, while both groups were able to lift more weight and tests showed increased muscle mass, the protein group did not improve any more than the placebo group.

Muscle Loss, Obesity, and Cognitive Performance

As people get older, the body tends to lose muscle mass and strength. This process is called sarcopenia, a term coined by Friedman School professor and former dean Irwin Rosenberg. Sarcopenia can make activities of daily life more difficult and increase risk of falls. A recent study in the journal Clinical Interventions in Aging looked at whether sarcopenia could be a predictor of reduced cognition.

Is Extra Protein Enough to Preserve Muscle With Aging?

Protein is essential to good health. You need it to make hair, blood, enzymes and antibodies-and, of course, muscle. The problem: With aging we tend to gradually lose muscle size, strength and function-a relatively common condition called sarcopenia. It may seem like a no brainer to boost your dietary intake of protein to help prevent sarcopenia and the frailty and increased risk of falls it can lead to.

Long-Term Couples Sense of Smell and Taste Become More Similar Over Time

The longer couples stay together, the more similar their smell and taste preferences become, researchers report in Appetite. Although a number of studies have found that romantic partners become more similar in various ways over time, this is the first study to see if this compatibility effect extends to smell and taste, which help to shape food preferences.

The Link Between Your Walking Pace and Aging Well

Walking may seem like a pretty simple activity. But, several different parts of your body are involved, like your heart, lungs, nerves, muscles and bones. So, your walking pace may slow if you're having a problem in one or more of these parts of the body.

Keeping Your Arteries Young

It's common to develop significantly stiffer arteries and high blood pressure as we age past our 50s. Healthy lifestyle factors may go a long way toward slowing this process. A new study published in Hypertension suggests healthy vascular (blood vessel) aging may be possible even in people 70 years and older.

Drink Coffee, Live Longer?

Some people view coffee as a guilty pleasure. But, research suggests drinking coffee may actually have some health benefits. That evidence includes two new, large observational studies of diverse populations published in the Annals of Internal Medicine. Both found drinking coffee was associated with a modestly (less than 20%) reduced risk of dying from various conditions, compared to not drinking coffee.

Fried Potatoes: A Strike Against Longevity?

Eating fried potatoes (such as French fries, potato chips and hash browns) two or more times a week was associated with twice the risk of dying prematurely, compared to eating fried spuds no more than once a month, showed a new observational study in the American Journal of Clinical Nutrition.

Live Longer: Improve Your Diet Quality Long Term

Improving your eating pattern and sticking to these changes for the long haul may have a big impact on reducing your risk of dying prematurely. Those were the findings of a new study published in the New England Journal of Medicine.

Linking Leisure Screen Time & Mortality Risk

Swapping 30 minutes of daily TV or home computer use (leisure screen time) with activities like leisurely walking, gardening, home improvement projects or formal exercise was associated with a 3 to 13% decreased risk of premature death.
