New research from the University of Navarra in Spain shows that exercise can have a significant positive impact on older seniors.
Scientists recruited 24 adults aged 91–96 and divided them into a nonexercise control group and a “multicomponent” exercise group. The primary focus was to learn how exercise would impact “muscle power output, muscle mass, and muscle tissue attenuation; the risk of falls; and functional outcomes in frail nonagenarians.”
The heart is an incredible organ, not only delivering a constant, reliable stream of life-giving oxygen and nutrients, but also responding instantly to challenges like stress, cardiovascular workouts and high-intensity bursts of energy.
“The human brain seems to benefit from physical activity at each age. Moving matters—especially for those brain regions that are important for learning and memory, such as the hippocampus,” said Carsten Diener, PhD, to IDEA Fitness Journal, as a result of new research available in The World Journal of Biological Psychiatry (2013; doi: 10.3109/15622975.2013.803600).
Fat may seem like the enemy of civilized people—especially sedentary ones. Yet we cannot live without it.
Fat plays a key role in the structure and flexibility of cell membranes, and it helps regulate the movement of substances through those membranes. Special types of fat, known as eicosanoids, send hormone-like signals that exert intricate control over many bodily systems, mostly those affecting inflammation or immune function.
Researchers from the Arnold School of Public Health at the University of South Carolina reported recently in PLOS ONE (2013; 8 , e76632) that 40 years of nutrition information from the National Health and Nutrition Examination Survey—the gold standard database for such information—may be fatally flawed.

For anyone who wants to get slim or maintain a healthy body weight, reading food labels is widely considered a vital dietary strategy. Supermarkets have thousands of them, those black-and-white Nutrition Facts labels telling shoppers how many calories each portion of a product contains. Many recipes in magazines and diet books also indicate the calories you’ll take in with every serving. But now science is showing that not all calories are created equal and those numbers aren’t always, well, black and white.
Childhood obesity, inactivity and poor food choices are taking a toll on today’s youth. In some cases, structured exercise is encouraged for weight management. Unfortunately, this approach doesn’t seem to be working.
