The Exercise Advantage

Taking a brisk walk or  bike ride may stave off cognitive decline better than reaching for the daily crossword puzzle, says a new study published in the journal Neurology. Researchers at Scotland’s University of Edinburgh reviewed the medical records of more than 600 Scots born in 1936 that were given MRI scans at age 73.
“People in their 70's that participated in more physical exercise, including walking several times a week, had less brain shrinkage and other signs of aging in the brain than those that were less physically active,” says study author Alan J. Gow, Ph.D.
Surprisingly, the study showed that participating in mentally and socially stimulating activities, such as visiting family and friends, reading or even learning a new language, did little to ward off the symptoms of an aging brain. Study participants will undergo a second MRI scan at age 76, and researchers plan to compare the two scans to see if the links between exercise and better brain health hold up.

Stone Fruits Keep Waistlines Trim

Some favorite summer fruits, like peaches, plums and nectarines, may help ward off metabolic syndrome, a collection of conditions including high blood sugar levels and excess fat around the waist that can lead to serious health issues such as stroke, heart disease and diabetes. A study by Texas A&M AgriLife Research, presented at the American Chemical Society’s 2012 National Meeting & Exposition, reported that pitted fruits contain bioactive compounds that can potentially fight the syndrome.
According to food scientist Luis Cisneros- Zevallos, Ph.D., “The phenolic compounds in the fruits have anti-obesity, anti-inflammatory and antidiabetic properties… and may also reduce the oxidation of the bad cholesterol, or LDL, which is associated with cardiovascular disease.”
