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.”

Red, White and True

Bag the guesswork of grocery shopping and let the American Heart Association (AHA) Heart-Check mark help identify healthy foods. The red-and-white icon, created in 1995 and now found on product packaging, is a solid first step in building a heart-friendly diet. The AHA is now beginning to include foods with high levels of monounsaturated and polyunsaturated fats—the “good” fats—in the Heart-Check program. Updated requirements also covering sodium, sugar and fiber will take effect in 2014 to allow food manufacturers time to reformulate their products.

Four month old Baby Justice arrived in Denver today on transport from Gallup, New Mexico to Misha May Foundation Dog Training and Rescue. Attached are 2 of his photos from when he was with his New Mexico Angels receiving treatment for his horrible neck wound, and love for his broken spirit. Justice is the sole survivor of his family group which included mom and 5 siblings. He was dehydrated, starving and injured when he was finally caught. He had been abused by humans and attacked by dogs. I met the transport and was surprised at how small he and his crate were. So quiet and still. I took him, crate and all, so as not to threaten him with unfamiliar touch. At my house, I had his apartment ready - a huge Great Dane sized crate. I simply put him, small crate and all, into the large crate. I opened his small crate door to give him access to additional blankets, food, water (with Rescue Remedy) and an elimination area. He is cuddled with his ...

The Saltshaker Thief

Before reaching for the saltshaker, consider that excessive dietary salt not only burdens the kidneys and increases the risk of hypertension; it may also deplete vital calcium. Research by Canadian medical researchers at the University of Alberta recently discovered an important link between sodium and calcium, which appear to be regulated by the same molecule in the body. When sodium intake becomes too high, the body excretes it via urine, taking calcium with it and creating a risk for developing kidney stones and osteoporosis. So, pass the pepper instead.

Dirty Pool: Great Lakes Under Siege by Global Warming

Don Scavia, director of the University of Michigan Graham Sustainability Institute, stated in a regional leaders’ conference that climate change is aggravating the effects of devastating algae blooms in the Great Lakes by increasing the intensity of spring rains that wash phosphorus into the water. Rampant algae levels degrade water quality because as algae decompose, oxygen levels can drop low enough to kill fish. After the United States and Canada signed the initial Great Lakes Water Quality Agreement in 1972, many local governments banned detergents containing phosphorus and the algae problem faded, but it has returned in the past decade. Analysts note that while the practice of planting crops without plowing the ground may help prevent erosion, it leaves high concentrations of fertilizer phosphorus in the upper layers of soil, where it easily runs off into waterways. A task force of academic and government experts has recommended more than 50 helpful practices, including prov...

Keep Tabs on Radiation Exposure

The cumulative exposure to ionizing radiation used in medical diagnostic tests from dental and chest X-rays, mammograms, heart health exams and other procedures adds up, often reaching or surpassing the recommended lifetime limit of 100 milliSieverts (mSv) set by the American College of Radiology, according to a recent Harvard Medical School advisory. Among the tests that emit ionizing radiation are computerized tomography (CT scans), cardiac catheterizations, coronary CT angiograms, cardiac calcium scoring and some types of stress tests. Heart tests that pose no radiation risk include electrocardiography (ECG), echocardiography, ultrasound and magnetic resonance imaging (MRI). Dr. Warren Manning, chief of noninvasive cardiac imaging and testing at Beth Israel Deaconess Medical Center, in Boston, and a Harvard Medical School professor, advises, “One or two CT scans over a lifetime is appropriate. But if you have a condition that requires repeated monitoring, a test that does not exp...
