Healthiest U.S. Metro Areas in 2014

fitnessThe American College of Sports Medicine’s (ACSM) seventh annual American Fitness Index (AFI) ranks Washington, D.C., at the top with a score of 77.3 (out of 100), followed by Minneapolis-St. Paul (73.5), Portland, Oregon (72.1) Denver (71.7) and San Francisco (71). Overall, metro areas in 25 states scored 50 or above; the two lowest-ranking hovered near 25 points.

“The AFI data report is a snapshot of the state of health in the community and an evaluation of the infrastructure, community assets and policies that encourage healthy and fit lifestyles. These measures directly affect quality of life in our country’s urban areas,” says Walter Thompson, Ph.D., chair of the AFI advisory board.

True Grit
August 2014

Why Persistence Counts

classroomSome educators believe that improvements in instruction, curriculum and school environments are not enough to raise the achievement levels of all students, especially disadvantaged children. Also necessary is a quality called “grit”, loosely defined as persistence over time to overcome challenges and accomplish big goals. Grit comprises a suite of traits and behaviors that include goal-directedness (knowing where to go and how to get there); motivation (having a strong will to achieve identified goals); self-control (avoiding distractions and focusing on the task at hand); and a positive mindset (embracing challenges and viewing failure as a learning opportunity).

A meta-study of 25 years of research by John Hattie and Helen Timperley, professors at the University of Aukland, New Zealand, has shown that giving students challenging goals encourages greater effort and persistence than providing vague or no direction. Students aren’t hardwired for these qualities, but grit can be developed through an emerging battery of evidence-based techniques that give educators a powerful new set of tools to support student success.

A famous example of the power of self-regulation was observed when preschoolers that were able to withstand the temptation of eating a marshmallow for 15 minutes to receive a second one were more successful in high school and scored about 210 points higher on their SATs later in life than those with less willpower (Tinyurl.com/StanfordMarshallowStudy).

Ginger and Turmeric Protect Skin from Sun
July 2014

Herbal Extracts Absorb UVB Rays

gingerScientists from Thailand’s Chulalongkorn University have found that extracts from ginger and turmeric may help prevent DNA damage caused by the sun’s ultraviolet B (UVB) rays, a leading cause of melanoma and other skin cancers.

Fifteen herbal extracts were created; each was applied to human keratinocytes, the predominant cell type in the outer layer of skin that can be damaged by the sun’s rays. The researchers measured the ability of each herb extract to absorb ultraviolet radiation and act as an antioxidant, neutralizing free radicals.

Turmeric and ginger extracts absorbed a significant amount of UVB rays before they could damage the skin, according to the results, published in Photochemistry and Photobiology. Each was found to stimulate the synthesis of thioredoxin 1, an antioxidant protein that appears to protect keratinocytes from DNA damage and toxicity to living cells.

Sewage Can Lurk in Bagged Fertilizers

dirtBagged garden fertilizers help plants grow, but store-bought brands can be a scary mix of sewage sludge—treated human, industrial and hospital waste. No federal or state regulations require that sewage sludge, also known as biosolids, be listed on the label. Sludge can also be blended with more natural fertilizers without listing it as an ingredient.

Today’s testing requirements for waste sludge cover only 10 elements and two indicator bacteria; all other contaminants, pharmaceuticals and toxic chemicals that go down the drain of every home and business go right into the fertilizer.

Terms like “organic” and “natural” only apply to some food products, not compost or fertilizer. Arsenic and lead are both considered natural ingredients.

Toxins and heavy metals don’t disappear when exposed to sun or rain; they enter the soil or travel by wind and water runoff into yards and communities and can be absorbed in vegetables, plants and livestock. When we consume foods grown in sludge, we consume whatever the plant takes up from the soil. Also, elements like heavy metals collect in the meat, milk and fat of animals that are fed crops grown in sewage sludge.

To protect the family garden, call the fertilizer manufacturer before purchasing a product to verify ingredients. Ask the nursery or store for labeling that depicts which products are sludgefree and also insist on their use at area schools, parks and playgrounds.
