Eating seven or more portions of fruit and vegetables a day reduces your risk of death at any point in time by 42 percent compared to eating less than one portion, reports a new study. This is the first study to link fruit and vegetable consumption with all-cause, cancer and heart disease deaths in a nationally-representative population, the first to quantify health benefits per-portion, and the first to identify the types of fruit and vegetable with the most benefit.

U.S. States' personalities linked to their politics

Posted: 31 Mar 2014 02:06 PM PDT

If one state's citizens are more agreeable and another's more conscientious, could that influence how each state is governed? A recently published study suggests it could. Political scientists matched personality data from more than 600,000 Americans with state-level measures of political culture, and found striking results.

Rural versus urban causes of childhood concussion

Youth living in rural areas are more likely to sustain concussions from injuries involving motorized vehicles such as all-terrain vehicles and dirt bikes, whereas youth living in urban areas suffer concussions mostly as a result of sports, research finds.

Can gratitude reduce costly impatience?

Posted: 31 Mar 2014 07:02 AM PDT

In a potentially landmark study, a team of researchers demonstrate that feelings of gratitude automatically reduce financial impatience. The human mind tends to devalue future rewards compared to immediate ones -- a phenomenon that often leads to favoring immediate gratification over long-term wellbeing. As a consequence, patience has long been recognized to be a virtue. And indeed, the inability to resist temptation underlies a host of problems ranging from credit card debt and inadequate savings to unhealthy eating and drug addiction.

Academic workplace bias against parents hurts nonparents too

Posted: 31 Mar 2014 07:01 AM PDT

A new study shows that university workplace bias against scientists and engineers who use flexible work arrangements may increase employee dissatisfaction and turnover even for people who don't have children. The work-devotion schema -- the idea that one's career requires intense time commitments and strong loyalty -- is a mandate that is unconsciously part of most professional workplaces and underlies the flexibility stigma.

Can vitamin A turn back the clock on breast cancer?

Posted: 31 Mar 2014 06:55 AM PDT

A derivative of vitamin A, known as retinoic acid, found abundantly in sweet potato and carrots, helps turn pre-cancer cells back to normal healthy breast cells, which may help explain why some clinical studies have been unable to see a benefit of vitamin A on cancer: the vitamin doesn't appear to change the course of full-blown cancer, only pre-cancerous cells, and only works at a very narrow dose.

New statistics show breast lift procedures are growing at twice the rate of breast implant surgeries. Since 2000, breast lifts have grown by 70 percent, outpacing implants two-to-one. Breast implants are still the most performed cosmetic surgery in women, but lifts are steadily gaining. In 2013, more than 90,000 breast lift procedures in the United States.

Brawn matters: Stronger adolescents, teens have less risk of diabetes, heart disease

Posted: 31 Mar 2014 05:36 AM PDT

Adolescents with stronger muscles have a lower risk of heart disease and diabetes, according to a new study that examined the influence of muscle strength in sixth grade boys and girls. Stronger kids also have lower body mass index (weight to height ratio), lower percent body fat, smaller waist circumferences, and higher fitness levels, according to the study that suggests that muscle-strengthening activities may be important to kids' heart health.
