Health briefs: Time for a Facebook break?

  • Updated: February 2, 2013 - 6:02 PM

Is Facebook making you hate your life? Are you jealous of everyone? If so, it might be time to take a break from Facebook. Scrolling through photos of other people's vacations and awesome nights out may be a threat to your sense of happiness, said a team of German researchers in a study titled "Envy on Facebook: A hidden threat to users' life satisfaction?" And if you are the type of person who lurks on Facebook without contributing much yourself, chances are your sense of life satisfaction is even lower, said scientists at Humboldt University in Berlin and Darmstadt's Technical University.

Tuberculosis can hide in bone marrow, lying dormant after aggressive drug therapy and emerging years later to re-infect, investigators said in Science Translational Medicine journal.

EAT YOUR BERRIES

Young women who eat plenty of blueberries and strawberries may have a reduced risk of heart attack, a study has found. The reason, researchers believe, is that those fruits, like other red and blue fruits and vegetables, have high concentrations of anthocyanin, a flavonoid that may help lower blood pressure and improve blood vessel function.

Beginning in 1991, researchers at Harvard tracked more than 100,000 women ages 25 to 42 with food-frequency questionnaires every four years through 2009. The scientists reported last month in the journal Circulation that compared with those below the 20th percentile in anthocyanin intake, those above the 80th percentile were 32 percent less likely to have a heart attack. Other flavonoids were not significantly associated with reduced risk. Women who ate more than three servings of blueberries or strawberries a week -- the most common anthocyanin-rich foods consumed -- had a 34 percent lower risk than those who ate less. However, lead author Eric Rimm, an associate professor at Harvard, cautioned: "This is not a magic bullet."
