Today’s Headlines: Blueberries, Money Woes and Self-Esteem

Blueberries, not fruit juice, cut type-2 diabetes risk: Some whole fruits, but not fruit juice, help protect against type 2 diabetes, a new study in the British Medical Journal suggests. At least three servings a week of blueberries, apples or grapes appear to be particularly effective for lowering diabetes risk. The study found that “blueberries cut the risk by 26% compared with 2% for three servings of any whole fruit – but fruit juice did not appear to have the same effect.” The study’s data was drawn from the diets of over 187,000 people in the U.S. (BBC News)

Study: IQ drops with worries over money: Financial woes may hurt more than your wallet. A new study shows that “people worrying about having enough money to pay bills tend to lose temporarily the equivalent of 13 IQ points.” The researchers, a team of economists and psychologists, suggest that “financial stress monopolizes thinking, making other calculations slower and more difficult, sort of like the effects of going without sleep for a night.” (The Seattle Times)

Men’s self-esteem suffers when female partner succeeds, study says: A study in the Journal of Personality and Social Psychology suggests than men may feel worse about themselves when their female partners succeed. Oddly enough, “researchers concluded that men automatically interpreted a partner’s success as their own failure, even when they were not in direct competition.” The same was not true of women. This may be due to learned gender roles, researchers said, or it could be “because ambition and success are qualities that are generally important to women when selecting a mate,” in which case “thinking of themselves as unsuccessful might trigger men’s fear that their partner will ultimately leave them.” (Los Angeles Times)
