Greens charge you with optimism



People who prefer to eat fruit and vegetables are likely to be more optimistic, thanks to higher levels of plant compounds called carotenoids in their blood, says a new research.

Previous studies have shown that high blood levels of antioxidants, of which carotenoids are one form, may be a marker of good health. A commonly-known carotenoid is beta-carotene, found in high levels in orange fruit and green, leafy vegetables.

Antioxidants help keep other molecules in the body from producing free radicals, which can damage cells and contribute to disease.

"Individuals with greater optimism tended to have greater levels of carotenoids such as beta-carotene," said Julia Boehm, of the Harvard School of Public Health, who led the study, the journal Psychosomatic Medicine reported.
