Want to be happy? Eat more servings of fruit and vegetables a day.
That’s what a study of the eating habits of 80,000 Britons appears to show.
University of Warwick and Dartmouth College scientists used seven measures of well-being: life satisfaction, self-reported health, happiness, nervousness and feeling low, mental well-being and mental disorders in an effort to understand how diet affects mental health and happiness.
Researchers found that mental well-being was greater among those who ate more fruit and vegetables daily — up to seven portions a day. A portion was about 80 grams, or 2.8 ounces.
The researchers are unclear why that was the case and say randomized trials should be performed next to learn more.
The results will be published in the journal Social Indicators of Research.
