Eight servings of fruit and vegetable may be optimal: study

EATING more fruit and vegetables may make young people happier and boost energy, research suggests.

New Zealand psychologists and health nutritionists collected data from 281 young adults before asking them to complete an online daily food diary for three weeks.

The authors found on the days when the participants ate more fruit and vegetables, they reported feeling calmer, happier and more energetic than they normally did. 

“Our data suggest that young adults would need to consume approximately 7.2 daily servings of fruit or 8.2 servings of vegetables to notice a meaningful [positive] change,” the authors wrote. 

“The current findings suggest that many apples a day is part of a balanced approach to keep the blues away.”
