The Checkup: How Fruits and Veggies Make You Happy

• Seven. Seven servings of fruits and veggies a day is what you should aim for if you want to be happy, according to a new study. Researchers in the U.K. examined the connection between eating habits and mental well-being, and found that those who eat seven portions of fruits and veggies a day are also the happiest. (For the purposes of the study, a portion was considered to be 80 grams.) The study didn’t distinguish between the kinds of fruits and veggies the more than 80,000 subjects consumed, nor did it determine why there’s a happiness-produce connection to begin with. But still. In a country where most adults and kids eat far fewer fruits and veggies than is recommended, this is certainly news we can use.
