What should you eat to be happier and more attractive?

Happiness increases with the amount of fruit and vegetables people consume, peaking at 7 portions a day:

Economists and public health researchers from the University of Warwick studied the eating habits of 80,000 people in Britain. They found mental wellbeing appeared to rise with the number of daily portions of fruit and vegetables people consumed. Wellbeing peaked at seven portions a day.

Does 7 servings sound like too much? Stay miserable and get sexy with 3.3. That amount made research subjects notably more attractive.

On average, a difference of about 2.9 servings of fruits and vegetables a day was enough for the students to discriminate on the basis of healthy appearance, with more servings associated with looking healthier. Similarly, about 3.3 servings a day was enough for them to discriminate on the basis of attractiveness — with more servings associated with better looks.(A caveat: One weakness of the study is that most of the participants, and all the artificial faces, were Caucasian.) There you have it: Hoover up 3.3 more servings a day of fruits and vegetables and watch what happens.
