Eat more colors

The color of fruits and vegetables is a sign of nutritional content, says Danielle

Nierenberg, the co-founder of Food Tank, a think tank offering solutions and environmentally sustainable ways of alleviating hunger, obesity, and poverty. Studies show that fruits and vegetables often contain carotenoids, which create the brilliant colors of a variety of fruits and vegetables and protect our cells from oxidation and cellular damage. A richly-colored red tomato also has high levels of lycopene, says Nierenberg, which the American Cancer Society reports can help prevent cancer as well as heart disease.
