5. Swiss Chard
“Swiss chard is one of the healthiest leafy greens around,” says Kotsopoulos. “It helps to boost cardiovascular strength and keeps bones healthy. Plus, it has an abundant source of vitamin K.”
As you probably know, this vitamin is one of the most essential bone-building vitamins, helping to shuttle calcium to your bones, and helping your bones absorb the calcium once it gets there. One cup contains 374 percent of your DV. Eating Swiss chard regularly may also be beneficial to weight loss.
