Chard
Chard is a highly nutritious veggie. Only one cup can provide up to 3 times the recommended daily intake of vitamin K. Also, it is high in many other nutrients and minerals, such as vitamin A, vitamin E, vitamin C, vitamin K, potassium, iron, manganese, magnesium, copper, and calcium. Chard is low in calories as well, making it a great option for a weight-loss diet. Studies have shown that consuming this food can help improve athletic performance, reduce needed oxygen during exercise, and reduce blood pressure. These effects can be attributed to the high nitrate levels. [6]
