Contain a variety of nutrients

Leeks are nutrient-dense, which means they are low in calories while being abundant in vitamins and minerals. Cooked leeks provide only 31 calories per 3.5-ounce (100-gram) serving. At the same time, they're abundant in provitamin A carotenoids like beta carotene. These carotenoids are converted by your body into vitamin A, which is necessary for eyesight, immunological function, reproduction, and cell communication.

They're also high in vitamin K1, which is essential for blood clotting and heart health. Meanwhile, wild ramps are high in vitamin C, which helps with immune function, tissue healing, iron absorption, and collagen formation. In fact, they contain almost twice as much vitamin C as the same amount of oranges. Leeks are also a strong source of manganese, which may help lessen PMS symptoms and enhance thyroid health. Furthermore, they contain trace levels of copper, vitamin B6, iron, and folate.
