Leafy green vegetables are important for a variety of reasons. Many people consider them nutritional superstars because when eaten raw they are one of the best sources of amino acids, which are the building blocks needed for protein in the body. Leafy greens are easy to digest, and they stimulate digestion by encouraging digestive enzymes. They also strengthen the immune system and provide needed nutrients required for proper hormone balance.
Leafy greens are nutritional powerhouses extremely low in calories. For instance, despite the fact 100 grams of spinach contains only 23 calories, it also contains 188% of a person’s daily value of vitamin A and 604% of a person’s vitamin K. In general, leafy greens have numerous vitamins, including many B vitamins and vitamins C, E, and K. They are extremely rich sources of minerals, such as calcium, magnesium, iron, and potassium, and they also provide many phytonutrients, including beta-carotene, lutein, and zeaxanthin. In fact, greens are so nutritious, many greens contain small amounts of Omega-3 fatty acids.
Greens are also packed with fiber. Fiber comes in two types, water-soluble and insoluble, and both are found in plant foods to one degree or another. Water-soluble fiber helps lower cholesterol levels and insoluble fiber promotes regularity, so fiber slows digestion and has little impact on blood glucose levels. Fiber foods have also been linked to low incidences of colon cancer. If you’re interested in learning more about fiber, read Fiber is More Than a Hill of Beans.
