No diet is truly optimized without a healthy amount of leafy greens. These plant foods are truly a miracle of nature, and are loaded with vitamins and minerals; they also are low in calories so you can eat plenty of them without gaining weight. Leafy greens can be eaten in sandwiches, be part of casseroles and can be eaten in numerous types of salads.
What are leafy greens?
There are both common and relatively uncommon leafy green vegetables available to you. Most you can get at the produce department at your local supermarket but others you may have to grow in containers in your house or in a garden or visit a store like Whole Foods.
Leafy green vegetables include:
- Spinach
- Kale
- Broccoli
- Red and Green Leaf and Romaine Lettuce
- Cabbage
- Edible Green Leaves: dandelion, red clover, plantain, watercress, and chickweed
- Mustard greens
- Dandelion greens
- Swiss chard
- Escarole
- Turnip greens
What makes leafy greens so special?
Disease Prevention
It seems that Mother Nature knows what she’s doing, as leafy greens contain disease preventing plant-based substances that may help protect from diabetes, heart disease and even various cancer mainly because of the powerful antioxidants they offer. Kale, for example, is a great source of vitamins A C, K, calcium and also supplies folate and potassium.
Weight Loss
These vegetables have so few calories that they hardly even count and lettuce, kale and spinach can be eaten in abundance. These are also high fiber foods and so they keep you full longer and allow you to eat less. Another benefit of the fiber is that it helps to stabilize blood sugars, and that results in less out of control cravings for sweets and other junk.
Vitamin K
Different leafy greens have different properties but all of them can be considered good for you. They contain vitamin K, which is essential in helping the body to properly clot blood. Vitamin K also helps prevent several conditions related to advancing age and can help prevent bone loss, arterial calcifications, kidney damage and heart disease. Just a single cup of most leafy green vegetables will provide you with more than enough vitamin K for your system per day. Kale is especially helpful, providing about six times the recommended intake of vitamin K.
Lower Cholesterol
You can actually lower your cholesterol by eating leafy green vegetables. The bile acids produced by the liver which help fats digest from the gastrointestinal tract are bound by the fiber in the leafy greens. The bile acids pass through the body along with the residue of leafy green vegetables, forcing the liver to use up even more cholesterol to make bile acids. This reduces your endogenous cholesterol level. There was one study in the Nutrition Research journal that indicated that slightly steamed kale and mustard greens did the best job of binding bile acids.
Eye Health
Leafy green vegetables are good for the eyes. The best leafy greens to eat for eye health are mustard greens, Swiss chard, kale and dandelion greens because they are high in carotenoids such as lutein and zeaxanthin. Carotenoids help filter the high energy light caused by sun and therefore prevent sun-induced cataracts. These carotenoids also improve overall visual acuity.
Vitamin B5
A cup of raw escarole can help your body by adding pantothenic acid, also called vitamin B5. The B vitamins together help carbohydrates break down into glucose to be used for cellular fuel. The body cannot store B vitamins each day so you need to find a daily source of these vitamins. What better way than to incorporate escarole in your diet.
Calcium For Bone Health
Leafy green vegetables contain large amounts of calcium. It’s the calcium that gives these foods their slightly bitter taste. While leafy greens do not give you alone the amount of calcium you need in one day (about a thousand milligrams of calcium per day for women between 30 and 50), they provide easily absorbable kinds of calcium. A half a cup of dandelion greens will give you about 75 mg of calcium, while mustard greens can give you 55 mg calcium.
Considering that these are virtually fat-free foods they give high-fat dairy foods as a source of calcium a run for their money.
Prevent Colon Cancer
Kale and mustard greens can help prevent colon cancer by being part of the group of vegetables that includes cabbage and broccoli. In a study in one dietetic journal, those people that ate more of these leafy greens suffered a lower risk of developing colon cancer.
How do you eat leafy greens?
Leafy greens can be eaten raw in salads or can be steamed and mixed with things like herbs, other vegetables, or added to stir-fry. Generally, it is advisable to have a little heat applied to these vegetables as possible to keep their nutritional content intact. Kale and spinach both are at risk for overcooking very fast because they cook so quickly.
A good rule of thumb when cooking is to only steam to a bright free color, such as the case with broccoli, once it turns a dark green color it is likely overcooked and has lost valuable nutrients.
