Live healthy with Green Leafy Vegetables


Mother was right all along. Grandma also told you they were good for you. So why do Americans eat green leafy vegetables only about once or twice a week? Why are cabbage, broccoli, turnip greens, and spinach rarely seen at the American dinner table? Why is lettuce the only green vegetable that most Americans ever use, when green vegetables are recognized by nutritionists as one of the most inexpensive sources of so many important nutrients?
Leafy vegetables are ideal for weight management as they are typically low in calories. They are useful in reducing the risk of cancer and heart disease since they are low in fat, high in dietary fiber, and rich in folic acid, vitamin C, potassium and magnesium, as well as containing a host of phytochemicals, such as lutein, beta-cryptoxanthin, zeaxanthin, and beta-carotene. One study showed that an increment of one daily serving of green leafy vegetables, lowered the risk of cardiovascular disease by 11 percent. In the Adventist health study, the frequent consumption of green salads by African-Americans was associated with a substantially lower risk of mortality.
Because of their high magnesium content and low glycemic index, green leafy vegetables are also valuable for persons with type 2 diabetes. An increase of 1 serving/day of green leafy vegetables was associated with a 9 percent lower risk of diabetes. The high level of vitamin K in greens makes them important for the production of osteocalcin, a protein essential for bone health. The risk of hip fracture in middle-aged women was decreased 45% for one or more servings/day of green, leafy vegetables compared to fewer servings.
Green vegetables are also a major source of iron and calcium for any diet. Swiss chard and spinach are not considered good sources of calcium, due to their high content of oxalic acid. Green leafy vegetables are rich in beta-carotene, which can also be converted into vitamin A, and also improve immune function. Millions of children around the world have an increased risk of blindness, and other illnesses because of inadequate dietary vitamin A from green leafy vegetables.
Lutein and zeaxanthin, carotenoids found in dark-green leafy vegetables, are concentrated in the eye lens and macular region of the retina, and play a protective role in the eye. They protect against both cataract and age-related macular degeneration, the major cause of blindness in the elderly. Some studies suggest that lutein and zeaxanthin may help reduce the risk of certain types of cancer, such as breast and lung cancer, and may contribute to the prevention of heart disease and stroke.

So have more and more Green Vegetables in your diet....and stay Naturally
