Green Leafy Vegetables - Nutritional Powerhouses

Eat Your Greens!

A nutrition professor once told me that it was common for our ancient ancestors to eat up to six pounds of leaves per day. He imagined them walking along from one place to another, just picking and eating leaves as they went. Can you imagine eating a grocery bag full of greens each and every day? Few of us even eat the minimum USDA recommendations of 3 cups of dark green vegetables per week. And yet, these veggies deliver a bonanza of vitamins, minerals, and phytonutrients.

Health Benefits

Dark green leafy vegetables are, calorie for calorie, perhaps the most concentrated source of nutrition of any food. They are a rich source of minerals (including iron, calcium, potassium, and magnesium) and vitamins, including vitamins K, C, E, and many of the B vitamins. They also provide a variety of phytonutrients including beta-carotene, lutein, and zeaxanthin, which protect our cells from damage and our eyes from age-related problems, among many other effects. Dark green leaves even contain small amounts of Omega-3 fats.

Perhaps the star of these nutrients is Vitamin K. A cup of most cooked greens provides at least nine times the minimum recommended intake of Vitamin K, and even a couple of cups of dark salad greens usually provide the minimum all on their own. Recent research has provided evidence that this vitamin may be even more important than we once thought (the current minimum may not be optimal), and many people do not get enough of it.
