It has been said that the greening of the diet may be much more important to survival than the greening of the planet! Green vegetables are packed with a variety of compounds, ie carotenoids, cholrophyll, glutathione, folic acid, vitamin C, etc that are known to protect our cells from a whole list of damages. So be sure you include green vegetables in your diet daily. That doesn't mean you have to sit down and eat a bowl of greens everyday. Toss some greens into soups, stir-frys, etc. And a few salads a week is a good idea.
As an example we will look at cabbage which along with its other cruciferous kin such as kale, cauliflower, broccoli, Brussels sprouts, bok choy, etc, is extremely high in phytochemicals which are great protectors from cancer, etc. Cabbage also works as an anti-inflammatory and antibacterial. One of the properties of cabbage and its kin is indole-3-carbinol, known as IC3 for short. IC3 nearly doubles how quickly the liver can break down estrogen so it doesn't remain in the body. (Estrogen is known to feed some cancers.) Do not overcook as you will lose some of the important chemicals in doing so.
