 Leafy Vegetables and Nitrates
We are being encouraged to eat far more vegetables, especially dark green leafy vegetables, by virtually every agency and institution that addresses health and nutrition concerns, and there are several compelling reasons to do so.
Dark green leafy vegetables are very rich in the vitamins, ascorbic acid and betacarotene, and contain a fair amount of vitamin E. These three antioxidant vitamins plus other compounds found in plant leaves, such as indoles, flavonoids, and phenols are being shown to greatly reduce the likelihood of cancer developing.
This is largely a function of the age of the vegetable when picked and the amount of nitrate fertilizer used to grow the crop.

Vegetables and fruits are good sources of micronutrients and of several phytonutrients, which have now been shown to promote health and prevent disease.
The importance of vegetables not just from the point of view of prevention of micronutrient deficiencies but also of prevention of diseases and overall maintenance of health has not as yet been adequately recognised.

Eating plenty of fruits and vegetables can help you ward off heart disease and stroke, control blood pressure and cholesterol, prevent some types of cancer, avoid a painful intestinal ailment called diverticulitis, and guard against cataract and macular degeneration, two common causes of vision loss.
Although all fruits and vegetables likely contribute to this benefit, green leafy vegetables such as lettuce, spinach, Swiss chard, and mustard greens; cruciferous vegetables such as broccoli, cauliflower, cabbage, Brussels sprouts, bok choy, and kale; and citrus fruits such as oranges, lemons, limes, and grapefruit (and their juices) make important contributions.
Keep in mind that this is for total fruit and total vegetable consumption and that, as pointed out by the International Agency for Research on Cancer, specific fruits and vegetables may protect against specific types of cancer.
