Cancer and its prevention by some horticultural and field crops in Turkey.

Diet is considered to play an important role in the etiology of carcinogenesis, and almost 30 % of cancer development is known to have a dietary background. Many diets appear to contain groups of food components that can prevent, slow down, or even reverse carcinogenesis. In the present commentary, discussion is focused on the following crops: almonds, apricots, plums, peaches and nectarines, cherries, pears, figs, chestnuts, hazelnuts, pistachios, walnuts, grapes, strawberries, avocados, bananas, olives, lemons and limes, oranges (tangerines, mandarins, clemetines, satsuma), grapefruit and pomelons, artichokes, potatoes, green beans, carrots, cabbages, melons, watermelons, pumpkins, cucumbers, garlic, cauliflower, peppers, eggplants, tomatoes, onions, dry bean, soybeans, maize, barley, wheat, rye, and lentils. According to results some of epidemiology, numbers of horticultural and field crops of Turkey are likely to be associated with reduced risk of different cancers. Associations with protection in individual cases are here reviewed.
