Raw carrots seemed to offer the greatest amount of protection against all three types of cancer. When compared to participants who consumed a half serving of raw carrots each week, those who ate four servings of raw carrots a week were 20 percent less likely to develop breast cancer and 30 percent less likely to develop colon or rectal cancer. The researchers found that peas, bean, onions, spinach, zucchini, eggplant and peppers offered protection against colon and rectal cancer, but not breast cancer. Among the different types of fruit, only apples, pears and kiwis were associated with risk reductions of at least 5 percent for all three cancer types, the study showed. The sampling of studies mentioned above is obviously not indicative of the wealth of research that has confirmed the importance of a well-balanced diet containing a variety of fruits and vegetables.
Carrots are great, but so is broccoli and so are tomatoes.
