Eat Fruits, Veggies to Ward Off Cancer

Eat plenty of fruit and a regular diet rich in vegetables may protect against a variety of cancers, three new studies suggest.

Studies presented at the annual meeting of the American Association for Cancer Research in Los Angeles shows that fruits and vegetables that offer health benefits include apples, berries, kale, broccoli, onions, spinach and some cabbages .

The first study evaluated 183 518 men and women and found a diet high in flavonol-rich apples, berries, kale and broccoli can help reduce the risk of pancreatic cancer, especially in smokers. Flavonols are a type of antioxidant.

Pancreatic cancer is one of the deadliest of all cancers, killing 95 percent of victims within five years of diagnosis.

Another study of 500. 000 people over 50 years shows that consumption of one additional two servings of fruits and vegetables may reduce the risk of developing head and neck.

One serving equals approximately one medium sized fresh fruit, 1 / 2 cup chopped, 6 ounces of fruit juice, 1 cup leafy vegetables or 1 / 2 cup of other vegetables.

The third study suggests that chemicals in cruciferous vegetables and soy reduce production of two proteins necessary for the spread of breast cancer and ovarian cancer, reported the online edition of health magazine WebMD.

While the first study was carried out by Ute Nöthlings, DrPH, a postdoctoral fellow in the Cancer Research Center of Hawaii in Honolulu, the second study was conducted by Neal Freedman and other researchers at the National Cancer Institute.

The third study was conducted by Erin Hsu, a molecular toxicologist at the University of California, and equipment.
