Cancer is a complex disease as is the relationship between diet and lifestyle in disease prevention. We do know that eating lots of red meat increase one's risk for developing colorectal cancer, and that obesity affects breast cancer risk. And let's be clear, this study is by no means an excuse to eat less produce, since a diet high in vegetable matter can help lower blood pressure and blood sugar, thereby reducing the risk for developing type 2 diabetes. Plus, fruits and veggies provide necessary nutrition for the body regardless of their cancer fighting properties, and they help in weight loss by increasing the feeling of satiety so we consume fewer calories.
Eating right is an essential part of a healthy lifestyle. To reduce your risk of cancer, don't smoke, keep your alcohol consumption to a minimum, and exercise regularly.
