Best Diet To Prevent Cancer


Research has shown that a healthy diet can lower your risk of certain cancers. It also may help prevent other conditions, such as type 2 diabetes, osteoporosis, and heart disease.
One benefit of good nutrition is that it helps you maintain a healthy weight. People who are overweight or obese are at risk of more health problems. A high-fibre, low-fat diet and regular exercise can help you lose weight and keep it off.

Can certain dietary choices reduce my risk of cancer?
