Frequently eating apples can reduce the risk of developing bowel cancer. According to a recent report in the UK's Daily Mail, a trial has shown that eating more than one apple a day can reduce the risk of bowel cancer by about half, while eating other fruits or vegetables did not show the same effect. Researchers believe that the protective properties of apples may be the result of their high content of flavonoids. These antioxidants, found in apple skins, can prevent free radicals from causing damage to molecules or tissues, thereby inhibiting the occurrence of cancer and cell proliferation. And the antioxidants in the apple skin are 5 times higher than in the flesh, so when you eat apples, you can wash them, but don't peel them.
However, the World Cancer Research Foundation states that the risk of all cancers can actually be reduced by 30%-40% through simple lifestyle changes, such as eating more fruits and vegetables, exercising regularly, and controlling weight.
