What are antioxidants and how do they work? Here’s the latest buzz on berries and other foods rich in antioxidants.

Antioxidants are plant substances that protect our cells from damage caused by free radicals, which are unstable and highly reactive molecules. Free radicals damage cells by altering their chemical structure. They become less destructive, however, when they interact with antioxidants first.

Since all cancers develop in the cells, scientists believe that antioxidants may slow down or prevent cell damage. Since the evidence is not conclusive, taking supplements high in antioxidants (such as vitamins A, C and E) is not recommended for preventing or treating cancer.
