<human>: I've heard that a certain food can help prevent cancer. Is this true?
<bot>: Yes, it is true that some foods have been linked to lower rates of cancer. Foods such as cruciferous vegetables and fruits like berries and citrus fruits are high in antioxidants which may help reduce the risk of developing cancer.
