I've heard that some foods can cause cancer. Is there any truth to this?

It is true that certain foods may contain substances that are known carcinogens, such as nitrosamines and aflatoxins. However, these compounds are found in very small amounts, so they would have to be consumed in large quantities for them to pose a health risk. In general, the best way to reduce your risk of developing cancer is to follow a healthy diet rich in fruits, vegetables, whole grains, and lean proteins.
