Cancer is a complex disease, and it can be caused by a number of factors. Some of these factors are out of our hands, such as exposure to pollution or radiation. However, researchers have increasingly found that humans have more power over this fate than was once thought.

A study released in August 2018 put this theory to the test. Researchers in France noted that a variety of organizations around the world have released nutritional and lifestyle guidelines for optimal health. The researchers set out to find which nutritional approach best helped prevent different types of cancer, and they followed over 41,000 participants over an eight-year period.
