Going to the movies, going to the gym, biking etc.
Fats I am pretty sure. Sorry if I am incorrect.
I think the diet that helps prevent cancer is a diet high in calcium and low in sugar because if it was a diet high in protein u would have diabetes and other bad things. And if it was a diet high n fiber and low in saturated fat it wouldn't be low it would be really high and would probably have cancer that is why I a say c. the last one.
