What kind of diet prevent cancer?
a diet high in protein and low in carbohydrates a diet high in fiber and low in saturated fats a diet high in calcium and low in sugar

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. 

The negative effects of smoking weed underage age includes:

The answer would be true. hope this !
