To ensure the greatest nutritional benfits, dietary guidelines suggest wich of the following? a)cooking food thoroughly. b)eating nutrient-dense foods. c)eliminating all snacks from a diet. d)washing foods before eating them

D is the answer. Because its the best answer. And because its more healthy to wash your hands before eating because it could have germs or dirt(be dirty) and when you wash them they will be clean but if you didn't your food will get germs and then eat that food and get germs in body then be sick. I hope this helps!
