cooking with my family - make up questions

Dinner at home is fast and easy because we always eat out and some times cook. My favorite food we cook is steak and rice with corn. My family thinks healthy food  is good but we like fast food more and i think Americans eat fast food more then cooking because its faster then cooking and there probably lazy or busy. I think fast food is what starts obesity because they use allot of fattening things in the food and people east put a lot  if i cooked it would be healthier because i would cook healthy.
