Is there more to the question, like multiple choice questions? Budget can have an influence on food choices. If someone has a small budget, they may need to buy less expensive, filling foods. Family can have an influence on food choices. If someone is surrounded by people who consume healthier foods, and have nutritious choices available, they are more likely to eat better as well. Then there's advertising. Too many junk food ads can trigger cravings for the less healthy snacks. For instance, if someone is watching t.v., and they see a pizza ad, but there is salad in the fridge, they may think "oh, pizza sounds great!" and just order delivery. It would be easier to have something already made come to your door, vs getting in the kitchen and creating a mess to make ones own salad.
