Well I must say, eating healthy can be expensive but.....
Eating healthy doesn't have to be expensive, unless you must have organic vegetables. Prepared foods which are the highest in fat, salt and sugar cost way more per pound than unprepared foods. Restaurant food is ridiculously expensive as well as being high calorie, esp. fast food.
Oatmeal for breakfast, bean soup ((made from scratch)) with a few slices of cheese and some crackers for lunch and a 4 oz. helping of meat/poultry/fish for dinner with a salad and 1 cup of veggies is very healthy and very cheap. Snack on bananas, apples and popcorn. You can have all that for about $50/week.
