I see this opinion all the time. It is not correct. Whole grain products, fresh whole chickens and frozen vegetables are less expensive than the sugary or process foods you talk about and do not lead to negative health outcomes. Choosing unhealthy food is not a financial decision. Marketing, laziness and ignorance are what drives poor food choices. Buy a crock pot and a crock pot cookbook. Eat delicious healthy food for very little money and very little time and effort. A wonderful meal will be waiting for you when you get home with enough left over to eat for lunch the next day. Rinse and repeat with different ingredients.
