It's definitely more economical to buy lots of food in bulk. It also helps to have lots of refrigerator and other food storage space. Unfortunately, buying in bulk isn't going to be an option for many single people with lower incomes and not much refrigerator/storage space... (maybe with the exception of beans and rice, which can be stored relatively compactly and for a long time without refrigeration). Another thing that works against people with lower incomes is that much of the nutrious food is more expensive than the less nutritious food. Bread is a prime example. The cheapest bread is highly processed white bread. The more nutrious whole, multi-grain breads are usually two or three times as expensive as the cheap crap. Same with organic, cage- and cruelty-free produce vs the pesticide-ridden crap.
