It's interesting that overall spending doesn't decrease that much in the end, although shifting from snacks to fruit is the kind of change health advocates have always wanted?
Most Little Debbie varieties, for a standard package containing 6 or 12 items depending on the size of the items, are listed at $3.19.
Apples are commonly sold in 3 pound bags, which the internet suggests would contain 6-12 apples depending on the variety of apple and individual sizing. The 3 pound bag seems like a reasonable comparison to the standard Little Debbie packages, as it's 6-12 "snacks" in either case.
The cheapest option is Red Delicious at $3.99. You can spend up to $6.99 for 3 pounds of a more premium variety.
Little Debbies cost $0.26 to $0.53 per snack. Cheap apples are $0.33 to $0.66 per.
The advantage is also present with larger quantities. A large package of Little Debbie snacks costs $5.49, and a 5lb bag of Red Delicious apples costs $5.99. You're getting 2x the Little Debbie snacks in the larger package, but you're only getting 66% more apples in a 5lb bag.
At the larger quantity, LD's per snack price range is $0.23 to $0.45. Red Delicious apples are $0.30 to $0.60.
Either way people should be eating apples, bananas, pears (as well as cheese, nuts...), instead of snack cakes.
- It's extremely unlikely that any of the snack cakes in a particular box on the shelf have gone bad or have rotten areas. They must carefully inspect a bag of apples for brown spots or risk getting less usable product than they paid for.
- The snack cakes can sit at home for a really long time and still be usable. The apples have a much shorter shelf life. This makes bulk pricing more attractive for the snack cakes as there's a better chance all of the product can be used before it goes bad.
- The apples require more preparation, dependent on preferences. Yes, you can grab an apple out of the bag and chow down. A lot of folks will want to wash it first. Some will want to cut it into pieces, or peel it, or do some other prep to it before eating. Snack cakes are pretty much always eaten as they are.
Add it all up and it starts to become clearer why a lot of economically disadvantaged folks end up making "bad" choices around food. All of these points could be mitigated in various ways, but generally they would increase the financial and/or time costs.
