But I loved it. Also this has Shrimp removed, because it was on the OG chart due to an error and this is an updated version.
EDIT: Here is one for protein! https://www.reddit.com/r/budgetfood/comments/1fp2ytb/foods_cost_per_gram_of_protein_vs_protein_density/#lightbox
Well we can easily check! It says they used Walmart.
Here's the cheapest per ounce I see for tuna:
https://www.walmart.com/ip/Great-Value-Chunk-Light-Tuna-in-Water-5-oz-4-Pack/33867594?classType=VARIANT&athbdg=L1200&from=/search
It's 3.22 for 400 calories, so one dollar gets you 124 calories of tuna.
Then cheapest wings I see at $3 a pound, and have 4,840 calories for 24 dollars, coming out to 200 calories per dollar:

So for me doing the math JUST off packaging (he appears to use a nutritional calculator) it's coming up chicken wings is cheaper source of calories.
So it's possible in this persons state their chicken was slightly cheaper, and they didn't have the generic tuna. But even in my state where chicken costs a little bit more than what is listed, and my tuna costs a little less, chicken wings are still close to 50% cheaper for calories.
I wonder if it's just a "Feeling" thing, because a little can of tuna is just a dollar! That must be cheap, right?... but a can of tuna is 100 calories, which isn't a great deal.
