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
I'm calling BS on tuna being more expensive than chix wings...depends on grade of tuna. Wings are expensive AF!
Idk what their source was but I think you should look for cheapest "possible" to do a fair comparison (cause obviously a certain shop can have super expensive wings). Near me lowest for wings will be 3-5€/kg, canned tuna starts from 8/kg when on discount, but also has like 30% of seed or olive oil in it (so actual tuna cost to the consumer is more like 12€/kg minimum) Chicken is definitely cheaper everywhere IME.
BTW I'm talking raw chicken wings..everything pre-cooked costs more
