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 remember seeing a youtube vid from someone who had analyzed all products from one supermarket (after scraping their website), cheapest protein ended up being flour ๐
After all people can survive on bread, on average if I remember correctly we need just 11-13% of the calories to be protein according to WHO (or less if we are eating with a caloric surplus).. protein needs are vastly exaggerated thanks to health gurus and humans' unhealthy love of meat.
Btw flour and bread are not all the same, especially refined has very little fiber and a little less protein (protein content is used also to determine quality of wheat)
