Frugal

I got a bag of almonds for $11. 85 grams of protein. Holy fuck. Also delicious!

I wish I could eat legumes

Y axis should be reversed. Since 90% of graphs are trying to find the sweet spot, would y the lowest-cost, highest protein be in the upper right? Unless I'm reading this correctly it's the lower right, which is hardly /dataisbeautiful

Course I'm shit at math and could be wrong...

I basically live on turkey breast, only slightly more expensive than chicken breast, but more protein and almost no fat. Makes macros super easy.

The problem is that a lot of those sources of protein aren't just protein. Take legumes; they all have a ton of carbs as well. Nuts? Loaded with fats. (Same with pork belly, TBH; that's a very fatty cut.) On the other hand, boneless, skinless chicken breast has a trivial amount of fat and carbs.

If you were plotting a 3-dimensional chart, factoring in proteins, cost, and other macronutrients, you would likely find that boneless, skinless chicken in general was the highest combination of both purity of protein, and price.
