1. Soy, brown rice, pea, corn, and potato all hit their EAA/total protein cut-off.
2. I don't see how amino acid % of total protein is a useful way to gauge a food's protein especially in this context. Wouldn't you want to look at protein per calorie or EAA per calorie?
For example the paper's chart might make you think that you should eat potatoes and corn if you want to maximize plant-based protein, but that's not the case at all.
- 500 calories of potatoes boiled: 10g protein (650g of food)
- 500 calories of rib-eye steak: 54g protein (200g of food)
- 500 calories of soy chunks (TVP): 75g protein (btw hits all EAA objectives for the day) (150g of food)
- 500 calories of wheat gluten (seitan): 101g protein (135g of food)
Potatoes are dense in other nutrients and a great part of a healthy diet, but you definitely wouldn't use potatoes as a "meat protein substitute". Even broccoli is 3x as protein dense as potatoes.
On the other hand, seitan, tofu, and TVP are the trifecta of plant-based protein that can actually substitute for meat.

PDCAAS is a reasonable standard to use, pro-rated against total calories. https://en.m.wikipedia.org/wiki/Protein_Digestibility_Corrected_Amino_Acid_Score https://en.m.wikipedia.org/wiki/Protein_Digestibility_Correc...
- hombre_fatal 3y agoOne problem with PDCAAS is that it's based on the limiting EAA in a food, but everyone interprets it as a general bioavailability ratio when it's not. A food with 1000x the EAAs per calorie of every other food, but 0 of one EAA would score below the other foods even though you could get the day's worth of EAA on 1/1000 the calories + one serving of an additional food that can give you the missing EAA (i.e. eat more than one food every day).
- graphe 3y agoDon't compare whole potato, it should be to potato protein extract.
- hombre_fatal 3y agoIf you were just talking about min-maxing protein extracts for a protein powder or something, I wouldn't have commented. But your comment on the EAA/totalProtein ratio (when potatoes are very low in protein) possibly being responsible for why potatoes taste good made me chime in for clarification.
