from what i have seen briefly, top products in list of the video do not make a good balanced diet, but i could be wrong.

I see, dont take my critisim personally- i dont think thats a useful video. Whats the point of knowing most protein efficency per money spent if as end result that efficency doesnt translate to protein your body actually uses.

And if you allow me: https://en.wikipedia.org/wiki/Digestible_Indispensable_Amino_Acid_ScoreThats the start point for usefulness of proteins

Sorry, but before i watch video wanted to clarify: did you take into account protein quality? Not all protein is equal in foods, selecting highest per 100g foods wont mean you will get that amount if quality is low
