A long time ago a bakery in the UK advertised that bread provided something like 70% (or more) of the daily protein for an average person these adverts were withdrawn because not all protein is good for you and many act as carbohydrates...then we had vegetarians saying there was easily enough protein in vegetables...we did not need meat or fish....and most recently we have chefs on TV referring to "protein" as somehow meaning only meat and fish any vegetable, bean or pulse on the plate doesn't count they cannot ALL be right?...so who is telling the truth?
