For all the grievances people made against food pyramid, this is actually the real reason why it was instituted. Meat has always been expensive, and with limited money people had, they'd rather spend it all on grains and save the money for something else. Food pyramid encourages people to at least add some proteins in their diet. And it works, people's height had been increasing decade-by-decade.

In a way, the movement to disparage food pyramid because it institutes too much grain really seems like a first world problem. Especially any that encourages more meat.
