YES! When I became vegetarian I wanted to do it responsibly so I tried to google all the information about proteins. I have learn that there like 8 types of proteins that human body don't produce and we need them from the outside source, usually that source beeing animal meat. So I tried to find any informtions about suplementation of those specific proteins in plant based diet but I field. Now I just eggs as a way to suplement but curiosity sometimes bugs me to this day.
