I think there is, yeah. For children anyway (and for the parents to feed them meet). People worry if they don't. I suppose it's probably different in India though.Is there really a pressure nowadays? I don't see it. In fact, every magazine runs articles against it. Some old-timers in the US have told me that in the 60s, they had to eat meat when they went out with their colleagues in order to fit in, or else they would have to go through a long process of explanation. Today, it seems to be the opposite.
With adults, probably not much. People are more like "interesting... what do you do about the protein though?".
You do have to go though a long process of explanation there usually too. Doesn't bother me though.
