I dunno what Google you're using but it took me half a minute to get to multiple sources suggesting vegetarians are on average healthier, have lower BMI, lower incidents of common cancers and more. Obviously balance probably trumps everything as it always does but there's imo fairly compelling evidence in the non meat direction, on average, for most people.

But once again may I stress that for me it's a whole range of factors that make this compelling, not just one.
