There is so much garb... ahem nutrition research, that it's possible to support any possible opinion. I can't speak for the specific case, but on a general guideline, the great majority of people can reap huge benefits simply by doing sports and dropping junk/processed food. In this perspective, choosing one food [group] over another, is nothing else than bikeshedding (in other words, the bottleneck is somewhere else).
