I suppose it all comes down to the era the guy is looking at in his research. If we're talking within the past 200-300 years, then the effects of colonialism certainly need to be taken into account. If we're talking about much earlier food habits, then i think England is still a reasonable example. As always, there's just so much more to the original research than the news article has room to tell us. That's one thing i'd never want to be: a science reporter. "There's so much cool stuff going on in this research, and you want me to trim it to *how* many inches?!"
