Read the article again, with a critical eye. For one thing, people are talking about "organic" in it. Food does not have to be certified "organic" to be healthy, in fact "organic" is mostly a marketing gimmick these days. But "organic" can be much much more expensive.

Thats just one criticism. The article has no data period, just a few people talking about their feelings basically. Though some of the people featured do admit that by paying attention, they can in fact eat healthy on a low budget.
