Still, the study is interesting, particularly in light of another paper published this week in the journal PLoS Medicine. As part of that journal's excellent series on "Big Food" and its impact on the world's health, two Brazilian epidemiologists, Carlos Monteiro and Geoffrey Cannon, describe how their country is trying to protect its traditional food system from the ultra-processed products made by transnational food corporations... Right now, the prevalence of diabetes in Brazil is 5.2 percent, half of what it is in the U.S. or Singapore. But that number is climbing, especially in Brazil's cities.
