Brazilians have earned a reputation around the world for their beauty, boosted by fashion icons like Gisele Bündchen. But a recent article from the Science and Development Network sounded an alarm about the state of things in Brazil. Jonathan Wells, a reader in childhood nutrition at the UCL Institute of Child Health in London, commented on the alarming growth of obesity in Bündchen's homeland:
In Brazil, between 1973 and 1996, obesity increased from 2.4 to 6.9 per cent in men and from 7.0 to 12.5 per cent in women. In simple terms, obesity arises when people consume more energy than they expend, either by eating too much or exercising too little.
It may seem strange to sound an alarm about obesity while so much attention is being directed at rising food prices. (See, for example, this piece by Martin Wolf.) Obesity, however, is a serious problem in many middle-income countries, perhaps outstripping the number of undernourished individuals. A slightly dated article in Foreign Policy suggests that China, Mexico, Brazil, and Togo all have higher rates of obesity than undernourishment.
While higher food prices may put a dent in this trend, that's not entirely clear in advance. It will depend on how individuals at risk for obesity respond to price changes - and they may opt for cheaper, less healthier food if that's what is available. So what should be done about this serious health threat?
