[Correspondence] Tackling obesity: challenges ahead

The Lancet Series on obesity missed an important opportunity to more fully address non-Western food and the implications for policy and consumer engagement. While citing a few low-income and middle-income country examples, and noting the need for sociocultural dimensions in policy, the Series seemed more oriented to the Americas, in particular the USA, and other western perspectives, than to the experiences and needs of the great majority of the world’s population. Now that diet has been shown to be a more important factor associated with disease burden than physical inactivity or high body-mass index,1 a culturally-grounded, comprehensive approach to the global challenge of poor diet would seem called for.
