Expanding Mexicans are now fatter than Americans
Mexico has surpassed the US in levels of adult obesity, a dubious distinction that experts attribute to Mexicans abandoning their traditional diet for processed snack foods and drinks.
Almost one-third of adult Mexicans, 32.8pc, are obese compared to 31.8pc of Americans, according to the UN Food and Agriculture Organisation (FAO). Both trail such countries as Egypt, which clocks in at 34.6pc, Kuwait (42.8pc), and the Micronesian island of Nauru at 71.1pc.
Experts say the root of the problem in Mexico is changing dietary patterns.
"One factor is that Mexicans consume more soft drinks per person than any other country. That's a lot of sugar," said Katia Garcia, a nutritionist and researcher for the Power of the Consumer group.
"People have been abandoning the traditional diet, tortillas, beans and chilli, which are rich in fibre and vitamins."
The FAO's The State of Food and Agriculture report defines people over 20 years of age with a body mass index of 30 or more as obese.
A number of island nations like Samoa and Tonga also top Mexico, having more than half their populations listed as obese. Still, Mexico's obesity has caused serious concern among activists, especially given the fact that Mexico is still fighting malnutrition. Large numbers of children in Mexico's poor, rural villages remain underweight.
"Malnutrition is a paradoxical situation," said Carlos Labastida, of the general secretariat of Mexico's National Autonomous University.
"In some regions of our country, we haven't overcome the problems of a lack of calories and malnutrition, while on the other hand we have to face a huge problem, which in my opinion is even bigger than malnutrition, which is obesity and being overweight."
And the country's obesity problem is only likely to get worse. Former president Felipe Calderon announced in 2011 that Mexico had the highest rate of obesity for children ages five to 19 in the world.
Statistics show that 28pc of children between five and nine, and 38pc of pre-teens and teenagers are overweight or obese.
