Mexico City: Mexico`s rich diet of tacos, tortillas and tortas (large sandwiches), which is jokingly nicknamed "Vitamin T," has steered its children to the top of world obesity charts.
The concerned government last week launched a new campaign to battle obesity, which it estimates to cost the health system some 3.2 billion dollars per year.
"Obesity and excess weight are one of the biggest health challenges that Mexico is facing today," President Felipe Calderon said as he introduced the national public-private plan to improve eating habits, mainly among children.
Nine-year-old Diego attends a school in a middle-class neighbourhood of Mexico City, and he said the food was healthier than it was three years ago, when there were many fried dishes made from corn.
But he added that they still sell "quesadillas" -- rolled corn pancakes filled with cheese and sometimes fried in fat -- as well as popcorn layered in butter and sugar-filled drinks.
There was only one and a half hours per week of physical exercise, he added.
"And that`s only when the teacher comes, which is not all the time, and sometimes we`re punished and we don`t go outside."
Calderon admitted that Mexico had the highest amount of overweight adults in the world, which means a Body Mass Index (a statistical measure that compares weight and height) of more than 25.
Its children had the highest rates in the world for obesity, which means a BMI of more than 30.
The president deplored that Mexico spent 3.24 billion dollars to treat illnesses linked to excess weight and obesity in 2009, such as diabetes, which is the number one cause of death in the country.
The new plan is based on a French project known as EPODE, which has shown success at reducing child obesity through physical activities, weight monitoring and promoting drinking water and eating fruit and vegetables.
Food and drink advertising in Mexico is already supposed to promote healthy eating and exercise, but the requirement is often ignored.
And the battle against obesity is not easy here, where street vendors outside schools across the country sell vast selections of brightly-coloured sweets and enticing fried foods.
