Mexicans are the biggest consumers of surgery drinks in the world. But the country’s sugar obsession is causing what health officials are calling a diabetes emergency.

In some poor towns across the country, Coca-Cola is even more available than fresh water. 

Our reporter, Guillermos Galdos went to Chiapas for Unreported World, the poorest state in Mexico, where people drink on average two litres of sugary drinks a day, and Coca-Cola is King. 

He met the families in the thick of a diabetes crisis and also encountered people who in fact use Coca-Cola to treat illnesses, believing the drink has special healing powers. 

So why are fizzy drinks so popular in this part of the world and what will happen if the sugar epidemic continues?
