BANGKOK: For many Thais, a meal doesn’t feel complete without an iced coffee or tea so sugary it could pass for dessert. The government, concerned about the health consequences, wants them to dial it back.

Starting Wednesday, nine major coffee chains across the country have pledged to cut the default sugar content in some of their drinks by half in a government initiative aimed at tackling excessive sugar consumption.

According to the Health Department, Thais consume an average of 21 teaspoons of sugar per day, more than three times the World Health Organization’s recommended limit of six teaspoons. Health officials warn that such high intake increases the risk of obesity, diabetes and other diseases.

The initiative is the first significant step to change consumers’ sugar consumption behavior, said Amporn Benjaponpitak, the director general of the department.

Pakorn Tungkasereerak, the department’s deputy, said 2025 data show that about 45 percent of Thais aged 15 and older are obese, while 10 percent of the population has diabetes.
