The Thai government is urging coffee chains to cut sugar in drinks by half to combat health issues. Starting Wednesday, nine major chains will reduce sugar in some beverages. The Health Department says Thais consume 21 teaspoons of sugar daily, far exceeding the World Health Organization's recommended six teaspoons. Officials warn this increases obesity and diabetes risks. A survey found iced coffee and bubble tea contain high sugar levels. Some customers welcome the change. Brands can apply the initiative as they see fit, which may complicate implementation.
