Thailand's Sweet Dilemma: Can a Nation Change Its Taste?

At her bustling Bangkok stall, Auntie Nid, 68, crafts her famous iced Thai tea with a generous hand, pouring condensed milk and three heaped spoons of sugar into each glass. "I want to spoil my customers," she says, as a queue snakes out the door. Her recipe, unchanged for 30 years, embodies a national preference. Yet, the Thai government is now challenging that very sweetness.

This month, a new health initiative secured commitments from nine major coffee chains to slash the sugar in their standard recipes by half for select beverages. The goal is to recalibrate the national palate. On average, Thais consume 21 teaspoons of sugar daily, more than triple the World Health Organization's advised limit, with sugary drinks a primary source.

Previous measures, like a tax on pre-packaged drinks introduced in 2017, spurred manufacturers to reformulate products. "That tax led many companies to lower sugar levels to avoid higher rates," notes Assistant Professor Pojjana Hunchangsith of Mahidol University. However, the vibrant world of street vendors and cafes, offering everything from boba tea to pink milk, remains largely untouched by regulation.

The latest campaign focuses on cafes where sweetness-level cards are already common. Now, for some drinks, the "100% sweet" option will contain half its former sugar. Research supports this subtle shift. A study by Khon Kaen University's Associate Professor Phumsith Mahasuweerachai found that simply presenting sweetness choices prompts customers to pick less sugar; calorie labels had less effect.

Public reaction is mixed. Bangkok taxi driver Ann Thumthong, 55, welcomes the change, noting the difficulty of finding unsweetened options. She has personally shifted from desserts to fruit. But at Auntie Nid's stall, the sentiment is different. Customer Phakamas, 39, enjoys an occasional sweet treat, while Auntie Nid herself is adamant. "No, no, no," she insists. "Without sugar, the coffee and tea will be bland and bitter." As Thailand tries to turn down the volume on sugar, its success hinges on convincing a nation, one cup at a time.
