Thailand's Sugar Reduction Drive Faces Resistance from Street Vendors
In the bustling old town of Bangkok, Auntie Nid has been serving her signature iced Thai tea for three decades. Her recipe is a beloved tradition: three heaped tablespoons of sugar mixed with condensed milk and freshly strained tea, poured over ice in a plastic bag. "I want to spoil my customers," says the 68-year-old vendor, who cannot fathom altering her formula. However, the Thai government is determined to reduce sugar consumption nationwide, launching a health campaign that major coffee chains have joined, though street vendors remain outside regulatory reach.
Government Initiatives and Major Chain Commitments
This month, nine of Thailand's largest coffee chains agreed to halve the default sweetness in some beverages as part of a public health drive. The campaign aims to reset taste preferences, addressing the fact that Thais consume an average of 21 teaspoons of sugar daily—far exceeding the World Health Organization's recommended limit of six teaspoons. Sugary drinks are a primary contributor, with Thailand historically ranking among Asia's top consumers of calories from sweetened beverages.
Thailand has previously implemented measures like a sugar tax, introduced gradually from 2017 and fully rolled out last year, targeting pre-packaged drinks. According to Pojjana Hunchangsith, assistant professor at Mahidol University, the tax has spurred product reformulation, as manufacturers lower sugar levels to avoid higher rates. However, this tax does not apply to street vendors or cafes, where menus feature an array of sweet options like boba milk teas, iced cocoa, and pink milk. Pojjana notes these outlets are significant sugar sources but are harder to regulate due to their fresh-made nature.
Customer Perspectives and Behavioral Nudges
Under the new initiative, major cafe chains will adjust their sweetness scales. Many shops already display cards offering sweetness levels from 0% to 100%; for certain drinks, 100% sweetness will now be half as sugary. Ann Thumthong, a 55-year-old Bangkok taxi driver, welcomes these changes, noting the difficulty of avoiding sugar in food and drinks. She has become more health-conscious with age, swapping desserts for fruits and believes taste preferences can be retrained to require less sugar.
Phumsith Mahasuweerachai, an associate professor at Khon Kaen University, emphasizes the power of simple adjustments. His research found that giving customers the choice of sweetness levels prompts them to opt for less sugary drinks, whereas providing calorie information has little impact. "If we don't nudge customers or prompt them, it's difficult for them to make the change," he explains. "They go to the coffee shop and it's automatic."
Street Vendor Resistance and Cultural Significance
At Auntie Nid's shop, customer Phakamas, 39, enjoys an iced cocoa during her lunch break, viewing occasional sugar consumption as acceptable. However, Auntie Nid remains steadfast in her refusal to modify recipes. "No, no, no," she insists, as a queue of tourists, local workers, and students extends out the door. Her shop, popular for years, has gained fame among foreign visitors through social media. She argues that sugar is essential for the intense flavor of her drinks, claiming that without it, coffee and tea would be bland and bitter.
This resistance highlights a cultural clash between public health goals and traditional practices. While government efforts focus on reducing sugar intake to combat health issues, vendors like Auntie Nid see their recipes as integral to Thai culinary identity. The challenge lies in balancing these perspectives to achieve meaningful change without eroding cultural heritage.
