A dietitian’s ranking of 12 popular breakfast-shop drinks highlights sharp differences in carbohydrate content, with rice milk emerging as a surprising outlier.
Breakfast drinks are often treated as an afterthought, but the wrong choice can push carbohydrate intake much higher than expected. A recent report in Liberty Times Health, drawing on advice from dietitian Hsiao Wei-lin, ranked 12 common breakfast-shop drinks by their carbohydrate content and found wide differences between the most blood-sugar-friendly options and the biggest outliers.
At the low end of the list were unsweetened green tea, black coffee, unsweetened soy milk, unsweetened milk tea, unsweetened black soy milk, low-fat milk and a whole-milk latte. Hsiao said these drinks each contain 15 grams of carbohydrate or less per serving, making them relatively modest choices for people trying to keep blood sugar steady. The report noted that unsweetened soy milk and black soy milk also add useful protein, while low-fat milk and latte drinks derive much of their carbohydrate from lactose, the natural sugar in milk.
The most striking example of how quickly a drink can shift from light to heavy is rice milk. According to the Liberty Times report, a medium cup contains 37 grams of carbohydrate, far more than sweetened soy milk at about 20 grams. That matters because carbohydrate in liquid form is absorbed quickly and can produce a sharper rise in blood glucose than food that takes longer to digest. The comparison also shows why serving size matters: a ready-to-drink orange breakfast beverage listed by University Hospitals contains 33.4 grams of carbohydrate in a single 8-ounce serving, underlining how easily seemingly benign drinks can become sugar-dense.
The middle of Hsiao’s ranking included full-milk lattes, sweetened soy milk, oat milk and matcha lattes, which all land well above the lowest group. That mirrors broader nutrition guidance, which often warns that many breakfast beverages contain fast-digesting sugars and little fibre to slow absorption. Hsiao also pointed to a separate body of research suggesting that a high-protein breakfast can help reduce hunger later in the morning and cut cravings in the afternoon, an effect that may make it easier to avoid overeating at lunch or reaching for high-calorie snacks. In practical terms, the message is simple: if blood sugar control matters, choose drinks with little or no added sugar, and treat sweeter breakfast beverages as occasional rather than automatic choices.
