Vietnam cautions on excessive tamarind drink consumption

Tamarind drink (nước sấu ngâm) is a popular summer beverage in Vietnam, praised for its refreshing sour‑sweet taste and its content of organic acids, vitamin C, iron and natural electrolytes. It is widely sold by street vendors and prepared at home to quickly relieve thirst and replenish lost minerals.

Health experts warn that the drink’s high sugar and acid levels can become harmful when consumed improperly. Drinking large quantities—often two to three glasses daily—adds a substantial amount of liquid sugar, forcing the pancreas to overproduce insulin and increasing the risk of insulin resistance, obesity and type 2 diabetes. Consuming the drink on an empty stomach exposes the stomach lining to concentrated acids, potentially causing irritation, erosion and persistent upper‑abdominal pain.

To avoid these risks, advice includes limiting intake, avoiding it as a water substitute, and refraining from drinking it on an empty stomach. Moderation and balanced preparation are recommended to retain its cooling benefits without compromising health.
