E957 Thaumatin

What is Thaumatin (E957)?

Thaumatin, designated as E957, is a natural sweetener derived from the katemfe fruit, native to West Africa. It is known for its intense sweetness—estimated to be about 2000 to 3000 times sweeter than sucrose—while contributing negligible calories. Thaumatin is often used in food and beverage products, including soft drinks, chewing gum, and desserts. It also has flavor-enhancing properties, making it a popular ingredient in various formulations.

Why do I have an intolerance?

Intolerance to thaumatin can manifest as gastrointestinal discomfort, bloating, or other digestive issues. Although rare, some individuals may experience sensitivity due to the body’s reaction to this natural protein. The mechanisms behind such intolerance can include the body's inability to properly break down proteins, leading to adverse reactions. Additionally, individuals with specific dietary restrictions or allergies may be sensitive to thaumatin, as it is derived from a plant source that may trigger reactions in predisposed individuals.

What can I do about it?

If you suspect an intolerance to thaumatin, the first step is to eliminate it from your diet and observe if symptoms improve. Reading food labels carefully will help you avoid products containing E957. Opting for alternative sweeteners that do not trigger adverse reactions can also be beneficial. In cases where sweeteners are essential, exploring other natural or synthetic alternatives can help maintain a balanced diet without compromising taste.
