Diet drinks often contain a mix of sweeteners that enter the bloodstream after consumption. As the current pilot study shows, sweeteners don't just affect the taste buds.
Sweeteners are substitutes that have a very high level of sweetness but have little or no impact on energy intake. Not only in the USA, but also in Germany, they play an important role - especially for people who love sweets but want to save calories and sugar. But sweeteners don't just affect the taste buds in the mouth. Recent studies show that they also affect the human immune system, although the underlying molecular relationships are still poorly understood.
