Popular sweeteners may leave effects that last for generations
A study on mice suggests that common non-nutritive sweeteners like sucralose and stevia may alter gut microbiomes and gene activity in ways that persist across generations. These findings raise questions about the long-term metabolic impacts of sugar substitutes on human health.
Why it matters
As obesity and metabolic disorders remain prevalent, understanding the potential hidden health risks of widely consumed food additives is critical for public health.
Choosing the diet version of a favorite soda often means consuming non-nutritive sweeteners. These additives provide sweetness without the calories found in sugar. However, some health organizations have begun raising questions about their possible long-term effects, including whether they may disrupt energy metabolism and eventually contribute to a higher risk of diabetes or cardiovascular disease.
New research in mice adds to those concerns. The study suggests that sucralose and stevia, two widely used sweeteners, can alter the gut microbiome and gene activity in ways that may affect metabolic health. Some of these biological changes were also observed in later generations.
