Sweeteners Can Harm Gut Bacteria, Study Finds

Topic: Health

Scientists at the University of Cambridge tested 39 sweeteners and found that some can harm gut bacteria. The strongest effect was seen when a sweetener called isosteviol was combined with an antidepressant. More research is needed to understand the impact on human health.

Researchers at the University of Cambridge wanted to know if commonly used sweeteners affect the growth of beneficial bacteria in our guts. They tested 39 different sweeteners, including both natural and artificial ones, on 25 types of bacteria. The team found that about three-quarters of the sweeteners affected the growth of at least one type of bacteria.

The strongest effect was seen when a sweetener called isosteviol was combined with an antidepressant called duloxetine. Together, they sharply reduced the growth of two important bacterial species associated with digestive health and immune function. However, it's essential to note that these experiments were conducted in a laboratory, not on people.

The researchers also tested how sweeteners interacted with other substances commonly found in food and drinks. They paired the sweeteners with caffeine, vanilla extract, and an active ingredient in medication. The findings suggest that some sweeteners are not just harmless additives but can actually harm our gut bacteria when combined with other substances.

This study is significant because it highlights the importance of understanding how sweeteners affect our bodies. With over 100 unexpected interactions found between sweeteners and co-consumed compounds, more research is needed to determine the impact on human health.

Why It Matters

This study matters because it shows that sweeteners can have a direct impact on our gut bacteria, which play a crucial role in our overall health. As Indians, we consume many products containing sweeteners daily, and understanding their effects can help us make informed choices about our diet and lifestyle.
