A new mechanism reducing sugar cravings discovered

Researchers at Stony Brook University have made a sensational discovery: neurosteroids - special brain molecules known for their effects on mood and stress resistance - can significantly alter the perception of sweet taste. The results of this breakthrough study were published in the prestigious scientific journal Nature.

During the experiment, scientists conducted a series of unique tests using the neurosteroid allopregnanolone. When this substance was introduced into the taste cortex of test mice, a striking effect was observed: the rodents not only lost interest in sweet water but also showed a significant decrease in their ability to distinguish its taste. Even more impressive results were obtained when blocking gamma-aminobutyric acid receptors - the mice completely lost their ability to distinguish sweet water from regular water.

This discovery could become a real breakthrough in the fight against obesity and eating disorders. Researchers emphasize that reduced sensitivity to sweetness may trigger overeating and weight gain, and this new understanding of these mechanisms opens promising perspectives in developing innovative methods for appetite control.

Currently, the research team continues their studies, aiming to determine whether the discovered mechanism extends to the perception of other taste sensations.
