CRAVING FOR SWEETS New Delhi, May 3: A hormone made inside the liver may hold the key to the human sweet tooth. Their study, published yesterday in the journal Cell Metabolism, also suggests for the first time that the liver, through the FGF21 hormone, may control human eating behaviour. "We're now a step closer to understanding the molecular basis of the sweet tooth - something that has not been well understood," Matthew Gillum, assistant professor of biological sciences at the university, told The Telegraph. Those who disliked sweets had fasting FGF21 levels higher than those who liked sweets. These observations suggest FGF21 may be a "negative regulator" of sweet consumption because the hormone increased markedly after the oral sugar intake and because those who dislike sweets have higher FGF21 levels than those who like.
