Adults who spent six months eating diets deliberately high, low, or average in sweetness ended the trial liking sweet tastes about as much as they had at the start, according to a randomized controlled trial that tested a widely repeated assumption behind public health advice.
The Sweet Tooth Trial, conducted by researchers at Wageningen University and Research in the Netherlands and Bournemouth University in the United Kingdom, assigned 180 healthy adults to three groups. The results appeared in the American Journal of Clinical Nutrition and have circulated repeatedly through science news outlets since.
