A new six-month trial suggests that changing how much sweet-tasting food people eat does not alter how much they enjoy sweetness. Researchers also found no meaningful differences in several measures related to heart disease and diabetes risk among people who ate diets with high, low, or average levels of sweetness.
The findings raise questions about public health advice that encourages people to reduce sweet-tasting foods as a way to combat overweight and obesity. The researchers argue that the more important targets may be sugar intake and energy-dense foods rather than sweetness itself.
Sweetness Intake Did Not Change Taste Preferences
The study was conducted by researchers at Wageningen University and Research in the Netherlands and Bournemouth University in the UK. The findings were published in the American Journal of Clinical Nutrition.
"People have a natural love of sweet taste which has led many organizations, including the World Health Organization, to offer dietary advice on reducing the amount of sweetness in our diets altogether," said Katherine Appleton, Professor in Psychology at Bournemouth University and corresponding author for the study. "However, our results do not support this advice, which does not consider whether the sweet taste comes from sugar, low-calorie sweeteners, or natural sources," she added.
