Cutting sweet foods doesn’t curb cravings or improve health

A recent six-month study conducted by researchers at Wageningen University and Research in the Netherlands and Bournemouth University in the UK has found that altering the amount of sweet-tasting foods consumed does not affect an individual's enjoyment of sweetness or their health markers related to heart disease and diabetes risk.

The study, published in the American Journal of Clinical Nutrition, challenges the common public health advice to reduce sweet-tasting foods as a means to combat overweight and obesity. The researchers recruited 180 participants and divided them into three groups, each consuming diets with high, low, or average levels of sweetness.

The sweetness in the foods came from various sources, including sugar, natural sweetness, and low-calorie sweeteners. After three months and six months of the trial, the researchers found no significant differences among the groups in terms of their preference for sweetness, body weight, or health markers. The study's corresponding author, Professor Katherine Appleton from Bournemouth University, emphasized that the study does not support the notion that reducing sweetness in the diet is beneficial for weight management or overall health.

The researchers argue that the focus should be on sugar intake and energy-dense foods rather than sweetness itself, as these are the more relevant targets for addressing overweight and obesity. The study highlights the distinction between sweetness and sugar, noting that a food can taste sweet due to the presence of sugar, low-calorie sweeteners, or naturally occurring sugars.

It also points out that some foods may not taste particularly sweet but can still contain significant amounts of sugar. Therefore, public health organizations may need to reevaluate their recommendations and concentrate on reducing sugar and energy-dense food consumption to improve health outcomes.
