Researchers question the benefits of artificial sweeteners and sugar-free products
Sugar-free foods and drinks and products that are made using artificial sweeteners are often marketed as healthy alternatives, but new research has called the health benefits of such products into question.
A team of researchers based in Europe conducted a review of more than 55 studies that evaluated the impact of sugar substitutes. The team, led by researchers from the University of Freiburg, found that there were no significant differences between participants who had a high intake of artificial sweeteners and those who avoided sugar-free products. Some studies also suggested that a higher intake of substitute products contributed to greater weight gain than a lower intake. There was no concrete evidence to suggest that sugar-free foods and drinks can aid weight loss in those who are either overweight or obese.
A spokesperson for the British Dental Association, suggested that promoting sweetened products was counterproductive for good health, especially in the case of oral health. Diet fizzy drinks, for example, may not be laden with sugar, but they are more acidic than vinegar, and this contributes to enamel erosion and an increased risk of decay and gum disease. The only alternative to fizzy drinks and sugary smoothies and juices that are endorsed by the BDA are milk and water.
The study has been published online in the British Medical Journal.
