Sugar-Free Sweets May Trigger Digestive Issues, New Report Warns

Sugar-free sweets may pose unexpected risks to health, according to a new report. The Consumer Center Hamburg has found that many of these products contain high levels of sugar substitutes with laxative effects. Even small amounts can cause discomfort for some consumers. The investigation tested 16 sugar-free sweets, all of which exceeded the 10% threshold for sugar substitutes. This level legally requires a warning label about possible laxative effects. The highest concentration—97%—was found in Tictac Two Fresh & Mild Spearmint Flavor Mint Candies.

Sugar substitutes like sorbitol and maltitol can trigger diarrhoea in sensitive individuals with as little as 10 grams per serving. These alternatives, often used to replace refined sugar, have been common in processed foods for decades. However, they come with their own risks, including potential addiction and digestive issues.

The report also highlights the high cost of sugar-free products. Bars can reach around 50 euros per kilogram, while gummy bears often cost twice as much as their sugar-containing counterparts. Back in 2012, the Federal Council banned the label ‘Suitable for Diabetics’ for diet products after scientific evidence proved insufficient. Experts suggest that reducing sugar intake through gradual, targeted cuts is more effective than relying on substitutes. The findings serve as a reminder that sugar-free options may not always be the healthier choice. Consumers are advised to check labels and be aware of potential side effects before purchasing.
