Artificial sweeteners can have various negative health effects
Many people do without sugar if they want to eat healthier or lose some weight. Affected people then often start using artificial sweeteners instead of sugar. But researchers have now found that artificial sweeteners are associated with weight gain, an increased risk of diabetes, heart disease and high blood pressure.
Scientists at the University of Manitoba in Canada found that taking artificial sweeteners can have various negative effects. These included, for example, weight gain, heart disease and high blood pressure. The doctors published the results of their study in the Canadian Medical Association Journal.
Slimming effects of sweeteners are exaggerated
The results of the current large-scale study now showed that artificial sweeteners can also lead to problems with metabolism, intestinal bacteria and appetite. In addition, the perceived slimming effects on weight are exaggerated, the experts from Canada explain.
Researchers analyzed the data from more than 400,000 subjects
The scientists at the University of Manitoba examined a total of 37 studies that medically monitored more than 400,000 people for an average period of ten years. The experts found that the intended benefits of weight loss are not supported by scientific evidence.
The advantages and disadvantages of sweeteners have so far been contradictory
Despite the fact that millions of people routinely consume artificial sweeteners, relatively few of these patients have been closely examined in clinical trials, says author Professor Ryan Zarychanski. The evidence about the advantages and disadvantages of sweeteners was very contradictory, adds the expert.
More research is needed
Caution is warranted until the long-term health effects of artificial sweeteners are fully characterized, author Meghan Azad explains. Given the widespread and increasing use of artificial sweeteners and the current epidemic of obesity and related diseases, more research is needed to accurately determine the long-term risks and benefits of these products, the scientist says.
Health authorities had previously rated sweeteners as safe
Of course, there are other opinions on the subject. Low and high-calorie sweeteners have been rated as safe by all the world's leading health authorities, including the European Food Safety Authority.
Results of previous research on this topic incorrect?
The results of the University of Manitoba research show contradicting results in relation to the extensive scientific research that has previously claimed that low-calorie sweeteners can help people reduce their calorie intake and thus manage their weight better, the authors explain. (as)
