There is no compelling evidence to support the health benefits of sugar-free sweeteners, and potential damages can not be ruled out, according to a review of the study published in the British Medical Journal.
Growing concern about health and quality of life has encouraged many people to adopt healthier lifestyles and avoid foods rich in sugars, salts or fats. Therefore, Foods and drinks that contain sugar-free sweeteners instead of ordinary sugars have become increasingly popular.
Although several unsweetened sweeteners have been approved for use, less is known about their potential benefits and damages within acceptable daily intakes, because the evidence is "often limited and conflicting," say the study authors.
To better understand this, a team of European researchers from countries such as Hungary, Germany or France, analyzed 56 studies commissioned by the World Health Organization (WHO), which compared the consumption of ingested or lower intake of sugar-free sweeteners with higher intakes in healthy adults and children. They measured weight, blood glucose control, oral health, cancer, cardiovascular disease, kidney disease, mood and behavior. The studies were evaluated for bias and certainty of the evidence.
In general, for most of the results there appears to be no statistically or clinically significant difference between people exposed to sugar-free sweeteners and those who are not; or between different doses of sugar-free sweeteners.
For example, the results in adults of some small studies suggested small improvements in body mass index and fasting blood glucose levels with sugar-free sweeteners, but the certainty of this evidence was low. The lowest intake of unsweetened sweeteners was associated with a slightly lower (-0.09 kg) gain in weight than the higher intakes, but again the certainty of this evidence was low.
In children, a lower increase in body mass index score was observed with non-sugar sweeteners compared to sugar, but the intake of sugar-free sweeteners did not differ with body weight. In addition, they have not found sufficient evidence of any effect of sugar-free sweeteners on overweight or obese adults or on children trying to lose weight actively.
The International Sweeteners Association, which brings together much of this industry, has reacted to the study, highlighting the part that confirms the connection between sweeteners and weight loss or dental hygiene, according to a statement. He also questions that the WHO-mandated review excludes some studies on soft drinks and youths indicating weight loss and its long-term maintenance among young people who drank sugar-free soft drinks compared to those who drank them with sugar, The Country ". & # 39;
