RIO – Low calorie artificial sweeteners may not help to lose weight or improve health. This discovery is part of a study conducted by Harvard University in the United States, at the request of the World Health Organization (WHO), published in the British Medical Journal (BMJ) at beginning of January.
The study badyzed 56 studies on the impact of the use of sweeteners, such as aspartame and stevia, on weight, blood sugar control and diseases cardiovascular. The study concluded that there was "no relevant statistical or clinical difference between those who use sweeteners and sugar".
The impact of the product was observed according to parameters such as oral health, kidney and cardiovascular diseases, cancer, blood sugar levels, weight and BMI in adults and children.
For researchers, evidence that the use of sweeteners would help reduce BMI and blood sugar levels was considered unconvincing, including in people considered obese or overweight. In children, the small reduction in weight gain related to use would not affect body mbad.
The study was also looking for evidence of side effects related to the use of substances, but the badyzes were considered inconclusive. Officials emphasized the need for further research to further the findings of the report.
– Long-term studies are needed to evaluate the effects on overweight and obesity, the risk of diabetes, cardiovascular disease and kidney disease – the researchers said.
The editorial of the journal, written by researcher Vasanti S. Malik of the Harvard School of Public Health, confirmed the need for further study:
The main trials to date show that replacement of sugary drinks with alternatives reduces weight gain in children and adolescents after one year of follow-up. We can not neglect that.
However, for Malik, replacing sugars with sweeteners, especially in beverages, "may be a useful strategy for reducing cardiometabolic risk [chances de ter diabetes e doenças cardíacas] among consumers, as well as for other healthy beverages".
– Policies and recommendations will need to be updated regularly as more evidence is provided to ensure the best available data are used to inform the important debate about sugar in public health and its alternatives .
Beverage manufacturers worldwide are under pressure to reduce the sugar content of their products, due to obesity. In England, for example, the head of public health has advocated a 20% reduction in the sugar index by 2020, with a 5% reduction by April 2018. The sector was unable to reach this target, reaching 2%. more.
Many companies have chosen to use artificial sweeteners instead of sugar, especially in non-alcoholic beverages. The aim of the WHO is to produce sweetener guidelines as their use continues to be considered a "healthy alternative to sugars".
