You thought it was “less worse” to consume energy drinks without sugar than their sweet counterparts? Maybe not in the end. Two studies report that excessive consumption of energy drinks, even without sugar, can cause significant damage to brain cells and increase the risk of heart disease, stroke and type 2 diabetes.
The first study, published in Frontiers in Nutrition, found that excessive consumption caused damage to blood vessels in the brain. The other study, published in Nutrients, found that energy drinks induce a metabolic syndrome. If, for the moment, these results have been obtained on mice, they could be transposed to humans.
“Energy drinks containing large amounts of caffeine and sugar are consumed more and more, especially by young people. Many may believe that the sugar-free varieties are ‘healthier’ for them, but our studies have shown the opposite, “said lead researcher for both projects, Associate Professor Ryusuke Takechi of the Curtin Health Innovation Research Institute. : “Our first study looked at potential brain damage and found that energy drinks, even sugar-free forms, disrupt blood vessels and increase blood pressure.inflammation in the brain mouse models “.
And sugar-free energy drinks did not provide more reassuring conclusions: “What was particularly interesting here was that we found that energy drinks without sugar also promoted metabolic syndrome and increased blood sugar and cholesterol in model mice, at levels similar to standard energy drinks. “Regardless of whether the drink contained (or not) sugar, it would appear to lead in the long run.”increased blood sugar and bad fats (triglycerides) “. Studies must now confirm these conclusions in humans in order to understand the effects of the various specific components of these drinks, including artificial sweeteners.
