Artificially sweetened drinks may increase the risk of stroke or dementia
Daily consumption of “diet” drinks containing synthetic sweeteners may be linked to an increased risk of stroke or suffering from dementia, according to a US study.
Risk of stroke in people over 45 and dementia in those over 60
American researchers have examined the effects of light beverages on health, particularly brain health. A recent study, published in the American Heart Association Stroke Journal, followed two groups of adults in the city of Framingham, Massachusetts: 2,888 adults over 45 years of age in the first group and 1,484 adults Of 60 years in the second group. The ages were not randomly selected, as the risk of stroke increases after 45 years and the risk of dementia increases after age 60.
The researchers noted artificially sweetened drinks in all participants and then studied stroke in the first group and the development of dementia in the second group. The observation took place from 1991 to 2001.
Almost 3 times more risk with daily consumption
According to the findings of this study, compared to people who never consume a “light” drink, those who consume it once a day would be almost 3 times more likely to have an ischemic stroke and almost 3 times more likely to develop dementia At an advanced age. For lower consumption (between 1 and 6 drinks per week), the risk is increased by an ischemic stroke (2.6 times more risk), but not to develop dementia.
The study’s lead author, Matthew Pace of Boston University School of Medicine, said the effects were due to effects on the cerebral vessels but remained cautious about the results. They do not prove any causal link between the consumption of artificially sweetened drinks and stroke or dementia. Surprisingly, this American study did not find an increased risk of stroke or dementia for regular drinks of sugary drinks (sodas with real sugar juices, etc.), where other studies Previous years had concluded the opposite.
“When the authors controlled for hypertension and diabetes and obesity the effects diminish, which implies that some of the effects of artificially sweetened beverages could still be going through a vascular pathway,” he said about the new study. “Many strokes are caused by hardening of arteries; and the risk of dementia is also increased by the hardening of arteries in large and small vessels. So, I believe the mechanisms may be through vascular disease, though we can’t prove it.”
The authors therefore emphasized that brain damage such as stroke or dementia is a result of several factors and that the best prevention is to follow healthy living rules (balanced diet and physical exercise).
