For years, scientists thought that moderate drinking might be good for your health, but new evidence suggests that even small amounts of alcohol can have negative cognitive effects. Experts say that people should be aware of the risks and manage their own intake.
The study’s lead author, Joel Gelernter, used to drink one glass of wine a day due to the data suggesting it was safe for cognition. However, he now thinks that even a small amount of alcohol may harm brain health over time.
Experts agree that while it’s okay to drink, relying on self-reported data can be problematic. They found that increasing alcohol intake invariably increases dementia risk. In fact, every threefold increase in drinking prevalence is associated with a 15% increased risk of dementia.
The study also showed that moderate drinking was linked to smaller gray matter and increased iron in the brain, which has been linked to neurodegenerative diseases like Alzheimer’s and Parkinson’s.
So, how can you manage your alcohol intake? Experts suggest trying challenges like Sober October or Dry January, working with a doctor for heavier drinkers, and avoiding binge drinking. You can also spread out your intake, reduce ethanol percentage, and alternate drinks with soft drinks.
Ultimately, it’s essential to be aware of the risks and make informed decisions about your drinking habits.
