Caffeine consumption linked to lower dementia risk in new study

A study published in the Journal of the American Medical Association (JAMA) suggests that moderate caffeine consumption may be linked to a lower risk of dementia and improved cognitive function. Based on data from over 130,000 participants in the Nurses’ Health Study and the Health Professionals Follow-Up study, researchers found that individuals consuming two to three cups of coffee daily (approximately 300 mg of caffeine) had an 18 percent lower risk of developing dementia compared to non-consumers. This moderate intake was also associated with slower brain aging and better performance on mental function tests.

Separately, gastroenterologist Dr. Andrew H. Moore of Endeavor Health advises caution regarding carbonated beverages in restaurants. Dr. Moore notes that both sugary sodas and sugar-free alternatives can negatively impact health. While sugary drinks contribute to metabolic issues and liver fat accumulation, carbonated drinks—even those with artificial sweeteners—can cause bloating and gas due to carbon dioxide. He emphasizes that ‘sugar-free’ labels do not necessarily mean a beverage is optimal for gut or liver health.
