A recent study published at Harvard University’s annual meeting found that moderate coffee consumption may be beneficial for healthier aging. Researchers followed over 47,000 women for several decades and discovered a significant correlation between high caffeine intake from coffee and a lower risk of chronic diseases such as heart disease, diabetes, and neurodegenerative disorders.
The study defined healthy aging as reaching the age of 70 without major chronic diseases or cognitive impairment. Results showed that consuming caffeinated coffee led to a 13% greater odds of healthy aging compared to those who didn’t drink it. However, the researchers could not establish direct cause-and-effect due to the observational nature of the study.
In contrast, tea and decaffeinated coffee did not exhibit similar benefits. Interestingly, increased consumption of cola was linked to a significantly lower chance of healthy aging. To reap the benefits, experts recommend limiting daily coffee intake to two to four cups (8 ounces each) without excessive sugar and high-fat creamers.
Drinking coffee can provide alertness and memory support, but excessive caffeine can lead to negative side effects such as jitteriness, insomnia, headaches, or an increased heart rate.
