Instant coffee tied to almost sevenfold higher risk of vision problems, study finds
A recent study has suggested that consuming instant coffee may be associated with a significantly higher risk of vision problems, including glaucoma and other ocular conditions. According to the research, people who regularly drank instant coffee had an almost sevenfold increased risk of developing certain vision impairments compared to those who consumed other types of coffee or no coffee at all.
Key Findings of the Study:
- Higher Risk with Instant Coffee: The study found that compounds in instant coffee, such as higher levels of acrylamide (a byproduct of roasting) or other processing chemicals, might contribute to oxidative stress in the eye.
- Possible Mechanisms: The researchers hypothesized that certain additives or processing methods in instant coffee could lead to vascular or neurodegenerative effects on the optic nerve.
- No Strong Link with Brewed Coffee: Interestingly, filtered or brewed coffee did not show the same association, suggesting that preparation methods play a role.
Limitations & Need for Further Research:
- The study was observational, meaning it can’t prove causation.
- Factors like genetics, overall diet, and lifestyle may also influence the results.
- More research is needed to confirm these findings and explore the exact mechanisms.
What Should Coffee Lovers Do?
If you enjoy instant coffee, there’s no need to panic—but if you have a family history of glaucoma or vision problems, you might consider switching to brewed coffee or moderating intake until more conclusive evidence emerges.
