For most of us, an instant cup of coffee is the morning pick-me-up of choice. But a new research from Hubei University of Medicine in China indicates this easy drink may have a secret threat to your sight, especially for age-related macular degeneration (AMD).
Is your instant coffee habit damaging your eyesight? New research sparks fears
Published in Food Science & Nutrition, the study examined a large genetic dataset of more than 5,00,000 people and used sophisticated genetic correlation and Mendelian randomisation to investigate the association between coffee intake and AMD. The results showed a statistically significant genetic causal link exclusively between instant coffee consumption and the risk of dry AMD, the more prevalent form of the vision-stealing disease.
Incidentally, ground coffee and decaffeinated coffee had no such correlation, suggesting that the potential negative impact is specific to instant products. The study emphasized that an increase in the standard deviation of instant coffee intake was equivalent to a significantly higher risk of dry AMD.
AMD is one of the world’s leading causes of vision loss in older adults, with around 196 million people affected in 2020.
