Beware coffee lovers! New study reveals this type of common brew can make you blind. And it's incurable

Love coffee? If your day doesn’t start without a steaming cup of coffee, you might want to take a closer look at what’s in your mug. A new study has revealed the danger of consuming a commonly consumed type of coffee, linking it to an increased risk of blindness among those who drink coffee regularly.

The study, published in the journal Food Science & Nutrition, mentions that instant coffees can increase your risk of getting age-related macular degeneration (AMD) by 700 per cent.

AMD is the leading cause of blindness. And it is incurable!

The study mentions that the results showed a genetic correlation between those who consume instant coffees and dry AMD. In fact, with every increase in instant coffee intake, the risk of getting dry AMD was nearly seven times higher.

“Our results revealed a genetic correlation between instant coffee consumption and dry AMD, with each standard deviation (SD) increase in instant coffee intake associated with a corresponding odds ratio (OR) of approximately 6.92 for dry AMD, indicating a 6.92-fold increased risk,” the study says.

“Instant coffee may increase the risk of AMD, and reducing its intake could help prevent dry AMD.” It further suggests that people who are at high-risk for AMD should avoid instant coffee.

There are two types of AMD: wet AMD and dry AMD.

Dry AMD: The most common type of AMD has no exact cause. According to John Hopkins, the “loss of vision in this condition is usually slow and gradual.”

Wet AMD: Though this type is less common, it usually leads to more severe vision loss in patients than dry AMD, John Hopkins says.

It is the most common cause of severe loss of vision.

“Wet AMD happens when abnormal blood vessels start to grow beneath the retina. They leak fluid and blood – hence the name wet AMD – and can create a large blind spot in the center of the visual field,” it said.
