Age-related macular degeneration risk may be reduced with the Mediterranean diet and caffeine: New study

Age-related macular degeneration risk may be reduced with the Mediterranean diet and caffeine: New studyAge-related macular degeneration risk may be reduced with the Mediterranean diet and caffeine. The latest findings found that age-related macular degeneration (AMD) risk was lower among those who ate a Mediterranean diet, especially eating lots of fruits. This is the first study to show the protective effects of caffeine against AMD.

Numerous studies have revealed the benefits of the Mediterranean diet in supporting a healthy heart and brain. The researchers then took it a step further to see how the Mediterranean diet may impact the development of AMD among a group of Portuguese people.


The researchers studied 883 individuals over the age of 55, of which 449 had early AMD and 434 did not have AMD. Diets were assessed using questionnaires asking how often they ate foods that are part of the Mediterranean diet. The researchers found the more frequently participants ate the Mediterranean diet foods the lower their risk of AMD was. Fruits were also seen highly beneficial in maintaining vision and preventing AMD, along with caffeine and antioxidant consumption.

Caffeine is not considered a part of the Mediterranean diet, but caffeinated beverages and food are often consumed in Mediterranean countries.

Lead author of the study Rufino Silva said, “This research adds to the evidence that a healthy, fruit-rich diet is important to health, including helping to protect against macular degeneration… We also think this work is a stepping stone towards effective preventive medicine in AMD.”
