A recent study conducted by researchers at the Westmead Institute for Medical Research in Australia has uncovered a potential link between regular orange consumption and a reduced risk of developing macular degeneration.

Macular degeneration is a progressive eye disease that can lead to vision loss, particularly in older adults.

This study, which followed over 2,000 Australian adults aged 50 and older for 15 years, found a significant association between consuming oranges and a lowered risk of late-stage macular degeneration.

Key Findings

Participants who reported eating at least one serving of oranges daily had over a 60% reduced risk of developing late-stage macular degeneration over the 15-year study period.

Even individuals who consumed oranges as infrequently as once a week showed significant benefits in terms of macular degeneration risk reduction.

Flavonoids, naturally occurring compounds found in oranges, are believed to play a role in protecting against macular degeneration.

The Role of Flavonoids

Lead researcher Associate Professor Bamini Gopinath from the University of Sydney highlighted the significance of flavonoids in oranges as potential protective agents against macular degeneration.

Flavonoids are potent antioxidants found in various fruits and vegetables and are known for their anti-inflammatory benefits for the immune system.

Distinguishing Factors of the Study

Unlike previous research that primarily focused on the effects of common nutrients like vitamins C, E, and A on eye health, this study delved into the relationship between flavonoids and macular degeneration.

While flavonoids can be found in many fruits and vegetables, the data from this study specifically pointed to oranges as having a protective effect.

Interestingly, the study did not find a significant relationship between other food sources rich in flavonoids, such as tea, apples, red wine, and the prevention of macular degeneration.

This highlights the potential unique benefits of oranges in reducing the risk of this eye disease.

Macular degeneration is a prevalent issue in Australia, affecting approximately one in seven individuals over the age of 50. Age is a significant risk factor for the disease, with its likelihood increasing after the age of 50.

Currently, there is no cure for macular degeneration, making prevention and risk reduction particularly important.


This study contributes valuable insights into the potential protective effects of regular orange consumption against late-stage macular degeneration.

The findings suggest that flavonoids found in oranges may offer specific benefits for eye health.

While further research is needed to confirm these findings and explore the underlying mechanisms, incorporating oranges into one’s diet may be a simple and accessible way to reduce the risk of this vision-threatening condition.
