Diet (2011), Cataract Risk & Vegetarianism
Learn more about cataracts.
In this study the researchers looked into the relationship between diet and risk of cataract. The study subjects were 27,670 non-diabetic people aged 40 and more, a large proportion of whom were vegetarians.
The researchers used a testing model known as the Cox proportional hazards regression to evaluate the risk.
They found a strong correlation between the risk of cataract and the type of diet. The subjects who ate the most meat had the highest rate of cataracts, and those who ate fish, but not meat had a lower rate, vegetarians had a lower rate and vegans had the lowest rate of cataract incidence.
