A large-scale prospective cohort study has found evidence supporting a more detailed clinical dietary recommendation for cataract prevention.
The study initially included 72,160 participants from the UK Biobank who were free of cataract between 2009-2012, during which period their frequency and type of fruit and vegetable intake was assessed.
After a mean follow-up period of 9.1 years, 5,753 participants had developed cataract and Cox proportional regression models were used to estimate the association between fruit and vegetable intake and the incidence of cataract.
It concluded that a high level of evidence showed increased intake of fruit and vegetables were beneficial regarding cataract risk, with legumes, tomatoes, apples and pears noted as particularly helpful.
