Dietary Intake of Omega-6 Fatty Acids May Protect Against Development of Cataracts
In a prospective study involving 12,308 men and women, initially
free of cataracts, results indicate that dietary intake of fatty
acids, particularly omega-6 fatty acids, may be inversely
associated with risk of developing cataracts. Fatty acids intake
was assessed using a validated 136-item semiquantitative food
frequency questionnaire. During a follow up of up to 6 years, 182
incident cases of cataracts were recorded. After adjusting for
confounders, the highest category of dietary intake of omega-6
fatty acids was associated with a 42% reduced risk of cataracts.
Similarly, the highest category of dietary intake of fatty acids
(saturated, monounsaturated, polyunsaturated omega-6 and
polyunsaturated omega-3) was associated with a 46% reduced risk of
development of cataracts. Thus, the authors of this study conclude,
'High intake of omega-6 fatty acids showed a modest but significant
inverse association with the development of cataracts.
