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.”
