High vitamin K1 intake linked to reduced cataract risk

May 20, 2017

(HealthDay)—High intake of vitamin K1 is associated with reduced risk of cataracts, according to a study published online May 11 in JAMA Ophthalmology.

María L. Camacho-Barcia, R.D., from the University Hospital of Sant Joan de Reus in Spain, and colleagues examined the correlation between dietary K1 intake and the risk of incident cataracts in 5,860 participants (mean age, 66.3 years) from a carried out between 2003 and 2011 (Prevención con Dieta Mediterránea Study). A validated food frequency questionnaire was used to assess dietary vitamin K1 intake.

The researchers found that there were 768 new cataracts documented after a median of 5.6 years of follow-up. After adjustment for potential confounders, the risk of cataracts was lower among participants in the highest versus the lowest tertile of dietary vitamin K1 intake (hazard ratio, 0.71).

"High intake of dietary vitamin K1 was associated with a of cataracts in an elderly Mediterranean population even after adjusting by other potential confounders," the authors write.

Several authors disclosed financial ties to the nutrition industry; the supplemental foods used in the study were donated by Comunal Olivarero and Hojiblanca, the California Walnut Commission, and La Morella Nuts.
