Eyesight is a terrible thing to waste. Choose your oils wisely. Then look at beautiful things.
Regularly eating fish, nuts, olive oil and other foods containing omega-three fatty acids and avoiding trans fats appears to be associated with a lower risk for the eye disease age-related macular degeneration, according to two reports in the May issue of Archives of Ophthalmology, one of the JAMA/Archives journals.
By 2020, as many as 3 million Americans are expected to have late-stage age-related macular degeneration (AMD), according to background information in one of the articles. AMD is the leading cause of severe vision loss among individuals older than 65 in the developed world. Established risk factors include age, genetic markers and smoking (the only consistently reported modifiable risk factor).
In one report, Jennifer S.L. Tan, M.B.B.S., B.E., of Westmead Hospital, University of Sydney, Australia, and colleagues studied 2,454 participants in the Blue Mountains Eye Study, which began in 1992 to 1994. At that time, participants completed a food frequency questionnaire that was analyzed to determine their intake of various fatty acids. Digital photographs of the retina were used to assess the development of AMD five and 10 years later.
After adjusting for age, sex and smoking, eating one serving of fish per week was associated with a 31 percent lower risk of developing early AMD. The association was stronger among individuals with a lower intake of linoleic acid, an unsaturated omega-6 fatty acid found primarily in vegetable oils. Eating one to two servings of nuts per week was associated with a 35 percent lower risk of early AMD.
My question: Can one scale up one's omega 3 consumption to counterbalance the effects of consuming larger amounts of omega 6 fatty acids?
I periodically tweak my diet to improve it in various ways. One of my recent additions is to use olives as condiments on my lunch. I am guessing that the whole olives are more beneficial than just the olive oil since the olives will contain more of the non-oil compounds that are suspected of delivering additional health benefits. Get the beneficial oils but with more other good stuff.
