Omega-3 Fatty Acids in the blood linked to less risk of Macular Degeneration (AMD)
What is Macular Degeneration? Macular degeneration causes loss in the centre of the field of vision. In dry macular degeneration, the centre of the retina deteriorates. With wet macular degeneration, leaky blood vessels grow under the retina. Blurred vision is a key symptom.
Eating more salmon and other oily fish and seafood high in omega-3 fatty acids (sardines, mackerel, tuna, anchovies, oysters) may reduce your risk of macular degeneration.
Researchers in France evaluated levels of EPA and DHA in the blood serum and red blood cell membranes of 290 patients with wet AMD in one eye and early AMD lesions in the other eye and 144 patients without AMD in either eye. Dietary intake of seafood was estimated by a food questionnaire completed by all participants.
Dietary oily fish and seafood intake were significantly lower in AMD patients compared with healthy patients without AMD. After adjusting for age, gender, family history of AMD and other factors, higher serum EPA levels were significantly associated with a lower risk for neovascular AMD.
Higher levels of EPA and combined EPA and DHA levels in red blood cell membranes also were significantly associated with a lower risk for wet AMD.
The study authors concluded that blood levels of EPA and DHA omega-3 fatty acids, particularly levels found in red blood cell membranes, may be a useful objective marker to identify people at risk for neovascular AMD and those who might benefit most from changing their diet to reduce risk of macular degeneration.
Vitamin B1 Deficiency Linked To Brain Damage And Vision Loss
In extreme cases, normally due to alcoholism, anorexia or other disorders that lead to malnourishment, vitamin B1 (thiamine) deficiency can cause Wernicke encephalopathy.
Sunflower seeds, pork and macadamia nuts are among the foods that are high in vitamin B1.
This serious neurologic disorder is associated with eye problems like double vision and involuntary eye movement, and can even lead to irreversible brain damage and death, according to researchers at Loyola University Medical Center.
Wernicke encephalopathy is often undiagnosed. “Particularly in those who suffer from alcoholism or AIDS, the diagnosis is missed on clinical examination in 75 to 80 percent of cases,” wrote the researchers.
Thiamine is an essential vitamin for a variety of organ functions, including the nervous system. The current recommended daily value for vitamin B1 is 1.4 mg. Foods rich in thiamine include lean pork, sunflower seeds, trout, edamame and macadamia nuts.
Please look after your eyes by eating a healthy diet
Very important: Always make sure you discuss and make decisions about your eye care based upon a formal appointment with your optician.
