Eye Care Nutritionals
Eye Care Nutritionals Can Benefit Ocular Health
The Denver Eye Care professionals at Vision Care Specialists expect a significant increase in age-related eye disease over the next 20-30 years due to an aging baby boomer generation. This demographic change, along with the changes that have occurred in our diet over the last 40 years, will lead to more Americans developing diseases such as diabetes, hypertension, autoimmune diseases & obesity. These systemic diseases increase the risk for ocular diseases such as age-related macular degeneration (AMD), cataracts, dry eye, and hypertensive and diabetic retinopathy. Therefore, disease prevention should become more of a focus during your routine eye care exams.
We know that age and genetics are risk factors for certain diseases. Unfortunately, we are unable to change those two variables. We are, however, able to modify our lifestyle to decrease our risk for certain diseases. Our lifestyle, which includes diet and exercise, should be geared towards decreasing our body’s inflammation and improving our cardiovascular health.
- Increase your intake of omega-3 essential fatty acids (EFA) to lower your body’s inflammation. EFAs are required by the human body in order to function properly and must come from our diet. The proper balance recommendation by the Institute of Medicine is 4:1 – four times as many Omega-6 EFAs as Omega-3 EFAs. The typical American diet is too high in omega-6 EFAs and often our ratio is 20:1.
- Omega-3 EFAs can be found in salmon, sardines, cod liver oil, tuna, flaxseed, and walnuts. These EFAs are anti-inflammatory.
- Healthy omega-6 EFAs can be found in borage and primrose oil.
- Unhealthy omega-6 EFAs are abundant in modern diets. Refined vegetable oils, such as soy oil, are used in processed & fast foods. Soybean oil alone is now so common that it supplies up to 20% of the calories in the typical Western diet.
- Decrease your intake of foods high in saturated & trans fats. Trans fats are found in margarine, packaged foods, soups, fast foods, frozen pies & pizza, donuts, cakes, cookies, and candy. These “bad fats” increase inflammation in your body thus increasing your risk for chronic vascular disease.
- Increase your intake of complex carbohydrates such as vegetables, nuts, grains, and beans are necessary for fiber and stable glucose/insulin levels.
- Decrease your intake of foods that contain high fructose corn syrup.
- Increase your intake of colorful fruits and dark green leafy vegetables such as spinach, collard greens, broccoli & kale. These dark green leaves contain yellow pigments (lutein & Xeaxanthin) that offer protection of various tissues in the eye including the macula, retina, and lens. Other sources of these two pigments can be found in corn, eggs, and supplements. Fruits and non-starchy vegetables cause a more limited rise in blood sugar while providing fiber for intestinal health. Fruits and vegetables are also an excellent source of antioxidants and minerals.
- Decrease your intake of refined grains, starches, and sugars. http://downsizingyourbody.com/
- Increase your intake of water and decrease your intake of soda and other sugary drinks. Stay hydrated!
- Supplement your diet with a full spectrum nutritional supplement that offers a guaranteed daily consumption of antioxidants, B vitamins, Vitamin D, eye-specific carotenoids (lutein, zeaxanthin, and lycopene), and minerals. If you are pregnant or nursing or are taking blood thinners (anticoagulants), speak to your doctor before using any type of nutritional supplement. A nutritional supplement is not intended to replace a balanced diet, but to compliment it. A few specifics:
- Vitamin C: promotes healthy capillaries, supports ocular blood vessel health, decreases the risk of AMD and cataracts. The half-life of Vitamin C in the bloodstream is about 30 min. In other words, if you take 1000mg then only 500 mg remains in the bloodstream after 30 min. Within 6 hours, there is virtually nothing left. It is better to get 500 mg twice daily than 1000 mg once daily.
- Lutein (10mg) with Zeazanthin (2 mg): these are carotenoids that protect and maintain healthy cells in the eye especially in the macula.
- Vitamin E: 200-400 IU – found in wheat germ and most seeds and nuts.
- DHA /EPA Omega-3 EFA: 2000-3000 mg of fish oils -preferably triglyceride form. Supports cardiovascular, immune and nervous system. Decreases inflammation. Improves dry eye syndrome when combined with certain omega-6 EFAs.
- Vitamin D: Check your level with your PCP. If your test results are under 30, then you are deficient. Your levels tend to be higher in the late summer months and lower in the winter months because our main source comes from exposing our skin to sunlight. Researchers have found over 2500 genes are activated by Vitamin D and significantly influence 229 of them. Some of these genes are associated with MS, rheumatoid arthritis, Crohn’s disease and Type 1 diabetes as well as some cancers. http://www.vitamindcouncil.org/
- Zinc: an essential trace mineral found in red meat, poultry, oysters and breakfast cereals. Evidence suggests that taken with other essential nutrients this mineral can slow the progression of AMD.
- If you plan to begin a regimen of eye care supplements, be sure to discuss this with one of our Colorado eye doctors. Taking too much of certain vision supplements can cause problems, especially if you are taking prescription medications for health problems.
