Celiac disease (also called gluten-induced enteropathy) is an intestinal disorder that results from intolerance to gluten, a protein found in wheat, oats, barley, and rye.  Eating gluten containing foods damages the small intestine and makes it impossible for sufferers to absorb nutrients properly, including vitamin A, which the eyes need to function in low light conditions.

Celiac disease may not cause symptoms in some people. However, people with the condition may report history of frequent, loose, watery stools; pale, foul-smelling, bulky stools; abdominal pain, gas and bloating; weight loss; fatigue; canker sores; muscle cramps; delayed growth or short stature; bone and joint pain; seizures; painful skin rash; and infertility. In addition to physical symptoms, there may be emotional disturbances including feelings of anxiety and depression.

Celiac disease can also cause nightblindness. Trouble in the intestinal tract can mean the body does not absorb enough essential vitamin A (a key component of beta-carotene and the reason your mom told you that carrots would help you eye sight).  Therapeutic doses of vitamin A can help correct the problem.   The best form of vitamin A is known as palmitate, taken in a daily dose of 15,000 international units.

Retinitis Pigmentosa (pigmentosis) is a progressive degenerative disorder of the retina that can cause a profound loss of vision. Various hereditary patterns have been reported. This disease affects 1 out of 3700 people.

A study published in the Archives of Ophthalmology showed that taking 15,000 IU of Vitamin A per day can slow the progression of retinitis pigmentosa.  On the other hand, this same study showed that taking Vitamin E supplements actually accelerated vision decline.

The conventional medical opinion posits that there is no treatment or cure for retinitis pigmentosa, but we believe that a progressive approach to maintaining a healthful diet and lifestyle can slow down RP, and, in some cases, even help to preserve vision.  In addition to Vitamin A, supplementing the diet with lutein, omega-3 fatty acids, other antioxidants and COQ10 have all been shown to benefit RP sufferers.

Scientists at the Laboratory for Nutrition and Vision Research have found that the regular consumption of specific “protective nutrients” in conjunction with  a low-glycemic-index, or “slow carb,” diet protected study participants from age-related macular degeneration. A food’s glycemic index is an indicator of how fast the carbohydrate it contains will spike blood sugar levels.

Vitamins C and E, zinc, lutein, zeaxanthin, and the omega-3 fatty acids DHA and EPA taken as part of a diet rich in low-glycemic-index foods reduced the risk of developing AMD.

At the American Glaucoma Society meeting, Dr. JoAnn A. Giaconi reported that women who reported eating greater amounts of fruits and vegetables appeared to have a lower likelihood of developing glaucoma.

The foods that seemed especially protective included fresh oranges, peaches, spinach, collard greens, and kale.

Dr. Giaconi presented results from a review of data from the Study of Osteoporotic Fractures.  In this study involving a subset of 584 black women, glaucoma was diagnosed in at least one eye in 77 participants.  Disc photos and suprathreshold visual fields were evaluated in conjunction with Block Food Frequency Questionnaires on the participants’daily food consumption.

The results?

• Eating three or more servings of fruit or fruit juices daily decreased the odds of black women developing glaucoma by 79%
• Eating one serving of collard greens or kale decreased the odds of glaucoma by 57%
• Eating more than two servings per week of fresh oranges and peaches also significantly decreased the chance of developing glaucoma.

Researchers believe that the antioxidants in fruits and vegetables (vitamin A, alpha- and beta-carotene, folate, lutein, zeaxanthin) can potentially block oxidation stress that can lead to cell damage in glaucoma.
