Your patients may be worried about their weight as they get ready for Thanksgiving dinner and the other big meals that accompany the holiday season.
But do they understand the connections between diet and eye health?
The American Optometric Association offers some tips for eye-healthy eating on Thanksgiving and beyond. They’re worth keeping in mind and sharing with your patients.
It’s not only the holiday greens, but also the yellows, reds and oranges of a nutrient-rich diet that contribute to an eye-healthy smorgasbord at the holiday dinner table, the AOA notes. Carotenoids are powerful antioxidants that protect against cellular damage, and when combined with other essential vitamins and nutrients, provide health benefits vital for aging eyes.
Vitamins C and E, zinc, lutein, zeaxanthin and omega-3 fatty acids all play important roles in reducing the risks for certain eye diseases. The National Eye Institute’s Age-Related Eye Disease Studies (AREDS and AREDS2) found that increased antioxidant vitamin intake reduced advanced age-related macular degeneration risk by about 25 percent and reduced vision loss by 19 percent. Other recent studies showed that higher vitamin C and E intake lowered overall cataract risk and progression.
Thanksgiving and other holiday meals aren’t typically renowned for their healthy fare, but a few conscious menu choices could offer the family healthy options not only beneficial for eye health, but also for overall health.
Dr. Daniel Bintz, AOA health promotions committee member, says though Thanksgiving is sometimes interpreted as “free pass to eat it all,” anything in moderation is a good rule most dieticians use.
“For ocular nutrition, the rules don’t really change — more fruit and veggies, and the more raw, or non-prepared, the better,” Bintz says.
Bintz and Georgia Air National Guard Maj. Jennifer Carver, O.D., who also has a culinary degree, offer their suggestions for holiday eats.
1. Mindful menu options. “People don’t feel deprived on the holidays if you can make delicious, healthy substitutions,” Carver says. Try giving these traditional choices a healthy overhaul.
Instead of the carb-laden mashed, white potatoes, try mashed cauliflower instead. Steam a head of cauliflower and mince in the food processor until the proper consistency is reached, Dr. Carver says. Add sautéed leeks. Cauliflower is a very good source of vitamin C and omega-3s, both linked to proper visual development.
Try sweet potato oat bars, packed with healthy fats. Combine 5 baked and skinned sweet potatoes with 4 cups oats, 2 Tbsp. pumpkin pie spice, 2 Tbsp. coconut oil, ½ Tbsp. maple syrup, ¼ cup ground flax seed, ¾ cup coconut milk soured with 1 Tbsp. lemon juice, 1 tsp. salt, ½ dried fruit of choice and ½ cup chopped nuts of choice. Combine and bake in a 400-degree oven for 30 minutes. Sweet potatoes also are very good sources of vitamin C, as are fruits, and nuts are excellent sources of vitamin E. These vitamins can help slow progression of AMD and protect cells in the eyes from free radicals that break down healthy tissue.
2. Think color. Fill your plate with a rainbow of foods with carotenoids, Carver suggests. “Dark, leafy greens such as kale, spinach and collards have lutein, which is important for good macular function. Carrots and pumpkin are great sources of beta carotene and vitamin C,” she says.
3. Change it up. Bintz suggests instead of cooking “special items” for that one person in the family with a food allergy, diabetes or other dietary restriction, cook enough for the whole family to benefit. In his house, “we will have turkey and salmon,” Bintz says. Salmon is loaded with eye-rich nutrients, including zinc and omega-3 fatty acids. Zinc plays an essential role in bringing vitamin A from the liver to the retina in order to produce melanin, the protective pigment in the eyes.
