Not So Secret Nutritional Secrets For Healthy Brain and Visual System
Eat your foods as your medicines, or you will have to eat your medicines as your foods.
~ Unknown, possibly Hippocrates
The quote above is believed to possibly have been attributed to Hippocrates the father of medicine, but many medical experts use this same statement as their own. In my house it was my mother. If you are like me, then you grew up with the idea that you should eat carrots and other great sources of Vitamin A / Betacarotene, for better eye sight. I have good news and bad news. The good news is that there is a lot that is known about the variety of nutrients in various foods that will help vision, the bad news is that you most likely will need to eat your vegetables and you will want more than just carrots. If you are a vegan, you might find it difficult to get the best nutrients in high enough concentrations, so I hope this information helps guide your thinking.
According to Dr. James McDonnell, a pediatric ophtalmologist at Loyala University Health System in Maywood, Ill., “Make a colorful plate, espThe ecially greens, blues and reds. Certain foods have distinct benefits to the eyes in addition to overall health, including many of the trendy superfoods such a kale, broccoli and sweet potatoes.” As you will see in the lists below, that different kinds of seafood are among the richest sources of nutritional benefit to developing and aging eyes.

What are the best sources of omega-3?
Fish sources Vegan sources Supplements
There are three main types of omega-3 fatty acid, which are called ALA, DHA, and EPA.
Plant sources, such as nuts and seeds, are rich in ALA, while fish, seaweed, and algae can provide DHA and EPA fatty acids. Eating a variety of omega-3 sources is important.
For each fish below, the serving size is 3 ounces (oz):
1. Mackerel - 0.59 g of DHA, 0.43 g of EPA
2. Salmon - 1.24 g of DHA, 0.59 g of EPA
3. Seabass - 0.47 g of DHA, 0.18 g of EPA
4. Oysters - 0.14 g of ALA, 0.23 g of DHA, 0.30 g of EPA
5. Sardines - 0.74 g of DHA. 0.45 g of EPA
6. Shrimp - 0.12 g of DHA, 0.12 g of EPA
7. Trout - 0.44 g of DHA, 0.40 g of EPA
8. Seaweed and algae - amounts vary widely
Seaweed, nori, spirulina, and chlorella are one of the few plant groups that contain DHA and EPA.
9. Chia seeds - 5.055 g of ALA per 1-oz serving. 10. Hemp seeds - 2.605 g of ALA in 3 tablespoons 11. Flaxseeds - 6.703 g of ALA per tablespoon. 12. Walnuts - 3.346 g of ALA per cup.
13. Edamame - 0.28 g of ALA per half cup
14. Kidney beans - 0.10 g of ALA per half-cup. 15. Soybean oil - 0.923 g of ALA per tablespoon
"Blueberries, bilberries and especially black currants contain high amounts of anthocyanins and help to maintain the health of the cornea and blood vessels in every part of the eye," McDonnell said. "They also help reduce the risk of cataracts and macular degeneration as well as decrease inflammatory eye disease and diabetic retinopathy."

Vitamin D helps prevent age-related macular degeneration and improve vision.

"Safe sun exposure, fish oils, fatty fish and, to a lesser extent, beef liver, cheese, egg yolks and certain mushrooms contain this master hormone, which acts on more than 4,000 genes," McDonnell said. He added that vitamin D3 supplementation has been shown to help prevent age-related macular degeneration, reduce retinal inflammation and improve vision.
Foods fortified with vitamin D
Secondary Sources Beef liver
Greens such as...
Spinach Romaine lettuce
...pack a nutrient called zeaxanthin.This nutrient, which McDonnell said reduces the risk of age-related macular degeneration, is found in dark green vegetables such as kale, broccoli, collards, raw spinach and romaine lettuce. "Lightly cooking these vegetables increases your body's ability to absorb these nutrients," McDonnell said.
"The best source is from organic eggs laid by pastured organic hens. You can also take supplements made from marigold flowers," McDonnell said.
Lutein and Zeaxanthin Combined
Dark Leafy Greens
Marigold Flower Supplement
Red and Yellow Onions
You can find bioflavonoids in the pulp and white core that runs through the center of citrus fruits, green peppers, lemons, limes, oranges, cherries, and grapes. Quercetin is a highly concentrated form of bioflavonoids found in broccoli, citrus fruits, and red and yellow onions. Foods high in bioflavonoids may help you stay healthy. Hosts of experiments on bioflavonoids have suggested that these key nutrients help increase immune system activation. These biochemically active substances accompany vitamin C in plants and act as an antioxidant.
Beta-carotene, contained in carrots, sweet potatoes, spinach, kale and butternut squash, protects you against night blindness and dry eyes, the eye doctor noted. It’s easy to get enough Beta-carotene through the following foods, so supplementation is not necessary and can be harmful if taken too often.
The foods highest in beta carotene include:
dark leafy greens - kale and spinach sweet potatoes
butternut squash cantaloupe
red and yellow peppers apricots
romaine lettuce paprika
My recommendation is to add 1 item from every nutrient group. Keep in mind that the items high on the list are better sources, so go as high on the list as you can. Be sure to mix things up, trying some new foods, herbs and spices to keep it interesting.
