Omega 3 fatty acids have been shown to increase the general sense of well-being and promote high health. They are present in fish and are highest in mackerel, white fish, tuna, and salmon.
Zinc has a specific role in the normal functioning of photoreceptors in the eye. Zinc is found in high protein foods such as beef, pork, and whole grain cereals.
Recently, it has been suggested that the carotenoids, Lutein (pronounced loo-teen) and Zeaxanthin (pronounced zee-uh-zan-thin) play an important role in eye health.
In the Eye Disease Case Control Study, medical researchers found that individuals experienced a significantly lower risk for developing age related macular degeneration when they had high amounts of Lutein and Zeaxanthin in their blood.
Sources of Lutein include yellow peppers, mango, blueberries, and green leafy vegetables such as kale, spinach, chard, and broccoli. Sources of Zeaxanthin include orange sweet peppers, broccoli, corn, lettuce, spinach, tangerines, oranges, and eggs.
