Our vision is crucial to our survival. The good news is Nature has provided us with the means to support healthy vision. These superfoods have been proven to promote excellent eye health.
Blueberries are an excellent source of antioxidants and anthocyanin that have been proven in numerous studies to help prevent macular degeneration and slow the growth of cataracts in the elderly.
It has been observed in subjects who included blueberries in their diet, a heightened level of protection around the retina and an improvement in night vision.
Dark leafy green vegetables such as kale, spinach and chard are very high in the carotenoids that are important for the support of vision health. The two most significant of these, lutein and zeaxanathin, help to protect the retina from the harmful rays of UV light and prevent macular degeneration and cataracts.
Wild Alaskan Salmon an important source of Omega 3 fatty acids that protect the eye from macular degeneration. It has also been demonstrated in studies that dry eye syndrome was significantly reduced in those who included salmon regularly in their diet. Wild Alaskan salmon also contains a powerful antioxidant, Astaxanthin, which fights oxidative damage that can lead to macular degeneration. Astaxanthin also offers powerful protection from UVB rays.
Orange and yellow vegetables such as pumpkin, carrots, squash, peppers are high in vitamin A and function to protect the cornea of the eye. They are also an important source of a class of antioxidants called beta-carotenes that also help slow macular degeneration and improve vision health.
Egg yolks are rich in the antioxidants lutein and zeaxanathin which helps protect the eyes from UV radiation. Scientist now believe that the body is more easily able to absorb lutein and zeaxanathin from eggs than from dark leafy greens.
A healthy diet is your first line of defense regarding vision health. Integrating these superfoods into your diet is a powerful step to optimal vision health!
