Lutein
The word lutein comes from the Latin word luteus, meaning yellow. (1)
Lutein is a carotenoid found in spinach, green leafy vegetables including kale and broccoli, and egg yolks. It is an antioxidant that helps to fight free radicals and inflammation in the body. Unfortunately, our body cannot produce lutein so we must get it in our diet. Eating fats alongside lutein helps us to absorb it.
Lutein may help
- Stop macular degeneration
- Prevent cataracts
What are the benefits?
1) Macular degeneration
According to WebMD, lutein is one of two major carotenoids found as a colour pigment in the macula and retina of the human eye. Lutein is an antioxidant and thought to act as a light filter, which protects the eye tissues from sunlight damage. (2)
Lutein is more effective with another antioxidant called zeaxanthin found in papaya. Zeaxanthin may help to protect the eye from macular degeneration, which is associated with free radicals in the eyes.
2) Cataract prevention
The antioxidant properties of lutein could help prevent cataracts, which are caused by free radicals and oxidation. Free radicals can cause the lens to become cloudy, resulting in cataracts. Research shows that lutein and zeaxanthin may reduce the effects of these free radicals and protect the eye from the damage. Lutein and zeaxanthin are the only two antioxidants found in the eyes in high concentrations. (3)
May help with skin health
According to research, the antioxidants lutein and zeaxanthin could be beneficial for skin health. Antioxidants may protect the skin from damaging high energy wavelengths in sunlight. (3)
Lutein works well with
- Cod liver oil because of its vitamin A and vitamin D content which may help to maintain healthy eyesight
- Selenium to help to protect the eye from oxidative damage
