Food Sources of Lutein and Zeaxanthin for Healthy Eyes

Age-related Macular Degeneration (AMD) and cataracts are the most prominent causes of visual impairment affecting millions of people. Prevention or delaying the progression of these visual defects must be planned early in life, and the easiest way to achieve this is through the consumption of balanced nutrition.

Two carotenoids, lutein, and zeaxanthin, are antioxidants that the body deposits in the macula of the eye to create a protective layer called the macular pigment. These pigments filter out harmful blue light from our eyes and protect it from the risk of visual impairment. Our body cannot synthesize these nutrients naturally, so the only way to get these nutrients is through diet or supplements.

Visual defects in which lutein and zeaxanthin may help

  • Age-related macular degeneration (AMD): Consumption of these nutrients can help protect against AMD progression

  • Cataracts: Helps in slowing down the formation of cataracts.

  • Uveitis: Lutein and zeaxanthin may help reduce the inflammation in the middle layer of the eyes.

Please note: Most of the studies conducted on lutein and zeaxanthin show promising results in the eye defects. However, few studies found no link between lutein and zeaxanthin intake and AMD.

Despite this, the relevance of lutein and zeaxanthin for eye care and health cannot be ignored. Here are a few benefits of these magical carotenoids for eyes.

Benefits of lutein and zeaxanthin
  • Helps in prevention OF JUVENILE Macular Degeneration – The genetic eye defect in which a child’s macula starts deteriorating and results in blurred central vision may be reduced with the consumption of lutein and zeaxanthin.

  • Improvements in visual function – The ingestion of lutein supplements for 12 weeks has shown to promote improvements in visual function. It also helps in the treatment of vision problems due to long-term exposure from computer screens.

The Age-Related Eye Disease (ARED) can be considerably controlled, prevented, or delayed with the intake of zinc, copper, vitamin C, vitamin E, omega-3 fatty acids and most importantly with the consumption of lutein and zeaxanthin food sources.

Zeaxanthin and lutein consumption

The Recommended Dietary Allowance (RDA) or Recommended Daily Intake (RDI) for lutein and zeaxanthin has not been identified; however, a close approximate is available for consideration. Here are some important things that’ll help you decide the quantity – Experts suggest consumption of 6-20 milligrams (mg) of lutein, while some other studies suggest 10 mg of lutein and 2 mg of zeaxanthin per day for reduced risk of eye impairment. The amount of beta-carotene requirement is directly related to the stress levels your body endures. For instance, smokers may need more in comparison to non-smokers.Healthy fats such as olive oil, butter, or coconut oil help in the absorption of lutein and zeaxanthin.

We recommend increasing the intake of all the lutein and zeaxanthin-rich food in your diet. It also makes sense to include dietary supplements from the reputed source to ensure meeting your daily requirement for maintaining the health and beauty of your eyes.
