The Role of Eggs in Cataract Prevention: Boosting Immunity and Protecting Eye Health

Recently, Spanish dietitian Ronan Araujo highlighted that eggs may play an important role in preventing cataracts. Eggs are not only a tasty food but also a vital source of nutrients beneficial for eye and overall health.

Health Benefits of Eggs

Many believe eggs are high in cholesterol and harmful to health. However, recent studies show this view is outdated, and eating one or two eggs per day is safe and healthy.

  • Protein Source: Eggs are rich in high-quality protein that supports metabolism and muscle repair.

  • Micronutrients: Eggs contain phosphorus, zinc, and selenium — antioxidants that strengthen the immune system.

  • Lutein — Eye Protector: Eggs are a good source of lutein, a plant pigment crucial for eye health. Lutein is present in the iris and vascular layer of the eye, protecting against damage and reducing cataract risk.

Causes of Cataract and the Role of Eggs

Cataracts mostly develop due to aging, characterized by clouding of the lens that impairs vision. Research shows antioxidants like lutein can slow cataract progression or prevent its development.

Eggs provide lutein and other nutrients that help maintain immunity and overall health.

How to Include Eggs in a Healthy Diet?

Ronan Araujo advises:
“Eating one or two eggs daily as part of a varied diet provides significant health benefits. The benefits come from both the nutrient content and regular, moderate consumption.”

Eggs do not increase cardiovascular risk when consumed properly and may even reduce it.

Eggs are not just food but essential for eye health and immunity. Thanks to lutein and other antioxidants, they play a significant role in cataract prevention. Therefore, don’t hesitate to include eggs in your diet for better health and vision.
