Natural sources of vitamins for the eyes

Natural sources of vitamins for the eyes: a comprehensive guide to nutrition for visual health

Eye health is a precious gift that requires constant attention and care. In the modern world, where vision is constant for a constant load from screens, poor ecology and malnutrition, maintaining the optimal function of the eyes becomes especially important. One of the key factors for maintaining the health of the eyes is proper nutrition, rich in vitamins and trace elements. In this article, we will examine in detail the natural sources of vitamins necessary for maintaining and improving vision, their influence on various aspects of the eyes of the eyes and ways to include them in your diet.

Vitamin A: Foundation for the health of the cornea and twilight vision

Vitamin A plays a critical role in maintaining the health of the cornea, a transparent outer shell of the eye, as well as in ensuring normal twilight vision. It is part of Rhodopsin, a photosensitive pigment that allows us to see in low light conditions. Vitamin A deficiency can lead to serious problems, such as the dryness of the cornea (xerophthalmia), chicken blindness (nickthalopia) and even blindness.

Sources of vitamin A:

• Retinol (active form of vitamin A):
  • Liver: Beefs, chicken and fish liver is one of the richest sources of retinol. However, liver use should be limited due to the high cholesterol content.
  • Dairy products: Whole milk, butter, cheese and eggs contain retinol, but in smaller quantities than the liver.
  • Fish oil: Another excellent source of retinol and omega-3 fatty acids, which are also useful for the health of the eyes.
• Provitamin A (beta-carotene): The body transforms beta-carotene into retinol.
  • Orange and yellow fruits and vegetables: Carrots, pumpkin, battery, mango, apricots and melon are rich in beta-carotene. Carrots are a classic example, and its beneficial properties for vision are well known.
  • Green sheet vegetables: Spinach, cabbage, broccoli and salad Roman also contain beta-carotene. Although they are green, they hide a significant amount of provitamin A.
  • Red pepper: Red Bulgarian pepper is another good source of beta-carotene.

The influence of vitamin A on the health of the eyes:

• Maintaining the health of the cornea: Vitamin A is necessary to maintain the integrity and moisturize the cornea, preventing dryness and irritation.
• Improving twilight vision: Vitamin A is part of the rhodopsin, ensuring the adaptation of the eyes to the darkness and improving visibility in low illumination conditions.
• Protection against age -related macular degeneration (VMD): Some studies show that vitamin A can play a role in the prevention of the VMD, although additional studies are required to confirm this effect.
• Reduction of risk of cataract development: The antioxidant properties of vitamin A can help protect the lens of the eye from oxidative stress, reducing the risk of cataracts.

How to include vitamin A in the diet:

• Diversify your diet: Include various products rich in both retinol and beta-carotene in your diet.
• Cook correctly: When preparing vegetables, try to use methods that preserve nutrients, such as steaming or baking.
• Add fats: Beta-carotene is better absorbed when consumed with a small amount of fat. For example, season carrots with olive oil or add avocado to a salad with spinach.
• Consult a doctor: If you suspect a deficiency of vitamin A, consult a doctor to determine the optimal dosage and choose suitable additives.

Vitamin C: A powerful antioxidant to protect the lens and retina

Vitamin C, or ascorbic acid, is a powerful antioxidant that plays an important role in protecting the eyes from damage caused by free radicals.
