Vitamin A or retinol is a fat-soluble vitamin that plays an important role in ensuring healthy eyes and bone development. Its deficiency is the most common cause of blindness among children. It can prevent night blindness and dry eyes, while also ensuring clear vision.

Important Sources of Vitamin A

Cod liver oil, cream, egg yolk, beef liver, cheddar cheese, fortified milk, and butter products are rich sources of vitamin A. Clare Gilbert from the London School of Hygiene and Tropical Medicine, in her extensive research on vitamin A, suggests that yellow or orange-colored fruits and vegetables, like yellow maize, that contain the pigment carotene are also great sources. Be sure to include food items such as sweet potato, carrots, broccoli, spinach, mango, pumpkin, tomato, oatmeal, apricot, peach, peas, papaya, and collard greens in your daily diet to ensure a regular supply of vitamin A.

Vitamin A Deficiency Symptoms

The major deficiency symptoms of vitamin A include keratinization of the skin, night blindness, a burning sensation or itching in the eyes, inflammation of the eyelids, xerophthalmia (dryness of the conjunctiva), dull lusterless hair, dandruff, brittle nails that break easily, sexual disorders, and precancerous changes in the body tissues. A deficiency of this vitamin may also result in fatigue, insomnia, and depression.

Health Benefits of Vitamin A

Vitamin A is essential for a healthy body and it has many beneficial properties, including those listed below.

Strengthens Immunity

Vitamin A enhances the body’s immunity against infections by increasing the lymphocytic responses against disease-causing antigens. It keeps the mucous membranes moist to ensure better immunity and also enhances the activity of white blood cells. It not only prevents germs from entering your body but also helps fight the infections once the germs gain entry into the body, thereby ensuring a double core protection.

Improves Vision

Vitamin A can aid in improving vision. It enables your eyes to adjust to light changes, keeps them moist, and also improves night vision. It can prevent many conditions like dry eyes and night blindness by increasing the adaptability of the human eye to both bright light and darkness. Retinol helps in the formation of visual purple in the eyes, which can improve the eyes and ensure a healthy retina. It can also significantly cut down the risk of cataract and macular degeneration, which is commonly associated with aging. It is also thought to be beneficial for people suffering from glaucoma.
