Vitamin A is an essential nutrient that plays a crucial role in maintaining vision, immune function, and skin health. A deficiency in vitamin A can lead to various health problems, including impaired vision, immune dysfunction, and an increased risk of infections. Here are some ways to cure vitamin A deficiency
There are two types of vitamin A: preformed vitamin A (retinoids) found in animal sources, and provitamin A carotenoids found in plant sources. Here are some common sources of both type
1. Preformed vitamin A (retinoids):
- Liver (beef, chicken, pork, fish)
- Egg yolks
- Dairy products (milk, cheese, yogurt)
- Cod liver oil
2. Provitamin A carotenoids:
- Dark green leafy vegetables (spinach, kale, collard greens)
- Orange and yellow vegetables (carrots, sweet potatoes, pumpkin, butternut squash)
- Fruits (mangoes, apricots, papayas, cantaloupe)
- Some types of algae (spirulina)
IPreformed vitamin A, also known as retinoids, are a type of vitamin A that is found in animal sources. They include retinol, retinal, and retinoic acid, which are all active forms of vitamin A that the body can readily use.
Vitamin A deficiency diseases and their treatment
1. Night Blindness
Night blindness is one of the earliest signs of vitamin A deficiency. It is a condition in which a person has difficulty seeing in low light or at night. The treatment for night blindness involves increasing the intake of vitamin A through diet or supplements.
Xerophthalmia is a condition that occurs when the eye’s conjunctiva and cornea become dry and inflamed due to vitamin A deficiency. The treatment for xerophthalmia involves high doses of vitamin A supplements administered orally or by injection.
3. Bitot’s Spots
Bitot’s spots are small, white, foamy spots that appear on the conjunctiva of the eye. They are a sign of severe vitamin A deficiency. The treatment for Bitot’s spots involves high doses of vitamin A supplements administered orally or by injection.
Keratomalacia is a condition that occurs when the cornea of the eye becomes soft and cloudy due to vitamin A deficiency. The treatment for keratomalacia involves high doses of vitamin A supplements administered orally or by injection.
