What are the benefits of foods that contain vitamin A?

Known for its ability to maintain eye health, vitamin A is also needed by the body for immune system function, reproduction, and communication between cells. Another benefit of vitamin A is to support cell growth and division, maintain heart, lung, and kidney function. The best source of vitamin A intake can be obtained from daily food.

1. Slow down and prevent night blindness

Vitamin A is needed to convert light that enters the eye into nerve signals that will be sent to the brain. Beta carotene contained in vitamin A is able to slow down the occurrence of eye degeneration and prevent night blindness by maintaining the function of the rhodopsin pigment in the retina.

2. Helping skin care

Another benefit of this vitamin is to maintain health and help the growth of hair and skin. This vitamin helps keep the skin and hair moisturized by helping the production of sebum or oil.
In the world of dermatology, retinoids are known as one of the ingredients commonly prescribed by doctors to treat various skin problems such as acne. For its own use, this retinoid drug can be applied directly to problematic skin or taken by mouth.

3. Boost immunity

The body naturally has an immune system that can fight various diseases that come. Vitamin A helps stimulate the immune system response and is involved in the formation of immune cells, including B and T cells that act as body armor against disease-causing microorganisms.
Vitamin A also plays an important role in the production and function of white blood cells that help fight disease pathogens in the blood. Hence, a lack of vitamin A can make a person’s body susceptible to illness and the healing process is slow.

4. Supports cell growth

The role of vitamin A is no less vital is to help maintain the health of important organs such as the heart, lungs, and brain by optimizing the process of cell growth and division.
Vitamin A also functions to maintain cell shape. So a lack of vitamin A can cause the shape of epithelial cells to be flat and not formed properly.

5. Supports fetal development

Regular consumption of vitamin A is highly recommended for pregnant women. Why is that? This is because vitamin A is able to strengthen various body tissues in the fetus such as muscles, heart, brain, and others.
Vitamin A is also essential for the male and female reproductive systems because of its role in the development of sperm and egg cells.

6. Lowering the risk of cancer

In some studies it is known that consuming vitamin A regularly from vegetables can reduce the risk of cancer. Because of the antioxidants contained in them, fruits and vegetables high in carotenoids can protect the body from the risk of certain cancers.

7. Help prevent diabetes

Consumption of foods high in beta carotene can help reduce the risk of diabetes and heart disease because, again, it contains antioxidants. Carotenoids can damage the chain of free radicals that cause oxidative stress to the body. This oxidative stress is associated with a variety of chronic diseases, including diabetes.

8. Treating measles

Lack of vitamin A intake can trigger several types of diseases, one of which is measles. The benefits that can be obtained from the consumption of vitamin A supplements in people with measles are intended to speed up the healing process. This is due to the role of vitamin A in boosting the immune system.
Even Sapna Patel and Michael Vajdy said, in their research, in countries with high cases of measles and malaria, treatment with vitamin A in children can reduce the risk of death from these diseases.

9. Supports bone health

Although the main nutrient for bone growth and development is vitamin D, vitamin A is also needed for rapid growth and development. Several studies have also shown that people who have low levels of vitamin A are at greater risk of fractures.

Main Source of Vitamin A

Vitamin A is included in the intake of micronutrients, namely nutrients that the body needs and must be met even in small amounts. Two forms of vitamin A are found in daily food, namely: (1) retinol and retinyl ester which are the active forms of vitamin A and are derived from animal products; (2) provitamin A carotenoids derived from plant and vegetable products.
Among the 3 other forms of provitamin A carotenoids, beta carotene is the most important for the body. Beta carotene will be converted into the active form of vitamin A before being converted back into retinal and retinoic acid in order to carry out their role in the body’s biological functions. It is different with lycopene, lutein, and zeaxanthin, which are not converted to vitamin A.
