Vitamin A is one of the important elements needed to support various bodily functions. But unfortunately, this vitamin can not be produced by the body, you must meet their needs through food sources. That way, we can be sure you will get many benefits of vitamin A.
What are the benefits of vitamin A for health?
You can meet your daily needs for vitamin A from various food sources. Ranging from fish, liver, eggs, milk, cheese, carrots, spinach, broccoli, sweet potatoes, melons, papaya, mangoes, and so forth.
Because of its very important role, the daily intake of vitamin A recommended by the Ministry of Health in Nutrition Adequacy Rate (RDA) is as much 500 micrograms (mcg) for adult women and 500 micrograms (mcg) for adult men.
The following are the various benefits of vitamin A for body functions that you will get:
1. Maintain eye health
One of the most famous benefits of vitamin A is its ability to maintain the function of your vision. Vitamin A here has the important task of converting light captured by the eye into electrical impulses to be delivered directly to the brain.
If your body is deficient in vitamin A, you may experience night blindness as an initial symptom. This happens because the retina of the eye, which should catch the light coming, lacks its constituent material in the form of rhodopsin. Vitamin A is the main component producing rhodopsin pigment.
Not surprisingly, many people with night blindness are difficult to see clearly at night due to decreased retinal function. In addition to preventing night blindness, meeting the needs of vitamin A which is a source of beta carotene can help slow the decline in vision with age.
2. Strengthens the immune system
Easy to fall sick on the sidelines of a busy schedule? Maybe you lack vitamin A. The reason is, vitamin A has an important role in maintaining your body's natural defenses. It includes optimizing the function of the lungs, intestines, and other organs of the body from attacks of bacteria that cause infection
Vitamin A is also directly involved in the production and work of white blood cells, to help attack foreign pathogens that enter the body.
This means that a body that is deficient in vitamin A will be very susceptible to infection and difficult to recover while being sick, reported the Annual Review of Nutrition Journal.

3. Supports fetal growth
Other benefits of vitamin A are important for the health of the male and female reproductive systems. In fact, vitamins that are classified as fat soluble are also good for supporting the development of the embryo during pregnancy.
Adequacy of vitamin A that must be fulfilled by pregnant women will complete the body structure of the fetus, including the heart, kidney, eyes, lungs, pancreas to the body frame. Even so, pregnant women should still monitor the intake of vitamin A that enters the body. Too much vitamin A can also harm the fetus in the mother's stomach.
We recommend that you meet the needs of this vitamin to taste, not less or more, which can actually endanger the health of the body.
4. Prevent pimples from appearing
Uniquely, vitamin A turns out to have a special relationship with acne, you know. Yes, this vitamin includes important nutrients that can help eradicate stubborn acne and even prevent it from appearing.
This is because when the level of vitamin A in the body is low, the production of keratin (natural protein in the hair) will increase rapidly to exceed its optimal limit.
This condition then makes the production of oil on the skin more so that it clogs the pores of the skin and triggers acne.
5. Maintaining bone health
Vitamin D and calcium are some of the key nutrients that can maintain bone function as we age. But what you might not know is that vitamin A also has an important role in bone development. This vitamin is often associated with even worse bone condition.
The statement is supported by research published in the International Journal of Environmental Research and Public Health, that people with low levels of vitamin A are at risk of experiencing fractures that are much higher than those who can meet vitamin A needs well.
