Vitamin A promotes eye health, but not only that, it is also very important for the immune system. According to Nutrition Source, vitamin A stimulates the production and activity of white blood cells, participates in bone remodeling, and regulates cell growth and division necessary for reproduction.
The National Institutes of Health (NIH) indicates that vitamin A also helps the heart, lungs, and other organs function properly. When you are not consuming enough vitamin A, the body can send you several signals.
1. Difficulty seeing in low light
According to the Office According to the NIH Dietary Supplements, the most common sign of vitamin A deficiency is an eye condition called xerophthalmia. Xerophthalmia is the inability to see in low light and can lead to blindness if left untreated.
2. Dry skin
With vitamin A deficiency, the skin may lack a key nutrient that helps repair the skin. Which can result in the experience of having dry, flaky skin, according to nutritionist Lauren Manaker Manaker via Well+Good.
3. Weak immune system
The NIH indicates that a long-term deficiency of vitamin A can also lead to an increased risk of respiratory diseases (such as pneumonia) and infections.
4. Wounds take time to heal
Although vitamin C is one of the most important nutrients that helps in wound healing, vitamin A also plays a role in the synthesis of collagen and with it in the ability to heal wounds.
5. Anemia
Vitamin A deficiency can also cause anemia (a condition in which red blood cells do not supply the body with enough oxygen). “In severe cases, not getting enough vitamin A can increase your chances of dying,” the NIH shares.
Vitamin A is a fat-soluble vitamin that is naturally present in many foods such as:
-Some types of fish, such as herring and salmon.
The amount of vitamin A a person needs depends on age and sex. An adult woman requires 700 micrograms (mcg) and an adult man requires
For reference, half a cup of boiled spinach provides 582 mcg of vitamin A. One serving of liver (3 ounces) provides 6.582 mcg of vitamin A, equivalent to 700% of the recommended daily intake. It is just because of its richness in this vitamin that the consumption of this organ meat should be limited to small amounts.
The body stores excessive amounts of vitamin A. Regular and abundant consumption of liver can cause vitamin A toxicity, called hypervitaminosis A.
