The Functions and Precautions of Vitamin A

The health information we are presenting today is about vitamin A.


Benefits of Vitamin A

Vitamin A is contained in animal foods, and vegetable foods contain a form called carotenoid, which is converted to vitamin A in the body. Vitamin A is essential to maintain three basic functions: eye health, growth and development, and immunity. Vitamin A is also needed to build and maintain skin and mucous membranes, and is a necessary nutrient for cell growth and development, helping to prevent aging delays, anti-cancer effects, and diabetes complications, as well as promoting lung function, and preventing cancer and heart disease.

Carotenoid ingredients, which are converted to vitamin A, also have special benefits. Typically, beta carotene has a delay in aging, anti-cancer effects, diabetes, preventing complications, and promoting lung function. Beta-carotene, especially in its natural state, is more potent in its antioxidant properties. Lutein is closely related to eye health, such as preventing cataracts and macular degeneration and delaying the rate of visual degeneration.

If You Consume It Too Less

Meanwhile, a lack of vitamin A causes problems for your body. First of all, night blindness with reduced night vision. It also worsens eye health, including dry eyes and corneal softening and macular degeneration. In addition, the cells gradually become harder and drier, resulting in roughened skin, more dead skin cells, and follicular keratosis. Loss of mucus secretion in the body, making it easier for bacteria to get in, lowering thyroid function, lowering immunity, and eventually significantly reducing the ability to fight cancer.

If You Consume It Too Much

Vitamin A is a fat-soluble vitamin, which is absorbed differently from the water-soluble vitamin, vitamin b or c, and leftovers are stored in the adipose  tissue and liver without being drained into the urine. If the amount accumulated in your body is too excessive or if you suddenly consume too much, you may experience hypertension and toxicity. Excess symptoms may include fatigue, headache, nausea, diarrhea, vertigo, weight loss, itching, and in severe cases, brain and liver damage. Studies have also shown that overdose by pregnant women can cause stillbirths or birth defects in the fetus, and overdose by smokers can increase the incidence of lung cancer.

However, this is especially true if you consume too much artificially, such as continuing to consume more than five times your intake limit for a long period of time, or if you suddenly consume more than 100 times the amount at a time. In general, eating a properly balanced diet of vegetables and meat is not a concern, but you should be careful about taking vitamin A through nutritional supplements.

Be sure to check your vitamin A content, especially if your child is taking long-term multivitamin medications for adults, as they may exceed the maximum allowed amount of vitamin A. But by nutritional standards, the recommended daily intake of vitamin A in adults is 750 micrograms for men and 650 micrograms for women, and according to the Ministry of Health, more than 70 percent of people do not consume the recommended amount of vitamin A. So rather than worrying about overdose, it’s better to eat foods that have vitamin A in them.

Animal foods high in vitamin A include eggs, dairy products, liver and fish oil; vegetable foods include green and yellow vegetables and fruit nuts; and they are also rich in seaweed, such as steam and seaweed.
