Vitamin A is a general term for a group of fat-soluble compounds that are important for human health, the benefits of Vitamin A to the body are super awesome.
They are needed for many processes in your body, including maintaining healthy vision, ensuring proper functioning of the immune system and organs, and promoting proper growth and development of babies in the womb.
Benefits Of Vitamin A
Vitamin A aids the eyes, immune system, and organs function properly.
It is obtained through animal and plant-based foods.
Vitamin A helps the immune system
Vitamin A is necessary for your immune system to grow, maintain and strengthen the epithelium and mucosal tissues that underlie most of our organs.
These tissues are the body’s first line of defense against pathogens and are a key part of the body’s innate immune response to infection.
Vitamin A also has antioxidant properties. Antioxidants prevent cellular damage in a process known as oxidative stress.
Continued cellular damage from oxidative stress can lead to chronic diseases such as cancer, heart disease, and vision loss.
Nevertheless, extra or supplemental vitamin A has not proven to be beneficial unless you are deficient in it. Nonetheless, plant-based diets high in vitamin A are the best for you, according to most nutrition experts.
Vitamin A aids good vision
Vitamin A is important for maintaining night and blurred vision because it forms pigments in your eyes, the molecules that help you see color, which are essential for night vision.
Without vitamin A, your eyes stop producing these pigments, which can eventually lead to night blindness. This condition causes difficulty adapting to dim light or a complete inability to see in the dark.
“Vitamin A also plays a role in protecting the cornea, the transparent outer layer of the eye.
It can reduce the risk of cataracts, which cause blurry vision,” says Julienne Hever, MS, RD, CPT, a registered dietitian specializing in plant-based nutrition based in Southern California.
Cataracts are a common eye disease that affects more than half of people in the U.S. over the age of 80.
According to an eye disease study sponsored by the National Eye Institute, vitamin A supplements — in addition to other vitamins containing antioxidants and zinc — can protect eye health in people with certain diseases.
The study included 4,757 people between the ages of 55 and 80 with cataracts, age-related macular degeneration or both.
Age-related macular degeneration is a condition that causes loss of central vision, meaning that details in objects directly in front of a person may appear blurred.
Vitamin A helps in the treatment of acne
A type of vitamin A available by prescription or in small doses in anti-acne medications called retinol is considered one of the best topical treatments for acne.
In fact, acne care and treatment guidelines published in the Journal of the American Academy of Dermatology suggest the use of topical retinoids or retinol products as a first-line treatment for mild to severe acne.
Acne usually occurs when pores in the skin become clogged with dead skin cells and oils.
Retinol treats acne by acting as an extreme exfoliator, removing these dead skin cells and, in turn, promoting new cell growth, a process called cell turnover.
Topical retinol can be harsh on the skin, as common side effects are itching, redness or dryness. Some ways to reduce irritation include:
- Applying one thin layer of retinol instead of thick layers or multiple applications
- Apply a cream or gel every other day for the first two to four weeks.
- Using a gentle moisturizer.
- Be sure to apply sunscreen to your skin whenever you use retinol products, as they make you more prone to sunburn and sun damage. Learn more about how to find the right facial sunscreen for your skin type.
