Both the alphabet and good nutrition begin with A.
Vitamin A is one of the building blocks of a healthy body and strong immune system.
Vitamin A is sometimes referred to as retinyl acetate or palmitate. It is crucial for forming and maintaining healthy teeth and skin. In addition, it plays an important role in maintaining mucous membranes, skeletal tissue and soft tissue.
A deficiency in vitamin A is caused by dietary issues.
One of the first symptoms of a vitamin A deficiency is a spell of night blindness.
A deficiency in vitamin A can also lead to overall impaired vision, liver disorders and rashes.
A long-term deficiency can interfere with nutrient absorption that may be connected to celiac disease, chronic diarrhea, giardiasis and cirrhosis.
An excess of vitamin A is also caused by diet.
Taking in too much vitamin A can create some negative health consequences.
Having too much of this vitamin in your blood could result in bone loss, thinning hair, dry skin, severe headaches and weakness. Stomach pain, nausea and vomiting are some of the immediate results of taking too much vitamin A.
The recommended daily intake of vitamin A varies greatly by age.
The benefits of Vitamin A for humans were recognized in 1912 when an English biochemist discovered that there were factors present in milk that aided with the growth of rats in experiments.
