Final answer:
Vitamin A is essential for healthy skin and body linings. Deficiency can lead to dry skin, weakened immune response, and visual impairments. Consuming foods rich in vitamin A can help prevent deficiency.
Step-by-step explanation:
Vitamin A is essential for healthy skin and body linings. Without enough vitamin A, your skin can become dry, rough, and prone to infections. Your body linings, such as the lining of your respiratory system and digestive system, can also be affected, leading to a weakened immune response and increased susceptibility to infections.
For example, vitamin A deficiency can cause visual impairments, including night blindness. It can also contribute to anemia, as well as affect the development of the immune system in young children.
To prevent vitamin A deficiency, it is important to consume foods rich in vitamin A, such as carrots, sweet potatoes, and leafy green vegetables.
