Final answer:
Vitamin A deficiency symptoms mainly include night blindness and visual impairments, can affect the immune system, and may lead to anemia. Vitamin A can be synthesized from beta-carotene and is critical for health.
Step-by-step explanation:
Symptoms of vitamin A deficiency include night blindness and visual impairments, which can progress from difficulty seeing in low light to complete blindness. In young children, this deficiency can significantly impair the development of the immune system, making them more vulnerable to infections. Moreover, vitamin A deficiency can also contribute to anemia. Your body can synthesize vitamin A from beta-carotene, a pigment that gives carrots their orange color. For healthy skin, bones, teeth, and particularly for good vision, vitamin A is essential. Foods rich in vitamin A or beta-carotene are critical to preventing deficiencies and maintaining good health.
