Deficiency Diseases and Their Impact on Health
Vitamins and minerals play a crucial role in maintaining overall health, and a deficiency in these essential nutrients can lead to various deficiency diseases. Some common examples include night blindness due to lack of Vitamin A, scurvy caused by Vitamin C deficiency, beriberi resulting from a lack of Vitamin B1, rickets caused by Vitamin D/Calcium deficiency, and anaemia due to Vitamin B12/Iron deficiency. Understanding the symptoms and sources of these nutrients is essential for preventing and managing deficiency diseases.
