Consider the following statements about deficiency diseases: 1. Deficiency diseases are those caused by the intake of excess fat over a short period. 2. Deficiency of Vitamin B1 causes a disease known as Beriberi. 3. Deficiency of Iron causes Anaemia. Which of the statements given above are correct?

Correct Option The correct option is (c) 2 and 3 only. Explanation Deficiency diseases are pathological conditions caused by the lack of essential nutrients-such as vitamins, minerals, proteins, or carbohydrates-in the diet over a prolonged period. They are not contagious and can usually be prevented or cured by consuming a balanced diet. Statement-wise Analysis - Statement 1 is Incorrect. Deficiency diseases are caused by the lack of nutrients over a long period, not by the intake of excess fat over a short period. Excess intake of fat typically leads to obesity or cardiovascular issues, which are lifestyle-related conditions, not deficiency diseases. - Statement 2 is Correct. Vitamin B1 (Thiamine) is essential for glucose metabolism and nerve function. Its deficiency leads to Beriberi, a condition characterized by weak muscles and very little energy to work. - Statement 3 is Correct. Iron is a critical mineral required for the formation of hemoglobin, the oxygen-carrying pigment in red blood cells. A deficiency in iron leads to Anaemia, which results in general weakness and fatigue. Key Takeaway Deficiency diseases arise from the prolonged absence of specific nutrients in the diet. Common examples include Scurvy (Vitamin C), Rickets (Vitamin D), Beriberi (Vitamin B1), and Anaemia (Iron).
