Question 1. What does Vitamin imply? Name different vitamins.
Answer: Vitamins are organic chemical compounds that contain hydrogen, carbon, and oxygen. They help keep the body healthy and fit, acting as regulators that assist the body in using other nutrients. Initially, people believed that only proteins, carbohydrates, fats, water, and mineral salts were needed for the body. However, experiments in 1881 proved that many more nutrients, known as vitamins, are vital for human survival. Even though vitamins are needed in small amounts, they are crucial for good health. A deficiency of vitamins can lead to many diseases. Some vitamins dissolve in water, while others dissolve in fats. If our food lacks vitamins, the body loses its ability to fight off germs, and bones, teeth, and eyes can develop problems.
In simple words: Vitamins are special compounds that keep our bodies healthy and help other nutrients work. We need them in small amounts to fight sickness and prevent problems with our bones, teeth, and eyes.

🎯 Exam Tip: Define vitamins as essential organic compounds needed in small quantities for health and proper body function, and mention the consequences of their deficiency.

Question 2. Why do we eat food?

Answer:
**Proteins:** Proteins are made of carbon, hydrogen, oxygen, nitrogen, sulfur, and mineral salts. They are found in foods like milk, eggs, butter, curd, maize, wheat, meat, fish, soybeans, peas, pulses, cheese, carrots, almonds, and cabbage. Proteins boost mental energy and help produce digestive juices. They build new tissues, repair damaged ones, and give the body immunity to fight diseases. Proteins are very important for children, pregnant women, and breastfeeding mothers.
**Carbohydrates:** Carbohydrates are compounds of carbon, hydrogen, and oxygen. A healthy person needs about 500 grams of carbohydrates daily. Carbohydrates provide heat and energy to the body, help maintain body temperature, and assist in building muscles. They are found in foods such as rice, wheat, maize, barley, potatoes, turnips, carrots, peas, arrowroot, yams, arabi, sago, jowar, bajra, almonds, cashews, mangoes, bananas, sugarcane, and dates. They are our body's primary energy source.
