🍎 About Food – Importance, Types & Functions
Food is the basic necessity of life. It provides the essential nutrients required by the body to grow, develop, function, and stay healthy. Every living organism, from a single-celled microbe to a human, depends on food for energy, growth, repair, and maintenance of body functions.
Food is made up of macronutrients (like carbohydrates, proteins, and fats) and micronutrients (like vitamins and minerals). Additionally, water and dietary fiber play crucial roles in digestion and overall health.
There are different types of food based on their function:
-
Energy-giving foods – Carbohydrates and fats (e.g., rice, oil, butter)
-
Body-building foods – Proteins (e.g., eggs, pulses, meat)
-
Protective foods – Vitamins and minerals (e.g., fruits, vegetables, milk)
A balanced diet includes all of these nutrients in proper amounts. Deficiency or excess of any nutrient can lead to health problems, such as malnutrition, obesity, or deficiency diseases like scurvy, rickets, goitre, and anemia.
Understanding food and nutrition is vital not just for personal health, but also for addressing global issues like hunger, food safety, and lifestyle diseases. This quiz will test your deep understanding of food science and help you prepare for competitive exams.
