What is food? Explain the functions of food in our body?
Food is any substance consumed to provide nutritional support for the body. It contains essential nutrients such as carbohydrates, proteins, fats, vitamins, and minerals that our bodies require for growth, maintenance, and repair. The functions of food in our body are crucial:
Energy Production: Carbohydrates and fats are primary energy sources. They are converted into glucose and fatty acids, providing fuel for cellular activities.
Growth and Repair: Proteins are essential for building and repairing tissues like muscles, organs, and skin.
Regulation of Body Functions: Micronutrients like vitamins and minerals act as cofactors for various enzymatic reactions and help regulate metabolism.
Immune Function: Certain nutrients support the immune system, aiding in defense against infections.
Maintenance of Body Functions: Water and electrolytes maintain fluid balance, while fiber aids digestion and prevents constipation.
In summary, food serves as the body's fuel, building blocks, and regulators, ensuring optimal health and function.
