What are the physiological functions of food? Answer briefly.
The physiological functions of food are essential for sustaining life and maintaining health. These functions include:
Providing Energy: Food supplies the body with calories (energy) derived from carbohydrates, fats, and proteins. This energy is utilized for various bodily functions such as metabolism, movement, and maintaining body temperature.
Supporting Growth and Repair: Foods contain essential nutrients like proteins, vitamins, and minerals that support growth and repair of body tissues. Proteins are crucial for building and repairing muscles, while vitamins and minerals play roles in bone health, immune function, and many other physiological processes.
Regulating Body Functions: Foods contain substances that help regulate bodily functions, such as electrolytes (sodium, potassium) for nerve and muscle function, and water for hydration and temperature regulation.
Maintaining Health: Certain components of food, such as antioxidants in fruits and vegetables, help protect against oxidative stress and reduce the risk of chronic diseases like heart disease and cancer.
Overall, food provides the necessary components for life, growth, repair, and overall well-being of the body.
