Frequently Asked Questions
Why do we need a balanced diet?
We need a balanced diet because it provides all the essential nutrients, water, and roughage in the right amounts for proper growth and development.
How does refrigeration help in food preservation?
Refrigeration keeps food at a very low temperature, which slows down the growth of germs and bacteria that cause food to spoil.
What is the difference between energy-giving and body-building foods?
Energy-giving foods (like carbohydrates and fats) provide energy for our daily activities, whereas body-building foods (like proteins) help in growing taller, stronger, and repairing body parts.
