Sources of Food
We get our food from two main sources: plants (fruits, vegetables, grains) and animals (milk, eggs, meat, honey).
Food Spoilage
Food goes bad or spoils when tiny organisms like bacteria and fungi grow on it, making it unsafe to eat and changing its smell and taste.
Food Preservation
Methods like drying, freezing, pickling, and adding sugar or salt help preserve food for a longer time by stopping germs from growing.
Balanced Diet
A balanced diet contains the right amounts of different nutrients like carbohydrates, proteins, vitamins, and minerals that keep our body healthy and strong.
Avoiding Food Wastage
Wasting food is harmful because millions of people go hungry; we should only take as much food as we can eat and store leftovers properly.
