Food: Variety and Sources

Our country is so diverse in culture, customs and languages and so on. Most fascinating one is the diversity in the food we eat. From state to state, from time to time, the food we eat varies. The food we eat today is different from tomorrow. Hence, it’s time to think and learn about “Where does it come from?”. Let’s have a glimpse of food variety, their sources and diet of animals.


As we said, food comes in a variety of forms, each come from different sources. Some we eat directly like fruits, whereas some we cook and eat like curry, rice, kheer, etc. Whether it is cooked or uncooked , the main sources of anything we eat are plants and animals. Fruits, vegetables, pulses, grains, etc. come from plants. Milk, eggs, meat and other dairy products come from animals.

Plants as source

Most of the parts of plants such as leaves, flowers, roots, stems, are edible. Carrots, beetroot, radish are some root vegetables; spinach, cabbage are leafy vegetables; tomato, brinjal, lady’s finger are few fruit vegetables. But, every part of every plant is not consumable; sometimes they can be toxic and allergens.

Animals as source

They give us milk, eggs, meat and many other products like cheese, ghee, honey, etc. Animals depend on plants for their food. Hence, we can assert that “directly or indirectly plants are the primary producers and primary source of food”.
