Types of Food

What is food??  
Food can be defined as anything under earth which is eaten by living organisms to provide nutritional support for the body or for pleasure. Life cannot exist without food. 

Food performs three functions in our bodies, namely:
a) it serves as building blocks
b) it provides energy
c) it provides protection
 
There are various types of food , which can be categorized based on taste, countries, availability and so on.
Broadly we classify food as 

Vegetarian food: Vegetarianism is the practice of following a plant-based diet including fruits, vegetables, cereal grains, nuts, and seeds, mushrooms.

Non – Vegetarian food: 1. Food is obtained partly or wholly from a living animal.
2. The animal is deliberately killed even it could most likely survive.

Food differs from place to place depending on the culture, tradition and the availability. For example we have sea food for coastal areas which includes lot of marine fish, desert food which includes meat and so on. 

We will learn more about food chain and its structure in future blogs.
