INTRODUCTION

Diet is the term used in nutrition to describe the foods and drinks that a person (or a group) consumes on a daily basis.

​

Apart from health reasons, nutrition can also be influenced by religious beliefs and personal preferences. Humans in general eat an omnivorous diet. However, some people tend to be selective to certain types of food. This selective dietary behaviour led to various types of diets, which can be classified based on the kind of food that are habitually or preferentially consumed. Examples of diets are: carnivorous diet, vegetarian diet, vegan diet, omnivorous diet, etc.
