Food is the fuel which runs the body. Food provides all the nutrition the human body needs. It is generally of either plant or animal source. Food is a rich source of essentials such as carbs, fatty acids, proteins, natural vitamins, or minerals.
Food consists of:
Anything else that is eat-able and digestible and nutritious. Many food types can be had raw such as fruits and vegetable salads. Fruits are a great source of vitamins while vegetable salads are a great source of minerals, in general. Greens and meat is generally considered to be the best sources of proteins while chicken and eggs too provide proteins and carbs. Sea food is again rich in all kinds of nutrients and is a regular diet along the seaside regions of the world.
Cooking helps raw food to remain in an edible state for an extended duration. In cooking, one adds preservatives such as salt and spices to enhance the flavors and the aroma. Cooking also, helps retain nutrients for a longer duration and the preservatives help in avoiding the food from turning stale and rotten. Cooking allows us to eat food in a healthy way and eat those kinds of food which are otherwise inedible especially sea food and various meats.
