It is a biologically known fact that, right since the first living organism breathed for the first time billions of years ago, it needed food to survive and grow. Food is something without which growth, development, and evolution would have been impossible. Every living thing on the face of the earth, irrespective of whether it belongs to the plant or animal kingdom, needs nutrition to survive, grow, and reproduce. All the living organisms on earth are therefore, dependent on each other for survival in some way or the other and that is what we call the ecosystem. The food chain in nature includes both plants and animals who are a part of it and even the tiniest ecosystem has a food chain for itself. Food is not only important for our survival, but when human beings are concerned, there are many other important points. Thus, find out the importance of food from the paragraphs mentioned below. ... For Survival As mentioned above, without food, there is no survival. Therefore, the answer for why is food important is that, when you consume some mode of food and nutrition, the body functions in a particular manner. Without a catalyst, there is no product that is formed and for all living things like plants, animals, and humans, certainly food is the catalyst. Hence, when you consume food, nutrition is provided to the body for the production of energy and in turn, the body is functional. The food pyramid gives us an idea about its value in our lives and how, in a very pictorial and clear manner. This is a very biological and medical purpose of food as you need it for the cycle of life. Charles Darwin also supported the importance of food through the theory of "survival of the fittest". ... To the Human Body The cycle of life consists of birth, growth, development, reproduction, and eventually death. For an individual to go from birth to death, there is a constant necessity for nutrition and catalyst which is provided by the food which is consumed. The human body is one of the most complicated creation of nature as every pathway related to it is designed very uniquely. These pathways work together to function all the major human body systems and in turn keep the body fit. There is also a need to know why is food safety important, as we cannot consume spoiled and perished food as the fuel for our bodies. Hence, if you have wondered, why is it important to eat healthy food, it is so that these pathways which control the systems work in the proper manner. The basic point of this explanation can be compared to the functioning of a vehicle which works best with good amount and quality of fuel, and breaks down when there are problems in its working. ... To Culture Apart from only keeping the body fit and healthy, food has other commercial importance too.
