Researchers might argue that what humans expend in their bodies is what ultimately leads to their good health. It is certainly true that whatever you consume will have a significant impact on your metabolism. What really matters in this process, however, is how humans think throughout their lifelong journey. Their mindset determines the choices they make every 24-hour day of every week. Choices are what lead humans to become obese. This essay does not imply that humans choose to become obese; however, it mainly points out that people continually make bad decisions that lead them to be overweight. This can result from a lack of knowledge and understanding. This essay will discuss how important knowledge is to achieving good health outcomes and how this compares to the psychological mindset of how people think about their choices. Imagine that we are told nothing about the food that is put into our bodies and that from now on we will have to rely only on experience rather than the word of mouth of others to live on an adequate diet. Can individuals live on a sufficient diet without having in-depth knowledge of food, nutrition and water? Can knowledge be an obstacle? Furthermore, why do people make the decisions they do when consuming certain foods at a certain time? Experience, choices and nutritional knowledge are three factors that contribute to a person's level of understanding of a healthy diet. Nutritional knowledge is absolutely essential for working people who are expected to know how food affects society. However, people, in general, do not have everything to gain from surfing the web and searching for facts that might benefit them for their own good. It's... half of the paper... tries to get us to make good or bad choices. Works Cited Taubes, Gary. (2012, June 30). What really makes us fat.
