Food and Nutrition
People think that food and nutrition mean the same thing, they don’t. Food refers to the plants and animals we consume. These foods contain the energy and nutrients our bodies need to maintain life and support growth and health. Nutrition, in contrast, is a science. Specifically, it is the science that studies food and how food nourishes our bodies and influences our health. It identifies the processes by which we consume, digest, metabolize, and store the nutrients in foods, and how these nutrients affect our bodies. Nutrition also involves studying the factors that influence our eating patterns, making recommendations about the amount we should eat of each type of food, maintaining food safety, and addressing issues related to the global food supply. When compared with other scientific disciplines such as chemistry, biology, and physics, nutrition is a relative newcomer.
