Scientific analysis of food and nutrients began during the chemical revolution in the late 18th century, marking the birth of nutritional science. Today, the question of what is the scientific definition of nutrition refers to the biochemical and physiological processes through which an organism uses food to support its life functions. This encompasses far more than just eating, involving digestion, absorption, metabolism, and excretion.

According to the Food and Agriculture Organization of the United Nations, hunger is an uncomfortable or painful physical sensation caused by insufficient consumption of dietary energy. Delving deeper, the scientific definition of hunger is a complex psychobiological state driven by an intricate network of physiological and neurological signals, designed to motivate food consumption and maintain the body's energy balance.

Unlike the protected title of 'dietitian' in many regions, the legal definition of nutritionist varies dramatically, meaning qualifications can range from self-taught to a PhD. This disparity highlights why understanding the scientific definition of nutritionist is crucial for anyone seeking expert nutritional guidance.
