Nutrition is important for good health, but healthy nutrition is not the same for everyone. As a result of differences in the way individuals absorb and utilise food, targeted adjustments of the food they ingest can lead to health benefits for the elderly, children, or patients with metabolic disorders, for example. A better understanding of the availability of nutrients in the human body is important to be able to tailor improvements in nutrition. In combination with this knowledge about nutrition, chemistry is crucial for the production of better food. In-depth biochemical knowledge of nutrition, as well as chemical knowledge of the processing and packaging of food, will also lead to a more efficient use of crops and raw materials in our food supply.
