Nutrients are defined as components in food that are essential to good health because they provide the necessary substances that the body needs to function properly. These nutrients play critical roles in various bodily processes, including growth, metabolism, and maintenance of bodily functions. They are categorized into macronutrients, such as carbohydrates, proteins, and fats, which are needed in larger amounts, and micronutrients, such as vitamins and minerals, which are required in smaller amounts but are equally important for health.

In contrast, flavor enhancers and additives do not provide essential health benefits and typically serve to improve the taste or shelf-life of food without contributing directly to nutritional value. Ingredients used in food packaging are related to preservation rather than nutrition, and artificial substances introduced during food processing may not offer the necessary health benefits that natural nutrients provide. Thus, the primary function of nutrients is to support health and well-being, making the first choice the most accurate definition.
