Nutrition is the process of using food and water to obtain nutrients that support life.
Nutrition is the biochemical and physiological process by which an organism uses food and water to support life. Through intake, organisms obtain nutrients (both macronutrients and micronutrients) that can be metabolized to generate energy and build chemical structures needed for survival, growth, and reproduction. If an essential nutrient is consumed in too little or too much quantity, malnutrition or nutrient-related health problems can result. The purpose of nutrition is therefore to ensure the body receives the right nutrients for proper metabolic function and maintenance. Nutritional needs vary by organism and by how they obtain nutrients—by consuming organic matter, consuming inorganic matter, absorbing light, or using combinations of these strategies. All life requires carbon, energy, and water, while different organisms (e.g., animals, plants, fungi, and microorganisms) obtain and process nutrients in distinct ways to meet their specific requirements.
Nutrition is the process of using food and water to obtain nutrients that support life.
Nutrients are metabolized to produce energy and form chemical structures; imbalance can cause malnutrition or toxicity.
Different organisms require different nutrients and obtain them through varied strategies such as consuming matter or using light.
The biochemical and physiological process by which an organism uses food and water to support its life.
Primary nutrients required in larger amounts to support major functions in the body.
Nutrients required in trace amounts, including vitamins and minerals.
Health problems that occur when an organism does not get the nutrients it needs, either from deficiency or imbalance.
A nutrient the body cannot synthesize on its own and must obtain from the diet.
The biochemical reactions that use absorbed nutrients to generate energy and build cellular components.
