Proteins, carbohydrates, vitamins, minerals, amino acids, and enzymes are the basic elements our bodies use to create and maintain life A specific balance of these elements is required to maintain optimal health

(1) The process of the body using food to sustain life (2) The study of food and diet
In the broadest sense, a process or series of processes by which the living organism as a whole (or its component parts or organs) is maintained in its normal condition of life and growth
A three-part process that gives the body the nutrients it needs First, you eat or drink food Second, the body breaks the food down into nutrients Third, the nutrients travel through the bloodstream to different parts of the body where they are used as "fuel" and for many other purposes To give your body proper nutrition, you have to eat and drink enough of the foods that contain key nutrients
(physiology) the organic process of nourishing or being nourished; the processes by which an organism assimilates food and uses it for growth and maintenance
Nutrition is the process of taking food into the body and absorbing the nutrients in those foods. There are alternative sources of nutrition to animal meat. Processes of taking in and utilizing food substances. Food generates energy and supplies materials used in body tissues and processes. Calories are supplied by carbohydrates (sugars and starches), fats, and proteins. Other nutrients include minerals, vitamins, and dietary fibre. Minerals are used in many ways iron for hemoglobin; calcium for bones, teeth, and cellular processes; sodium and potassium to regulate homeostasis, iodine to produce thyroid hormones. Trace minerals have functions that are less well-understood. Fibre is not broken down chemically in the body but aids digestion, lowers blood cholesterol, and may help prevent some cancers and hypertension. Different amounts of these nutrients exist in different foods; a varied diet ensures an adequate supply. Nutritional supplements, required by some people, do not compensate for an unhealthy diet. Sufficient water is always essential. Inadequate nutrient intake or absorption leads to malnutrition and disease

Getting enough of the right foods with vitamins and minerals a body needs to stay healthy Malnutrition, or the lack of proper nutrition, can be a serious problem for older people
Nutrition is the process of nourishing, by which organisms obtain energy (in the form of food) for growth, maintenance, and repair
All the processes involved in the taking in and utilization of food substances by which growth, repair, and maintenance of activities in the body as a whole or in any of its parts are accomplished Includes ingestion, digestion, absorption, and metabolism
process by which a living organism uses food for health, growth, and replacement of tissues
In a more limited sense, the process by which the living tissues take up, from the blood, matters necessary either for their repair or for the performance of their healthy functions
the scientific study of food and drink (especially in humans) (physiology) the organic process of nourishing or being nourished; the processes by which an organism assimilates food and uses it for growth and maintenance
