Introduction to Nutrients & Nutritional
Labeling
Nutrition -
Is the provision, to cells and organisms, of the materials necessary to support life,
nutrients.
Nutrition -
Is the nourishment provided to the body by the diet which is eaten. Is also classified as
proper or poor.
Proper Nutrition -
Provides the body with the nutrients needed for optimal growth, development and
health.
Poor Nutrition -
Lacks the nutrients needed for optimal growth, development and health.
Nutrition of the Human Body -
•Is based on the amount of nutrients consumed through food and beverages, as well as
dietary supplements
•Involved essential factors for normal functioning of the body
•Includes the proper balance of protein, carbohydrates, vitamins, minerals, fats and water.
Nutrients -
•Are compounds found in foods
•Perform specific functions in the human body
•Can be essential or non-essential
•Are broken into six different classes.
Essential Nutrients -
•Cannot be manufactured by the body
•Must be consumed through foods
•Are required for maintenance and functioning of the body.
Non-Essential Nutrients -
•Can be manufactured by the body
•Are also consumed through foods
•Are required for proper maintenance and functioning of the body.
Non-Essential Nutrient -
Vitamin D aids the body in calcium absorption and is an example of a non-essential
nutrient. The body synthesizes the vitamin when exposed to sunlight. However, it is
beneficial to consume foods fortified with vitamin D.

, The Six Essential Nutrient Classes -
Are divided based on the purpose each nutrient serves in the body.
•Carbohydrates
•Fats
•Minerals
•Proteins
•Vitamins
•Water -
What are the six essential nutrient classes?
Calories -
Carbohydrates, fats, and proteins al contain this, however vitamins, minerals, and water
do not contain this.
Proteins -
•Is the main building block of ever cell in the human body
•Performs three functions in the body:
1. Grows and repairs damaged tissues
2. Regulates body functions
3. Provides energy
Proteins -
•Are composed of 20 different amino acids
•Enable the body to form muscle fibers and form enzymes
Proteins -
•Contain nitrogen, slowing for the synthesis of non-essential amino acids
•Are commonly recognized for building and repairing cells
Enzymes -
•Are made of proteins
•Utilize a variety of combinations of the 20 amino acids
•Enable essential body processes by allowing cells to perform necessary chemical reactions
Amino Acids -
•Are composed varying chains of hydrogen, nitrogen, carbon, and oxygen molecules
•Can be though of as building blocks for protein
•Classify proteins as complete or incomplete, based on the types of amino acids contained in
the protein
Essential Amino Acids -
•Cannot be synthesized by the body and must be consumed through food
•Are not stored by the body and must be consumed daily
•Include nine for healthy adults and ten for children
Ten Essential Amino Acids -
Children and infants require these as the body does not produce sufficient amounts of
arginine until later in life.
