Ch.9 Nutrition Flashcards
Nutrition
A process of obtaining nutrients through food and/or food products to support energy requirements and cellular processes, including growth, repair and maintenance of tissues, reproduction, digestive processes, and respiration.
Registered Dietitian/
Registered
Dietitian
Nutritionist (RD/RDN)
Nationally recognized and credentialed in nutrition by the Commission on Dietetic Registration. Scope of practice ranges from clinical nutrition to community, food service, and nutrition education. Some RDs are board certified in Sports Dietetics (CSSD) for advanced credentialing and specialization in sports nutrition. Although nationally recognized, some states may still require RDs to obtain state licensure prior to practicing independently or in a clinical or medical setting.
Certified Nutritionist
It is important to determine which organization is providing the certification in nutrition and if the organization is accredited. The accredited organizations are officially recognized and authorized to provide a qualification, because they have been reviewed by other governing bodies and found to meet or exceed the minimum standards for education.
CISSN
Certified in Sports Nutrition by the International Society of Sports Nutrition.
CNS
Certified Nutrition Specialist by the Board for Certification of Nutrition Specialists
CDN or LDN
State Certified Dietitian/Nutritionist or Licensed Dietitian/Nutritionist. This is a license to practice nutrition in the certifying/licensing state. This licensure may be legally required in some states, for both RDs and non-RDs, prior to providing any nutrition counseling.
CDN
Certified Dietitian Nutritionist: state certified dietitian/nutritionist
Scope of practice
The actions that a professional is permitted to undertake in keeping with the terms of their license or certification.
Nutrition claim
Claim that a food has a specific nutritional property or provides a specific benefit.
Macronutrients
Food substances required in large amounts to supply energy; include protein, carbohydrate, and fat.
Macronutrients
Food substances required in large amounts to supply energy; include protein, carbohydrate, and fat
Micronutrients
Vitamins, minerals, and phytonutrients. These are nonenergy yielding nutrients that have important regulatory functions in metabolic pathways.
Vitamins
Group of organic compounds required in small quantities in the diet to support growth and metabolic processes.
Minerals
Inorganic, natural substances, some of which are essential in human nutrition. There are two kinds of minerals: major minerals (aka, macrominerals) and trace minerals.
TRUE of FALSE? The scope of practice for a fitness professional dictates that they can prescribe specific meal plans to clients.
False
What is the official term for a statementthat maintains that a food has a specific nutritional property or provides a specific benefit?
Nutrition claim
There are how many amino acids and how are they broken down?
9 essential amino acids not made in body
11 nonessential amino acids made in body
Protein
Amino acids linked by peptide bonds; the building blocks of body tissues.
Amino acids
Organic building blocks of proteins containing both a carboxyl and an amino group.
Peptide bond
A chemical bond that connects two amino acids.
Essential amino acid (EAA)
Amino acid that must be obtained through the diet as the body does not make it; there are nine essential amino acids.
Substrates
Intermediate forms of nutrients used in metabolic reactions to create adenosine triphosphate.
Protein turnover
A process in which the body breaks down existing proteins and recycles the component amino acids for incorporation into new proteins or other nitrogen-containing compounds.

Omnivorous diet
A diet that consists of both animals and plants.
Mutual supplementation
Combination of two incomplete protein sources that together provide all of the essential amino acids.
Protein quality
Refers to the amino acid profile and the digestibility of a protein source.
Low biological value (LBV) proteins
Foods missing one or more of the essential amino acids
High biological value (HBV) proteins
Foods containing all the essential amino acids.
Protein efficiency ratio (PER)
A measure of assessing proteins, based on the amount of weight gained by a test subject divided by the amount of intake of a protein food.
Biological value (BV)
A reference amount used to describe the extent to which the amino acids in a protein source are absorbed.
Protein digestibility– corrected amino acid score (PDCAAS)
A measure for evaluating a protein source based on the composition of amino acids and its digestibility
Net protein utilization (NPU)
The ratio of amino acid mass turned into proteins compared to the total amino acid mass consumed in the diet.
Enterocyte
Intestinal cells that absorb nutrients.
Gluconeogenesis
The formation of glucose from noncarbohydrate sources (proteins and fats).
Recommended dietary allowance (RDA)
The recommended amount of a nutrient that meets the needs of most healthy individuals within specific age and gender groups.
Negative energy balance
When calorie intake is lower than the number of calories expended
Acceptable macronutrient distribution range (AMDR)
Ranges of intake for nutrients that are estimated to meet the needs of 97–98% of the population and that are associated with a reduced risk of chronic disease. AMDRs are established by the National Academy of Medicine.
