Chapter 9: Nutrition Flashcards
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, and digestive processes and respiration
Nutrition
Certified Dietitian Nutritionist: state certified dietitian/nuitritionist
CDN
The actions that a professional is permitted to undertake in keeping with the terms of their license or certification
Scope of practice
Claim that a food has a specific nutritional property or provides a specific benefit
Nutrition Claim
Food substances required in large amounts to supply energy; include protein, carbohydrate, and fat
Macronutrients
Vitamins, minerals, and phytonutrients. These are nonenergy yielding nutrients that have important regulatory functions in metabolic pathways
Micronutrients
Group of organic compounds required in small quantities in the diet to support growth and metabolic processes
Vitamins
Inorganic, natural substances, some of which are essential in human nutrition. There are two kinds of minerals: major minerals (aka, macrominerals) and trace minerals
Minerals
Amino acids linked by peptide bonds; the building blocks of body tissues
Protein
Organic building blocks of proteins containing both a carboxyl and an amino group
Amino acids
A chemical bond that connects two amino acids
Peptide bond
Amino acid that must be obtained through the diet as the body does not make it; there are nine essential amino acids
Essential amino acid (EAA)
Intermediate forms of nutrients used in metabolic reactions to create adenosine triphosphate
Substrates
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
Protein turnover
A protein source that provides all essential amino acids
Complete protein
A protein that lacks one or more of the amino acids required to build cells
Incomplete protein
A diet that consists of both animals and plants
Omnivorous diet
Combination of two incomplete protein sources that together provide all of the essential amino acids
Mutual supplementation
Refers to the amino acid profile and the digestibility of a protein source
Protein quality
Foods missing one or more of the essential amino acids
Low biological value (LBV) proteins
Foods containing all the essential amino acids
High biological value (HBV) proteins
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
Protein efficiency ratio (PER)
A reference amount used to describe the extent to which the amino acids in a protein source are absorbed
Biological value (BV)
A measure for evaluating a protein source based on the composition of amino acids and its digestibility
Protein digestibility- corrected amino acid score (PDCAAS)
The ratio of amino acid mass turned into proteins compared to the total amino acid mass consumed in the diet
Net protein utilization (NPU)
Intestinal cells that absorb nutrients
Enterocyte
The formation of glucose from noncarbohydrate sources (proteins and fats)
Gluconeogenesis
The recommended amount of a nutrient that meets the needs of most healthy individuals within specific age and gender groups
Recommended dietary allowance (RDA)
When calorie intake is lower than the number of calories expended
Negative energy balance
Ranges of intake for nutrients that are estimated to meet the needs of 97-87% of the population and that are associated with a reduced risk of chronic disease. AMDRs are established by the national academy of medicine
Acceptable macronutrient distribution range (AMDR)
Process relating to, involving, or requiring oxygen
Aerobic
Processes relating to the absence of oxygen
Anaerobic
The energy required to digest, absorb, and process nutrients that are consumbed
Thermic effect of food (TEF)
Compounds composed of carbon, hydrogen, and oxygen molecules that include simple sugars, complex carbohydrates, glycogen, and fiber
Carbohydrates
Include the monosaccharides and disaccharides; easily absorbed into the bloodstream
Simple sugars
