Chapter 14: Nutrition Foundations Flashcards
Macronutrients
A type of food necessary in large quantities in the diet to support function and energy production, i.e. carbohydrate, protein, and fat.
Micronutrients
Substances required in small quantities in the diet for optimal body functioning; vitamins and minerals.
Antioxidants
Substances that protect the body from free radicals and the cellular damage they cause.
Catabolism
The breaking down in the body of complex molecules into more simple molecules.
Anabolism
The building of complex molecules in the body from more simple, smaller molecules.
Amino Acids
Simple organic compounds known as the building blocks of proteins.
Glucose
A simple sugar the body uses for energy production on the cellular level.
Glycogen
The stored form of glucose found in the liver and muscles.
Monosaccharides
Any of the class of sugars that cannot be hydrolyzed to give a simple sugar.
Disaccharides
Any of a class of sugars with molecules that contain two monosaccharide residues.
Processed Foods
Foods that have been frozen, packaged, enhanced with vitamins or minerals (fortified), previously cooked, or canned to preserve them for consumption.
Glycemic Index
A system that ranks foods on a scale from 1 to 100 based on their effect on blood sugar levels.
Low GI score
1 to 55
Medium GI score
56 to 69
High GI score
70 and higher
Insulin
A hormone produced in the pancreas to regulate blood sugar.
Hypoglycemia
The condition of lower-than-normal blood glucose.
Obesity
An abnormal or excessive accumulation of body fat that may cause additional health risks.
Dibetes
A condition characterized by an elevated level of glucose in the blood.
US Department of Agriculture
A US federal department that manages programs for food, nutrition, agriculture, natural resources, and rural development.
Vitamins
Organic compounds essential for normal growth and nutrition.
Minerals
Elements in food that the body needs to develop and function.
Unprocessed Foods
Fresh or raw foods that are the natural, edible parts of an animal or plant.
Fiber
A type of carbohydrate derived from plant-based foods that the body is unable to break down.
Soluble Fiber
Soluble fiber dissolves in water and absorbs water from partially digested food.
Low-Density Lipoprotein
The form of lipoprotein in which cholesterol is transported in the blood. It is sometimes considered the “bad cholesterol.”
Insoluble Fiber
Insoluble fiber does not dissolve in water and instead adds bulk to the stool.
Prebiotics
Prebiotics are fibers that are fermented in the gut. Bacteria necessary for digestion use prebiotics as food.
Fats
Organic compounds that are made up of carbon, hydrogen, and oxygen. Fats are a source of energy in foods and are also called lipids. They come in liquid or solid form.
Hydrocarbons
A compound of hydrogen, and carbon, such as any of those that are the chief components of petroleum and natural gas.
Fatty Acids
The smaller, absorbable building blocks of the fat that is found in the body.
Triglyceride
The main component of adipose tissue made of three fatty acids and a glycerol molecule.
Saturated Fats
Saturated fats are usually solid at room temperature and have no double bonds within the molecular structure.
Unsaturated Fats
Unsaturated fats are considered to be a beneficial fat and are usually liquid at room temperature.
Polyunsaturated Fats
Polyunsaturated fats have more than one double bond.
High-Density Lipoprotein
A lipoprotein that removes cholesterol from the blood. It is sometimes considered the “good cholesterol.”
Trans Fat
Trans fats are a type of unsaturated fat. Known as another detrimental fat, trans fats are both naturally occurring and man-made.
Coronary Artery Disease
The narrowing or blockage of coronary arteries.
Essential Fatty Acids
Essential fatty acids cannot be synthesized by the human body, which means they must be obtained from the diet.
Omega 6 Fatty Acid
A family of pro-inflammatory and anti-inflammatory polyunsaturated fatty acids that have in common a final carbon-carbon double bond.
Omega 3 Fatty Acid
An unsaturated fatty acid occurring chiefly in fish oils.
Eicosapentaenoic ACID
A fatty acid found in fish and fish oils, which is believed to lower cholesterol, especially cholesterol bound to low-density lipoproteins.
Docosahexaenoic Acid
An omega-3 fatty acid that is a primary structural component of the human brain, cerebral cortex, skin, sperm, testicles, and retina.
American Heart Association
A nonprofit organization that funds cardiovascular research and educates consumers on healthy living and good cardiac care.
Recommended Daily Allowance
The average daily level of intake that is sufficient to meet the nutrient requirements of nearly all (97%-98%) healthy people.
Linoleum Acid RDA
17 grams per day for men ages 19–50; 12 grams per day for women ages 19–50
Alpha-linolenic Acid RDA
1.6 grams per day for men ages 19–50; 1.1 grams per day for women ages 19–50
Amino Acids
Amino acids are the building blocks of protein.
Essential Amino Acids
Amino acids that are not made by the body in the optimal amounts and therefore must be obtained through the diet.
