Term | Definition |
Nutrition | The science of food |
Optimal | Enough to support normal functions |
Under nutrition | Does not intake enough to support normal functions (subclinical and clinical deficiencies) |
Over nutrition | More nutrients than the body can support (obesity and toxicities) |
Which nutrients provide energy | Carbohydrates (fruit), proteins, alcohol and lipids |
What are anthropometric measurements | Measuring various aspects of the body (weight and height) |
Chronic disease causes | Diabetes, cancer, osteoporosis, obesity |
Stability of fat and water soluble vitamins in cooking | Fat- high toxic in foods, Water- easily destroyed in cooking |
Excretion of fat and water soluble vitamins | Fat- easily stored in the body, Water- easily excreted in the body |
Name the fat soluble vitamins | Fat- A,D,E,K Water- B,C |
Functions of water | Lubricant, solvent, transportation medium and regulates body temperature |
Calculate calories | Multiply carbohydrates 4, proteins 9 and fat 4 by their physiological fuel value then add them together |
Calorie | The amount of energy in food |
Factors that effect food choices | Hunger versus appetite, flavor, culture, lifestyle, cost, marketing and knowledge |
RDA and its goal | Recommended Dietary Allowances, to prevent deficiency and chronic disease |
Nutrient dense | Assessing the nutritional quality of an individual food |
Calorie reference for daily value | Daily calorie intake |
Dietary guidelines for Americans- why do we have them | Americans are too high in calories, fat, saturated and trans fat, cholesterol, sugar, salt and alcohol. Many don't consume enough of the good stuff. Too much diabetes and obesity |
Agency that regulates food labels | FDA |
What are UL's | Highest number of nutrients you can take in |
Servings required on food labels | Specified by FDA, consistent among other foods |
WIC program | Special supplement program for women, infants and children |
Guidelines for organic foods | Biological pest management, composting, manure application and crop rotations |
Cross contamination | Cutting raw meat and vegetables on the same cutting board |
Temperature danger zone | 41 to 135 degrees Fahrenheit |
Causes of staphylococcus | 1 to 6 hours; diarrhea, vomiting, nausea, cramps |
Causes of salmonella | 12 to 72 hours; nausea, fever, cramps, headache |

Food left out- what are the guidelines | Seal with a tight lid, keep refrigerated or frozen, keep hot foods hot, refrigerate leftovers immediately |
Public water supply | Safe |
Bottles vs tap water safety | Safe but expensive- boil tap water for ultimate safety |
Pyloric sphincter | Controls flow of stomach content into small intestine |
Where most digestion occurs | Small intestine |
Peristalsis | Contractions that push food is mixed with digestive secretions down the GI tract |
Bile function | Fat digestion |
Enzymes | Digest carbs, fat, protein |
Digestion begins | In the mouth and with amylase |
Role of epiglottis | Prevent food from lodging into trachea |
Chyme | Juice from digested food |
Heartburn | Caused by acid reflux |
Pepsin | Digests proteins |
Segments of small intestine | Duodenum, jejunum, ileum |
Treatment for constipation | Fiber, fluid, exercise, and laxative |
Causes of ulcers | H. Pylori, alcohol, aspirin and smoking |
Secretin | Stimulates release of pancreatic bicarbonate |
The 3 monosaccharides | Glucose, Fructose, Galactose |
The 3 disaccharides | Maltose (glucose and glucose) Sucrose ( galactose and glucose) Lactose (glucose and fructose) |
Functions of carbohydrates | Provide energy, protein sparing, and prevents ketosis |
Storage form of glucose | Glycogen |
Glucose is the primary fuel source for the body | True |
Carbohydrates= | 4 Kcal/gram |
Lactose intolerant | Insufficiency of lactose |
Causes of ketosis | Type 1 diabetes, not enough insulin produced |
Pancreas makes insulin | True |
Hypoglycemia | Low blood glucose |
Hyperglycemia | High blood glucose |
Diverticula | Pouches that have extruded through the exterior wall of the large intestine |
Food sources of fiber | Fruits, grains, nuts |
Triglyceride | Major form of lipid in the body and in food |
Functions of fat | Energy, vitamin absorption and insulation |
Essential fatty acids | Aphla- linolenic acid and linolenic acid |

Food sources of saturated fatty acids | Fat, pork, butter, coconut oil |
Food sources of monounsaturated fatty acids | Olive and peanut oil |
Desirable total blood cholesterol level | <200 |
Cholesterol | Waxy lipid found in all body cells |
Good (HDL) | Picks up/recycles/disposes of cholesterol |
Bad (LDL) | Lipoprotein in the blood contains cholesterol |
Risk factors for heart disease | Can change blood triglyceride and cholesterol levels, hypertension, smoking, physical inactivity, obesity, diabetes and other diseases |
Total fat intake recommendation from the American Heart Association | 25%-35%of total calories |
