Domain I: Principles of Dietetics
Epinephrine
- adrenal medulla, stimulates sympathetic nervous system - stimulates liver and muscle glycogenolysis (glycogen -> glucose) - decrease release of insulin from pancreas DURING CATABOLIC STRESS; BS RISES
What is gelatin do?
- changes liquid into elastic solid - acts as a foaming agent in marshmallows - keeps sugar and ice crystals small in candy and ice cream by interfering with the union of small crystals to make larger ones
Evaluation of Effectiveness of educational plans
- did it alter patient knowledge, behavior, or attitude? - what is rate of lapse or relapse? - timeliness, appropriateness, accuracy? within budget? - meet specific targeted needs? quality of presentation? - were processes and outcomes documented? - what was the degree of growth?
Sources of glucose
- dietary - liver glycogen - products of intermediate metabolism (reconversion of lactic acid and pyruvic acid)
cobalt: properties
- exists with B12 - stored in liver
Modified food examples
- fermented dairy products (probiotics to support GI health) - fortified margarines (plant sterols and stanol esters which reduce total and LDL cholesterol) - calcium-fortified OJ - iodized dalt - folate enriched breads
To perform gas exchange analysis, the following are measured/calculated:
- fraction of inspired and expired oxygen (FIO2, FEO2) and carbon dioxide (FICO2, FECO2) - inspired and expired minute gas volume (VI, VE) - from these quantities, VO2 and VCO2 can be calculated
Tissue stores of glucose
- glycogen in the liver and muscle - fat from adipose tissue - cellular mass (protein stores) - gluconeogenesis
group process
- relieve social concerns of the group, all must feel accepted - tolerate silence - guide & encourage interactions; do not become focus - know when and how to resume control - reinforce multi-sided nature of communication (how do you feel about that?) - exercise control over talkative participants; encourage silent members - halt side convos - help group stay on topic (avoid showing preference)
Catabolism
- the breakdown of complex molecules in living organisms to form simpler ones, together with the release of energy - creates a constant energy deficit, which must be applied by food *Uses are releases energy
Sources of calcium
-Dairy products -Leafy veggies -Legumes
Stature/length for age
-Defines shortness/ tallness -Reflects long term NTR status -Determines extent of stunting -Affected by long-term nutritional stress or chronic illness < 5th= short stature

What are the functions of carbohydrates?
1) energy 2) protein sparing action (allowing most of protein to be used for tissue synthesis) 3) regulation of fat metabolism- a CHO restriction leads to ketosis
Catabolism steps
1) first step is deamination - splitting off of NH2 by hydrolysis in liver 2) NH2 converted into ammonia (NH3) which is TOXIC 3) most of the ammonia is converted into urea and excreted by the kidney 4) some is converted into purines, and some is used to make the nonessential amino acids through transamination 5) the remaining carbon chain is a ketoacid; it can be oxidized for energy
cultural communication styles differ

Evaluating acid-base abnormalities
1. Check pH. Acidosis is below 7.4 and alkalosis is above 7.4. 2. Look at the cause. pCO2 is the blood gas reading that measures carbonic acid regualred by the lungs; will tell you if the lungs are working normally. HCO3 (checks base) measures base, regulated by the kidneys. This will tell you if the kidneys are functioning well.
Stages of a bill becoming a law
1. Legislation enters a bill or resolution. 2. Bill is sent to committees which schedule public hearings where testimony is taken from bill's sponsors. (Nutritionists can present views here or in earlier planning stages). 3. The committee revises bill during a markup session and put into final form. If it is approved, it is sent to Rules Committee for debate. 4. It needs approval from both houses (House of Reps and Senate) and president. 5. Differences between the 2 houses are worked out in a joint house sentate conference committee (usually passing a reconciliation of a bill). 6. Appropriations bull must be passed to provide funding *** 7. Formulate regulations that interpret and operate the law - federal regulation interprets a law and provides details and rules that put the policy into effect (carries the force of a law but is easier to change) - regulations are written by staff members of the agencies charged with enforcing the regulations
