Function of iron it is responsible for hemoglobin formation/function, cellular oxidation of glucose, antibody production, and collagen synthesis Iron food sources what increased the absorption of iron? lean red meats, organ meat, egg yolks, whole grains, green leafy vegetables, beans, raisins, peanut butter Vit C increases absorption of iron (OJ, tomatoes) What factors influence the body's need for protein tissue growth needs quality of the dietary protein added needs due to illness pregnancy/lactation
What is the difference between complete and incomplete proteins? complete: generally from animals sources and contains all 9 essential amino acids incomplete: generally from plants (grains, nuts, legumes, fruits, vegetables) and do not contain all of the essential amino acids What is B12 and why is it important? What causes a deficiency? water soluble vitamin AKA Cobalamin
- necessary for the production of RBC
- deficiency is causes pernicious anemia and is seen mosly in strict vegetarians and those with the absence of intrinsic factor needed for absorption of b Sources of B food of animal origin: beef liver, shell fish, fortified grains Function of Vitamin C water soluble vitamin aka "ascorbic acid" iron absportion, antioxidant, tissue building
A,D,E,K - have potential for toxicity due to ability to be stored in body for long periods of time -stored in the liver and fatty tissues, and are eliminated much more slowly than water-soluble vitamins A: vision D: bone development E: protects cells from oxidation K: normal blood clotting Water soluble vitamins Vitamin C and B-complex -your body metabolizes what it can and flushes out the excess through pee C: iron absorption, antioxidant, tissue building B: cell metabolism, energy, neurological function (Thiamin, Riboflavin, Niacin, Pantothenic acid, Pyridoxine, Folate, Cobalamin) Vitamin D function: maintain serum calcium and phosphorus, aid in bone development
sources: fish, fortified dairy products, SUNLIGHT deficiency: low serun calcium, fragile bones, rickets B water soluble vitamin aka "thamin" function: muscle energy, GI support, CV support sources: meats, grains, legumes deficiency: Beriberi, altered digestion, CNS and CV problems CHO carbohydrate: organic compounds composed of carbon, hydrogen, and oxygen types: monosaccharides (glucose, fructose, galactose), disaccharides (sucrose, lactose, maltose), polysaccharides (starches, fiber) fuction: to provide ENERGY for the body *130 g/day needed to fuel the brain Low cholesterol diet avoid saturated and trans fats (red meat, full fat dairy)
indications: clients who have chewing or swallowing difficulties, oral or facial surgery, wired jaws soft (Bland, Low-Fiber) diet whole foods that are low in fiber, lightly seasoned, and easily digested -High fiber gas forming foods are excluded (fruits, veggies, beans, coarse breads/cereals) Indications: clints transitioning between full liquid and regular diet, acute infections, chewing difficulties, or GI disorder Mechanical Soft diet modified in texture to include foods that require minimal chewing before swallowing (ground meats, canned fruits, softly cooked vegetables) indications: limited chewing ability; dysphagia, porrly fitting dentures, edentulous (w/out teeth), surgery to head/neck/mouth, strictures of the intestinal tract Lactulose or lactose intolerant
Lactose intolerance occurs when the body is unable to breakdown all of the lactose (predominant sugar in milk) due inadequate lactase (enzyme that digests lactose into glucose and galactose) Lactose is contained in milk and dairy products such as cheese, yogurt, icecream, sherbert symptoms: abdominal distension, flatus, occasional diarrhea nursing concern: substitute calcium with other sources such as tofu, beans, and vegetables; in infants: substitute soy or casein hydrolysate formulas low sodium diet limit sodium to 1500-2000mg/day -benefits patients with cardiovascular risks including heart failure, hypertension, African-American ethnicity, and all middle aged and older adults. high fiber diet promotes normal bowel functioning and is associated with decreased risk factors for certain ancers My Plate diet: consume a minimum of 5 servings of fiber-rich fruits and vegetables and adequate fluid intake
- 25 g/day for women and 38 g/day for men
Add cheese, peanute butter, chopper hard-boiled eggs or yogurt to foods Dips meat in eggs or milk and coat with bread crumbs before cooking Nuts and beans Albumin lab values and significance Indicates if body is absorbing enough protein Prealbumin: 17-40 mg/dL -used to assess critically ill clients who are at a higher risk for malnutition; reflects acute changes Albumin: 3.5-5 mg/dL -chronic measurement What does a complete cholesterol test measure? •Total cholesterol: this is the total amount of cholesterol in your blood. (should be <200 mg/dL) •Low-density lipoprotein (LDL) cholesterol: this is referred to as "bad" cholesterol and too much of it can lead to heart attack, stroke, and atherosclerosis. (should be <150 md/dL)
•High-density lipoprotein (HDL) cholesterol: this is referred to as "good" cholesterol because it helps remove LDL cholesterol from your blood and tranports it to the liver. (should be >60 md/dL) •Triglycerides: when you eat, your body converts the calories it doesn't need into triglycerides, which are stored in your fat cells. People who are overweight or diabetic or who eat too many sweets or drink too much alcohol can have high triglyceride levels. (should be <150 md/dL) Ca+ sreum calcium blood test: 9.0-10.5 mg/dL All cells need calcium in order to work. Calcium helps build strong bones and teeth. It is important for heart function, and helps with muscle contraction, nerve signaling, and blood clotting Deficiency: osteoporosis, tetany, Chvostek's and Trousseau's signs, ECG changes Excess: constipation, kidney stones Hemoglobin (Hgb) females: 12-16 g/dl males: 14-18 g/dl
deficiency: anemia, WBC disorders, recent/long term blood blood excess: dehydration, polycythemia vera, lung/heart disease BMI Body Mass Index normal/healthy weight: 18.5-24. overweight: 25-29. obese: 30+ morbidly ovese: > BMI = weight in lbs/height in inches/height in inches x 703 How many cal/g of energy to carbohydrates provide? Protein? Lipids? Carbohydrates: 4 cal/g Protein: 4 cal/g Lipids 9 cal/g RDA - percentages of major nutrients needed for adults Carbohydrates: 45-65% Protein: 10%

Why is protein so important?
20% protein (essential for rapid tissue growth of maternal and fetal structures, amniotic fluid, and extra blood volume), 30% fat, 50% carbs the need for which vitamins/mineral increase with pregnancy? Protein, Vit A, Vit C, Thiamin, Vit B6, Folate, Vit B12, Iron additional dietary recommendations during pregnancy 2-3 ml of fluids daily <300 mg/day caffeine 600 mcg/day folic acid - for neurological development of fetus and to prevent birth defects; maternal blood cell formation
- consuming foods high in Vit C aids in absorption of iron what is the difference between folate and folic acid? Folate occurs naturally in food, and folic acid is the synthetic form of this vitamin. Sources of folate include liver, grean leafy vegetables, grains, & legumes
