  1. Stressors that Affect Nutrition NUR101 FALL 2010 LECTURE # 24 K. BURGER, MSED, MSN, RN, CNE PPP By Sharon Niggemeier RN MSN

  2. Nutrition • Nutrition is interaction between an organism and the food it consumes • Food & eating is a basic need, affects health • Various factors affect nutrition • Nutrients – substances used by the body for growth & development • Role of nurse to teach, guide and inform on the importance of proper nutrition

  3. Nutritional health-care Team • MD • Nurse • Social Worker • Physical Therapist • Occupational Therapist • Speech Pathologist • Pharmacist

  4. Water Carbohydrates Proteins Lipids Vitamins Minerals Essential Nutrients Regulatory Nutrients

  5. Water • Water: present in every cell • Absorbed in small /large intestine • Metabolized carbohydrates, proteins, lipids produce water • Dietary intake from fluids and solid food provide water • Function: fluid medium needed for all chemical reactions in the body

  6. Carbohydrates • Carbohydrates: simple or complex • Digested by enzymes (amylase/lactase) • Absorbed in small intestine • Metabolized into glucose which is used for energy or stored…Stored as either glycogen or fat • Function: provide energy, spare proteins

  7. Carbohydrates (CHO) • Carbon – Hydrogen-Oxygen • 1 gram carbohydrate = 4 Kcal • Monosaccharides – simple sugars glucose, fructose, galactose • Dissaccharides – double sugars sucrose, lactose, maltose • Polysaccharides – complex forms starch, glycogen, cellulose (fiber) • Recommended intake: 60% of total Kcal (300g) Fiber 25-30g daily

  8. Carbohydrates • What are some other functions of carbohydrates in our bodies? DIETARY FIBER - Helps regulate blood sugar May reduce risk of hyperlipidemia May reduce risk of some cancers Laxative effects of: LactoseCellulose

  9. Protein • Proteins: composed of amino acids • Digested by enzymes (proteolytic) • Absorbed in small intestine • Metabolism includes: • Anabolism=Catabolism: Nitrogen balance • Function: maintain body tissue and tissue growth

  10. Protein (CHON) • Carbon-Hydrogen-Oxygen- Nitrogen • 1 gram of protein = 4 Kcal • Comprised of 22 amino acids which can be comined by body to form over 1000 types of proteins • 9 essential amino acids – body cannot synthesize them • Complete protein = one with all 9 essential amino acids (animal sources and soy) • Incomplete proteins = contain some but not all essential (plant sources) • Complementary proteins = 2 proteins that when combined provide all essential amino acids. • Recommended intake: 10% total Kcal ( 0.8g per 2.2lbs)

  11. Proteins (CHON) • What are some other functions of proteins? Fluid Balance Ex: Albumin Energy ( last resort)De-amination / Nitrogen stripped from CHON to create glucose CHO

  12. Lipids • Lipids: insoluble in water • Digested by enzymes (lipase,bile) in stomach and small intestine • Absorbed in small intestine • Metabolism includes conversion (by liver and small intestine) into soluble compounds called lipoproteins • Function: energy, insulates body, absorption (fat-soluble vitamins)

  13. Lipids (Fats) • Carbon-Hydrogen-Oxygen • 1 gram of Fat = 9 Kcal • Composed of fatty acids: (linoleic&linolenic =essential) • Saturated fat = mostly animal source • Unsaturated fat = mostly plant and fish sources • Triglyceride = fat in bloodstream /storage form of fat in body. • Trans Fat = hydrogenated fats in processed foods • Recommended intake: 20-35% of total Kcal

  14. Lipids • Lipoproteins - made by the body to move water-insoluble lipids (such as cholesterol) thru the bloodstream • LDL (low density lipoprotein)- major carrier of cholesterol. Function is to transport cholesterol from liver into circulation. “Bad cholesterol” • HDL (High density lipoprotein) - carries cholesterol away from tissue to liver ..high levels decrease atherosclerosis. “Good cholesterol” • Cholesterol- not essential from diet as the body produces enough.

  15. Desirable Blood Lipid Levels • Total Cholesterol < 200 • Triglycerides < 150 • LDL < 100 • HDL > 40 Male > 50 Female • Elevated Blood Lipid Levels(Hyperlipidemia) = increased risk for CHD, Hypertension, Stroke, MI

  16. Vitamins • Vitamins: required in small amounts • water- soluble: absorbed through intestine directly into blood stream (C, B complex folic acid) • fat-soluble: absorbed with lipids into lymphatic circulation (A,D,E,K) • Function: needed for metabolism of carbohydrates, lipids & proteins

  17. Water-soluble vitamins text review Vitamin C (ascorbic acid) • Function: collagen formation (wound healing), antioxidant, immune system • More prone to deficiency; not stored • Deficiency: bleeding gums, scurvy, poor wound healing • Source: citrus fruits, tomatoes, broccoli

  18. Vitamin B Complex : thiamine, riboflavin, niacin, B6, B12 • Function: metabolism of carbs, lipids and proteins • RNA, DNA synthesis (folic acid) & heme formation (B12) • Deficiency:beriberi, poor wound healing, anemia, pernicious anemia • Sources: Whole grains Organ meats

  19. Vitamin B12 (continued) Vitamin B12 (cobalamine) • Important for hemoglobin synthesis • Very little found in vegetable sources (unlike other B Vitamins) • Pernicious anemia = B12 deficiency or lack of intrinsic factor for B12 absorption.Susceptible population = Total VeganClients w/ decreased gastric acid secretion(gastric bypass, stomach cancer) • Rx = B12 injections

  20. Folic Acid Folic Acid (Folate) • Folic Acid Deficiency leads to elevated Homocysteine levels which are associated with increased risk for CHD. • Folic Acid Deficiency linked to neural tube defects – Spina Bifida • Natural folate (in foods) only ½ as available to body as supplement folic acid • 1998 = mandatory fortification of breads/grains • Supplements recommended for: women of child-bearing age, gastric surgery, malabsorption (alcholic)

  21. Fat-soluble Vitamins text review • Vitamin A: function- visual acuity, skin maintenance…deficiency-night blindnessDark green leafy vegs, yellow/orange vegs • Vitamin D: function-calcium absorption… deficiency-rickets, bone malformationFortified milk, ultraviolet light • Vitamin E: function-antioxidant, heme synthesis…deficiency-RBC hemolysis Whole grains, nuts • Vitamin K: function-formation blood clotting proteins…deficiency- hemorrhage Dark green leafy vegs, synthesized by bacteria in sm intestine • More prone to toxicity; stored by body

  22. Minerals • Minerals: macrominerals or microminerals • Originate in earth’s crust, aren’t digested or metabolized. Combine to form salts or organic compounds. Always retain their chemical properties. • Function: provide structure within the body (bones/teeth, F/E and acid /base balance, nerve transmission, muscle contraction)

  23. Macrominerals text review • Calcium: bone/ teeth formation, blood clotting, nerve transmission…deficiency-tetany, osteoporosis • Phosphorous: bones, acid-base balance…deficiency- muscle weakness • Magnesium: bones, metabolism ...deficiency-muscle pain, poor cardiac function • Potassium: f/e balance, acid-base balance… deficiency-muscle cramps , irregular ht. rate

  24. Microminerals text review • Iron: hemoglobin formation…deficiency-anemia • Iodine: thyroid hormones…deficiency- goiter • Zinc: wound healing … deficiency-impaired immune system • Fluoride: teeth/bones…deficiency- discolored tooth enamel

  25. Energy Balance • Kilocalorie- unit of heat; measures the energy in the diet • Basal metabolic rate (BMR)- amount of energy needed for all the biochemical processes to occur when the body is at rest. • Proper nutrition provides the energy needed to maintain health

  26. Ideal body weight IBW = balance of energy used by the body and intake of nutrients Rule of thumbWomen: 100 lbs lst 5ft 5 lbs/inch over 5ftMen: 106 lbs lst 5 ft 6 lbs/inch over 5ft Standardized chartsOverweight = 10% > chartObese = 20% > chart Body mass index(BMI)18.5 – 24.9 healthy> 25 = overweight> 30 = obese> 40 = morbidly obese Body Weight Standards

  27. Factors Affecting Nutrition • Developmental • Gender • Ethnicity & culture • Food beliefs • Preference • Religion

  28. Factors Affecting Nutrition • Lifestyle • Medications & therapy • Heath status • Advertising • Alcohol Consumption • Psychological factors

  29. Adequate Nutrition • Food Guide Pyramid • Daily reference intake • Food Labeling • Dietary guidelines

  30. Food Guide Pyramidmypyramid.gov Bread/Cereal/Rice/Pasta 6 servings Vegetables 3-5 servings Fruits 2-4 servings Milk, Cheese 2-3 servings Meat, Fish, Poultry, Nuts 2-3 servings Fats/Oils/Sweets sparingly

  31. Dietary Guidelines • Balance / Moderation / Variety • Maintain healthy weight • Exercise • Eat a variety of foods in moderation • Low sodium / Low fat / Low simple sugars • Alcohol in moderation

  32. Nursing history Physical exam 24-hr. recall Food records Anthropometic data Lab tests – Albumin & Prealbumin Hemoglobin Transferrin Assessing: Nutrition

  33. Nursing Dx • Imbalanced nutrition: less than body requirements R/T NPO status AEB height 5’6’’ wt 105 lbs., pt. states “ I’ve never been this skinny before, my clothes are hanging off of me” • Impaired dentition R/T nutritional deficits AEB dentures not fitting properly

  34. Planning- outcome criteria • Pt. will: • Attain and maintain ideal body weight • Eat a variety of foods at each meal • Promote healthy nutritional practices

  35. Monitoring food intake Assist with feeding Stimulate appetite Teaching Interventions

  36. NPO Clear liquids-see through (broth, apple juice) Full liquids –foods that turn to liquid at room temp. (shakes, milk) Soft –easily chewed and digested Low residue- no seeds, raw vegetables or fruits, whole grains High fiber- raw fruits, grains, vegetables Sodium restricted: Mild 2 gram Na/day Moderate 1gram Strict 500mg Severe 250 mg DASH Dietary Approaches to Stop Hypertension Diet Restrictions

  37. Calorie restrictions Diabetic diet Cholesterol Food textures:Thick it Thin Nectar-like Honey-like Spoon-thick Diet Restrictions

  38. Enteral Nutrition • Used when oral intake is inadequate, swallowing difficulty, coma • Tube passed into gastrointestinal tract to deliver nutrients • Maintains GI integrity preferred over parental feedings (via veins)

  39. Short term use Nasogastric Nasointestinal Long term use Gastrostomy Percutaneous endoscopic gastrostromy (PEG) Enteral Nutrition

  40. Enteral Formulas • Many types of formulas • Administered continuous or intermittent • Use pumps to monitor intake • Monitor Intake & Output

  41. Enteral Precautions • Prevent aspiration • Position fowlers/high fowlers • Assess placement…check pH • Note residual • Auscultate bowel sounds

  42. Enteral Precautions • Preventing complications include: • Clogged tube • Nasal erosion • Diarrhea • Infection • Dislodgement

  43. Parental Nutrition • Bypasses GI tract, nutrition administered IV, more complicated • Total parental nutrition (TPN) also called (hyperalimentation)…central line • Partial parental nutrition (PPN)..PICC line

  44. Summary • Nurses role, to understand nutrients and how they affect nutrition • Various factors affect one’s nutritional status • Interventions include numerous diets, assisting with feeding, monitoring and teaching • Nutrition can also be administered enterally or parentally
