BEE: Basal Energy ExpenditureUsing the Mifflin St. Joer Equation • Basal Energy Expenditure (BEE), basal metabolic rate (BMR), and the closely related resting metabolic rate (RMR), is the rate of energy expenditure by humans at rest. • The Mifflin St. Joer Equation BMR (female)=(10 x wt) + (6.25 x ht) – (5 x age) – 161 BMR (male)=(10 x wt) + (6.25 x ht) – (5 x age) – 5 (Note: Wt is expressed in kg and ht in cm) • Example - 42 yr old female, 150 lbs, 5’7” tall Convert: 150 lbs 2.2 kg/lb = 68.18 kg Convert: 67 in x 2.54 cm/in = 170.18 cm BMR = (10 x 68.18 kg) + (6.25 x 170.18 cm) – (5 x 42 yrs) – 161 BMR = 681.8 + 1063.62 – 210 BMR = 1535.42 Realizing Postsecondary and Career Readiness Through CTE
TEF: Thermic Effect of Food Thermic Effect of Food – energy needed to stimulate metabolism, digest food, absorb and transport nutrients to the cells Realizing Postsecondary and Career Readiness Through CTE
EER: Estimated Energy RequirementsTEE: Total Energy Expenditure • BMR is multiplied by an activity factor added to the thermic effect of food to determine the estimated energy requirements (EER) or total energy expenditure (TEE). • Example - Take our 42 yr old female, 150 lbs, 5’7” tall with BMR = 1535.42 Walks 30 minutes/day = low active, PAL factor = 1.4 TEE = (BMR x 1.4) + (BMR x TEF) TEE = (1535.42 x 1.4) + (1535.42 x 0.05) = 22263.35 kcals Realizing Postsecondary and Career Readiness Through CTE
METs: Metabolic Equivalents • One metabolic equivalent (MET) is defined as the amount of oxygen consumed while sitting quietly in a chair, approximately 3.5 ml 02/kg/min (1.2 kcal/min for a 70-kg person). • Work at 2 METS requires 2X the resting metabolism or 7.0 ml O2/kg/min and 3 METS requires 3X the resting metabolism (10.5 ml 02/kg/min), and so on. • The MET concept represents a simple, practical, and easily understood procedure for expressing the energy cost of physical activities as a multiple of the resting metabolic rate. Realizing Postsecondary and Career Readiness Through CTE
METs: Metabolic Equivalents METS for Walking at Various Speeds and Surface Grades • Example- Take our 42 yr old female, 150 lbs, 5’7” tall with BMR = 1535.42 • How many calories would she burn if she walks on a 2.5% grade, 3.75 mph for 30 minutes? • {BMR (24 hr x 60 min/hr)} x METs x min of activity = kcals expended • {1535.42 (1440.00)} x 5.2 METs x 30 min = kcals expended • 1.06 kcals/min x 5.2 METs x 30 min = kcals expended • 165.36 kcals expended during activity Realizing Postsecondary and Career Readiness Through CTE
Calculating Calorie Needs for Burn Patients Rule of Nines • Used to calculate % of body surface area (BSA) burned • Add up percentages of each surface burned and use Curreri formula to calculate calorie needs for healing. • Example – Adult burned on: • Front torso – 18% • Front left arm – 4.5% • Both upper front thighs – 9% (whole leg is 9%; front of each leg is 9% so top half of one leg is 4.5%) • 18 + 4.5 + 9 = 31.5% BSA Realizing Postsecondary and Career Readiness Through CTE
Calculating Calorie Needs for Burn Patients Curreri Formula • Adults: 25 kcal / kg + 40 kcal % BSA burned • Children: 60 kcal/kg + 35 kcal % BSA burned • Example – 175 lb adult burned over 31.5% of BSA • Convert lb to kg: 175 2.2 kg/lb = 79.54 kg • Plug into Curreri Formula: (25 kcal x 79.54 kg) + (40 x 31.5% BSA) 1988.5 + 1260.0 = 3248.5 kcal needed for healing Realizing Postsecondary and Career Readiness Through CTE
Person-centered Health Care Plan • The Health Care Team plays an important role in developing and maintaining a person-centered health care plan. • The team is made up of health care members as well as the patient, family members and support system. Nutrition Care Process • “A systematic problem-solving method that dietetics professionals use to critically think and make decisions to address nutrition-related problems and provides safe and effective quality nutrition care.” - The Academy of Nutrition and Dietetics STEP 1: Nutrition Assessment STEP 2: Nutrition Diagnosis STEP 3: Nutrition Intervention STEP 4: Nutrition Monitoring and Evaluation Realizing Postsecondary and Career Readiness Through CTE
Nutrition Assessment Information about a patient’s situation must be collected from the patient, family members, the medical chart, oral and written communication with staff and others, etc. • Family history • Medical history • Patient’s nutrition status • Patient’s food habits and living situation • Patient’s needs, desires and goals • ABCD approach to nutrition assessment Realizing Postsecondary and Career Readiness Through CTE
ABCDs of Nutrition Assessment Anthropometric Data – measurements of an individual • Age • Gender • Height – expressed in cm • Weight – expressed in kg • Body frame size • Body composition • Body mass index Realizing Postsecondary and Career Readiness Through CTE
Nutrition Assessment: AnthropometricsA Math-integrated Activity • Height – convert to cm • Conversion of in to cm • Height (in) X 2.54 cm/in = Height (cm) • Example: 5’9” = 69 in 69 in X 2.54 = 175.26 cm • Alternative measures for non-ambulatory patients • Measure arm span, fingertip to fingertip for estimated height • Measure knee height from floor and calculate estimated height with formulas below: Female: [(1.8333 X KH) – (0.24 X Age)] + 84.88 Male: [(2.02 X KH) – (0.04 X Age)] + 64.19 • Example: 45 yr old female, KH = 21 in [(1.8333 X 53.34 cm) – (0.24 X 52 yrs)] + 84.88 = Height (cm) 97.78 – 12.48 + 84.88 = 170.18 cm 170.18 cm 2.54 cm/in = 67 in or 5’7” Height Realizing Postsecondary and Career Readiness Through CTE
Nutrition Assessment: AnthropometricsA Math-integrated Activity • Weight – convert to kg • Conversion of lbs to kg: Weight (lbs) 2.2 kg/lb = Weight (kg) Example: 175 lbs 2.2 kg/lb = 79.54 kg • Calculate Body Frame Size • Ht (cm) wrist circumference (cm) = ht/wrist ratio • Example: 5’8” female, wrist circumference = 7” • 68 in x 2.54 cm/in = 172.72 cm • 7 in x 2.54 cm/in = 17.78 cm • 172.72 cm ht 17.78 cm wrist = 9.71 ratio = LARGE FRAME Realizing Postsecondary and Career Readiness Through CTE

Nutrition and Cancer: Risk • 10 million people develop cancer each year. • 7 million die as a result of cancer each year. • 12% of all deaths are due to cancer. • 50% of all cancers and 30-35% of cancer deaths are related to poor diet and excessive alcohol use. • Obesity ↑ risk of colon, kidney, pancreatic, esophageal, and post-menopausal breast cancer. • Weight gain in adulthood is the strongest predictor of breast cancer risk. (National Cancer Institute) • Obese women are 2-4X more likely to develop uterine cancer than normal weight women. • Abdominal fat seems to play a significant role in colon cancer risk. Realizing Postsecondary and Career Readiness Through CTE
Nutrition and Cancer: Prevention • Red meat intake and processed meats significantly ↑ risk of colorectal cancer. • Processed meats and salt-preserved foods ↑ risk of stomach cancer because of carcinogens (nitrates and nitrosamines) in the meats. • Cooking meats at high temperatures (frying, grilling, barbequing) create carcinogenic compounds in the meat (heterocyclic amines) and ↑ risk of colorectal, pancreatic, and breast cancer . • Medium-well and well-done meats triples risk of stomach cancer. • ↑ intake of whole grains and fiber reduces risk of cancer by 1/3. • Diets ↑ in animal fat ↑ risk of colorectal and prostate cancer. • Omega-3 fatty acids are beneficial while omega-6 fatty acids are harmful and promote cancer cell growth, esp. in prostate cancer. Realizing Postsecondary and Career Readiness Through CTE
Nutrition and Cancer: Prevention • Phytochemicals play important role in preventing tumor growth. • The role of soy intake in helping protect against breast cancer and prostate cancer is controversial. More studies are necessary. • Berries top of the list of potential cancer-fighting foods. • High intake of fruits and vegetables, esp. cruciferous vegetables may reduce cancer risk. (broccoli, cabbage, collards, cauliflower, etc.) • Tomatoes may decrease prostate cancer due to the lycopene content. • Regular physical activity↓ obesity and subsequent risk of certain cancers. Realizing Postsecondary and Career Readiness Through CTE
Nutrition and Cancer: Prevention • Beta-carotene may not be as beneficial as once thought, actually increasing cancer risk in smokers. • Garlic and other vegetables in the Allium family (onions, scallions, leeks, chives) show promising effects on cancer prevention. • Vitamin D has shown protective effects against cancer, esp. breast, ovarian, prostate, and colon. • Selenium has been shown to ward off breast , esophageal, stomach, prostate, liver, and bladder cancers. • Alcohol consumption increases risk of cancer of the mouth, throat, larynx, esophagus, breast, and liver. Oral cancer is 6X greater than non-alcohol users. Realizing Postsecondary and Career Readiness Through CTE
