FSN 210 Midterm Flashcards
Fetal Alcohol Syndrome (FAS)
Range of physical, behavioral & cognitive disorders caused by prenatal alcohol exposure.
Symptoms of FAS
Prenatal & postnatal growth retardation, Impairment of brain & central nervous system, Abnormalities of face, skull, cleft palate, heart, ear, genital, eyes & urinary defects
Amount of alcohol in a drink
Drink is ½ oz of pure ethanol, 12 oz beer (5%), 10 oz wine cooler, 5 oz wine(12%), 1 ½ oz liquor (80 proof whiskey, gin, brandy, rum, vodka) (40%)
Basal Metabolic Rate (BMR)
2/3 of energy expenditure. Supports basic processes of life. Measured when lying still after sleeping & 12-14 hour overnight fast.
Physical Activity
Most variable. Weight loss & weight gain. Duration, frequency & intensity influence energy expenditure.
Thermic Effect of Food (TEF)
10% of total energy intake & involves digestion & absorption.
Increase BMR
Exercise (increase muscle mass), Height (taller = higher BMR), Stress (physical) Growth, fever, premenstrual hormones, smoking ciggs, caffeine.
Decrease BMR
Aging, less PA, sleeping a lot, fasting (strict dieting)
Calculate BMI
wt lbs *703/(ht inches)2
BMI Levels
40 Extreme obese
Health risks of being overweight
Diabetes type 2, heat disease, CHD-coronary heart disease (higher flammatory, LDL ADL TG, Stroke + hypertension = high blood pressure , Injury to bones, sleep apnea, fatty liver, some cancers
Health risks of being underweight
Organ failure, malnourished (decreases immunity-sick) pregnancies – offsprings. Infertility, osteoporosis, medical stress.
Strategies for gaining weight
Fruit juice, healthy high fat foods (nuts, cheese, avocados) cook w/ olive oil, bigger portions, dried fruits
Fat stored
In adipose tissue
How is fat measured?
Skinfold measures, Hydrodensitometry, Bioelectrical impedance, Air displacement plethysmography, Dual energy X-ray absorptiometry
Body fat: Risks of diseases
Heart disease, Stroke, Diabetes, Hypertension, Gallstones, Some cancers
Causes of Obesity
Genetics, SES (socioeconomic status), stress, activity level, portion sizes (behavior), metabolic
Weight loss drugs
Orlistat –(Xenical, Alli) Causes gas, diarrhea, cramping, oily stools, reduced levels of vitamin E & B-carotene Qnexa – (Topomax & Phentermine) Dry mouth, constipation, memory loss, insomnia, birth defects
Bariatric surgery
BMI ≥ 40 or >35 with health conditions, < 1% death rate, 20-30% have surgical complications, Nutritional complications: Fe deficiency, Low B12 & folate levels, Decreased bone density
Fad diets
Claims, see quick results, before/after pics, celebrities, don’t have to make choices. Fad diets – Do they support weight loss & support good health over the long term? NO. What are some of the adverse effects of low CHO diets? Hungry, impair brain function need 130 g carbs/day, decreases energy, ketosis
