What are the 4 types of malnutrition? What causes each type? - ✔✔
-Overnutrition
-Secondary malnutrition
-Micronutrient Malnutrition
-Protein Calorie/Energy Malnutrition
What is the "environmental enteropathy" and that is its' proposed mechanism? - ✔✔a small intestine
disorder triggered by constant ingestion of feces
What is the relationship between toilets and stunning? - ✔✔
-The use of sanitary waste disposal and clean water is important in reducing secondary malnutrition
-prevention of transmission of parasites and diarrheal diseases
-Hookworm acquired by walking barefoot over contaminated soil
-other roundworms infections use oral fecal route
Normal role of carbohydrates, proteins, glucose, and fat - ✔✔Role of carbohydrates: Involuntary use,
physical activity, mental activity, fighting disease, growth
Role of protein: building cells that make up muscle, membranes, cartilage and hair, carrying oxygen,
nutrient transport, antibodies, enzymes needed for most chemical reactions in the body; normally 2-5%
used for energy; broken down to glucose when carbs not avaliable
Glucose: 50-100 gm stored in liver and available to blood and brain. ~350gm stored in and only available
to muscles
Fat: 90% stored energy in the adult; required oxygen for energy production; some carb is needed for
energy production
,Describe the changes in the use of carbohydrate, fat and protein during starvation - ✔✔Negative
nitrogen balance: 12-15g excreted through urine
-skeletal muscle broken down to produce glucose using 75g per day of protein
-about 160gm of body fat also used
-after about a month: 2-4 g nitrogen lost per day, breakdown of skeletal muscle slows (only cells that
have to use glucose)
Gradual shift in metabolic fuels
- 1st: glucose produced from protein breakdown to provide energy
-2nd: fat breakdown and metabolism provedes ketones for all tissues except CNS, Red and white blood
cells
-serum fatty acid levels increase
-serum albumin is normal until late in starvation
Weight loss: first week a lot of salt and water loss
BMR and total energy expenditure decreased in prolonged starvation: decreased activity, increased
sleep, decreased body temperature
What is a problem in both industrialized and developing countries and why? - ✔✔Overnutrition: Because
of the readily avaliable access to fatty, salty, and sugary foods
How does the body adapt metabolically to malnutrition? - ✔✔
What nutrition is required for energy production and where does it come from when not in the diet? -
✔✔
How is nutritional status assessed? What is the result of good nutrition? - ✔✔Clinical Assessments:
physical signs
Anthropometric assessment: Height, Weight, BMI, body composition
Growth: low height for age (stunting), Low weight for height (wasting)
What might happen to the capacity to work with undernutrition? - ✔✔Decreases because of the
excessive exhaustion and decreased BMR
What was the purpose of the Keys' study? - ✔✔To study the effects of extreme starvation on the body
and to help determine the effects of refeeding to help people who had undergone starvation during
WWII
What were the physical symptoms exhibited during the semi starvation in the Keyes study? - ✔✔-Loss of
weight
-Loss of muscle
-Anemia
-Fatigue
-Dizziness
-Edema
-Inability to tolerate
-hot or cold temperatures
-Hair loss
What were the psychological effects of starvation exhibited during the semi starvation in the Keyes
study? - ✔✔-Irritability
-Apathy
-Impatience
