Lecture 2: Types of Malnutrition Flashcards
Overnutrition is caused by what?
Leads to what?
Excess calories, lack exercise
leads to obesity, diabetes, hypertension, cardiovascular disease
“Transition diets” considered as cure for what?
Overnutrition
Globally, 90% of all deaths // to chronic disease are already occurring to ______ countries
low to middle income
Overnutrition following fetal malnutrition has also been linked to ___________
chronic disease risk in adulthood
Define secondary malnutrition
not directly caused by the diet
Secondary malnutrition results from what?
From a condition that prevents proper ingestion, digestion or absorption, and metabolism
Often accompanies other types of malnutrition and makes them worse
Which form of malnutrition accompanies other types of malnutrition and makes them worse
Secondary malnutrition
Causative conditions of Secondary Malnutrition
- loss of appetite
- changes in normal metabolism increasing nutritional requirements (during infection/fever), (HIV/AIDS)
- Prevention of nutrition absorption (diarrheal infection causing changes in intestinal absorptive cells)
- Diversion of nutrients to parasitic agents themselves like: Hookworms, tapeworms,
schistosome worms - Malaria –(illness can lead to decrease appetite,
redirection of energy to fighting illness versus focus
on absorption of nutrients, affects immunity). - Anemia, Vitamin A deficiency, and loss of appetite most significant consequences of infestation
- “Environmental enteropathy”
- Small intestinal disorder triggered
by constant ingestion of feces via
contaminated food and water - Results in “leak” of bacteria
through intestinal walls into blood
stream - Results in low-grade infections that
require large amounts of energy to
fight - Leaves fewer nutrients for
growth

Prevention of Secondary Malnutrition/Nutrient Diversion
- Sanitary waste disposal and clean water (prevent parasite transmission/diarrhea, hookworms from barefoot on bad coil, roundworm infection from oral-fecal)
- Washing/cooking veggies (eggs stick to veggies)
- Handwashing/cleanliness
- Using toilets > open defecation
Causation fo Micronutrient Malnutrition
Deficiencies of: VitA, Iodine, Iron, others (Zn, VitD, Vitc, B’s)
Define Protein Calorie Malnutrition aka. “Protein Energy Malnutrition (PEM)”
An extreme lack of protein and kcal.
Rarely have protein deficiency without ______
without calorie deficiency
