Q

how does prospective dietary evaluation help mitigate recall bias and provide a more accurate estimation

A
  • Requires greater patient compliance and later-date follow-up
  • Longer log period = greater accuracy

role of iodine
majority is incorporated into thyroid hormones for metabolic function
61
risk for deficiency of iodine
Countries with low iodine content in soil and no required fortification
62
s/s of deficiency of iodine
- thyroid goiter - In pregnant women - pregnancy loss, infant psychomotor retardation, cretinism
63
what are the 2 bone minerals and what are their differences
1. calcium - fortified foods - s/s of deficiency: neuro/MSK symptoms (weakness, AMS, muscle spasm, muscle weakness, thinned bones) - Risk factors: restricted diet, malabsorption/GI disease 2. magnesium - s/s of deficiency - neuro/MSK symptoms (fatigue, weakness, AMS, muscle spasm, muscle weakness) - Risk factors: + renal disease, diuretics, PPIs
64
9 out of 20 dietary amino acids cannot be synthesized and must be consumed
