fruit, baked chips, oatmeal raisin cookies
epidemiological study - correct answer ✔✔observing relationships between diet, health, and
disease patterns in dif populations
balance study - correct answer ✔✔compares the total amount of a nutrient that enters the
body with the total amount that leaves the body
depletion-repletion study - correct answer ✔✔A study that feeds subjects a diet devoid of a
nutrient until signs of deficiency appear, and then adds the nutrient back to the diet to a level at
which symptoms disappear and health is restored
double blind study - correct answer ✔✔An experiment in which neither the participant nor the
researcher knows whether the participant has received the treatment or the placebo
single blind study - correct answer ✔✔study in which the subjects do not know if they are in the
experimental or the control group
