Question

An experimental protocol requires that a nutrient deficiency be induced to assess its effects on memory. What is the most appropriate study design to use to address this question?

Answer 1

The most appropriate study design to use to address this question would be of randomized controlled trial.

Explanation:

• With an intention to induce a kind of deficiency, an individual can be fed with only the food that lacks the particular nutrient whose deficiency is to be created.
• After considerably enough of deprivation of that particular nutrient, the individual can be made to go through a memory test to check whether there is any apparent effect or not.
