The study of nutrition does not typically involve which one of these activities?

As there is no options given, but the right answer for this question is "determining if compounds used in food packaging enter foods".

Nutrition refers to the study and investigation of supplements and nutrients that are present in the food , how the body utilizes these nutrients and supplements, and the connection between diet, health, and disease. Significant food manufacturers employ nutritionists and food scientists.

From these choices:
a. determining how food pricing affects food purchases
b. determining how a nutrient is broken down and excreted from the body
c. determining how diet affects the risk of disease
d. determining if compounds used in food packaging enter foods
The answer is letter A. This is because it is does not need to know the procurement of the food purchases. If you study nutrition, you should only study all about the food, not the price.
