Answer to Question 1

D
Feedback:
Sodium is largely responsible for regulating fluid balance. It also regulates cell permeability and the movement of fluid, electrolytes, glucose, insulin, and amino acids. Sodium is pivotal in acidbase balance, nerve transmission, and muscular irritability.

Answer to Question 2

A
Meat, dairy products, and nuts are major sources of dietary fat (even though some meats and dairy products can be very low in fat; overall these food groups contribute significant dietary fat). Nuts provide dietary fiber, but meat and dairy products do not. These foods contain some vita-mins but are not considered major sources. Dairy products and nuts contain a little carbohydrate but meat is almost carbohydrate free.
