PrepTest 69, Section 3, Question 5
Physiologist: The likelihood of developing osteoporosis is greatly increased by a deficiency of calcium in the diet. Dairy products usually contain more calcium per serving than do fruits and vegetables. Yet in countries where dairy products are rare, and fruits and vegetables are the main source of calcium, the incidence of osteoporosis is much lower than in countries where people consume a great deal of calcium from dairy products.

Which one of the following, if true, would most help to resolve the apparent discrepancy described by the physiologist?
A healthy human body eventually loses the excess calcium that it takes in.
Many people who eat large quantities of fruits and vegetables also consume dairy products.
There are more people who have a calcium deficiency than there are who have developed osteoporosis.
People who have calcium deficiencies are also likely to have deficiencies in other minerals.
The fats in dairy products tend to inhibit the body's calcium absorption.
