PrepTest 86, Section 2, Question 7
Nutritionist: Contrary to popular belief, a high-calcium diet does not prevent osteoporosis (decrease in bone density). Rather, a low-protein diet with an abundance of fruits and vegetables and a minimum quantity of meat and dairy products is essential for the prevention of the condition. Weight-bearing exercise, such as walking or climbing stairs, is also essential, since bones thicken when they withstand regular resistance.

Each of the following, if true, would support the nutritionist's view EXCEPT:
Astronauts who have lived in the weightless environment of space have exhibited decreases in bone density despite vigorous physical activity.
Certain medical therapies that do not involve special diets can be effective means of preventing osteoporosis.
Populations in countries with the lowest per capita rates of protein consumption have some of the lowest incidences of osteoporosis.
Arctic peoples, who consume large amounts of calcium, exhibit one of the highest rates of osteoporosis in the world.
The incidence of osteoporosis is unusually low among strict vegetarians with low-protein diets.
