Passage Summary: Forget the old advice about calcium; if you want strong bones, you need to eat plenty of vegetables, cut back on meat and dairy, and stay active with exercises like walking.

Conclusion: Osteoporosis is prevented by a low-protein, plant-based diet and weight-bearing exercise rather than high calcium intake.

Reasoning: Bones require physical resistance to thicken, and the nutritionist claims specific dietary restrictions are essential for bone health.

Analysis: Since this is a 'Strengthen EXCEPT' question, four of the answers will provide data supporting the nutritionist's unconventional claims, while one will not. You should look for an answer that is either irrelevant to bone density or perhaps even suggests that calcium or meat/dairy are actually beneficial. The nutritionist makes several distinct claims, so support could target the diet, the exercise, or the dismissal of calcium.
