Passage Summary: We can now put iron in salt to fight anemia, and since everyone eats plenty of salt anyway, this plan should actually work to get iron into people's systems.

Conclusion: Adding iron to table salt is a viable method for reducing global rates of anemia.

Reasoning: Salt is a universal dietary staple, and current consumption levels are high enough that fortified salt would deliver a meaningful amount of iron to the consumer.

Analysis: The statement in question serves as a premise that supports the feasibility of the proposed solution. If people only consumed tiny amounts of salt, fortifying it wouldn't provide enough iron to make a difference. By establishing that consumption levels are 'significant,' the author provides a necessary piece of evidence to conclude that the fortification process 'could help' solve the problem. It functions as a supporting fact that bridges the gap between the technology and its real-world effectiveness.
