Passage Summary: Some babies have a yellow tint from a blood pigment. While some doctors want to lower the pigment levels to prevent brain damage, others say it's fine to leave it alone because the brain naturally protects itself.

Conclusion: Newborns with high bilirubin levels should not necessarily receive treatment to lower those levels.

Reasoning: The brain possesses natural defense mechanisms that typically prevent bilirubin from entering and causing harm.

Analysis: To support the second group of doctors, we need a reason why high bilirubin might actually be okay or even beneficial, or more evidence that the natural defenses are extremely reliable. We want to bolster the idea that the risk of brain entry is negligible or that the treatment itself might be worse than the condition. Look for an answer that highlights a benefit of bilirubin or a downside to the intervention.
