Passage Summary: Because some health studies disagree with each other from year to year, the author thinks we should ignore all experts entirely.

Conclusion: Expert opinions are completely worthless for making personal health decisions.

Reasoning: The author points to the fact that different health reports sometimes offer contradictory advice about substances like coffee and sugar.

Analysis: The argument suffers from a massive overgeneralization. It takes a few instances of conflicting data and uses them to dismiss an entire category of knowledge. It's a bit like seeing two weather apps disagree on the chance of rain and concluding that the entire science of meteorology is a scam. Look for an answer that highlights this 'all-or-nothing' thinking or points out that the author is drawing a sweeping conclusion from a very limited set of contradictions.
