Rethinking red meat: Are dietary guidelines missing the bigger picture?

Research highlights the critical role of red meat in providing essential nutrients like iron, zinc, and B12, particularly for vulnerable populations, while questioning the low-certainty evidence linking it to chronic diseases. It urges policymakers to balance health, environmental, and economic factors when considering dietary guidelines.
