Medical science or research in general, it’s all spun around to get clicks.
When people think there’s a new “superfood” or “recommendation” from doctors every week, they stop trusting doctors. In reality, the processes and recommendations are very robust and take lots of time and research to change. A study will say that “we might want to look into X” and news will run with “groundbreaking study: x is the sole cause of y”.
I’m not even an expert. Like you said “Almost every science headline was written by someone who never understood science”
