Bread

https://twitter.com/ScottAdamsSays/status/1714314926679105857 - I quit eating bread products several months ago and had the following outcomes.

1. I drifted down to my ideal BMI without any conscious dieting.
2. My continuous full-body inflammation and aching that I assumed was age-related disappeared completely.
3. My sinuses opened and my sense of smell returned. (I lost it 20 years ago, but sometimes it returns. Seems to be staying this time.)

I recommend experimenting for one month without eating bread. See if anything improves.
