As for the news, I can understand the notion of a diet. I try and catch at least some of the PBS Newshour each day. It’s the closest thing I’ve found to unsensational, non-editorialized, old-fashioned reporting. If I’m pressed for time, I catch the news summary.
Truthfully, I consume a bit more reporting than just that, but when I start feeling overwhelmed, the PBS Newshour is my diet.
