This info slide above describing junk food is possibly analogous to much/most of the news-media output on the political stories of the day. There does seem to be a social-circadian function to these stories that are "on the hour, every hour" so to speak, a collective rhythm to the day for peoples' establishment of their context to the world around them?
But if you're interested in more than this, then you may find that the quality of information is not very high for increasing understanding of politics apart from the more emotional stimulation and submersion socially within the constantly, ever-washing news stories.
The "good news" is that curated properly, there is a way to select (visibility problem) from this "roiling sea of emotion and excessive information":-
1. State of UK Politics
2. State of Brexit
Public Law for Everyone: Brexit | On why, as a matter of law, triggering Article 50 does not require Parliament to legislate
This sources will more than suffice for an entire week of political news-media at the very least, if spaced across an entire week for the weekly intake of news - at the very very least!
