The only options I can find that are not loaded with glyphosate, sugar or salt, and that also still have fiber in them are private label or from companies not included on the graph.
Post, General Mills, and Kellogs don’t sell organic options with their own branding, so all their stuff has glyphosate applied at harvest (search for: round up drying agent)
Kellogs owns Kashi which (I think is still organic), and the local stores don’t carry Kashi stuff that meets my requirements any more.
The manufacturers with reasonable offerings that I know of are: Amazon (365 whole foods market brand), nature’s path (privately held) food for life (38 employees; independent), and probably trader joes.
They all would either be excluded from the analysis in the article or put under “private label” which is increasing slightly over time.
However, their combined marketing budget is some tiny fraction of the companies pumping out unhealthy garbage.
Maybe if finding non-terrible cereal wasn’t a complicated project, then sales would start ticking back up.
