Yea it’s on the oatmeal boxes even. Part of what’s interesting about this study though is they claim this two day intensive(300g per day) oatmeal diet showed microbiome changes which persist for months.
Oats are for horses. Mankind basically co-evolved with Barley.

I would consider a normal bowl of oatmeal for breakfast to be about half a cup, so this is quite a bit more.
The study is not suggesting this is a long-term diet. They're saying "eat oats for all your food for two days, and your cholesterol lowers by ~10% and then stays low for ~6 weeks due to changes in your gut biome".
They're not saying eat 300g for breakfast and then eat as normal. They're not saying do this every day.
They're saying 2 days, this is what you eat, spread out to replace all your meals across those 2 days, then go back to normal.
