Part of the PR about oats is history - up to a century ago it was one of the most complete single foods available. Not only that, but it kept for years if dry, and if necessary could be eaten for weeks after solely overnight soaking in cold water.
When my ancestors emigrated from northern England two centuries ago, the typical death rate from disease during the nominally- 6-week voyage was 25%. (Later it rose closer to 50%, especially from Ireland.) They were advised to bring enough rolled oats for twice the expected duration of the journey. Nothing else. Not only did every last one survive, there is no family record of any significant illness!
IMHO, oats should still be part of any quality diet.

80% of those who came over on the Mayflower were dead within 2 years of their arrival in the New World. What? They didn't think enough to bring along some oats?
