Years ago, I read an article that oat meal binds with fat, making
the fat less available for energy. This leaves a question for me.

I would take the same things that you guys have suggested.

I would add, tea bags, instant coffee packet, bullion cubes
(double wrapped). Drinking water is important for health and
tasty water is good for morale. Also I would add individual
packets of jam, sugar, honey.

Put all these in tin cup, for protection.
