After going paleo, I have these food items that I don't eat anymore.
rolled oats, grits, whole wheat flour, and dry pasta (and also a pasta machine and pasta roller) Other than giving it away or eating it, are there any uses anyone can think of?
Note: I believe this is relevent to paleo because many people who switch to non-paleo suffer this dilema.
Soak it, compost it, and make other veggies out of it this coming year!
Or you can obtain some mushroom spawn from fungi.com and after cooking and cooling the iffy food and mixing it with some scrap wood... you can grow tasty food mushrooms on it
... I love the oyster mushroom spawn from Paul Stamets at fungi.com
Growing your own food mushrooms where you can find them easily later is a great hunter gatherer HACK!
You can store these grains in a bucket, and move your fingers and hand around in them. Pitchers do this to strengthen their hands, as do grip strength fanatics. Check out "Mastery of Hand Strength", the seminal volume on this!
This works for rice, but I'm not sure about the things you have. Sew it into a small cloth bag or a pillowcase, then warm it up in the microwave; then you have a hot pack for aching muscles or whatever else.
Rolled oats make a great facemask- mixed in with water and clay if you need it to be stickier. Otherwise just make it thick enough to splodge onto your face- leave it on until it dries out, then wash off with warm water. It tightens up pores and leaves the skin really soft!
Rice can be used for salt shakers to stop them blocking...
I use dried grains in a small bowl as my incense holder. Im using thin, long sticks of incense and the only way i can get them to stand upright and have their ash fall down right into the bowl is to have something like buckwheat, oats, rice, etc as a bedding. Works like a charm.
Arts and crafts, like people make art out of gingerbread or cake ( https://www.groveparkinn.com/gallery/National-Gingerbread-House-Competition ).
