I've been buying, storing, and eating popcorn, rice (brown and white), groats, millet, and all manner of beans by the 50lbs or 25lbs bag for years. I keep them dry (to protect from humidity) and covered (to protect from bugs) in generic plastic 5gallon buckets covered with Gamma Seal Lids (you can google them,
very user friendly). There is not enough fat in these products for rancidity to be an issue. Moisture of course
is an issue, hence keep them dry. The rice is the only item that will be attractive to bugs (little moth-like creatures), hence another reason to keep rice sealed up. Buying in bulk sometimes gets me a 10% discount on top of waiting for a sale price. This practice helps keep my daily food cost near or below $5/day here in SoCal as long as i avoid packaged, canned, processed products and minimize high fat products (plant milks, nuts, seeds, avocadoes, olives) which are all relatively high priced. It also prepares for disasters which might jeapardize food availability.
I once brought home a 50lb bag of popcorn from Smart & Final and the popped corn tasted off; it was because somewhere along the way from field to grocer, the popcorn had been exposed to moisture and had become mildewed. I was allowed to exchange it. Actually the popcorn is sometimes too dry and the quality of the popped product can be improved by putting an open container of water in the storage bin where it is slowly taken up by osmosis...fluffier popcorn.
Regarding food expence, you have to remember that i am relatively healthy, not poor, have a home with kitchen, gas, electricity, water, cooking tools, and live in CA which is
not only the what?, maybe something like the 6th or 7th largest economy in the world (yes, a state economically bigger than most whole countries)
but also the breadbasket (vegie garden) to this nation and so all things healthy and unhealthy are readily available here. So when you hear about someone selling an "Eat On $4 Per Day" book, think about the context and the choir they're preaching to. Life can change in a heartbeat but for now I'm in the right place at the right time with the right Doctor* living like a King, but without the gout. If there were anything to the whole karma belief system, i would have to have been an angel in a previous lifetime.
*In light of yesterday's webinar, I will think of him as Dr. Starch.
