You are correct they are healthier, at least until they go rancid. ;-)
I havent been stock piling (I probably should) but as I live alone and live in a small garden apartment with very limited storage space - tiny kitchen, tiny and very few cabinets ; ( , I dont have a lot of room to do so. But I do buy brown rice and whole grain pasta, just not more than I can use over a few weeks or a month. I have stocked up on those Uncle Bens brown and basmati pre-cooked rice in the vacuum packs when they are on sale and I have coupons - I dont know what the long term shelf life is, but they are convenient to make a quick and healthy meal.
Plus evident that every couple of months, even though Ive not seen not one single bug in my apartment since Ive lived here, the management has had a pest control company come in for a general spray several times recently. About eight weeks ago they left roach baits in my kitchen cabinets and it freaked me out I really didnt like roach baits in my cabinets where my food and dishes are stored BTW! Then they came in about two weeks later to spray again. In fact I came home just tonight and there was yet another notice taped to my door that the pest control company was going to do another general spray in my apartment tomorrow the same notice was posted on everyones door BTW. This leads me to think that, while Ive never seen bugs (roaches) that there is a problem in my building. ; ( and it really pisses me off because I keep my apartment very clean and I keep all my food stuffs like flour, cereal and rice in plastic containers with tight fitting lids rather than in open bags or the boxes they came in.
