Stop throwing your food away.
Maybe you know the routine. Every so often, I go through my refrigerator, check labels on the items, and throw out anything that’s a month, or a week, or maybe a few days past the date on the label. I might stop to sniff, but for my whole adult life, I’ve figured that the problem was obvious — my jam or almond milk or package of shredded Italian cheese blend had “expired” — and the fix was simple: Into the garbage it goes.
This habit is so ingrained that when I think about eating food that’s gone past its date, I get a little queasy. I’ve only had food poisoning once or twice in my life, always from restaurants, but the idea is still there in my head: past the date, food will make me sick. You’ll probably never catch me dumpster-diving.
