it seems that my vegetables spoil and lose their freshness incredibly fast. how can i mitigate this?
my vegetables seemed to lose their freshness and begin to spoil in about 2.5 - 3 days after purchasing them.
They are supposed to. Good food, goes bad. Buy less, more often to get the most nutrients out of them, every moment after harvest, unless the food is instantly frozen, you are losing nutrients. I buy a mix of fresh and frozen veggies so I don't have to go to the store too much.
Using the crisper drawer in your fridge will buy you a little more time. Lettuce should be put in a bag, even in the crisper. You can also get a few more days out of some items if you wash and dry them before putting them in the fridge. If you buy bunches of carrots or beets, taking the tops off will help keep the moisture in the root, instead of wicking it away to the greens. Fresh herbs and green onions can be stored in a jar with a few inches of water in the bottom to keep them fresh like you would a flower bouquet.
