Hey Bella, I guess I missed the topic where you talked about being sick. Sorry.
Anyway, one thing about shopping carefully is you really only have to do it a few times. But for those few times, it's going to take a while. Next time you go shopping, first, make sure you've eaten well beforehand and are not rushing. Second, take a pen and paper with you.
Now, as you go along, take notes. Let's say you want to buy, I dunno, canned tomatoes. Look at not just prices (which fluctuate) but also how much salt is in there, and if there's anything else in there that maybe you don't want or don't want so much of. And just write down (I'm making up these numbers):
Hunts 1 gram sodium
Red Pack 2 grams sodium
Generic store brand 1 gram sodium
etc.
You can also make a list of foods with good things in them, such as breads:
Pepperidge Farm 12 grain - 3 grams fiber
Wonder Wheat - 1 gram fiber
etc. Whatever is important to you, take notes.
If there's any other variables, such as whether something is packed in oil or water, or whatever, write that down, too.
You may have to do this for a few shopping trips in order to get everything. Obviously, you need not do this for produce and you don't need to do it for things you don't buy.
Once you've got your information in order, organize it. Sometimes you just can't get your first choice and you really need something, so you'll need second and third choices. And you'll also need to know what is an absolute no way type of product.
Your list would look something like:
1) Starkist tuna in water (solid)
1) (tied for first place) Bumblebee tuna in water (solid)
2) Bumblebee chunk white tuna
3) Progresso tuna in olive oil
NOT TO BE BOUGHT:
Starkist dark tuna in oil
Chicken of the sea (any variety)
or whatever conclusion you come to.
Now, when you make your list (and yes, you should make a list, but that's a good thing, it means you buy only what you need, you don't throw anything out and you remember everything you need, plus most people with lists save money!), you specify -
Starkist tuna in water (solid)
Generic store brand canned tomatoes
Pepperidge Farm 12 grain bread
celery
carrots
1% milk etc.
Maybe add on the back some of your alternatives. You'll get to know what's in and out of stock. You may find that you don't need an alternatives list after a while.
Also, if you clip coupons, make sure this information is in or near the coupon holder/envelope or however you store coupons, and make sure you only clip coupons for your first, second or third choices and not for any competitors that you don't want.
We went through this exercise when I first started worrying about my cholesterol. We noted fiber, sodium and saturated fats and cholesterol in foods. I still have the lists but I know a lot of it by heart.
PS Feel better.
