I think all of us with ME/CFS ought to maybe consider stocking up with some things if we can do it, and afford it. It would be good to limit our time out in crowds/ shops/stores etc.
I already have stocked up on some food and supplies, simply because when I first noticed this in late January, I wasn't quite sure how it would affect our economy, work force, store openings etc when it came to my country, which I knew it would.
Low carb is tricky. It depends how strictly low-carb he is. A lot of store-able foods have carbs. But what about quinoa? That's a seed (not sure of carb content)
All fresh meats and fish freeze well and will keep some time at -18C
There is certainly a lot of canned fish to choose from. I wonder if he would like some of the canned meats? Some are not so bad, though that's from memory as I don't eat meat now (I just went off meat, is all) I remember some chicken curry in a can which was tasty....
There are hotdogs (not the best nutritionally but okay when you are hungry and better than nothing) Canned hams (again nothing like the real thing but better than no food)
Canned veg is not too bad. I sometimes eat it just for fun. I LOVE the "cut green beans" and processed peas for some reason!
If the store has a Polish range, then some of the Polish stuff is really excellent, and they have more variety (meats, vegetables, sauerkraut etc)
I bought lots of cans, dried, and frozen foods over the past few weeks, plus other supplies. But I have no dietary restrictions. So it was basically anything that would keep for at least a few months, and with cans at least a year (mostly longer) Lentils, beans, rice, noodles, pasta, stock cubes, peppercorns, salt crystals, plus canned everything...fish, quiches, vegetables , frozen fish, bread, butter, blueberries....etc.
I also blanched cabbage, green beans, broccoli, carrot pieces and cauliflower florets and put them in my freezer.
I don't know how the virus behaves with heat, but have been eating cooked/steamed vegetables.
The one thing I do now though is either wipe down everything non-porous (wearing gloves) with a hydrogen peroxide mix and dry before storing it. I buy veg which is wrapped in plastic film, and will strip the film off carefully, then wash hands before re-bagging it to store....then wash hands again. Normally I wouldn't opt for plastic wrapped veg!
Fresh fruit....tricky. But I wash it in cold water and scrub lightly, then risk it. I even scrub things like oranges, bananas and mangoes, even though they are going to be peeled.
