If you are not lactose intolerant, powdered milk could be a good alternative to still have proper intake of calcium and can also be used when eating cereals. Since you're diabetic, find a product of that is low in sugar. Fresh egg can last a couple of days and it's also quick and easy to cook. Canned tuna has no carb but rich in protein so it can be a great addition if you can eat those type of food.
Powered milk may have too much sugar.
I would likely use :
canned tuna
canned chicken
spam
a jar of solid coconut fat
boxed salt free chicken broth
bottled water and water filters
vitamins
powered calcium
72 and 88 percent chocolate bars
a few bottles of vanilla vodka.
plus I have 2 fig trees which will make about 30 quarts of fig preserves.
as I said this is more for the new pandemic trick they may pull on us then it would be for a war.
also in case of a hurricane
I do have 3x 20 pound cans of propane and a generator that uses propane.
