Have i done enough?

[Ladybird60]

Hi
I am new.
Regarding stocking up. I have a lot of tins of soups, beans etc. As lock down approached i built a stock of meats, frozen vegs, fish, pizzas, chips etc - freezer is full. My strategy is i use oldest first and keep replacing as i go. So it never depletes. I keep several loaves of bread frozen.
I venture out for one shopping session each week. I go niwhere else. I get fresh food so i never deplete my main stock. I don't like ready meals. I focus on meat, fish, eggs and vegs. A high level of nutrition is vital to keep us healthy. I am prepared to ration us to one meal a day when shortages begin - i am sure it is only a matter of time.
I realised i must get bottled water so that i will begin building up now. I ordered tins, pouches and dry food for my dog - about 6 months worth. I've got a supply of flour so we could bake bread for a while if need. I am a good cook so i am confident i can use ingredients economically.
I've avoided rice and pasta which in my view are not actually very nutritious.
What else do i need please advise?
