Most foods contain at least some carotenoids or retinoids. Only white rice and white sugar have 0 vitamin A. So unless you are eating just white rice you are going to get some vitamin A. Meat has some vitamin a in it, but most people tolerate meat just fine. I think I don't tolerate potatoes, beans, whole grains, cocoa, nuts etc. because of soluble fiber and/or oxalates, not because of the small amount of carotenoids. If the small amount of carotenoids in these foods would be a problem I should also react bad to beef, which I don't. As you can see below beef contains some beta carotene.Btw, I should note that the products you listed contain little, but not 0 VA. Whole grains are rich in carotenoids. Bananas contain ~250 IU VA. Potatoes, if they are not white like paper, will contain carotenoids too. Nuts contain carotenoids. Even cocoa powder contains a little lutein.
Here are the retinol and beta carotene content in mcg per gram of the most popular cuts of meat in the supermarkt (excluding pork):
Beef top round: retinol= 0,03 beta carotene = 0,26
Ground beef: retinol = 0,04 beta carotene = 0,34
Ground steak: retinol = 0,08 beta carotene =0,30
Beef liver: retinol = 190 beta carotene = 8,7
Chicken: retinol = 0,44 beta carotene = -
Turkey: retinol 0,13 beta carotene= 0,01
