I get the lactose free milk. It’s higher, but since I figured out that regular milk bloated me up like a balloon, it’s been worth it. Didn’t know aged cheddar was low in lactose; thanks for telling us about it.
I count on something that's at least 9 months old ~ and just about every cheddar of any quality on sale at Safeway is going to be that old ~ even if it's not marked.
Cream cheese is out. Blue cheese is out. SOME Swiss is a problem ~ look for the age ~
Something to watch for with cheese is the natural anti-cholesterol chemicals. Baby cows need them so they can drink their mothers' high cholesterol dairy product! Those chemicals are still in there, so if you eat a lot of cheese and also take an anticholesterol drug you might "overdose" and what will happen is you will get intramuscular pain, and recurring but intense pain in your feet and hands.
You can cut back on your medicine or your cheese in that case!
