I haven't changed any of my red meat intake, but I don't eat a lot based on convenience to cook it, and I do eat a meat source and an egg daily. I love steak, and would probably have it once a week if my husband would bbq it (because he does it perfectly without charring).
There are many options for iron food sources...
Your girlfriend can start cooking foods in a cast iron pan...that will increase the numbers a bit. Even if it's to cook apples or spinach or whatever...the iron will transfer to the food.
She can also make sure she's getting enough vitamin C...eating vitamin C rich foods with iron containg foods will help her utilise them better.
Curious..what's her diet like daily?
Have you checked out lists of iron food sources? and the amounts?
Is she taking vitamins that include iron.
Hope this helps.
