Health S.O.S - Calling All Recipes

A very good friend of mine has been told that for health reasons she must adhere to a particularly strict diet for the next twelve months. Now, of course, she will be obeying the good doctor’s orders, but I would dearly love to be able to assist her to make it through the twelve months without being entirely deprived of decent food! The problem is this: I am finding it very difficult to find recipes that exclude the key groups. She has been told to avoid anything with gluten, yeast, lactose, wheat, sugar and/or preservatives as they are interfering with both her iron and folate levels (and she is therefore anaemic). While I can find recipes that exclude some of these groups, I’m having trouble finding recipes that exclude all. I’m looking for any types of recipes – both treats and everyday meals. Can someone please assist? I would love to be able to help her out. Thank you!
