is red meat allowed and cheese know cheese not vit d 

I’m not really a red meat eater, but I did have ready made lasagne and chilli con carne when I was on chemo (I was not up to cooking myself then). I did have cheese in mashed potato etc, as I got mouth ulcers and so ate a lot of soft food. But it might depend on your type of chemo perhaps, and how you react. Your breast care nurse and oncology team will answer these questions for you, depending on your plan.
