Yes, she's dietary restricted. Having said that, I know that the medical community can play fast and loose with these restrictions. For example, can someone who eats 7g of protein at a time take in more protein in a day than someone who tries to eat protein at a 28g a meal clip? I don't know, but I'd like to have a conversation with a naturopath that can answer those kinds of questions with research.
High blood pressure is the only thing between her and a transplant, I think diet is really her only chance to lower that blood pressure. Due to the seriousness of her condition, though, she needs a serious professional to guide her through this process - and that isn't me.
