My mom just had a blood test because she is going to start a clinical trial - don't know very much about it because they didn't provide much information at first, will post here soon as I know more. Also wish I knew more about what they found - they had to do a few tests, maybe just to be sure her blood was clear of some other meds. They would have known if she was very deficient in something obvous like iron though. Anyway, she should probably have her blood checked more and speciically for nutritional levels.
But she cut out red meat a long time ago - it didn't make her feel good. She eats a lot of fish (in part just because she lives in London) and she eats yogurt almost every day in her granola. She takes the b vitamins, calcium, things like that. We cut out anything that could be an immune booster in case it could make anything worse. She drinks green tea, other tea, also red wine and coffee, of course - can't lose all the fun in your life. Anyway, her diet is not bad at all, but she obviously needs something more than just a good diet at this point.
Anyway, thanks for the input. Keep it coming!!!
