Thank you for the links. Heard forever that dandelion greens are high in vitamins, so antioxidants make sense. I'm definitely interested in that one. Back to best eating plan--I read on 2 different sources that a high carb diet creates extra work for the lungs. I don't remember the sites and there was no information about the physiology behind the statement, so I remain skeptical. I asked my pulmonologist on my 2nd and most recent visit. He said "that's beyond my scope". So I continue to make every effort to avoid processed carbs--white bread, white rice , white flour products, fruit juices and added sugars. I don't avoid carbs because I don't want further weight loss and make sure I get adequate protein. Stay well!
