Kizzie-
Of course!

I know you don't have a diagnosis yet, and I'm sorry about that...it can be so frustrating to not know whats going on.
I have made major changes in my diet this year and have lost about 20 pounds, and haven't really been sick. I also had to get a tonsillectomy in at the beginning of the year (tonsils were always making me sick), but then the diet and supplements like probiotics and a multivitamin have helped immensely. I used to get sick all the time, I was lethargic and lazy, but once I started eating better, and juicing frequently, I was more motivated to exercise and have been getting healthier all the time. Never get sick anymore.
I have had breathing problems for a couple of months now and have been eating strictly paleo or gluten free for the past week and have gotten my breathing under control a bit more. Not completely, but the diet, with key supplementation and breathing exercises for me, I think I can beat this thing.
Just eating a clean diet, without harmful ingredients like refined sugar and added hormones and preservatives, is proven to improve health, and sometimes cure diseases. Paleo diet is one of the clean diets known for that. It exludes bread and lots of dairy (but not all), because (for asthma) it causes inflammation and breathing episodes, but it also is high in vitamin D which helps the body restore itself for healing...
I'll keep you posted as I go along. Letting go of pizza is my big hurdle, but I still eat a lot of yummy food, I just have to pay attention to it, because I need to be able to breathe, because athsma can actually kill you, so that's why I take this so seriously...
And also just everything I have read up on carrot juice curing several cases of cancer, has made me want to juice all the time and cleanse. Our body holds 3-8 meals at a time, so when I do a 3 day juice cleanse, it just flushes that out, which could be stored toxins, etc which is why it probably cures many types of cancer.
I'm just throwing out the info as I get it and I will tell you how the diet and supplements work for my asthma down the road when I have more results.
Best
K
