Hmm, I got it in zones 5&6 and the guy says it's respiratory. I don't smoke at all. I have had a cough recently but I dunno what's causing it,. Could be mold in the house.
I've also got it in 7 (heart) and while I do have blood pressure sometimes, I've actually had multiple tests done to check my heart and doc says I'm fine.
As for what I've introduced to my diet, I'm eating more oats, milk, and bread than I was previously to add calories.
I've heard that milk and grains can cause/inflame rosacea but it's cheap and I can't really afford to go on a diet that doesn't have it. Besides that I just stumpled upon kefir and that stuff is too good for you to not eat.
