I would like to see Diet/Lifestyle researched further. Some time ago I found a website indicating that hydrochlorhydria (lack of stomach acid) is frequently present in rosacea patients. Then I found another website indicating that salt is necessary in order for the body to manufacture stomach acid. I had rosacea at the time and had also been on a low-salt diet for many years. I wondered if there was a connection and began increasing my intake of salt. After several months my flushes were less & less frequent and eventually disappeared altogether.
A deficiency of salt may be rare, but there are a lot of people who have high blood pressure, or who are simply dieting, and may be on long-term low salt diets. It could be the cause for some people.
