Hello. Not sure where I should be posting this question but was wondering - has anyone heard or read or personally had success with fighting MAC with severe dietary changes alone? My sister was on the Big 3 - 18 months in she began losing vision so stopped cold turkey. She is now on a diet with NO gluten, sugar, dairy or meat. She is doing very well with her lung cavities shrinking. I, too, have MAC & want to avoid medication but her diet seems so radical hence seeking some feedback. I found nothing online in support of this. Any input appreciated. Take care.
