When I first got sick, my initial symptoms were sinus inflammation and my throat was sore all the time, and even down into my lung area. These were the initial symptoms I was having. These symptoms have become great reduced going on the candida/GAPS diets. This tells me some sort of microbe, or sugar in particular, is having a role in this. I started cheating and eating more carbs and some fruits and over 2 weeks, the sinus/throat/lung inflammation came back. Correlation isn’t causation, but it’s pretty damn safe to say there is a link.
