What I was trying to gather, when I asked if you were "low carb", was whether or not you were eating sufficient quantities of starches in your diet. If you read the recent Candida thread, you would have seen the evidence on why low carb diets don't work against yeast/Candida over the long term. If you are avoiding "gluten, dairy, sugar, and yeast" but not eating enough starches, you aren't fermenting and that means likely in or near ketosis with an alkaline gut — which will ignite yeast/Candida and promote fungal infections, particularly since yeasts are eukaryotes and all eukaryotic organisms have mitochondria that can eventually adapt to and absorb ketones as a prime fuel source. Plus, those acid-producing SCFAs kill pathogenic yeasts! So, that's what I was going after. And if you are eating sufficient quantities of starch, then you would already know if you can tolerate resistant starch because a diet with sufficient levels of starch already provides ~8g of resistant starch per day! Before you dismiss a moderate-starch diet, consider the fact that many low carbers have resolved their fungal/yeast infections by simply adding a good amount of starches to their diets. And finally, a pattern has emerged from reports on freetheanimal.com where the people who claim that RS doesn't work for them tend to be very low carbers who don't eat enough "safe starches". It seems that something is off with the guts of these low carbers. At this point, all fingers are pointing to an alkaline gut/intestine that promotes pathogens with RS probably just feeding the bad guys. But, if you eat enough (RS-rich) fermentable carbs your gut starts fermenting and shifts to a more acidic pH that inactivates pathogens and promotes beneficial flora. But, of course, doing that requires eating foods that contain RS.
