There are polysaccharides, disaccarides, and monosaccharides. From my research polysaccharides and disaccarides (like bread and such) ferment longer in the gut, where monosaccharides can absorb more quickly. Polysaccharides and disaccharides are longer chains and take longer to break down whereas monosaccharides absorb more quickly. For someone with Candida, monosaccharides are not ideal because it means the Candida can absorb more quickly, and depending on where it has grown to e.g. moved its way into your small intestine, it can be bad eating sugar. From my understanding, Candida is typically located in the colon, but it works its way up into the small intestine and else where, sometimes even in the mouth when it gets pathogenic. If it is not within your small intestine, monosaccharides in small amounts I presume would be absorbed before they hit the colon. I would try to avoid sugar in general and when things become manageable and never eat processed sugar if you can keep from it. Since we don’t have probes to tell, and we are all going based on best guesses and presumptions, its best to just avoid them until you get a feel for whats going on. I don’t think 1 gram will kill you so long as your meal is small. I see there are three versions of this diet, that range from the very restricted diet being 15-20 grams restriction each day of carbs to the higher end of 100-125 for the less restricted diet.
My theory is that if you eat a small amount of food at a time, your body can better break it down. When you eat tons of food in one sitting, you can transfer undigested food into various areas in your intestinal tract and if it has a little bit of sugar still in this mush, you feed pathogenic microbes. Until recently, I’ve followed this rule and have had good results compared to how I would eat before. The problem with the Candida diet and GAPs diets is they make you hungry and can make you want to ear larger portions. You have to be careful because of it not all properly being digested right. We already have compromised digestion as it is.
