The carob sounds great I suppose, especially if someone really loves their chocolate. Fortunately I can and have lived without chocolate both before and since going on the Candida diet. I looked up the information on carob, and found that it has 12 net carbs for every 1/4 cup of the powder. For my personal diet, this would be too high a carb content for one item I’m afraid.
But good luck, I sincerely hope it works for you.
