When you experience a slip up on the diet, all you can do is take up where you left off and wait to see how or if it affects your Candida symptoms.
If you’ve never see beets on a not-allowed list before and you’re not familiar with their content, your mistake is understandable. Beets do contain sugar, and have a glycemic index of 64, which is more than a banana and about the same as a serving of mashed potatoes.
As far as the carob is concerned, there are different varieties of carob with the average amount of carbohydrates per tablespoon of unsweetened carob powder being about 6 grams. It’s full of vitamins and nutrients, and does not contain the same chemicals from the caffeine family as chocolate does. So personally I can’t see why occasionally using it could be damaging to your treatment.
