Not really sure what you are asking about here - the word candida is used to describe a condition caused by what many people believe to be a "yeast infection gone crazy", so to speak. Most sites online can give you a pretty accurate accounting of what happens - yeast proliferates, and begins to grow like a weed in your gut, living off the food you eat. Sugars or carbohydrates make it grow best and fastest. When it reaches it's "adult" stage, to use lay terms, it sends out roots to embed itself into your intestinal walls. People with chronic candida of this level, often exhibit the symptoms you describe because as the yeast lives on inside of you, it gives off wastes toxic to the human body as it feeds. Many people become or are allergic to these toxins, and the symptoms are examples of this.
Some physicians believe that "dead" yeasts ( such as those found in cooked bread) cannot cause yeast infections, but others believe that if you have a sensitivity to the yeast, even dead yeasts can act as a trigger to set off your sypmtoms. Most people who have candida infections avoid yeasts or yeasty foods altogether based on this hypothesis, those who feel otherwise don't. You may also have an allergy to molds or yeast. If you are getting the symptoms you describe, you should probably completely avoid all yeasty foods, and perhaps even try a strict antifungal diet for a while. reintroduce the foods you think are suspect one at a time to identify your allergin triggers.
If you are a candida sufferer, then the problem is more complicated. Just avoiding yeast won't heal you, you will have to work to cleanse your system, reduce your sugars and carbs to limit yeast growth in your gut, and reintroduce good flora using probiotics.
