There are a few different versions of candida diets out there, and they don’t all share entirely the same guidelines. Based on the diet on this website, I’d make the following suggestions:
Honey shouldn’t be eaten while you’re on a candida diet. It, along with other forms of sugar (even naturally sourced sugars) feeds the candida in a big way. Hold off on sugars until you have eliminated the overgrowth in your body.
Both yogurt (Greek and American styles) and kefir do contain live probiotic cultures. Make sure you’re using plain unsweetened, rather than sugary, versions of these.
If you are experiencing an allergic reaction to fish I would definitely recommend against eating it. Some people do have seafood allergies.
Most fruits should be avoided at first (a bit of lemon or lime juice is okay) due to the high sugar content. Once you have eliminated the candida you can add fruits back in moderation, beginning with low sugar varieties.
Most vinegars should be avoided on a candida diet, as well as other fermented and yeast-containing foods, as these promote the growth of candida in the body. Apple cider vinegar is the notable exception, which has antifungal properties.
I highly recommend reading through the diet described on this website. There’s a lot of detailed information provided here.
