Leeks, mustard greens, broccoli, kale, cabbage, garlic (LOTS OF GARLIC), and a heavy dosage of spices work well on a candida diet. A couple of the spices and herbs that we use in cooking have mild to high anti-fungal properties to them (MORE GARLIC). Start cooking everything in extra virgin coconut oil, yes it's expensive but my god that stuff will kill fungi dead in it's tracks. Try keeping record of how many carbs you are getting in a day, if you can drop down to the 30g and under range while keeping the majority of your energy intake coming from fats then you'll slip nicely into ketosis (especially with all of the coconut oil consumption) which will drastically cut down on the on demand energy available for candida. While you might be able to get less strict later on for the time being really attempt to nip this in the bud and avoid ALL Fruits, Grains, Legumes AND Dairy. Mushrooms are perfectly safe to consume in spite of what some people will recommend. Most fungi produce compounds to kill off competitive fungi and bacteria also produce these fungicidal compounds. Take lots of probiotics as people with this candida crap always have some very offbalanced gut bacteria, as you build up good bacteria it will compete with the candida and also help to beat it back.
Back when I used to have that annoying "itch" deep in the skin of my feet/hands/scalp/knees/ears and I finally went on a ketogenic diet within about a month I had a massive diet that made it look like I had flesh eating disease in certain areas of my body as all of the toxins were very quickly dumped into the skin. Since then however the itching has finally gone and the damage has healed.
