You didn’t mention if you already got candida feeding on your guts or you are asking it just out of inquisitiveness, so what I will tell here is a more or less generalized version of alkaline food types and not the duration you need to continue with them. Usually, a month-long tenure with probiotic supplements proves enough for mild-to-medium infections; if yours is more than that, be on them for another 15 to 20 days and see what it comes up to. However, alkaline foods are not enough; you also need to bring certain lifestyle changes (adequate rest i.e. 7 to 8 hours of sleep, cutting down on stress etc.) and complete avoidance of the typically American diet, which is both toxic and acidifying. That means:
No processed/refined sugars, not even artificial sweeteners.
No refined grains.
No processed meat and/or dairy.
Only this way you can gain back balance with alkaline foods.
The first in this list are root vegetables, but not sweet potatoes, beets and carrots. These are rich in sugar, so they feed candida instead of starving them. Turnips, rutabaga and horseradishes are what you must target. You can introduce potatoes but only after the first 20 days and if you are feeling better. Beets and carrots will come much later; as late as after the first 45 or 60 days. Do not start them as soon as the leaky gut heals. That will be back to the same old story.
Next are cruciferous vegetables; the kind with leaves all around. There’s nothing much to say on them; we all know it and broccoli, cauliflower, cabbages and Brussels sprouts come under this class. You may even make sauerkraut out of the cabbage and pickles out of the other three.
The third type is the leafy greens that will give you a lot of Vitamin K, folates, minerals, antioxidants and other phytochemicals and fiber. They also improve digestion; however, if yours has reached rock bottom, you’ll need additional herbs to restart it. There are excellent posts on resetting your digestion in this forum.
I mentioned probiotics earlier but they are not worth a dime if you can’t feed them or provide an environment that’s suitable for colonization. So add mineral water, onions, garlic and Cayenne pepper to the list; apart from the FOS, they comprise vitamin A which is a potent stress reducer.
And lemons! I should’ve mentioned them earlier (sorry I missed out) as natural disinfectants and an amazing cure for hyperacidity and viral infections. Lemons are also good for the liver and you can have as many as you like, squeezed in plain water or as a dressing to green salads (cucumbers are good too, another thing I forgot to mention) with sea salt. 80% of your food must comprise what I told while the rest should be lean animal protein (eggs and white meat). That should take care of things well.
