Occasionaly Antibiotics can kill off the good bacteria in the intestines and allow Candidia to grow. Eating LC and cutting out sugars though can help to prevent this as the candidia eats the sugar. You might recomend she try the candidia diet found in the yeast chapter of the book more to prevent an overgrowth then treat one. She could also possibly take probiotics, though she might want to ask her doctor to be sure they won't interfer. After induction when she gets on OWL adding in plain unsweetened kifer and whole milk yogurt can be wonderful as they are fairly low carb and contain many good bacterias. Get one with at least 5 active cultures (Not Dannon whole milk) and low carbs such as Stoneyfield Farms. I typicaly eat 1/2 cup of yogurt a day and find it even helps with my weight loss I've also started adding in 1/2 cup kifer which is only 4 carbs.
