CH, I agree with others that probiotics are desirable, two hours after taking the antibiotic. (When I took a Zpack for a sinus infection, my doc said take the probiotic a couple of hours after.)
Coconut is good for killing off yeast. You could try making pina coladas with SCD-legal pineapple juice, the SCD-legal " light coconut milk" from Trader Joe's, and add a tablespoon or two of SCD-legal coconut butter (the kind I have is Artisana Organic Coconut Butter). Each tablespoon of coconut butter is 93 calories. 1/3 cup light coconut milk is 50 calories. More info about coconut below:
"One of the good things about lauric acid in virgin coconut oil is that it kills lipid-coated bacteria but does not appear to harm the friendly intestinal bacteria. The MCFA (medium chain fatty acids) in coconut oil also have antifungal properties so not only will they kill disease-causing bacteria and leave good bacteria alone, they will also kill candida and other fungi in the intestinal tract, further supporting a healthy intestinal environment."
