I follow a 'weed and seed' protocol to manage the starch-loving bacteria: I alternate 6-8 weeks of probiotics ("seed") with 10-14 days of herbal antibiotics ("weed").

My herbal antibiotic is usually berberine, and sometimes oil of oregano, peppermint oil, and caprylic acid.

After a few rounds I was able to greatly increase my starch intake.
