Some people here are supplementing with betaine hydrochloric acid and pepsin, which are secreted by the stomach of healthy people. Vitamins and minerals involved in stomach acid production, like zinc, can help too.
I’m glad you’re feeling better, but if you continue eating junk food, candida’s only going to be one of the things you’ll need to worry about. Poor nutrition and toxins are the cause of pretty much all non-genetic degenerative diseases, and genetics accounts for only about 5 in every 1000. That’s why I really feel the diet is worth the commitment, and I feel lucky I was able to make that realisation while I’m still in my 20s.
By the way, how do you know your diet has improved your stomach acid levels? Are you getting warm feelings or acid reflex or something? That would be a sign that something is wrong.
