And in general, just try to eat a LOT more vegetables than the standard american diet. Otherwise the probiotics just go right through you. They have nothing to live on in your gut if you don't eat a lot of the proper fiber.
The Wahls Protocol gives a crazy high goal for vegetable consumption but if you at least aim for it you will be eating a ton more fiber than most people:
3 Cups of leafy green vegetables: kale, spinach, dandelion greens, arugula, lettuces, collards, microgreens, watercress, swiss chard, bok choi.
3 Cups of "brightly colored" vegetables or fruit: peppers, carrots, tomatoes, berries, oranges, kiwi, zucchini with skin; pomegranite, olives, prunes, sweet potaties, mangoes, yams
3 Cups of sulphur vegetables: Leeks, onions, chives, brussel sprouts, cauliflower, broccoli, cabbage, radishes, mushrooms. 2 garlic cloves= 1 cup of sulphur veggie
Make smoothies, salads, sautees... try to eat as many cups as you can. The fiber will help the probiotics you are getting in your fermented food thrive.
