Yogurt
Thanks to its high content of probiotics and lactic acid, yogurt is great for the gut. The only catch? Some folks are sensitive to lactic acid, according to Dr. Schopis. In this case, eating yogurt on an empty stomach can increase production of stomach acid, causing irritating GI symptoms. This can also destroy some of the beneficial probiotics that are found within the yogurt itself, Dr. Schopis shares.
“It’s better to eat yogurt on a full stomach, so some of [lactic] acid can be soaked up and not destroy some of those beneficial components,” he adds.
