Best Foods to Manage SIBO Effectively
Managing SIBO (Small Intestinal Bacterial Overgrowth) requires careful food choices to reduce symptoms. The best foods include low-FODMAP options like zucchini, spinach, and chicken. These foods help reduce fermentation in the gut and are easy to digest. Avoiding high-FODMAP foods can prevent bloating and discomfort associated with SIBO flare-ups.More from NIH: IBS
