Gut Wreckers: 10 Foods That Can Harm Your Digestive System

Your gut isn't just your body's digestion hub; it's a bustling ecosystem crucial for overall health. According to healthline, your gut is home of the gut microbiome, which is the collection of trillions of bacteria and microbes that live in a part of your large intestine. This microbiome contains a balance of both beneficial and harmful bacteria, and when it is in balance, should be functioning properly. However, when your gut microbiome is off balance, it can negatively impact things like your immune system, digestion, and mental health.

These are 10 foods that can wreak havoc on your digestive system and throw your microbiome off balance.
