2. Bacteria & Why It Matters
As I said, there are good and bad kinds of bacteria. As you can probably guess, the good allows your gut to function properly and do all those good things that you gut should do. The bad not only inhibits the gut from functioning as it should, but also causes a whole lot of digestive problems ranging from bloating to diarrhea.

Additionally though, gut health greatly impacts your immune system — something which you probably wouldn't associate with digestion. In fact, a huge part of your immune system is located in your gut! Having poor gut health can lead to a variety of conditions such as arthritis, depression, anxiety, diabetes, acne, and more. This all ties into chronic inflammation too, which develops from poor gut health and non gut-friendly foods.
