Sauerkraut is a good food to eat for your gut and to help promote good gut health.
Sauerkraut contains beneficial probiotics which is good bacteria that aids in good healthy digestive health so your gut health improves.
That good bacteria or probiotics when fed to your gut works to help to combat inflammation so you'll have better healthier digestion and won't have as many digestive issues as before.
I eat homemade sauerkraut which is full of beneficial probiotics and I've had much better digestive health as a result.
Sauerkraut is also a very good food to eat and makes a great addition to just about anything you eat including hamburgers, hot dogs etc.
