I think taking a good probiotic and eating yogurt helps. I also take omega-3 fish oil which helps against inflammation in the body (and it is good for the heart). And personally fiber helps (this is not the case for many people). I feel much better if I have a daily dose of oatmeal.
I also avoid food that is high in fat, ground beef, fried foods, fast food and food in general that is not healthy.
I do these things combined with my medication.
HOpe this helps!
