For The Past Few Month I Have Been Experiencing Chronic

For the past few month I have been experiencing chronic diarrhea. No constipation. It usually smells like the food that I ate. Until last week my diet had been extremely poor. Fast food everyday pretty much and lots of soda and other bad things. For almost a week I have did a 180 and am eating the healthiest stuff I can find. Yesterday I started taking a probiotic and enzyme supplement. So I am just wondering if my horrible diet is the cause of my diarrhea and I just need to wait until my body gets used to the good food and restores my digestive system. Other than the diarrhea I feel very healthy, no abdominal pain, no blood in stool. Thank you
