Changes in diet with diarrhea?

So I started having diarrhea about two days ago. I recently transitioned into the vegan lifestyle, however, decided one day that I wanted tacos. They were made with hot and spicy seasoning. Since I haven't had beef in a long time I thought I might have some issues. I had made a vegan rice recipe earlier that day that included tons of vegetables, bean sprouts and a spice I've never used called turmeric. I had made a large batch and was eating it for a few days. That's when it started. What happened didn't kick in until later that evening during the night. I had stomach cramps (that you would get if you needed to have a bowel movement) and had diarrhea. The next day, it got slightly better, yet I became somewhat constipated. so I decided to take a laxative. After taking the laxative, I have a few bowel movements, less than usual if one were to take a laxative. Then last night I ate more spicy noodles, but I had loose stools through out the day, and again today.

Other things I've eaten:

A whole bag of radishes, tons of fruit (oranges, bananas, pineapple, and apples), cliff bars, raw vegetables.

Also, I've been eating a small amount of dark chocolate.

I do extreme exercises daily, and have recently lost some weight (on purpose), but I just thought it was weird that I had acute diarrhea.

I want to know if spicy foods and excess fruits can cause diarrhea?
