Help near frequent diarrhea?

I get diarrhea at most minuscule 3 times a week usually within five minutes after intake meals containing meat. I've other gotten sick after eaten steak but within the last 6 monthes it seem that any kind of meat make me sick and it always hits as soon as 5 minutes to 20 minutes after? what is wrong next to me? Yah need more fiber and veggies. I have to switch myself. It works. Any meat used to travel through in a issue of minutes. I make sure to bring some potatoes, greens and lots of bread.
I do the chex mix for fiber.
