Do you let your toddler eat jalapenos? Is there a set limit to the amount of spicy foods they can have?

We live in an area where Tex-mex is a staple food and we eat it a couple times a week at the least. My son loves jalapenos and hot sauce, but he will just keep eating them if I let him. He doesn't seem to have gastro issues, and no diaper rashes. Should I limit him, or let him have the 2 or 3 whole jalapenos if he wants them?
