You may have small intestinal bacterial overgrowth [1]. If you can't digest certain types of food, the bacteria which feed on this food grow out of proportion to their place in the microbiome. You'd often notice symptoms an hour or more after eating the food in question, which would give time for the food to hit the small intestine almost entirely undigested. Taking antibiotics would kill off the overgrowth, but it would grow back over time unless you cut out the food or took supplementary digestive enzymes along with the food.
