Can red beets daily for 3 months cause IBS ?

I’ve been eating red beets daily for the past 3 1/2 months never had an issue till the past two weeks, started having almost daily IBS or diarrhea some days worse than other I wash the beets cut them in squares wrapped them in foil and cook them in the oven and have been eating them almost daily. This has lowered my blood pressure, which is what I was trying to do but not sure if it’s causing my IBS or if it’s something else going on. Anyone else have similar experience ?
