There are lots of foods that you can develop a sensitivity to if you eat them more than a couple times per week. So it might not even be a permanent intolerance, but rather something that's more transient. E.g. supposedly if you eat wine cap mushrooms more than twice in a week then you'll be throwing up everywhere, but then you'll be fine again to eat them a week later.
