I think it might depend on the type of IBS you have. Just like Elizabeth, I tend to stay away from seeds since they trigger symptoms for me, but I also have IBS-D.
I did a quick search on our website and found that most articles recommending seeds are talking about IBS-C. Here are some examples:

https://irritablebowelsyndrome.net/food/pregnancy-nutrition-fodmap (this article is about pregnancy, but it does recommend flax seeds to help with constipation).
What type of IBS do you have?
