The jury is still out on the seeds and nuts debate.
I have found that nuts are fine as long as there are bsufficient fluids and they (the nuts) are thoroughly chewed. They seem more intestinally friendly and they are fiber rich and nutritious.
Seeds, I don't like taking such risks, especially with the very hard seeds such as sesame and blackberry. In also avoid eggplant. (never cared for strawberries). Tomato and cucumber seeds are somewhat softer, but, still it seems best to avoid.
My late aunt used to slice a banana open and cut out the seeds. Of course she had surgery more than once for her diverticulitis woes. I've eaten blueberry and banana seeds with nio apparent issues.
Best to discuss with the medical professionals.
