Not a huge fan, but as a convenience I would occasionally buy prepared frozen squash. About 3 years ago, I noticed that it became an extreme upper GI issue for me (I have major esophageal reflux problem). I switched from the brand I'd previously used to a generic. Same problem. So I simply gave up. For whatever reason, about 6 months ago, I bought a butternut squash, steamed it myself. Easy to do, tastes great, and absolutely no acid reflux problem. My guess is that with the prepared stuff the manufacturers starting saving on labor costs by cooking the whole damned thing--seeds & peel included and then mashing the result. The higher cellulose content in seeds & peel were probably the culprit. Anyone else had an issue with this?
