People in India have been using mustard seed oil and rapeseed oil for many generations and nobody seems to get cardiac muscle damage. AFAIK there is zero evidence of this in humans. Just because it happens in rats, the regulators got scared and did this to us. I don't think the "low acid" makes any significant difference.
So if you take rapeseeds, not GM modified to be "roundup ready" but the original ones, not cross-bred to be low-acid, cold press extract the oil, and don't chemically remove the taste, I admit that would probably be a healthier oil. But nobody around here sells it.
