May I ask the reason for your interest in a replacement? If it has to do
with cholesterol, there may be good news. A close friend is a research
nutritionist who changed my mind about the issue based on resent
experiments. My count dropped almost a hundred points (265 - 180) by
gedding rid of trans fatty acids. I reintroduced eggs to between 3 and 5 a
week with no change. It's the fat.
