The level of evidence about eggs was spurious at best even in the 80ies. As with a lot of food science preliminary studies and ideas get overblown in media.

But at least the scientists I know would wait for the level of evidence to be high.

But as policies would be made by politicians I doubt it would work without populistic influences.

Yes, I remember the endless LDL and HDL cholesterol public health debates in the 1980s, especially arounds chicken eggs. When I was older, I learned that the Japanese consume a phenomenal amount of eggs per capita -- over 300 per year(!). (Raw egg over rice is a common breakfast dish.) Yet, the Japanese have much lower incidence of heart disease (per capita) than the United States. The reasons are multi-factor -- not all of which are understood.
