Healthier or not?

The health gurus of the 1970s are getting a poke in the eye from the current gurus and influenzers. Going from beet tallow to cooking oils was a mistake, they are saying.
    Seed oils are industrial products whereas tallow is natural and has been used safely for thousands of years. To complicate things, dieticians are saying that neither of the above is a healthy product and they need to be used sparingly.
