I remember when butter would kill you because “animal fat” and margarine would make you live forever because “made from vegetable oils”.
And I remember when sugar would kill you dead but high fructose syrup would make you live forever because it came from fruit.
I’m old enough to remember the bran muffin craze. Everybody was eating them. And then running to the toilet a few hours later.
I remember that oleo time. Glad sanity finally ruled!
