The food pyramid that was beat into the brains of nearly every Gen X/millennial and hung on the wall of every public school cafeteria in America, is basically the same recipe we use on farms to fatten animals for slaughter.
Not surprisingly, these generations are rife with obesity, autoimmune disorders, gut health problems, diabetes, you name it. Big Food makes us sick and Big Pharma gets everyone hooked on predictions to treat the symptoms. What a cycle!
When science evangelists act like science is absolute, unbiased, and infallible, keep in mind how much mainstream food science has doubled down on falsehoods, flip flopped, evolved, etc in the last 30-40 years.
