You’ll notice as well those graphs start when they began to nudge good and hard for nationalized healthcare.
You would never get a fairly healthy fit population to agree to such a thing. You would get a fat unhealthy sickly population to agree to it however...
Just sayin’.
And what has happened to pharma profits over the time since carbs and ‘healthy whole grains’ (that are whole grains but hardly healthy) became the base of the food pyramid?
It not only has to do with food choice, but what manufacturers did: they lowered the fat ( "low-fat" salad dressing, mayo, cookies, etc.) and then raised the carbs (since much of it became unpalatable).
