There is another part to the analogy: we've all woken up to the fact that corporations re-engineered the food supply after World War II. They were hacking the human body. I think I didn't get this say in the year 2000, but I really get it now. Think about what your grandparents ate vs. what your parents ate (assuming you grew up in the U.S. and are in the 20's-30's age range. Anecdotally the effect seems to have been…
Could you expand on what you feel the goal of their hacking was/is?
I believe one of their goals was to lower testosterone in general population, to make for a meeker and more easily controlled population. This probably wasn't a 'fully evil' goal, since the horrors of WW2 were recent, and some of them thought that they could prevent that from happening again by engineering a less aggressive population.
From the onset of 20th century at least, it was known that testosterone is responsible for 'manly' characteristics (aggressiveness etc); in 1935 it was synthesized from cholesterol by Lavoslav Ruzicka. So, by the end of WW2 it was already well known that a) testosterone is what makes people aggressive and b) body needs cholesterol to synthezise testosterone. With this information in hand, it's easy to conclude that to get a less aggressive population, one should make them eat less saturated fat/cholesterol.
Enter Ancel Keys, a military-related dietologist (he created the ww2 K-rations, for example). Before mid 1950s, he was making rational scientific research into good/bad foods, and even published some material about the negative health effects of 'grain' ie carbs. But by the mid 1950s he made a full 180 and started attacking saturated fats and cholesterol as the cause of (especially heart-related) health problems. He started using bad science (selectively choosing countries for study to confirm his claim that it's high fat and not high carb diet that causes health issues), and using his pull to silence everyone claiming otherwise.
In 1960s/1970s he was joined by the Big Agro/Food who poured a lot of money into continued shifting of the blame from carbs onto fat, including silencing and ostracizing scientists and studies who dared to claim otherwise; this is the 'conspiracy' that we are familiar with, but I believe it started even earlier, with Ancel Keys, military, and 'powers that be'.
