I'm convinced that it's all part of the bad plan. I have an old copy of Adele Davis' "Let's Eat Right to Keep Fit". In it, she talks about experiments that the US Gov was doing on conscientious objectors during WW2, regarding things like B Vitamin intake. It's been known for ~80 years that B vitamin deficiencies cause things like depression, fatigue, insomnia, adult-onset schizophrenia, hair loss etc etc.

Basically, if you look at all the health/mental complaints that people have today, a large part of it can be traced back to lacking these vitamins (and certain minerals like magnesium). If we take the 40000 ft. view, it appears as if the governments of Western nations colluded with the corporations to produce the lowest value foods possible, while decrying or trying to ban things that are actually healthy like butter, meat and milk. It's a win/win situation - the corporations make $$$ and the governments get a populous that is dumbed down, slowed down and sick.
