High quality oils and fats are really important, as well. The vegetable oils in everything these days is not made for human consumption. These were seen as fuel for the diesel engine at the time they were developed, and do not bode well for the human body. Wtf is a canola anyway? Actually, it's derived from a plant that is toxic to humans! Nice work, food industry!
There is trash everywhere, the healthiest way to live is away from the city in nature, growing your own food and killing your own chickens.
