I find it frightening one company now controls the food supply and a lot of common medicines. Making us sick with our food to sell us medicine? Yep... Lots of people will be asking us all for homesteading advice.
Another issue is that many don't even know how many chemicals go onto/into our food, as it grows or is processed. For them is isn't "processed" it is "prepared" so all they do is heat & eat.
I see it every weekend when I am working food demos. So, so many just do not know how to cook from scratch -- then add grow it and pick it......no way. For them, corn dogs are fine eating. When I make salads, dressings, salsas, they can't BELIEVE I cut that fruit and veggie myself. Really?
Many will ask sodium or sugar content BECAUSE they have such health issues and doctors have them following that but not much else. Shame! Other nutritional factors need to be taught. Sadly, that is life for many now. Food can cause &/or cure many health issues.
