I grew up on a rather large farm/ranch operation until I was 16. And I have my own ranch out in the middle of nevada.
1. Regardless if you eat poultry or prefer cow, you cannot possibly believe the quantity of antibiotics that are regularly fed/injected into the food that poultry eat (including the hormones mixed in poultry mash they eat in the first two/three weeks of feeding and burns out their sex glands so they get really, really big).
2. Even happy free-range cattle that we let run around in Nevada are eventually sent off to a feed lot where they live in the filthiest conditions possible, shot up with even more antibiotics and anti parasite drugs. And then they remain in feed lots where they eat a corn-based feed, often mixed with chicken shit full of undigested grain from an egg-laying operation, and a dash of growth hormones that are illegal for weight lifters to use.
And that's just your meat. Want cleaner meat? Eat lamb, rabbit, goat or farm-raised trout. Trout Chow is relatively chemical/hormone free, because trout can't process lots of chemicals.
As for your vegetables? Don't get me started.
But anyone who eats processed foods might as well as also smoke a pack if red dog Pall Malls twice a day. Sugar, by itself, is not so bad. A packet or teaspoon or sugar contains 16 empty calories that can make you feel pretty good when mixed in coffee or tea with a bit of milk in the morning. But pancakes or waffles covered in fake maple syrup are disgusting. The corn industry is currently trying to tell everyone that corn syrup isn't as bad as the regular disaccharide table sugar. Wrong. Corn syrup is to table sugar as heroin is to tea made from dried opium leaves. It's sweeter and they use more of it in soft drinks, cookies, Twinkies, etc. Avoid it at all cost. And to raise corn, it's common to treat millions of acres with one of 12 different herbicides that prevents anything except grains from growing in the same soil for more than 10 years. Just check out atrazine, the most common herbicide that DOES NOT decay or degrade into less harmful molecules. But it does, eventually, make it into all aquifers.
It's amazing that any of us are alive in the USA, Canada, or Mexico.
