I recall being surprised, shocked even, when I read that MacDonald's French fries were dusted/coated with beef powder. This was at least a decade ago and perhaps their preparation ingredients have changed. It must be almost that long since I visited this establishment. (I'm not making a value judgement; as you may know 'to each his/her own' is my motto.) There was an item in the local newspaper about a man who, as a practising Hindu, didn't eat meat. He was distressed to discover that without meaning to he had been consuming it. Something so unusual should have been posted on the menu board for the elucidation of vegetarians and vegans as well as those with religious requirements.
I've recently read similar information about pork. For some reason known only to them, food processors/manufacturers include pork flavouring, tinctures, bits of it in many unexpected food items like cookies, cereal and sour cream. This article might be an eye-opener to you.
Manufacturers know that many consumers don't like to buy products where the main ingredient is sugar. The way around this is to use use a combination of sucrose, high-fructose corn syrup, corn syrup solids, brown sugar, dextrose and other sugar ingredients to make sure none of them are present in large enough quantities to attain a top position on the ingredients list.
Remember that ingredients are listed on products in order of their proportion in the product. This means the first 3 ingredients matter far more than anything else. The top 3 ingredients are what you're primarily eating. Don't be fooled by fancy-sounding herbs or other ingredients that appear very far down the list. Some food manufacturer that includes pomegranates towards the end of the list is probably just using it as a marketing gimmick on the label. The actual amount of pomegranates in the product is likely miniscule.
If the ingredients list contains long, chemical-sounding words that you can't pronounce, maybe google the word(s) so you'll know what you're eating.
Think about your pets, too. I was taken aback to discover that In 2004 the American Veterinary Medical Association undertook a 20 year study involving thousands of cats, including 3,470 hyperthyroid cats. While the study found that feline hyperthyroidism was definitely more often found in older cats, there also was evidence that BPA was a factor. BPA, Bisphenol A, is used to line the inside of many cat food cans.
Knowledge is power. Don't feel helpless! I tend to try to make most of the food I eat from whole ingredients. Works for me.
