This is all NONSENSE.......
I'm in the food packaging business and can relay another side of the story for which I will be branded as a corporate lacky.
Being part of the packaging industry I can chart different movements and their effect on the consumer. First it was recycle...then it was recycle percentage, when both of those died out, the buzz word now is sustainability.
In the food industry it was labels. First to ID calories then trans & saturated fats. Now organic is the BIG word for which I can personally attest is noting more than marketing used to separate the consumer from their money. I suggest people read Micheal Pollen's Omnivores Dilemma as a starting point to understand the cornerstone of our food sources and monoculture food production. This book is interesting in that it does not judge the system but tells it like it is. Farmers vs. distributors. Organic vs. regular food.

What I've come to learn is there is 330 million people in the US. Less than 1.4 percent of our population produces food, and frees up the other 98.6% to do other stuff. You don't get something for nothing and when the best a producer can sell his product is .50 per lb, a few things have to happen. Either he gets efficient or capitalization rolls in and does it for him. Next time you buy a bag of salad for less than a head of lettuce, thank the captains of industry because 97 percent of you don't have time or the knowledge to grow it yourself.
What I object to is people organizing their lives around a concept that has no merit, other than to make you feel good. Get you to focus on phrase (anti oxidant, omega 3,) instead of what I consider the real issue.
There is no corporate conspiracy other than to value add foods to make a profit. And considering our population grows at 3%....the food industry must find ways to get you to buy more food. They have an army of experts marketing genius that can overwhelm any attempt of resisting their message, EXCEPT for you saying no.
Your body does not care if a fat-sugar-carb calorie goes into your pie hole, it will process it. What does not get used is converted to fat. One pound of fat is 3500 calories and is enough energy to sustain you for two days. Think of that.....if your 40 pounds overweight.....80 days of fuel.
But there's a cost and carrying extra fuel for long periods dings your health. So while the industry has you worried about a non issue, calories creep up because people have made a million excuses as to why they will not exercise. And if they start exercising its usually not efficient enough to produce results. Thus the weight cycle repeats over and over.
Off the soap box for now.
