Pretty much every meat from a deli is processed too.
I'd say fries (deep fried food) are much worse for you than the burgers. Maybe a salad with a 100% fat dressing (with more calaries than a Big Mac) would clear my conscious.
Nutrition is a complicated game.
Fat free means they dump a lot of sugar into it. Sugar is a simple carbohydrate and is broken down and stored as fat much easier by your body than actual fat or complex carbohydrates. Protein is the hardest to break down. I.E, the basis behind Atkins and the Zone diet plans.
You might as well have the rich fat dressings because they are actually better for you.
If you take the extraordinary steps to eliminate all refined sugar from your diet you will be healthier. Its damn near impossible to do unless you can cook.
I eat meat and veggies and complex carbs and I have never felt better.
Oh, and the best Mayonnaise is Saur and Dukes, which is made by Saur. Helmans is close third.
Last little tidbit. A Aioli is a supped up mayonnaise.
I like to take helmans and add fresh pressed garlic,finely crushed rosemary, a little vinegar, lemon juice, a squirt of hot sauce ( homemade) and fresh finely chopped italian parcley. Now that is a great MAYO.......err...........Aioli!
