A sandwich wrap can have crap in it, like any other prepared food – hydrogenated oils, preservatives, artificial colors.  Skip the so-called spinach wraps, they’re often just seasoned with spinach powder for color.  But if you pick the right ones, you can lose weight and boost antioxidants with whole grain corn, wheat, and brown rice tortillas, wraps, and pitas instead of bread.  I’d go with two 6-inchers over one big one – it stays neater, it’s the same calorie count, but seems like more food.  Two brands at the supermarket stand out: La Tortilla Factory (also called Sonoma) and Weight Watchers, and don’t fall for the multigrain label, go for the WHOLE grain.  It’s so easy to fill them with mostly lettuce, cabbage, and sprouts with just a touch of chicken, cheese, and sauce for protein and taste.  In restaurants, a sandwich can sometimes be less calories than a wrap, as in Chick-fil-a’s chargrilled chicken on a whole wheat bun versus the wrap, but both are healthy choices without sauce.  Ruby Tuesday’s has a chicken wrap on a whole wheat tortilla and PF Chang really carbs down with a veggie lettuce wrap.
