Popular is not always usually what is. As much as possible, make sure that your bread is made with whole-wheat flour, not just wheat flour. Also, look for the other chemicals that are in you bread? A report from the Environmental Working Group finds that the compound, azodicarbonamide (same chemical is yoga mats), is found in close to 500 food products, from Pillsbury Dinner Rolls to Little Debbie products to Wonder Bread. My favorite, and usually only bread I eat, is Ezekiel 4:9 made with sprouted grains. bread:http://www.foodforlife.com/product/breads/ezekiel-49-low-sodium-sprouted-whole-grain-bread
Oh, and processed meats.... that is another post, in short.... they are terrible for you.
