I've decided not to eat another Whataburger, ever.
Check out the ingredients just in a Whataburger bun: Large Bun: Unbleached enriched flour (wheat flour, malted barley flour, niacin, reduced iron, thiamin mononitrate, riboflavin, folic acid), water, high fructose corn syrup, soybean oil, contains 2% or less of each of the following: yeast, wheat gluten, salt, dough conditioners (contains one or more of the following: sodium stearoyl lactylate, calcium stearoyl lactylate, monoglycerides, mono- and diglycerides, distilled monoglycerides, calcium peroxide, calcium iodate, datem, ethoxylated mono- and diglycerides, enzymes, ascorbic acid), calcium sulfate, calcium carbonate, ammonium sulfate, sorbic acid, soy flour, monocalcium phosphate, soy lecithin, and calcium propionate (to retard spoilage). May also contain grain vinegar, cornstarch, citric acid, and potassium iodate, and calcium phosphate.
Then there's the Bun Oil: Soybean oil, soy lecithin, natural and artificial flavor, TBHQ added to protect flavor, beta carotene (color), dimethylpolysiloxane, an anti-foaming agent added.
