Organic Pasta (Organic Wheat Flour), Whey, Cultured Cream, Nonfat Milk, Salt, Butter (Pasteurized Cream, Salt), Dried Cheddar Cheese (Cultured Pasteurized Milk, Salt, Non-Animal Enzymes), Corn Starch, Citric Acid, Annatto Extract (For Color), Lactic Acid, Sunflower Lecithin, Sodium Phosphate, Silicon Dioxide (For Anticaking).
None of this bothers me, but the declaration "No artificial flavors, synthetic colors, or synthetic preservatives" seems out of place with those last six ingredients. It's technically true, but that's a context where you sorta want more than merely "technically true".
I don't think any of them are harmful... but then, neither are the artificial and synthetic versions they're replacing. They don't strike me as all that different from the Kraft ones:
enriched macaroni (wheat flour, durum flour, niacin, ferrous sulfate [iron], thiamin mononitrate [vitamin b1], riboflavin [vitamin b2], folic acid); cheese sauce mix (whey, milkfat, milk protein concentrate, salt, sodium triphosphate, contains less than 2% of citric acid, lactic acid, sodium phosphate, calcium phosphate, with paprika, turmeric, and annatto added for color, enzymes, cheese culture).
