Made with 100% pure sunflower oil. Same great taste. 0 Grams trans fat. Like a ray of golden sunshine, Lay's brand Potato Chips have a special way of making everyone smile. From the anticipation of the crisp, savory taste to the simplicity of the ingredients - we use only our best potatoes, 100% pure sunflower oil, and salt, you'll agree they're simply irresistible! And because our potato chips are cooked in pure sunflower oil, they have at least 50% less saturated fat than our regular potato chips. That's another reason to smile! Great News! The 2005 Dietary Guidelines recommend that most of the fats you eat be mono and polyunsaturated fats. Sunflower oil is 90% mono and polyunsaturated fats and has 0 grams of trans fat.
