Made with 100% pure sunflower oil. 0 grams trans fat. Like a ray of golden sunshine, Lays Brand Wavy 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 regular potato chips. (Regular potato chips contain 3 g saturated fat per 1 oz serving and 10 g total fat. Lay's brand Wavy Potato Chips made with 100% pure sunflower oil contain 1 g saturated fat per 1 oz serving and 10 g total fat. Total fat intake should be between 20-35% of total calories.) 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.
