Lay's is a brand of potato chips founded in 1932. It was the first potato chip brand advertised on television in 1944. Lay's is now owned by PepsiCo as part of their Frito-Lay division. People prefer Lay's chips for their variety of flavors and marketing. However, potato chips are generally considered an unhealthy snack due to their high fat and salt content. While Lay's does not specify the type of oil used, potato chips provide some nutrients like potassium and vitamin C.
