Brookshire Grocery operates 152 Brookshire and Super 1 Foods stores throughout Texas, Louisiana, Mississippi and Arkansas as well as Ole Foods in Plano, TX. In addition, the company's manufacturing division, SouthWest Foods, recently introduced LeCarb dairy products and YoCarb desserts for diabetics and low-carbohydrate dieters.
