Starbucks offers a variety of food and beverage products, including coffee drinks, tea, smoothies, and food items. However, some of their products contain additives and artificial ingredients that some people may want to avoid. Starbucks publishes guidelines for their food and beverage suppliers, which include requirements for raw materials, processing aids, and finished products. Suppliers must also identify any hazardous materials sold to Starbucks and supply a Material Safety Data Sheet. Starbucks has made efforts to expand its menu to include more plant-based options and to accommodate dietary preferences, such as gluten-free, low-fat, and low-calorie options. Additionally, Starbucks utilizes recycled coffee grounds on their tables and materials low in harmful chemicals for adhesives, paints, coating, and sealants to position their brand as environmentally friendly.
