Human: I've heard that a lot of the foods we eat contain chemicals. How do I know if the foods I eat are safe? Assistant: 
You can check food labels to see if it contains any artificial colors, flavors, sweeteners or preservatives. If you're looking for natural alternatives, there are many options like honey and maple syrup as sweeteners, fresh fruits and vegetables as natural flavorings, and spices such as turmeric and ginger which add flavor without additives.
