Carrots do not contain vitamin D. While they are a rich source of vitamins and dietary fiber, carrots will not contribute to vitamin D levels. Generally, vitamin D is not found in fruits and vegetables, with the exception of some mushrooms. Exposing commonly consumed mushroom varieties to UV radiation produces vitamin D, which remains with storage and cooking. This may be a practical option for vegetarians, vegans, and other dietary patterns as mushrooms are a versatile and popular food (1).
