When asked if carrots are good for your eyes, some might reply, "Have you ever seen a rabbit wearing glasses?" The same sentiment might apply to dogs that are fed carrots as a regular part of their diets. Carrots are well known for promoting good vision, and in both humans and dogs, they nourish the optic nerve and promote good visual health.
In addition to their visual benefits, carrots are also a rich source of the provitamin beta carotene, a nutrient that can be converted into vitamin A. Beta carotenes are powerful antioxidants that can help to prevent cancer. Carrots also contain vitamin C, a nutrient that helps produce collagen in bones, muscle, cartilage and blood vessels so that iron can be absorbed by the body.
In addition to vitamins A and C, carrots are sources of vitamins D, E, K, riboflavin, niacin, calcium, potassium, phosphorous, sodium, magnesium and iron. These important vitamins and nutrients support the immune system and digestion.
