Although carrots are available throughout the year, locally grown carrots are in season in the summer and fall when they are the freshest and most flavourful. This vegetable are related to parsnips, fennel, parsley, anise, caraway, cumin and dill. Carrots can be as small as two inches or as long as three feet, ranging in diameter from one-half of an inch to over two inches. While we usually associate carrots with the color orange, carrots can actually be found in a host of other colours including white, yellow, red, or purple.
Carrots are perhaps best known for their rich supply of the antioxidant nutrient that was actually named for them: beta-carotene. However, these delicious root vegetables are the source not only of beta-carotene, but also of a wide variety of antioxidants and other health-supporting nutrients. The areas of antioxidant benefits, cardiovascular benefits, and anti-cancer benefits are the best-researched areas of health research with respect to dietary intake of carrots. Given their antioxidant richness, it’s not surprising to find numerous research studies documenting the cardiovascular benefits of carrots.
Our cardiovascular system needs constant protection from antioxidant damage. This is particularly true of our arteries, which are responsible for carrying highly oxygenated blood. While you might expect to find a large number of human research studies documenting the benefits of carrot intake for eye health, there are relatively few studies in this area. Most studies about carotenoids and eye health have focused on carotenoid levels in the bloodstream and the activities of the carotenoids themselves, rather than the food origins of carotenoids. Still, we have found some smaller scale human studies that show clear benefits of carrot intake for eye health.
The anti-cancer benefits of carrot have been best researched in the area of colon cancer. Some of this research has involved actual intake of carrot juice by human participants, and other research has involved the study of human cancer cells types in the lab. While much more research is needed in this area, the study results to date have been encouraging.
