Carrots and Carotenoid Compounds

Did your mother nag you when you were a kid to eat your vegetables, especially carrots? Turns out mom was right, carrots have several health benefits.

Here are some carrot nutrition facts to prove mom knew best.

The Office of Dietary Supplements at the National Institutes of Health claims that foods rich in Vitamin A, like carrots, can help with the following:

• ·       Bone growth
• ·       Cell differentiation (cells know which tissue to become a part of, like blood, brain, lungs, etc…)
• ·       Immune system regulation (white blood cell production to fight off viruses and bad bacteria)
• ·       Surface lining integrity (eyes, lungs, intestines and urinary tracts)

Carrots contain antioxidants called, appropriately, carotenoids, which are natural red, yellow, or, of course, orange-colored compounds found in plants. Beta-carotene, one of approximately 500 types of carotenoids, is the well-known antioxidant component in carrots.

All carotenoids are important, as a diet rich in them may reduce the risk of developing several types of cancers, including bladder, cervix, colon prostate, larynx and esophageal.

Several studies (such as this one focusing on lung cancer, published in the American Journal of Epidemiology) have proven that a diet high in carotenoids leads to a reduced risk of cancer.

In the book ‘150 Healthiest Foods on Earth,’ author Johnny Bowden, Ph.D. in nutrition, dedicates an entire chapter on carrots. He says in the book that although carrots are best-known for their beta-carotene, they also contain alpha-carotene, which might be equally as protective against diseases, if not more so, than beta-carotene.

One study by Japanese biochemists suggested that alpha-carotene was ten times more powerful than beta-carotene in inhibiting tumor growth.

Alpha- and beta-carotene convert in the body to Vitamin A, hence the reason for a single serving of carrot’s 200 percent suggested Daily Value (DV) of Vitamin A.

Aren’t carrots good for the eyes?
The micronutrients in carrots that promote optimal vision are two other of the five major carotenoids: lutein and zeaxanthin, which are the only carotenoids found in the retina. They may help in the prevention of macular degeneration and cataracts, according to one study in the Archives of Opthamology.

The aforementioned Dr. Bowden’s ode to carrots also mentions that carrots contain a purple pigment—rhodopsin—which helps with vision in dim lighting.

Nutrition data for carrots
Eating just three medium-sized carrots contain:

·       6-8 mg of calcium

·       58 mg of potassium

·       Approximately 7 percent DV of magnesium, phosphorous and Vitamin C

·       30,000 International Units (IUs) of Vitamin A

·       15,000 IUs of beta-carotene

·       6,000 IUs of alpha-carotene

·       5 grams of fiber

But aren’t carrots high in sugar?
Nutrition data from the FDA says that one-half cup of baby carrots contains three grams of sugar. One gram of carbohydrates (sugar) equals four calories, thus a single serving of carrots has 12 calories of sugar out of the 30 total calories.

So, should you ditch carrots?

No, suggests Diane Madrigal, a San Diego-based clinical nutritionist. “Carrots are extremely healthy whether or not you have diabetes, because in its whole nutritious form, you’re getting all the nutrients and fiber, which will slow down the release of sugar,” she says.

But Madrigal says that because Vitamin A, which carrots are loaded with, is a fat-soluble vitamin, to get the most out of carotenoids, eat them with a little fat.

“Hummus, guacamole, tzatziki and babaganoush are excellent dips for carrots,” says Madrigal.

What if I start turning yellow from eating too many carrots? Is that bad?
Beta-carotene may accumulate in your skin if you eat too many carrots, coating it with a yellowish tint. This discoloration, scientifically referred to as ‘carotenemia,’ is usually harmless. If your skin changes color, cut down on your dietary beta-carotene and discontinue any supplements that contain it. The whites of your eyes, however, should not turn yellow. If so, seek immediate medical help.
