If you've seen parsnips at the farmers market, you may have felt a little bit perplexed. Parsnips look like bleached, overgrown carrots, but they provide so much more than meets the eye.

Despite a lack of vibrant color, parsnips have a lot to offer. These root vegetables are tasty, easy to prepare, and brimming with health-boosting nutrients. If you aren’t eating parsnips, perhaps it’s time to consider adding them to your shopping list.

Health Benefits

Parsnips have a lot to offer. But they are often underrated for their health-promoting nutrients. Here are some of the potential health benefits of parsnips.

May Reduce Risk of Breast Cancer

Adequate fiber intake during early life (through adolescence and young adulthood) has been shown to significantly lower breast cancer risk later in life. Parsnips are a great way to increase fiber your intake, especially considering that most Americans routinely fall short on this essential nutrient.

Beyond fiber, parsnips provide antioxidant vitamins, like vitamin C and vitamin E. These vitamins help the body scavenge free radicals and reduce DNA damage that may lead to cancer down the road.

Promotes Strong Bones

Parsnips provide a decent amount of magnesium and calcium—two crucial minerals for bone development. A cup of sliced parsnips has over 45 milligrams of magnesium.

With the daily recommended intake for most adults at 320 to 420 milligrams, parsnips easily provide more than 10% of magnesium needs. Given magnesium's role in the structural formation of bone, parsnips are a wise choice for bone health.

Supports Heart Health

Parsnips have several nutrients that are beneficial for heart health. The fiber in parsnips keeps blood levels of cholesterol down. Plus, parsnips are especially high in potassium, which is known to lower blood pressure.

Additionally, parsnips provide vitamin C, a powerful antioxidant, and folate, which significantly reduces the risk of stroke. Along with most other vegetables, parsnips are a great way to protect your heart.

Prevents Diverticular Disease

Getting enough fiber is essential for intestinal health. With parsnips providing almost 6 grams per cup, you can get closer to the daily recommended minimum of 20 to 30 grams per day with just one serving.

Consuming adequate amounts of insoluble fiber from foods like parsnips can reduce the risk of diverticular disease by up to 40%. Parsnips also can help you ward off this painful condition as you age.

Enables Wound Healing

Without enough vitamin C, our bodies are unable to synthesize collagen, a key structural component of skin. Vitamin C's antioxidant effects play an essential role in wound healing, along with its ability to act as a precursor to collagen.

Our bodies are unable to produce vitamin C, but luckily, parsnips are a wonderful source. With 20 milligrams of vitamin C per cup, parsnips contribute to the daily goal of 75 to 90 milligrams per day.

Allergies

Parsnips are associated with mugwort weed allergies in a cross-reactivity phenomenon known as oral allergy syndrome. Cooking parsnips, rather than eating them raw, can reduce the likelihood of this issue.

A food allergy to parsnips may also cause hives or allergic contact dermatitis. Itching, burning skin and/or swelling of the mouth, lips, and tongue are all possible symptoms. If you suspect a parsnip allergy, contact your healthcare provider.

Adverse Effects

For most people, the high potassium content of parsnips is a benefit. However, for people with kidney disease, parsnips can lead to a dangerous build-up of potassium in the blood. If you have poor kidney function, meet with a registered dietitian to discuss how parsnips should fit into your meal plan.

Also, if you aren't used to eating a lot of fiber, a sudden increase in your parsnip intake may be tough on your digestive system. To reduce potential discomfort, increase your intake of high-fiber foods gradually to give your body enough time to adjust.

Varieties

There are multiple varieties of parsnips that vary in their ability to resist various diseases. Some varieties of parsnips grow better in certain types of soil and come in slightly different sizes and shapes. Examples of parsnip varieties include Skirret, Panache, Harris Model, Tender and True, Gladiator, Andover, and All American.

When It's Best

Parsnips are best in the early spring, but they can also be found in the fall. During cold winter months, parsnips develop in sweetness and flavor. Smaller parsnips are more concentrated with antioxidants, so choose the little ones for maximum nutrition.

Storage and Food Safety

Store parsnips in the refrigerator in the vegetable crisper or in a plastic bag to prevent them from drying out. Parsnips will keep in the refrigerator for 2 to 6 months.

Prior to use, scrub parsnips with a vegetable brush and wash thoroughly under running water. Chop off the top, end, and peel.

How to Prepare

While it is less common, parsnips may be eaten raw. They are earthier and not as sweet as when cooked. For best results, slice or shred as thinly as possible. Pair raw parsnips with hardy leafy greens or other raw root veggies (such as carrots or radishes) in a salad or slaw. 

To help balance out the flavor of raw parsnips, season with fresh citrus juices, a sprinkle of sea salt, and a drizzle of fruity extra virgin olive oil. Toss into a salad with raisins or pomegranate seeds and finish off with a sprinkle of salty cheese or a few crunchy nuts.

You also can roast them to bring out their sweetness or boil them and use as a substitute for mashed potatoes. Add parsnips to soups and stews for added nutrition and flavor.
