Do you see celery as nothing more than a crunchy accompaniment to your wings-and-blue-cheese dish, or just one of the raw veggies in your crudités tray? It doesn’t get enough love, especially considering all its health benefits.

This humble green stalk is rich in nutrients that can support various health concerns. From gut health to diabetes management, it can be a helpful addition to your diet. And like cucumbers, celery has a lot of water content. In fact, it’s made up of 95 percent water, so it may also be an excellent way to keep your fluids up.

Celery is touted for its beneficial effects on lowering glucose, but there is not enough research to confirm this. Researchers believe that the phytochemicals in celery may help increase insulin sensitivity and reduce inflammation, both of which are vital factors in maintaining healthy blood sugar levels. In one study, participants who ate two stalks of celery per day for four weeks saw significant improvements in their blood sugar control. 

Celery (Apium graveolens), an herbaceous plant of the parsley family (Apiaceae), also has a long history of use as a medicinal herb in practices like Ayurveda. And since it may have the potential to help with everything from blood pressure and cholesterol to blood sugar levels, it’s a good idea to learn more about it. Read on to see why you should include it in your diet.

Is There Sugar in Celery?

Whole foods usually contain natural sugars, which don’t have the same adverse effects on your health as the added sugar in processed food. Fruits contain natural sugar but they also contain fiber, micronutrients, antioxidants, and water. Most processed foods with added sugar are low in fiber and not nutrient-dense.

Although most fruits and vegetables contain naturally-occurring sugars like sucrose, fructose, and glucose, not all are created equal. For example, tamarind and jackfruit are higher in sugar than mushrooms and tomatoes.

Where does celery stand on the sugar scale? Celery is a vegetable that is low in both calories and sugar content and high in fiber and water content. It’s why it’s often recommended as a snack for people looking to lose weight or manage type 2 diabetes.

One stalk of celery contains less than a gram of sugar, three percent of your daily fiber intake needs, only six calories, and many other vital nutrients. So, it can help regulate blood sugar levels when it’s part of a balanced diet.

The Benefits of Celery

Celery may not be as flashy as other vegetables, but it’s more than just a side! It’s a good source of dietary fiber, potassium, and vitamin C and has anti-inflammatory properties that can help fight off disease. So, consider incorporating the vegetable into more mains to reap its benefits. Here are some of its primary health benefits:

It Can Help Prevent Heart Disease

Celery is a powerhouse of nutritional value. It's a low-calorie, high-fiber option and a good source of potassium, vitamin K, and folate. It’s also known for its ability to reduce blood pressure levels and improve heart health overall.

It Has Digestive Health Benefits

Celery is also known for its digestive health benefits. Some of the nutrients found in celery include fiber, potassium, and vitamin C. Celery is a good source of antioxidants, which can help protect the body against free radicals.

Additionally, celery contains natural compounds that can help support digestive health and may reduce your risk of stomach ulcers (although most of the research has been done on rats). Consuming celery may also improve gut function and reduce inflammation. 

It Can Strengthen Your Bones

Did you know that celery is an excellent food for bone health? It contains high levels of magnesium, flavonoids, and Vitamin K, which are beneficial for bone health.

You need potassium to maintain bone mineral density, which is something else celery has to offer. It’s safe to say adding celery to a balanced diet can help keep your bones strong and healthy as you age. 

It Helps You Stay Hydrated

Think of celery as nature's sports drink. This fibrous vegetable is mostly water (95 percent, as mentioned above), but that’s not the only reason it helps with hydration. It also contains essential electrolytes like sodium and potassium, making it an excellent option for pre-workout hydration. And the fiber in celery can help regulate blood sugar levels and promote gut health.

It Has Many Essential Vitamins

If you're looking for ways to increase your daily intake of vitamins, add some celery to your diet. Celery is a good source of vitamin A and vitamin C, which are essential nutrients that our bodies need to function correctly. In addition, celery is a low-calorie food, making it a healthy choice for those trying to lose weight or maintain their current weight. 

It Has Anti-inflammatory Properties

One of the main benefits of celery is its anti-inflammatory properties. Inflammation is a major factor in many chronic diseases, so by consuming foods that have anti-inflammatory effects, you can help to prevent these diseases. Celery is rich in antioxidants and phytochemicals, both effective at reducing inflammation in the body.

It Helps Regulate Blood Pressure

As we mentioned above, celery is filled with potassium. Potassium is an essential mineral that helps keep your heart healthy, your muscles functioning properly, and regulates blood pressure.

Celery also contains a phytochemical called phthalides that can help increase blood flow and reduce blood pressure. Celery seed extract, in particular, can help lower blood pressure elevations.

The Side Effects of Overeating Celery

Are there side effects to overeating celery? Most likely! Celery is a low-calorie vegetable with many health benefits and can improve overall wellness when part of a balanced diet. But as with most things, overeating can do more harm than good. Remember that there’s no one-size-fits-all for nutrition, so it’s essential to monitor the effects of celery on your specific body. Here are a few common side effects some people may experience: 

  • Malnutrition
  • Bloating
  • Diarrhea
  • Gas
  • Gastrointestinal issues

The Celery Juice Trend

The wellness world is abuzz with a delicious health trend: celery juice. Proponents of this new green juice fad claim that drinking celery juice first thing in the morning can help improve digestion, boost energy levels, help with weight loss, and clear up skin problems.

You may have noticed the recent celery juice trend and thought to yourself: what is this all about? Is this just another “miracle cure” that will quickly fade away? Or is there something to this trending health craze? 

So, are there any side effects to adding celery to your juicer? No, but it may not have as many health benefits as you think. Celery contains 12 different antioxidants, including vitamin C, beta carotene, and flavonoids which all get juiced out. So, one of the most significant drawbacks to juicing celery is losing the fiber content in the stalk. Consider blending celery instead as part of a smoothie or refreshing drink to retain some nutrient benefits. 

Pro Tip: Want a slight boost in your celery juice? We recommend adding turmeric root to your celery juice to get added anti-inflammatory benefits. The primary active ingredient in turmeric is curcumin, which has powerful anti-inflammatory and antioxidant properties. These properties make it a natural treatment for various health issues, including heart disease, cancer, arthritis, and Alzheimer's disease. 

The Hype Around Celery Juice: What Do Our Dietitians Think?

So, we know now that celery juice is super trendy, but is it that good for you? Three Nutrisense dietitians talk about whether it’s the superfood the internet seems to think it is:

Celery Juice is Lower in Fiber

“Plants such as celery pack powerful phytochemical compounds responsible for antioxidant activities in your body important for healing effects. There is a lack of evidence in the literature to support that juicing has superior benefits over the consumption of whole celery. Remember, celery juice will be lower in fiber. One stalk of celery has about one gram of fiber. I blend my celery with some cucumber, lemon, and apple cider for a nice refreshing drink. It's an easy way to quickly get in those compounds and other fabulous nutrients. It can even encourage healthy eating patterns throughout the day!” 

— Marie Funk, MS, RD, LDN

It Shouldn't be a Meal Replacement

“Celery itself is a great, often underrated vegetable full of fiber and many vitamins and minerals. The fiber can help you feel full when combined with protein and healthy fats on a balanced plate. So including celery with other non-starchy veggies can be a way to reduce inflammation and manage your weight. On the other hand, celery juice isn’t going to offer those same benefits as juicing celery removes the fiber and health benefits that come along with that. While celery juice can provide some hydration and micronutrients, it’s not going to be a magical cure-all (like some online sources may claim). It shouldn’t be a meal replacement.” 

— Jordyn Wallerius, MS, RD, CD

You May Drink More Calories Than You Eat

“As a dietitian, I always recommend food first! Drinking celery juice can be a part of a well-balanced diet and provide some hydration and other nutrients! But drinking juice is not the same as eating food because you can miss out on fiber and often drink more calories than you can eat. Want some celery? Have some as a delicious snack, with some hummus or peanut butter for extra protein/fat.” 

— Randi Yow, RDN, LDN

A Note on Celeriac

Have you ever wondered what celeriac is? Is it just a fancy name for celery? Many people don't know the difference between these two plants, but there is a difference. Celeriac, also known as celery root, is an edible root vegetable that belongs to the Apiaceae family.

It's not often found in mainstream grocery stores, but it's worth seeking out. Celeriac has a mild celery flavor and a crisp, firm texture. It's often used in soups and stews, but it can also be roasted or mashed like potatoes. And it has many health benefits, too: it may help improve bone health, reduce your risk of diabetes, and prevent long-term disease. Try this Cream of Celery and Celeriac Soup to get the benefits of both!

The Effect of Celery on Your Blood Glucose Levels

So, we know that celery is full of health benefits, but can it help manage your blood sugar levels? Yes, because one of the benefits of this vegetable is its effect on your blood glucose levels.

Celery has low sugar content and is low in digestive carbohydrates. These things mean it is not likely to cause blood sugar spikes for most people.

Celery also contains a compound called apigenin, which has been shown to help lower blood sugar levels in mice so more research is needed in humans. In addition, celery has enough fiber and other nutrients that may help regulate blood sugar levels.

A recent study found that participants who ate celery with their meals found that their postprandial blood glucose levels were 19.5 percent lower than those who did not. It makes celery an excellent food for people with diabetes or prediabetes.

Tips to Add Celery to Your Diet

There is something about celery that just screams "healthy." Perhaps it’s the crisp, green texture or the subtle taste that makes it so popular in health-conscious circles.

Here are a few fun tips to help you add it to your diet:

  • Celery is an excellent addition to your salads. Try slicing it up and adding it to your next salad for a bit of crunch. 
  • Celery makes a great snack. Snack on celery sticks with peanut butter or hummus for a quick and easy snack packed with nutrients. 
  • Try adding sliced celery to a chicken or beef stir fry. 
  • Add celery to your favorite soups and stews.
