I adore cucumbers. I snack on slices, and add them to salads and jugs of H2O. I use cucumbers to scoop up guacamole, tahini, pesto, or olive tapenade; and I marinate them with other veggies for a chilled side dish.

Some of my clients believe cucumbers are devoid of nutrients, because they’re pale in color and high in water. But the truth is, their fluid content is one of their many perks. Here are all seven ways cukes (which contain about 20 calories and 4 grams of carb) help protect and improve your health.

Cucumbers promote bone health

The top nutrient in cucumbers is vitamin K, which is key for bone health. One cup of cucumber with the peel still on supplies over 20% of the recommended daily target for vitamin K. This nutrient is required for bone formation, and several studies have linked low K levels to osteoporosis and increased fracture risk.

Cukes may boost cardiovascular health too

Cucumbers contain dozens of antioxidants, including flavonoids, which are known to protect against heart disease. The seeds may also be beneficial: In a study published last year, a small group of people with mildly elevated blood fats consumed dried cucumber seed extracts daily. After six weeks they experienced a number of favorable changes, including decreased total cholesterol, decreased “bad” LDL cholesterol, increased “good” HDL, and decreased triglycerides.

They’re hydrating

According to the USDA, one medium cucumber contains 194 grams of fluid. That translates to nearly seven ounces, just an ounce shy of a cup! Adding sliced cukes to water also adds flavor, which can help boost your water intake even more.

And great for weight management

Cucumbers offer a trio of characteristics that promote weight loss. They’re low in calories, but contain filling fiber and fluid. One medium cuke provides a quarter of the calories in a medium-sized apple. And of the 4 grams of total carb in the cucumber, one and a half are from fiber. Scooping up hummus with a medium peeled cucumber rather than 10 pita chips saves 100 calories and 15 grams of carbohydrate, and takes up far more space in your stomach.

Cucumbers may help reduce cancer risk

Along with flax and sesame seeds, kale, broccoli, cabbage, strawberries, apricots, and other plant foods, cucumbers contain a natural substance called lignans. Bacteria in the digestive tract convert lignans into compounds that bind onto estrogen receptors. Some preliminary studies suggest they may protect against estrogen-related cancers, including those of the breast, ovary, uterus, and prostate.

Cucumbers can soothe skin

Popping a few cuke slices on puffy eyes actually makes a lot of sense. The pulp of cucumbers is primarily composed of water, vitamin C, and caffeic acid, a natural chemical that possesses anti-inflammatory properties. The combo triggers a soothing effect on skin, and reduces skin irritations and swelling. For these reasons cucumbers have long been applied topically as a home remedy for both acne and sunburn.

They help combat bad breath

One common cause of bad breath is odor produced when bacteria attack trapped food particles. The fluid in cucumbers, as well as the saliva production triggered by chewing, helps to cleanse the mouth and wash away these smelly culprits.

Cucumber Nutrition: Helps You Detox & Lose Weight

You may have always assumed that cucumbers were full of water but offered little other nutrients. Well, think again when it comes to cucumber nutrition.

What are the benefits of eating cucumbers? As you’ll learn below, they’re more than just a way to make pickles or reduce puffiness around your eyes — cucumber nutrition benefits include fighting free radical damage and inflammation.

Cukes are one of the lowest calorie veggies, yet supply powerful polyphenol compounds that can help naturally slow aging caused by oxidative stress.

Additionally, known among researchers for their anti-diabetic, lipid-lowering and antioxidant activity, cucumbers have a detoxifying, cleansing effect on the body. They’re naturally “cooling” and a great way to prevent dehydration, constipation and overheating.

Cucumber Nutrition Facts

The cucumber (Cucumis sativus) is a widely cultivated “gourd” and member of the Cucurbitaceae plant family. Cucumbers have been studied most in regard to their diuretic effects. This has earned them a reputation as a healing food in both traditional folk medicine and modern medicine.

Technically, is a cucumber a fruit or a vegetable? It’s actually a fruit, although treated more like a vegetable.

Eating cukes can add a decent amount of nutrients to your diet. According to cucumber nutrition data published by the U.S. Department of Agriculture, a half cup of cucumbers with the peel (approximately 52 grams) has about:

7.8 calories
1.9 grams carbohydrates
0.3 gram protein
0.1 gram fat
0.3 gram fiber
8.5 micrograms vitamin K (11 percent DV)
1.5 milligrams vitamin C (2 percent DV)
6.8 milligrams magnesium (2 percent DV)
76.4 milligrams potassium (2 percent DV)

Health Benefits

1. Good Source of Cancer-Fighting Antioxidants

Why are cucumbers good for you when it comes to boosting your immune system? Several bioactive compounds have been isolated from the nutritious cucumber, including cucurbitacins, glucosides, lignans, apigenin and flavonols like fisetin.

After investigating cucumber benefits and the potential free radical-scavenging abilities of cucumbers, researchers involved in one study reported that within cucumbers, the presence of flavonoids and tannins seems be responsible for their free radical scavenging and analgesic effects.

Compounds within cukes work to defend against cancer due to their ability to protect DNA and cells from damage due to oxidative stress. Fisetin is specifically tied to brain health and preservation of cognitive function, while cucurbitacins are known to have cancerous tumor-reducing effects.

Researchers have found that cucurbitacin, a type of triterpene compound, may induce cancerous cell death (a process known as apoptosis). The most significant mechanisms with regard to the apoptotic effects of cucurbitacins are their ability to modify activities via nuclear factors or genes and to activate anti-tumor proteins.

As such, eating plenty of high-antioxidant foods like cucumbers may help lower your risk of cancer.

2. High in Nutrients but Low in Calories

Cucumbers are one of the vegetables with the highest water content. This means cucumber nutrition offers valuable vitamins and minerals, yet is super low in calories — with only about 16 calories per cup.

Since the cucumbers are about 95 percent water, they do a good job of taking up room in your stomach. They can add volume to your meals without weighing you down.

This means you can eat more and feel satiated while still sticking to an overall healthy, low-calorie or low-carb weight loss plan if needed. Plus, cucumber nutrition can help quench thirst and prevent the desire to snack due to dehydration.

3. Helps Detoxify the Body

Cucurbitacins are a category of diverse compounds found in the plants of family Cucurbitaceae, including cucumbers. These compounds can support the digestive tract and liver.

Cucumbers are also a natural diuretic food. This means they can help the body produce more urine to carry out toxins and waste.

Types of Cucumbers

There are dozens of different cucumber varieties grown around the world, but three main varieties of are most widely available today: those used for slicing and eating raw, pickling cucumbers (kirbys) and seedless cucumbers.

Within the Cucurbitaceae plant group, some of the more common cucumber varieties include:

Gherkin
English
Armenian
Diva
Green Burpless
Boston Pickling
Lemon
Marketmore
Persian
Suyo Long

History

The Sanskrit synonym of cucumber is sushitalam, which means “very cooling.” According to Ayurveda, cucumbers have cool, light, astringent, sweet and slightly bitter properties.

The juice from cucumbers has long been used as a natural electrolyte booster before energy drinks like vitamin water existed. Since it has antibacterial properties and is an anti-inflammatory food, the cucumber has been used as a home remedy for acne or to reduce redness and puffiness on the skin.

Cucumber vs. Zucchini vs. Spinach

Cucumber and zucchini are in the same plant family and have a similar appearance, but the two are different in terms of texture and nutritional value. Cucumbers (gourds) have a waxy, bumpy exterior, while zucchinis have a rough and dry exterior.

Cucumbers are typically juicy, cool and crisp, while zucchini is a bit starchier and heartier. Another difference is that the flowers of the cucumber plant are not edible while the flowers of the zucchini plant are edible.

Cucumbers are a bit lower in calories and carbohydrates than zucchini and provide a bit less vitamin C, vitamin B6 and certain phytonutrients. However, cucumber seeds and peels do have some antioxidants, such as flavonoids, lignans and triterpenes.

How do cucumbers compare to leafy greens, such as spinach, in terms of nutrient content? There are more than a dozen different types of flavonoid antioxidants alone that are present in spinach.

Spinach nutrition is packed with nutrients, including:

fiber
vitamin K
vitamin C
vitamin A
manganese
zinc
folate
iron
and selenium

While cucumbers also supply some of the nutrients, they don’t pack the punch that most greens do.

Both spinach and cucumbers are low in carbs and great vegetables to have if you’re eating a low-carb diet. However, unlike cucumbers, which are typically eaten raw or fermented, sautéing, boiling or cooking spinach for just one minute can improve its nutrient absorbability and bring out its taste.

How to Grow

When it comes to choosing the best cukes, you have some options: Look for both regular cucumbers and smaller, bumpier “kirbys.” Kirbys are the kind most often used to make pickles.

When shopping, look for cucumbers that are bright to dark green, firm and don’t have any soft, waterlogged spots.
Whenever possible try to find organic cukes. Cucumber nutrition benefits are most available when you buy organic and unwaxed cucumbers (especially since you want to eat the skin). Because cucumbers are so water-dense, if they’re grown in soil contaminated with pesticides, they’ll likely hold on to a lot of chemicals, which wind up getting passed on to you.
Even organic cucumbers can have wax, but these are made of less harmful substances. The only wax that’s allowed on organically grown cucumbers isn’t synthetic and is free of all chemical contaminants.
When storing cucumbers, keep in mind they do best when kept in very cold temperatures. Keep them in a plastic bag in the refrigerator until you’re ready to use them, but try to have them within three to five days.
You can either peel the skin if you’d like, especially if they’ve been waxed, or leave it on and give the skin a good scrub.

Tips for Growing Cucumbers:

While it’s easy to find cukes in most stores, growing them is easy and cost-effective.
Believe it or not, cucumbers are a tropical fruit/vegetable that thrive when the weather is hot. They also do well in humid climates where water is plentiful.
Plan to grow cucumbers during times of the year when there’s warmer weather and rain. They are sensitive to frost and shouldn’t be planted until the soil temperatures is in the 70-degree range. Wait at least two weeks after the last frost date to plant cucumbers.
Cucumber plants grow in two forms: vining (more popular) and bush. Vines scramble along the ground or clamber up trellises, while bush types form a plant lower to the ground. Bush types are suited to containers and small gardens, but vining types produce more crops.
Plant cucumber seedlings 36 to 60 inches apart, depending on variety. For vines that you plan to have grow upward, space plants one foot apart.
You can help to keep the plants warm and moist by using pine straw, wheat straw, chopped leaves or your favorite organic mulch shortly after planting the seedlings.

Recipes

Unlike most vegetables, cucumbers actually taste better when eaten raw. Because they’re so high in water, they don’t usually come out well when cooked and tend to just turn into a soggy mess.

If plain old cucumbers get boring, try making fermented pickles using some vinegar. Fermentation is what gives the cucumber its distinctively tangy, sour and salty flavor once it’s made into a pickle, plus it contains live microorganisms that have beneficial effects.

You can combine two regular cucumbers and toss with three tablespoons of rice vinegar, two tablespoons chopped herbs of your choice (like dill), and a pinch of sugar and salt.

Is it good to eat cucumber every day? There’s no downside to doing so, considering the low calorie count and other benefits.

However, while pickles have some great nutritional components, such as fiber, vitamin K and even probiotics in some cases, you’ll still want to stick with one to two per day due to the salt content.

The longer you let pickles sit, the stronger taste they’ll develop, but even just 30 minutes allows them to absorb some flavor. If you enjoy the flavor of dill, try this dill pickle recipe that uses a brine of water, vinegar, salt, and dill weed or dill oil.

Risks and Side Effects

Cucumbers seem to be pretty harmless and very rarely cause allergies. Even cucumber extract, which is used in some lab settings, has been shown to be well-tolerated and unlikely to cause side effects.

As mentioned earlier, it’s best to buy organic (ideally unwaxed) cukes whenever you can to avoid high levels of chemicals.

Another thing to consider is the potential for contamination if you make your own fermented pickles. Complex microbiota are responsible for the changes observed during cucumber fermentation, and it’s possible that if your equipment or jar is contaminated with bacteria, you can become sick once eating them.

Use sterile equipment whenever fermenting veggies, and buy organic produce to further limit this risk.

Due to their diuretic effects, should you not eat cucumber at night? This probably won’t be an issue unless you eat large amounts.

While cukes can increase urination, the effect is usually subtle and for most people won’t interfere with sleep.

Conclusion

Cucumbers (Cucumis sativus) are a widely cultivated “gourd” and a member of the Cucurbitaceae plant family. There are many different varieties of cucumbers, but they are typically split into three types: slicing, pickling and seedless.
Eating cukes can add a decent amount of nutrients to your diet. Cucumbers contain very few calories but supply powerful polyphenol compounds. They are known among researchers for their diuretic, anti-diabetic, lipid-lowering, antioxidant, detoxifying and cleansing effects on the body.
Cucumber nutrition benefits include helping balance the body’s pH, improving digestion, treating bloating and constipation, aiding in metabolic and heart health, preventing headaches, hydrating the skin, and depuffing swollen eyes.

9 Health Benefits of Cucumbers

Cucumbers belong to the same plant family as squash, pumpkin, and watermelon (the Cucurbitaceae family). Like watermelon, cucumbers are made up of mostly (95 percent) water, which means eating them on a hot summer day can help you stay hydrated.

However, there’s reason to eat cucumbers all year long. With vitamin K, B vitamins, copper, potassium, vitamin C, and manganese, cucumbers can help you to avoid nutrient deficiencies that are widespread among those eating a typical American diet.

Plus, cucumbers contain unique polyphenols and other compounds that may help reduce your risk of chronic diseases and much, much more.

9 Reasons to Eat Cucumbers

1. Protect Your Brain

Cucumbers contain an anti-inflammatory flavonol called fisetin that appears to play an important role in brain health. In addition to improving your memory and protecting your nerve cells from age-related decline,1 fisetin has been found to prevent progressive memory and learning impairments in mice with Alzheimer’s disease. 2

2. Reduce Your Risk of Cancer

Cucumbers contain polyphenols called lignans (pinoresinol, lariciresinol, and secoisolariciresinol), which may help to lower your risk of breast, uterine, ovarian, and prostate cancers. 3 They also contain phytonutrients called cucurbitacins, which also have anti-cancer properties. According to the George Mateljan Foundation: 4

“Scientists have already determined that several different signaling pathways (for example, the JAK-STAT and MAPK pathways) required for cancer cell development and survival can be blocked by activity of cucurbitacins.”

3. Fight Inflammation

Cucumbers may help to “cool” the inflammatory response in your body, and animal studies suggest that cucumber extract helps reduce unwanted inflammation, in part by inhibiting the activity of pro-inflammatory enzymes (including cyclo-oxygenase 2, or COX-2). 5

4. Antioxidant Properties

Cucumbers contain numerous antioxidants, including the well-known vitamin C and beta-carotene. They also contain antioxidant flavonoids, such as quercetin, apigenin, luteolin, and kaempferol, 6 which provide additional benefits.

For instance, quercetin is an antioxidant that many believe prevents histamine release—making quercetin-rich foods “natural antihistamines.” Kaempferol, meanwhile, may help fight cancer and lower your risk of chronic diseases including heart disease.

5. Freshen Your Breath

Placing a cucumber slice on the roof of your mouth may help to rid your mouth of odor-causing bacteria. According to the principles of Ayurveda, eating cucumbers may also help to release excess heat in your stomach, which is said to be a primary cause of bad breath. 7

6. Manage Stress

Cucumbers contain multiple B vitamins, including vitamin B1, vitamin B5, and vitamin B7 (biotin). B vitamins are known to help ease feelings of anxiety and buffer some of the damaging effects of stress.

7. Support Your Digestive Health

Cucumbers are rich in two of the most basic elements needed for healthy digestion: water and fiber. If you struggle with acid reflux, you should know that drinking water can help suppress acute symptoms of acid reflux by temporarily raising stomach pH; it’s possible that water-rich cucumbers may have a similar effect.

Cucumber skins contain insoluble fiber, which helps add bulk to your stool. This helps food to move through your digestive tract more quickly for healthy elimination.

8. Maintain a Healthy Weight

Cucumbers are very low in calories, yet they make a filling snack (one cup of sliced cucumber contains just 16 calories). 8 The soluble fiber in cucumbers dissolves into a gel-like texture in your gut, helping to slow down your digestion. This helps you to feel full longer and is one reason why fiber-rich foods may help with weight control.

9. Support Heart Health

Cucumbers contain potassium, which is associated with lower blood pressure levels. A proper balance of potassium both inside and outside your cells is crucial for your body to function properly.

As an electrolyte, potassium is a positive charged ion that must maintain a certain concentration (about 30 times higher inside than outside your cells) in order to carry out its functions, which includes interacting with sodium to help control nerve impulse transmission, muscle contraction, and heart function.
