    Cucumbers at a glance

    Cucumbers are a cooling, water-rich food that hydrates you, helps you feel full on very few calories and supports calmer inflammation, with 41% of your daily vitamin K in one whole cucumber eaten with its peel.12

    • What they do for you: they help your body build up its own antioxidant enzymes; in a 30-day pilot study, a daily cucumber drink raised one of them, glutathione peroxidase, by 32.8% in 13 adults over 603
    • In Chinese medicine: a cooling food that helps clear the excess heat that so often shows up in the body as inflammation4
    • How much: a cup or two of slices or a whole cucumber on most days; that 30-day study used the equal of 300 grams of fresh cucumber a day, about one whole cucumber31
    • How to use them: raw with the peel, in cucumber-mint water, as raw fermented pickles, or sautéed with ginger when you want something warm

    Cucumbers are crisp, cooling gourds that are about 95% water, and a whole one with its dark green peel brings you vitamin K, potassium and magnesium for just 45 calories.15 Yes, they're good for you, and I count them among the most hydrating foods you can eat, as well as one of the cooling foods that Chinese medicine uses to ease excess heat in the body.54

    Both of those jobs matter for how you feel day to day. When you run low on water, your body often tells you with a dull headache or a sluggish gut,6 and Chinese medicine looks a layer deeper. As I explain it, a diet high in processed food and sugar, burning the candle at both ends and chronic stress all build heat in your body, and that heat often corresponds to inflammation, an underlying driver of just about every chronic health condition you can think of.4 A cool, water-rich food like cucumber works on both at once, which is why it belongs on your plate most days, peel and all.

    What is a cucumber?

    Quick answer

    A cucumber is the crisp green fruit of Cucumis sativus, a climbing vine in the gourd family, and though botanically it's a fruit, you eat it as a vegetable: raw, pickled or blended into drinks.78 Melons, squash and zucchini are its cousins.

    Botanically, a cucumber is a fruit, because it develops from the plant's flower and carries its seeds, but in the kitchen it's a vegetable, and that's where it sits on my own food lists.8 It belongs to the gourd family, the Cucurbitaceae, along with melons, pumpkins and squash.7

    The mild cucumber you slice for a salad is the result of a long partnership between people and plants. Wild cucumbers are intensely bitter, thanks to compounds called cucurbitacins, and as farmers domesticated the plant, they kept the vines that carried a genetic change switching that bitterness off in the fruit.9 By biblical times, cucumbers were an everyday food in the Near East. As I point out in The Biblio Diet, even while the Israelites were enslaved in Egypt, they ate well, with meat, fish, melons, cucumbers and onions on the table,8 and in the wilderness they still remembered those foods by name: "We remember the fish, which we did eat in Egypt freely; the cucumbers, and the melons, and the leeks, and the onions, and the garlick" (Numbers 11:5).10

    Most of a cucumber is water: 95.2 grams in every 100 grams with the peel, and 96.7 grams peeled, so a whole cucumber carries 287 grams of water, about 9.7 fluid ounces.111 What's left is a small but useful set of nutrients, and the peel holds a surprising share of them. Per 100 grams, cucumber with the peel has 16.4 micrograms of vitamin K against 7.2 peeled, along with more beta-carotene (45 micrograms against 31) and more lutein and zeaxanthin (23 against 16).111 Even a half cup of slices with the peel, at 7.8 calories, gives you 8.5 micrograms of vitamin K, 7% of your daily value.12

    Peel on, more than twice the vitamin K: 16.4 micrograms per 100 grams against 7.2 peeled

    Cucumber's vitamin K is K1, the form green plants make, and your body uses vitamin K to build the proteins that help your blood clot and that work in your bones, so the peel is worth keeping.112 Lab analysis has also found silicon concentrated in the bumpy outer peel, one more reason to eat the skin.13 Alongside its water, a whole cucumber brings 442 milligrams of potassium and 39.1 milligrams of magnesium, two minerals that come up again in the blood pressure research below.1

    What does cucumber do for your body?

    Quick answer

    Cucumber works first through water: every bite brings fluid and potassium, and compounds in the fruit help your gut draw in water and calm inflammatory signals, which lab, animal and small human studies have measured.114153

    Start with the water, because that's most of what you're eating, and few foods carry more of it than a cucumber, so every slice counts toward what your cells, your blood and your kidneys need.1

    Cucumber also seems to help your gut bring water to where it does the most good. You've probably seen what happens when you salt sliced cucumbers for a salad: within minutes, water beads up on the slices, because water follows salt. Your intestines use the same principle when the cells lining your gut move chloride, one half of salt, into the bowel through tiny channels, and water follows it in, which keeps things soft and moving. In human colon cells and mouse colon tissue, a compound purified from cucumber switched on one of those channels, called TMEM16A, and in mice made constipated with a drug, it sped food through the small intestine.14

    Some cucumber varieties also carry an unusual sugar-like molecule called idoBR1, an iminosugar, which your body absorbs and passes out unchanged, and in lab tests on human immune cells and blood, it lowered TNF-alpha, one of the main messengers that switch inflammation on.15 In people, the clearest result comes from that 30-day pilot study, where a daily cucumber drink raised one of the body's own antioxidant enzymes in 13 adults over 60.3 The steps look like this:

    1Water and minerals arrive with every bite

    A whole cucumber with the peel holds 287 grams of water and 442 milligrams of potassium.1

    2Your gut draws water in

    In human colon cells and mouse colon, a compound from cucumber switched on TMEM16A, a channel that moves chloride into the bowel so water follows.14

    3Things keep moving

    In constipated mice, the same compound sped food through the small intestine.14

    4Inflammatory signals calm down

    In lab tests on human immune cells and blood, cucumber's iminosugar idoBR1 lowered the inflammatory messenger TNF-alpha.15

    5Your own antioxidant defenses rise

    In 13 adults over 60, a month of a daily cucumber drink raised glutathione peroxidase, one of the body's own antioxidant enzymes.3

    Chinese medicine and Ayurveda both have a name for that calming effect: cooling.

    Cooling foods like cucumber, celery, aloe vera and coconut help reduce heat in the body, and that heat can contribute to inflammation and dryness.Dr. Josh Axe, DC, DNM, CNSFrom The BIGGEST Causes of Fast-Aging Skin (How to Reverse Aging), The Dr. Josh Axe Show (2025), at 30:39

    Cucumber benefits

    Quick answer

    Cucumbers hydrate you, help you feel full on very few calories and support calmer inflammation, and human studies have tied them to a stronger antioxidant enzyme and lower blood pressure.116317 A concentrated cucumber extract has also eased knee pain in controlled trials, and traditional medicine has long used cucumber to cool and soothe the skin.187

    Where the research stands

    Eaten as a food, cucumber has raised the body's own antioxidant defenses, lowered blood pressure and helped people eat less at a meal in small human studies: a 30-day pilot study in older adults, two blood pressure studies from Indonesia and a lunch trial with a salad that included cucumber.3171916 The controlled trials in larger groups tested a standardized cucumber extract in adults with joint pain, and laboratory research shows how cucumber's compounds act in the gut, the immune system and the skin.182021141522

    Hydrates you from the inside

    Moderate evidenceHuman studyUSDA composition · review of human hydration research

    Cucumbers are 95.2% water with the peel on, so eating a whole one is a little like drinking a small glass of water that comes with potassium and magnesium.1 As I've said on my show, about 20% of your daily water intake comes from food, including fruits and vegetables.56 Hydration shows up in how you feel, too, and when water deprivation is behind a headache, drinking water relieves it within 30 minutes to 3 hours for most people.6

    Along with drinking more clear, filtered water, loading up on water-rich vegetables like celery and cucumber is what I recommend for hydration.23 If you're often thirsty, tired or headachy by midafternoon, our guide to dehydration symptoms can help you spot the pattern, and a bowl of cucumber slices with lunch or a glass of cucumber water is an easy place to start.

    Study takeaway: every cucumber you eat counts toward the water your body needs each day.

    Fills you up for very few calories

    Moderate evidenceHuman studyLunch trial · 46 women, each ate every version of the meal; year-long weight-loss trial · 97 women with obesity, 71 finished

    A whole cucumber has 45 calories, so it adds crunch, volume and water to a meal while barely touching your calorie budget.1 In a Penn State study, 46 women came in once a week over five weeks for the same pasta lunch, and each of them ate every version of the meal. When they ate all of a 300-gram, 100-calorie salad of lettuce, carrots, celery, cucumber and tomatoes, with a little light cheese and fat-free dressing, either before the pasta or with it, they ate 11% fewer calories at the meal overall, 57 fewer than when no salad was served.16

    In a year-long trial that tested the same idea in 97 women with obesity, 71 of whom finished, both groups lost weight, and the women counseled to eat more water-rich fruits and vegetables along with cutting fat lost more weight and reported feeling less hungry than those who only cut fat.24 A plate built on water-rich vegetables like cucumber helps you feel satisfied on fewer calories, which is what makes a lighter way of eating something you can keep doing.

    Study takeaway: a cucumber-rich salad before or with a meal helps you feel full on fewer calories.

    Calmer inflammation and cellular protection

    Emerging evidenceHuman studyPilot study · 13 adults over 60, 30 days, no placebo group; lab and mouse studies

    A cucumber a day can boost your body's own antioxidant defenses. In a 30-day pilot study in Tianjin, China, 13 healthy adults over 60 stirred cucumber juice powder into warm water every morning, a daily amount equal to 300 grams of fresh cucumber, or about one whole cucumber, and there was no placebo group. By the end of the month, glutathione peroxidase, one of the enzymes your cells use to neutralize oxidative stress, rose from 302.60 to 401.84 U/mL, a 32.8% increase. Plasma vitamin C rose 67.1%, red blood cells held up far better against damage (hemolysis fell from 6.19% to 1.55%), and a measure of DNA damage in white blood cells fell 8.9%.3 Plasma antioxidant capacity, malondialdehyde and oxidized LDL didn't change.3 Cucumber powder also scored much lower than lotus root powder on a test-tube antioxidant test, yet in the body cucumber did about as well, which suggests it works at least partly by stirring up your own defenses.3

    Lab and animal studies point the same way. Cucumber's iminosugar idoBR1 lowered TNF-alpha in human immune cells,15 a water and alcohol extract of the fruit protected blood vessel lining cells from an inflammatory challenge in the lab,25 and in mice, tiny vesicles from cucumber juice carrying cucurbitacin B, one of cucumber's bitter compounds, slowed the growth of lung cancer cells and tumors.26 Those findings are early and aren't a cancer treatment, and they're one more reason to keep cucumber among the anti-inflammatory foods you eat every week.

    Study takeaway: a daily cucumber supports the antioxidant enzymes your own cells make.

    Gut support and regularity

    Preclinical evidenceAnimal studyHuman colon cells and constipated mice; gut tissue studies; a tasting trial of 15 adults, each tried all three foods

    Indian traditional medicine has long used cucumber seeds for constipation and treats the fruit as cooling,7 and modern lab work offers one reason. In the colon study described above, the cucumber compound that draws water into the bowel also made isolated strips of mouse colon contract more often.14 An extract of cucumber seeds also relaxed spasms in isolated gut tissue and eased diarrhea in animals.27

    For most people, cucumber is easy on digestion as well. In an Italian trial in which 15 healthy adults each ate 80 grams of common cucumber and of two other cucumber-like vegetables on separate days, gut ultrasound and breath tests showed only mild effects, without significant fermentation or bothersome symptoms.28 With all its water, that makes cucumber a gentle everyday food for regularity, and our guide to natural constipation relief shows how it fits with fiber, movement and fluids.

    Blood pressure support

    Emerging evidenceHuman studyBefore-and-after studies · 14 women with high blood pressure, 2 weeks; 20 older adults

    A whole cucumber gives you 442 milligrams of potassium, 9% of your daily value, and 39.1 milligrams of magnesium, along with plenty of water and almost no sodium.1 In a two-week study in an Indonesian village, 14 women aged 30 to 50 with high blood pressure drank 200 grams of fresh cucumber juice in the morning and again in the evening, with no comparison group. Their average systolic pressure fell from 146.43 to 135.36 mmHg after one week and to 122.66 mmHg after two, and diastolic pressure fell from 91.43 to 80.71 mmHg.17 Seeing their numbers drop in the first week, the women also began cutting back on salt and adding more potassium-rich vegetables and fruits.17 A similar study of 20 older adults in Indonesia also found lower systolic and diastolic pressure after cucumber juice.19 That's just what you'd hope to see from a food this rich in potassium and water. Our guide to foods that lower blood pressure shows how to build a whole day around foods like this, and cucumber is one of the easiest to add to any meal.

    Joint comfort

    Emerging evidenceHuman studyTrials of a standardized cucumber extract · 122 adults vs glucosamine-chondroitin, 180 days; 101 and 80 adults vs placebo

    A concentrated extract of the cucumber fruit has eased knee pain and stiffness in people with osteoarthritis, in one trial by more than twice as much as a standard joint supplement. The extract is standardized to cucumber's iminosugars and taken as a small capsule, and the companies that make or sell it sponsored or helped fund the trials.1821 In a 180-day trial of 122 adults aged 40 to 75 with moderate knee osteoarthritis in India, Cameroon and Wales, people took 10 milligrams of the extract twice a day or 1,350 milligrams of glucosamine-chondroitin twice a day, and neither the people nor the researchers knew who got what. WOMAC scores, which rate knee pain, stiffness and function, fell 70.3% on the cucumber extract against 33.7% on glucosamine-chondroitin.18 The extract group's average score dropped from 83.5 to 41.51 by day 90 and kept falling to 24.81 by day 180, while the glucosamine-chondroitin group went from 84.2 to 56.58 by day 90 and then held near 55.57. The extract did better at every visit from day 30 on, pain on a visual scale fell 46.3% against 25.6%, and no side effects were reported.18

    In the two placebo-controlled trials that followed, the extract eased pain over 6 months in 101 adults with knee osteoarthritis, 91 of whom finished, more at the higher dose,20 and in 80 adults with mild to moderate joint pain, 20 milligrams a day for 60 days lowered WOMAC scores significantly by day 30 and day 60, an average improvement of 31.79% per person, though the difference from placebo over time wasn't statistically significant.21 In lab tests, cucumber's iminosugar idoBR1 lowered TNF-alpha, a likely part of how the extract works.15

    Skin moisture and comfort

    Traditional useTraditional useIndian traditional medicine and Ayurveda · lab studies of skin enzymes

    As a boy, I remember watching movies where women relaxed through a facial with cucumber slices over their eyes and a green mask on their faces, and thinking how strange that was. But cucumbers are full of moisture, and they bring moisture to your skin.29 Traditional medicine in India has long used cucumber for the skin, for swelling and for sunburn, and Ayurveda applies the fruit to soothe sunburn irritation.725 In the lab, freeze-dried cucumber juice blocked hyaluronidase and elastase, two enzymes that break down the hyaluronic acid and elastin that keep skin plump and springy,22 and silicon gathers in the bumpy peel.13 Our guides to how to hydrate skin and sunburn relief round out the picture, and a few cool slices on tired skin after a day in the sun are an easy way to start.

    Blood sugar and cholesterol support

    Cucumber seeds have their own traditional uses,7 and in a 6-week placebo-controlled trial of 47 adults with high cholesterol in Iran, a 500-milligram capsule of cucumber seed extract taken once a day lowered total cholesterol, LDL and triglycerides and raised HDL compared with placebo.30 Mice given a cucumber peel extract for 10 days before a drug that induces diabetes, and through day 15, kept their blood sugar and blood fats much closer to normal,31 which fits the antidiabetic potential that a review of cucumber's research describes.7 For your own plate, a side of sliced cucumbers with a protein-rich meal is a low-sugar way to add volume and crunch.

    Cucumber in Chinese medicine and Ayurveda

    Quick answer

    In Chinese medicine, cucumber is a cooling, yin-building food that clears excess heat and brings moisture to the body, and in Ayurveda it's a cooling food that suits the hot, intense pitta type.42932

    Chinese medicine and Ayurveda both sort foods by what they do to the body, and both put cucumber firmly on the cooling side. In my book Ancient Remedies, I explain that traditional Chinese nutrition categorizes foods as hot or cold, based not only on their temperature but also on the way they affect the body, and uses them to balance the body's internal system.4 Cucumbers are on my list of cooling foods, alongside celery, melons, watermelon, coconut water, leafy greens, radishes and zucchini.4 My Anti-Inflammatory Reset puts it in modern terms: in traditional Chinese medicine, lingering heat is what modern medicine would call chronic inflammation, and greens help clear it.33 Cucumber is also a yin-building food, one of the foods like sweet potatoes and watermelon that bring coolness and moisture to the body, and I recommend foods like these to help ease hot flashes.294

    The point of sorting foods this way is to match them to the person eating them.

    Some foods are warming and some foods are cooling, and I started explaining this a lot to my patients with hypothyroidism.Dr. Josh Axe, DC, DNM, CNSFrom The Spice That Fights Inflammation Better Than Ibuprofen | Dr Shivani Gupta, The Dr. Josh Axe Show (2026), at 33:30

    As I've pointed out, a lot of women with hypothyroidism eat salads and drink cold smoothies and ice drinks all day long, and that makes things worse for them than warming foods like ginger and warm soups would.34 If you run cold, keep cucumber on the menu and change how you serve it: pair it with ginger, take it out of the refrigerator a while before you eat it, or cook it into a warm dish like the ginger-sautéed cucumbers in the recipes below.

    Ayurveda reads cucumber the same way. Indian traditional medicine describes it as a refrigerant, a cooling remedy, and has used it for excessive thirst and overheating,7 and in the Ayurvedic diet, cooling foods balance the pitta dosha, the body type tied to heat and intensity.35 Pitta types are focused and intense, but they can lean toward inflammation, and cooling foods like cucumbers and leafy greens serve them well.32 For pitta, I recommend plenty of anti-inflammatory foods, from fruits like figs, pineapple, pomegranate and kiwi to cooling foods like cucumber, celery and yogurt, to keep that body type cool.35 I'm a vata meets pitta myself, so my own focus is keeping my body hydrated.35

    Eating with the seasons matters here as well. In summer, I recommend cooling foods like cucumber, melon and salads with little seasoning,4 and summer is when cucumbers, zucchini, tomatoes, melons and berries are at their best.36 For most of the year, I typically don't like a lot of raw foods, but if you're going to eat salads, spring and early summer are when your body can tolerate them best.37 In the colder months, that's your cue to enjoy cucumbers pickled, or warm with ginger.

    Types of cucumbers

    Most cucumbers you'll find fall into three groups:

    • Slicing cucumbers. The long, smooth, dark green cucumbers for salads and eating raw. From the garden, they're best picked at any size before they get over-large, with big seeds and yellowing skin.38
    • Pickling cucumbers. Shorter, bumpier cucumbers, often sold as kirbys, with firm flesh that stays crisp in brine. Growers try to pick them at a uniform size, and they're very good in salads too.38
    • Seedless (English) and Persian cucumbers. Long English cucumbers and small Persian cucumbers have thin skins and tiny seeds, so they're easy to eat whole, peel and all.

    Other varieties you'll see in seed catalogs and at farmers markets include gherkins, Diva, Green Burpless, Boston Pickling, lemon cucumbers (round and yellow), Marketmore and Suyo Long. Some varieties are naturally less bitter than others, which is worth knowing if you grow your own.38 Cucumber's cousins are fun to try as well: zucchini is a squash in the same plant family, the grape-sized cucamelon is another relative, and in southern Italy, local melon varieties are picked unripe and eaten just like cucumbers.28

    How to use cucumbers

    Cucumbers need almost no preparation, so the easiest way to eat more is to keep a few in the refrigerator, ready to slice.

    Cucumber water. Add slices and a few mint leaves to a pitcher of filtered water and let it chill for a few hours.
    Salads and bowls. Toss cucumber with tomatoes, red onion and fresh herbs, or pile it onto grain bowls and lettuce wraps.
    Smoothies. Blend cucumber with pineapple, spinach and mint for a cleansing smoothie,37 or try one of these green smoothie recipes.
    Dips. Grate cucumber into tzatziki made with goat's or sheep's milk yogurt, or use thick slices in place of crackers for hummus.
    Cool slices for tired eyes. Lay chilled slices over closed eyes while you rest, an old beauty habit people still reach for because it feels so soothing.
    Warm. Sauté thick half-moons with ginger and garlic for a minute or two, or simmer them into a soup.

    Cucumber water

    Cucumber water is the simplest way to drink more of what cucumbers offer: slice a cucumber into a pitcher of filtered water, add mint or a squeeze of lemon if you like, and let it sit in the refrigerator, a simple drink that also has a place in a seasonal cleanse.

    You can also do some cucumber and mint water, or even put organic strawberries in there. Have a refreshing drink like that regularly to support kidney detoxification.Dr. Josh Axe, DC, DNM, CNSFrom If You Do One Detox a Year — Do It Now, And Here's How, The Dr. Josh Axe Show (2025), at 25:42

    Our guide to cucumber water has more ways to make it, and a pitcher in the refrigerator makes it easy to keep sipping through a warm afternoon.

    Pickles

    Pickling keeps cucumbers on the table long after summer ends. On my food list, pickles belong with the raw fermented vegetables, and vinegar free is best,8 which means pickles made the traditional way, with a salt brine and time, so the cucumbers truly ferment. Our guide to fermented pickles shows you how to make them at home, and our guide to pickle juice covers what to do with the brine.

    How to buy, store and grow cucumbers

    Buying. Choose firm cucumbers with even color and no soft spots. A yellowing, oversized cucumber has gone past its best, with big seeds.38

    Organic and unwaxed. Because you eat the peel, buy organic when you can. Cucumbers rank No. 31 of 47 on the Environmental Working Group's 2026 list of pesticide residue in produce, in the middle of the pack rather than on the Dirty Dozen,39 and our guide to the 2026 Dirty Dozen and Clean 15 has the full list. Many non-organic cucumbers are also coated with wax. In the U.S., waxed produce has to be labeled, on the package or on the store's sign for loose produce, and the coatings must be approved food additives or substances recognized as safe,40 while produce labeled organic may carry only a nonsynthetic wax, such as wood rosin.41 When you bring cucumbers home, I recommend soaking them in water and baking soda for 1 to 2 minutes, the way I suggest washing produce in general,42 then scrubbing each one under cool running water just before you eat it. If yours is waxed, you can peel it, knowing the peel carries most of the vitamin K.111

    Storing. Cucumbers keep best cool and humid, at about 55°F, which most kitchens can't offer, so keep them in the refrigerator, where they'll last about a week.38

    Growing. Cucumbers love warm weather and are easy to grow. Sow the seeds directly in the garden after the last frost, once the soil is at least 70°F an inch down, about half an inch deep.38 Give vining types 2 to 3 feet on each side of the row, or plant hills of three or four seeds 5 to 6 feet apart; bush types fit small gardens with 2 to 3 feet between rows, and a 3- to 4-foot trellis saves space and gives you straight fruit.38 Thin the seedlings to 8 to 12 inches apart, give the plants about an inch of water a week, and wait until the soil is above 75°F before you mulch with straw or compost.38 Pick slicers before they get over-large, and leave the vines alone when they're wet, since handling wet vines can spread disease.38 Check our guide to summer vegetables for what else to plant beside them.

    Cucumber recipes

    Cucumbers shine raw, and they take well to a quick sauté with ginger when you'd rather eat them warm. Start with a green drink from my family, then try the recipes below.

    My mom's morning green drink

    In the Cancer Support Protocol, I share the green drink my mom made every day: spinach, celery, cucumber, cilantro, lime and a green apple, blended or juiced, with a few drops of stevia if needed.43 It puts cucumber and greens together in one glass first thing in the day. The chickpea salad in my recipe collection is another easy one, pairing a diced English cucumber with chickpeas, red onion, parsley and tomato.4

    Cucumber side effects and who should be careful

    Cucumbers rarely cause trouble, and the few exceptions are easy to manage.

    Bitter cucumbers. Modern cucumbers were bred to be mild,9 but now and then one turns bitter, most of all near the skin and at the blossom end.38 Reported poisonings from cucurbitacins, the bitter compounds, have involved bitter zucchini and squash, with severe vomiting and diarrhea,4445 so if a cucumber tastes unusually bitter, spit out the bite and toss the cucumber.

    Warfarin and vitamin K. Vitamin K counters the blood thinner warfarin, and a whole cucumber with the peel carries 49.4 micrograms of it, 41% of your daily value.112 On warfarin, the goal is steadiness: eat roughly the same amount of cucumber and other vitamin K-rich greens from one day to the next instead of avoiding them, and let your prescriber know if your diet shifts a lot.12 Interaction check: Low.

    Pollen allergy. Some people with ragweed allergy get an itchy or tingling mouth from raw cucumber, melon, banana or zucchini, a reaction called oral allergy syndrome, and it usually comes from raw rather than cooked food.4647 If that happens to you, try cucumber cooked, and if your lips or throat swell or you have trouble breathing, get emergency care at once.

    A sensitive gut. In a survey of 493 adults in southern Italy, 16.3% of those who ate common cucumber linked it with mild digestive discomfort,28 and if you have inflammatory bowel disease or a low body temperature, I recommend skipping salads and focusing on steamed vegetables.37 Peeled, warm cucumber, like the ginger sauté above, is the gentlest way to keep it in your diet.

    The bottom line

    Should you eat cucumbers?

    Yes. Cucumbers are about 95% water, so they hydrate you and fill your plate for very few calories, and one whole cucumber with the peel gives you 41% of your daily vitamin K plus potassium and magnesium. In a 30-day pilot study of older adults, a daily cucumber drink raised one of the body's own antioxidant enzymes, and both Chinese medicine and Ayurveda prize cucumber as a cooling food, especially for people who run hot.

    Eat them raw with the peel in summer, sip cucumber-mint water through the day, keep a jar of raw fermented pickles in the refrigerator, and sauté them with ginger when you'd rather eat something warm. Cucumber is one of the easiest ways to bring more water, more vegetables and a little more cooling into your day.

    Cucumbers: frequently asked questions

    Are cucumbers good for you?

    Yes. Cucumbers are about 95% water, and one whole cucumber with the peel gives you 45 calories, 41% of your daily vitamin K and 9% each of your potassium, magnesium and vitamin C.12 In a 30-day pilot study with no placebo group, a daily cucumber drink raised glutathione peroxidase, one of the body's own antioxidant enzymes, by 32.8% in 13 adults over 60.3

    What are the benefits of eating cucumbers?

    Cucumbers hydrate you, help you feel full on very few calories and support calmer inflammation and regular digestion.116314 In a two-week study of 14 women with high blood pressure, with no comparison group, average systolic pressure fell from 146.43 to 122.66 mmHg while they drank cucumber juice twice a day.17

    What does cucumber do for your body?

    Cucumber hydrates your body, helps your gut draw in water and supports calmer inflammation. It's about 95% water with potassium,1 and in human colon cells and mouse colon, a cucumber compound switched on a channel that pulls water into the bowel and sped food through the intestines of constipated mice.14 In lab tests on human immune cells, cucumber's iminosugar idoBR1 lowered the inflammatory messenger TNF-alpha.15

    What vitamins are in cucumbers?

    Vitamin K leads, with 49.4 micrograms in one whole cucumber with the peel, 41% of the daily value, followed by pantothenic acid at 16% and vitamin C at 9%.12 A whole cucumber also gives you 14% of your daily copper, 10% of your manganese and 9% each of your potassium and magnesium.12

    How many calories are in a cucumber?

    A whole 8¼-inch cucumber with the peel (301 grams) has 45 calories, a half cup of slices with the peel has 7.8, and a cup of peeled slices has 12.111

    Is it OK to eat cucumber every day?

    Yes. A cucumber a day is a healthy habit for most people, and the 30-day pilot study gave 13 older adults the equal of about one whole cucumber a day.3 The few cautions, for people who take warfarin, people with ragweed allergy and anyone who gets an unusually bitter cucumber, are in the side effects section above.

    Should you eat the cucumber peel?

    Yes, when you can. Per 100 grams, cucumber with the peel has 16.4 micrograms of vitamin K against 7.2 peeled, and lab analysis finds silicon concentrated in the bumpy peel.11113 Buy organic or unwaxed cucumbers and scrub them, or peel a waxed one if you'd rather.4041

    Is cucumber a fruit or a vegetable?

    Botanically, a cucumber is a fruit, since it grows from the flower and holds the seeds, but you eat it as a vegetable, and that's where it sits on my own food lists.8

    What are pipino benefits?

    Pipino is the Tagalog name for cucumber, so pipino benefits are cucumber benefits.48 It's about 95% water, a whole one with the peel has 45 calories and 41% of your daily vitamin K, and in Chinese medicine it's a cooling food that helps clear excess heat.14

    Are there cucumber benefits for men?

    Yes, the same ones women get: hydration, potassium and vitamin K for very few calories, and support for calmer inflammation.1 Men took part in the human studies, too. Eight of the 13 older adults who drank cucumber in the 30-day pilot study were men,3 and so were 62 of the 122 adults in a 180-day trial that compared a cucumber extract with glucosamine-chondroitin for knee osteoarthritis, where WOMAC scores fell 70.3% on the extract.18

    Are there cucumber benefits for women?

    Yes. In perimenopause, I recommend more hydrating foods like cucumbers and watermelon, and in Chinese medicine, cucumber is a yin-building food that brings coolness and moisture to the body to help ease hot flashes.29 The fullness research was done in women, too: in a Penn State lunch study, 46 women ate fewer calories at lunch when they finished a big, low-calorie salad that included cucumber.16

    Is cucumber water good for you?

    Yes. Cucumber water helps you drink more through the day, and I recommend cucumber and mint water, taken regularly, to support kidney detoxification.37 Slice a cucumber into a pitcher of filtered water, add a few mint leaves and keep it in the refrigerator.

    Are pickles good for you?

    Yes, when they're raw and naturally fermented. On my food list, pickles belong with the raw fermented vegetables, and vinegar free is best.8 Pickle brine has research of its own: in a 28-day randomized trial of 82 adults with cirrhosis and frequent muscle cramps, 74 of whom finished, sipping pickle brine at the start of a cramp eased cramp severity more than sipping tap water.49

    Can cucumbers help you lose weight?

    They can help, because a whole cucumber has only 45 calories and adds volume and water to your meals.1 In a lunch study of 46 women who each ate every version of the meal, eating all of a 100-calorie salad that included cucumber cut meal calories by 11%, and in a year-long trial of 97 women with obesity, 71 of whom finished, those counseled to eat more water-rich fruits and vegetables lost more weight and reported less hunger.1624

    Are cucumbers good for your skin?

    Yes, for moisture and soothing. Cucumbers are full of moisture, and they bring moisture to your skin;29 traditional medicine in India has long used them for sunburn and irritated skin;725 and in the lab, freeze-dried cucumber juice blocked two enzymes that break down the skin's hyaluronic acid and elastin.22

    Freshness & update log

    November 7, 2026 — Rewrote the page in full under Dr. Axe's byline. The previous version, "Cucumber Nutrition Can Help You Detox & Manage Weight," gave half-cup nutrition and ten benefits; before taking anything out, we searched Dr. Axe's protocols, books and shows, traditional sources and the research. This version keeps and builds on what held up: the nutrition facts, now per whole cucumber and per cup peeled from USDA, with the vitamin K corrected to K1 and the peel's share shown; hydration and fullness for few calories, now with the lunch trial and the year-long weight-loss trial; antioxidant and cancer-related claims, now as calmer inflammation and cellular protection, led by the 30-day human pilot study and with the lab and mouse work labeled; detox, now as hydration and Dr. Axe's cucumber-mint water for the kidneys; skin and tired eyes, as traditional uses with his own words; digestion, heart health and blood sugar at their evidence levels; the Ayurvedic history; types of cucumbers; buying organic and the rules on wax; growing tips, now from university extension guidance; and every recipe, plus a tzatziki made with goat's or sheep's milk yogurt, a cold avocado soup, a quick dill salad sweetened with raw honey, ginger-sautéed cucumbers and his mom's morning green drink. We took out claims we couldn't support: vitamin A in the skin, fisetin, alkalizing the blood, acne and scars, a lignan heart claim drawn from other foods, a headache claim drawn from magnesium studies, an essential-oil eye paste, a daily pickle limit and storage times with no source; the comparison with spinach became links to cucumber's cousins. It adds how cucumbers work in your body, Chinese medicine and Ayurveda, the trials of a cucumber extract for joint pain, Dr. Axe's own words on cucumbers, a Dr. Axe Score (5.1), three charts, a step diagram and one safety section, with 49 references.
