Calories in Turnip Greens: Nutritional facts for Turnip Greens Types
Turnip greens are the leafy foliage of the Brassica rapa plant, and the calories in turnip greens vary by size and preparation. A single small serving of raw turnip greens (28g) contains 9 calories, while a large raw serving (100g) provides 32 calories. Cooking reduces the calorie count slightly, as a small boiled serving (28g) contains 8 calories and a large boiled serving (100g) provides 29 calories. Sauteed turnip greens align with the boiled variety, containing 29 calories per 100g. One cup of chopped raw turnip greens (55g) contains 18 calories, while a serving of Glory Foods Seasoned Turnip Greens (135g) has 30 calories, and Pictsweet Farms Chopped Turnip Greens (85g) contains 20 calories.
An assessment of the turnip greens nutrition facts reveals a food characterized by a high concentration of vitamins, minerals, and bioactive compounds relative to the low caloric load, with a large raw serving (100g) delivering 5.7g of carbohydrates, including 3.2g of dietary fiber, 1.5g of protein, and only 0.3g of fat. The preparation style alters the nutrient profile slightly, as the calorie density shifts from 32 calories per 100g for raw greens to 29 calories for a boiled version, while the cooking process increases the bioavailability of certain nutrients. The foliage distinguishes itself through an exceptional vitamin profile, providing 251mcg of Vitamin K (209% DV) and 60mg of Vitamin C (67% DV) per large serving. The mineral content proves substantial as well, offering 190mg of calcium (15% DV), 296mg of potassium (6% DV), and 31mg of magnesium (7% DV), supporting bone density and fluid regulation. These greens also contain potent phytochemicals such as glucosinolates, lutein, and beta-carotene, which function as antioxidants and anti-inflammatory agents.
The vegetable's global availability relies on a robust agricultural sector, with major producers like China yielding over 29 million tonnes of turnips and associated greens annually. This cultivation meets significant demand in key markets, where the United States alone imported over $1.4 billion in edible brassicas in 2022. Turnip greens function as a staple ingredient in at least three distinct cuisines, appearing in Southern American stews, Italian pasta dishes like Orecchiette, and Chinese stir-fries. This consistent demand and rising agricultural costs are reflected in the retail pricing, with a single bunch of fresh greens climbing from under $0.89 in the early 2000s to over $1.99 after 2020. Menu prices mirror this economic shift, as a side of greens at Cracker Barrel moved from $2.49 in 2014 to $3.49 in recent years.
Given its nutrient density, turnip greens are a beneficial food for regular consumption and are considered a "superfood" due to the high ratio of nutrients to calories. Organizations like the USDA and the American Heart Association recognize the value of cruciferous vegetables in disease prevention, and a single large serving provides over double the daily requirement for Vitamin K. A suggested consumption rate is to include the vegetable in meals two to three times per week, though individuals on anticoagulant medication must monitor intake carefully. The 32 calories in a large portion of turnip greens require an energy expenditure equivalent to 3 minutes of running or 4 minutes of swimming.

What are the Health Benefits of Turnip Greens?
The nutritional value of turnip greens is defined by the high concentration of Vitamin K, glucosinolates, and dietary fiber found in the leaves. A description of the benefits is listed below.
- Supports Bone Health: The leaves serve as an exceptional source of Vitamin K, a nutrient essential for bone mineralization and calcium absorption. A study by Booth, S. L. (2009), "Roles for Vitamin K in cartilage and bone health," established that adequate Vitamin K intake is associated with higher bone mineral density and a reduced risk of hip fractures.
- Reduces Cancer Risk: The vegetable contains glucosinolates, sulfur-containing compounds that break down into biologically active isothiocyanates, which exhibit anti-carcinogenic properties. A review by Higdon, J. V., et al. (2007), "Cruciferous vegetables and cancer risk in human clinical epidemiological studies," found an inverse association between the consumption of cruciferous vegetables and the risk of various cancers, particularly lung and colorectal cancer.
- Enhances Digestive Function: The greens provide a substantial amount of dietary fiber and water, which facilitate bowel regularity and gut health. A study by Anderson, J. W., et al. (2009), "Health benefits of dietary fiber," confirmed that high-fiber diets significantly lower the prevalence of gastrointestinal disorders and improve overall digestive efficiency.
What are the Downsides of Turnip Greens?
The vegetable's chemical composition presents specific health risks for individuals taking anticoagulants or those prone to kidney stones. The table below shows the potential health risks associated with turnip greens consumption.
- Interference with Blood Thinners: The high Vitamin K content promotes blood clotting, which can counteract the efficacy of anticoagulant medications like Warfarin. A study by Violi, F., et al. (2016), "Interaction between dietary vitamin K intake and anticoagulation by vitamin K antagonists," indicates that sudden increases in Vitamin K intake can destabilize the International Normalized Ratio (INR) in patients on anticoagulation therapy. A safer alternative for those on medication is carrots or green beans, which contain lower levels of Vitamin K. A suggested daily amount is to maintain a consistent intake of no more than half a cup of cooked greens to avoid fluctuations in drug metabolism.
What Phytochemicals are Found in Turnip Greens?
The phytochemicals in turnip greens include glucosinolates (specifically gluconapin and glucobrassicanapin), lutein, zeaxanthin, beta-carotene, and quercetin. These bioactive compounds function as potent antioxidants and anti-inflammatory agents within the body. The glucosinolates are hydrolyzed upon chewing or chopping into isothiocyanates and indoles, which trigger detoxification enzymes in the liver and protect cells from DNA damage.
Are Turnip Greens Good for You?
Yes, turnip greens are good for health because the vegetable offers a dense profile of calcium, Vitamin A, and folate that supports multiple physiological systems. The high nitrate and potassium content supports heart health by helping to regulate blood pressure and improve endothelial function, as noted in the research by Blekkenhorst, L. C., et al. (2018), "Cardiovascular health benefits of specific vegetable types." The presence of lutein and zeaxanthin supports eye health by protecting the retina from oxidative stress, a benefit highlighted by Eisenhauer, B., et al. (2017), "Lutein and Zeaxanthin—Food Sources, Bioavailability and Dietary Variety in Age-Related Macular Degeneration Protection." The vegetable also aids in weight management due to the low caloric density and high fiber content. A study by Slavin, J. L. (2005), "Dietary fiber and body weight," found that increased fiber intake is inversely associated with body weight and body fat.
How Do Calories Change According to Turnip Greens Types?
The calorie count remains relatively consistent across the different types of turnip greens. A serving of Seven Top greens contains 32 calories per 100 grams, representing the baseline for varieties grown specifically for foliage. Purple Top White Globe greens contain a nearly identical value at 30 calories per 100 grams, with the slight decrease attributed to the dual-energy allocation of the plant between root and leaf. Shogoin greens present a slightly lower profile at 28 calories per 100 grams, a consequence of the higher water content and milder tissue structure found in Asian cultivars.
Can You Eat Turnip Leaves?
Yes, turnip leaves are entirely edible and serve as a highly nutritious vegetable comparable to kale or collard greens. Turnip leaves' edible qualities include a peppery, slightly bitter flavor that mellows significantly upon cooking. Traditions across the American South, Italy, and Asia have utilized the greens for centuries, often valuing the foliage more than the root itself. The leaves contain higher concentrations of vitamins and minerals than the turnip root, making the disposal of the tops a waste of valuable nutrition.
What is the Origin of Turnip Greens?
The history of turnip greens traces back to Northern Europe and Western Asia, where the plant Brassica rapa was first domesticated. The species existed in ancient Rome and Greece, where Pliny the Elder described the cultivation of turnips for both the root and the foliage. The vegetable reached the Americas with European colonists in the 16th and 17th centuries, becoming a staple crop in the Southern United States due to the plant's ability to thrive in cool weather and poor soil. The global spread occurred due to the plant's hardiness, leading to the development of distinct varieties in East Asia (Shogoin) and Europe (Rapini/Grelos).
