About 100 grams (3.5 ounces) or 1 cup of mung bean sprouts has:

  • 7 percent of your daily value (DV) for thiamin (vitamin B1)
  • 10 percent of your DV for riboflavin (vitamin B2)
  • 5 percent of your DV for niacin (vitamin B3)
  • 8 percent of your DV for vitamin B5
  • 5 percent of your DV for vitamin B6
  • 15 percent of your DV for folate (vitamin B9)
  • 15 percent of your DV for vitamin C
  • 28 percent of your DV for vitamin K
  • 18 percent of your DV for copper
  • 5 percent of your DV for iron
  • 5 percent of your DV for magnesium
  • 8 percent of your DV for manganese


Although mung bean sprouts are popular, there are many different types of bean sprouts that are commonly consumed. This means that a number of aspects of bean sprouts may vary, including their age and nutritional content.

Variation in Bean Sprout Nutrients

Commonly consumed bean sprouts are:


  • Black bean sprouts
  • Fava bean sprouts
  • Kidney bean sprouts
  • Lentil sprouts
  • Lima bean sprouts
  • Mung bean sprouts
  • Navy bean sprouts
  • Pinto bean sprouts
  • Soybean sprouts

Bean sprouts are generally recognized as nutrient-rich foods as the sprouting process increases their protein content. In 100 grams (3.5 ounces) of soybean sprouts, you can obtain 13.1 grams of protein, 26 percent of the DV. However, mung bean sprouts have only a fraction of that protein content, with just 3 grams or 6 percent of the DV.


While they're not the richest in protein, mung beans are known for containing very low amounts of carbohydrates: just 5.9 grams in every 100 grams, with 1.8 grams coming from fiber. However, kidney bean sprouts are also low in carbohydrates, with just 4.1 grams of carbs in every 100-gram serving, and have a bit more protein (4.2 grams).

Most bean sprouts are considered to be low in fat. Lentil sprouts, mung bean sprouts and kidney bean sprouts all have between 0.2 and 0.6 gram of fat in every 100 grams of sprouts. This isn't true for all sprouts, however. For example, soybean sprouts have 6.7 grams of fat in a 100-gram serving.



The differences in nutrition between types of sprouts aren't limited to their macronutrient content. There's substantial variation in their vitamin and mineral content too. Antioxidants in bean sprouts also vary quite a bit, though soybean sprouts are generally considered to have the most of these healthy bioactive compounds.

Benefits of Eating Bean Sprouts

Many sprouts are considered to be nutrient-rich, low-carbohydrate functional foods. Mung bean sprouts are particularly beneficial as they're rich in fiber compared to other sprouts but are still low in overall carbohydrates. Other legumes, like lentils, kidney beans, lima beans, pinto beans and black beans, are also considered to be low in carbs and suitable for low-carbohydrate diets.


Eating bean sprouts is also associated with a variety of health benefits. Bean sprouts may:

  • Assist digestion and promote a healthy gut microbiome
  • Combat heat stroke
  • Contain compounds that help prevent sepsis
  • Have detoxifying properties
  • Have antimicrobial and antifungal properties
  • Help prevent cancer
  • Improve metabolism and have anti-diabetic properties
  • Moisturize the skin
  • Reduce inflammation
  • Reduce high blood pressure and prevent heart disease

The vast majority of these beneficial properties are associated with their antioxidant content.

Downsides of Eating Bean Sprouts

Eating raw or lightly cooked bean sprouts is often associated with food poisoning, and thousands of cases have been reported. Although the Food and Drug Administration is constantly working to minimize outbreaks of food-borne illness, this is an ongoing problem.


Lightly cooked and raw sprouts can easily be contaminated with bacteria like ​Escherichia coli​, ​Salmonella typhimurium​, ​Staphylococcus aureus​ and ​Listeria monocytogenes​. The damp, warm conditions that sprouts are grown in unfortunately provide a good environment for these pathogenic bacteria. Usually, the germinating seeds are the source of the contamination.

If you've consumed contaminated bean sprouts, your symptoms may vary substantially. Fever, headache and gastrointestinal symptoms, like diarrhea, are common. However, infection by these bacteria can also lead to serious issues, like convulsions or premature delivery and even death.

Children, older adults, pregnant women and people with compromised immune systems should be especially cautious when consuming bean sprouts as these populations are likelier to experience more serious complications. People in these groups should always avoid consuming raw bean sprouts and only eat sprouts that have been thoroughly cooked.

Cooking Bean Sprouts

Although you should wash your bean sprouts before cooking them, washing alone doesn't remove harmful bacteria. The easiest way to avoid food-borne illness and still obtain the benefits of bean sprouts is to cook them thoroughly. This means that they need to be fully heated, which can be achieved through just about any cooking method.

Steaming, sautéing, boiling and frying are all common ways to cook bean sprouts. Many Asian dishes use sautéed or stir-fried bean sprouts along with noodles or other sources of protein. Because many bean sprouts are young and tender, cooking them completely only takes a minute or two.

If you're not sure of how to cook bean sprouts or which dishes they would work best in, boiling your sprouts is always a safe bet. Some boiled bean sprout dishes include the Korean dish ​kongnamul muchim,​ which uses older soybean sprouts, and the Brazilian ​feijao,​ which utilizes barely sprouted black beans.
