Kål är bland de mest populära korsblommiga grönsakerna. Det är tätt packat med näringsämnen, inklusive vitala mineraler och vitaminer.

Denna grönsak finns i en mängd olika färger och dess blad kan antingen krympas eller slätas.

Forskning säger sin förmåga att öka hjärthälsan och hjälpa till vid behandling av inflammation och cancer. I det här inlägget behandlar vi mer om vad olika studier säger om kål och dess användning.

  • Vilka är biverkningarna av kål?

Hur är kål bra för dig?

Kål innehåller fyra stora antioxidanter. Dessa är kolin, beta-karoten, lutein och quercetin.

Kolin kan förbättra minnet och bekämpa inflammation. Det kan också förhindra neuralrörsdefekter hos gravida kvinnor (1).

Betakaroten skyddar det mänskliga DNA: n från de skadliga effekterna av rökning (2).

Lutein kan förhindra åldersrelaterad makuladegeneration (3).

Quercetin bekämpar skadliga bakterier och bekämpar sjukdomar (4).

Kål är också rik på vitamin C och K, och B-vitaminer som erbjuder många andra fördelar. Kål finns i olika varianter, inklusive:

  • Cannonball kål (även kallad grönkål, den vanligaste sorten)
  • Bok choy
  • Choy summa
  • Napa kål
  • Savojkål
  • rödkål

Oavsett sort är fördelarna lika. Korsblommiga grönsaker är i allmänhet en av de mest undersökta livsmedelsgrupperna. Kål råkar vara bland de populära. Följande avsnitt kommer att belysa mer om hur det är till nytta att inkludera kål i din vanliga kost.

Hur gagnar kål dig?

Kål är rik på olika antioxidanter, inklusive antocyaniner och sulforafan. Dessa hjälper till att bekämpa inflammation och tillhörande sjukdomar som hjärtsjukdomar och cancer. Fermenterade former av kål kan också öka din matsmältningshälsa.

1. Kan främja hjärthälsa

Rödkål är rik på antocyaniner (5). Dessa föreningar är ansvariga för dess karakteristiska röda färg. Studier kopplar antocyaniner till en minskad risk för hjärtsjukdom, men mer långsiktig forskning är motiverad (6).

Ett högt intag av antocyaniner kan också minska risken för hjärtinfarkt hos unga och medelålders kvinnor. Ytterligare försök bör ge oss mer information om denna aspekt (7). Dessa antocyaniner kan också sänka arteriell styvhet, vilket kan minska blodtrycket (8).

Surkål, en fermenterad kålberedning, främjar också hjärthälsa (9). Man tror att surkål neutraliserar tarmfloran, vars kemiska biprodukter kan härda artärerna. Det behövs dock mer forskning för att upprätta denna anslutning.

Rödkål skyddar också hjärtat genom att minska nivåerna av dåligt kolesterol i kroppen (10).

2. Kan förbättra matsmältningshälsan

Kimchi, en annan jäst mat tillagad av kål, kan främja matsmältningshälsan. Den är rik på probiotika och främjar matsmältningshälsan på liknande sätt som yoghurt och andra mejeriprodukter. Kimchi förhindrar förstoppning och främjar också kolorektal hälsa (11).

Kål är också rik på både olösliga och lösliga fibrer. Den förstnämnda ökar avföringen och främjar regelbundenhet (12). Den senare främjar tarmvänliga bakterier (13).

3. Kan bekämpa inflammation

Även om inflammation i sig inte är dålig, är kronisk inflammation det. Korsblommiga grönsaker, som kål, bekämpar kronisk inflammation (14).

I en studie visade kvinnor som hade det högsta intaget av korsblommiga grönsaker de lägsta nivåerna av inflammation. Studien kopplar delvis intaget av sådana grönsaker till minskad inflammation (15). Detta kan tillskrivas en antioxidant som kallas sulforafan som finns i korsblommiga grönsaker (16). Sulforaphane kan också sakta ner broskskador i lederna (17).

I en annan studie hjälpte kålbladomslag att lindra knäinflammation hos patienter med artros. De kan rekommenderas för dem med knäartros, även om mer forskning är motiverad (18).

Kålfytokemikalier kan också hjälpa till att bekämpa hälsoproblem relaterade till inflammation, inklusive cancer och kranskärlssjukdom (igensatta artärer) (19).

4. Kan erbjuda skydd mot cancer

Forskning pågår kring antiframkallande effekter av sulforafan. På molekylär nivå har denna antioxidant visat lovande resultat (20).

Kål innehåller också en annan uppsättning föreningar som kallas isotiocyanater. Dessa kan avväpna cancerframkallande ämnen genom att få ut dem från deras giftiga tillstånd och spola ut dem från kroppen (21).

Kål innehåller en annan förening som kallas brassinin, som också uppvisar kemopreventiv aktivitet (22).

I rått- och musstudier kunde föreningar i kål (korsblommiga grönsaker, i allmänhet) hämma utvecklingen av cancer i urinblåsan, bröstet, tjocktarmen, levern, magen och lungan (23), (24).

5. Kan hjälpa Diabetesbehandling

Rödkål har antihyperglykemiska egenskaper, vilket kan minska risken för diabetisk nefropati (25). Rödkålsextrakt visar också ett löfte när det gäller att lindra diabetes och dess kärlkomplikationer (26).

I en studie sänkte oral administrering av kålextrakt blodsockernivån hos fastande kaniner och lindrade diabetessymtom hos depancreatiserade hundar (27).

Antocyaninerna i kål kan också ha en roll vid behandling (och till och med förebyggande) av diabetes (28).

6. Kan främja Vision Health

Luteinet i kål bidrar till synhälsan. Lutein (tillsammans med en annan antioxidant som kallas zeaxanthin) skyddar näthinnan och linsen mot ultraviolett ljus. Kål innehåller också spårmängder zeaxantin (29).

Cabbage also contains vitamin C, another nutrient that aids vision. It may regenerate vitamin E inside the eye, which is an antioxidant important for vision health (30).

7. May Strengthen Immunity

The vitamin C in cabbage could strengthen immunity, though more studies are needed to further validate this statement (31). The antioxidant stimulates the white blood cells that help form the first line of defense. It also promotes the maturation of T-cells, which are an important component of the body’s immune system (32).

8. May Help With Weight Loss

Fruits and vegetables containing fiber (including cabbage) can help with weight loss (33). Some individuals also believe in a particular weight loss diet made of cabbages, called the cabbage soup diet.

This diet involves the intake of large amounts of cabbage soup for seven days. You may also consume certain other fruits and veggies, brown rice, chicken, and beef.

Though proponents say it is a good way to lose a few pounds quickly, you shouldn’t be staying on it for more than a week because it lacks in complex carbohydrates, protein, and other vitamins and minerals (34).

9. May Improve Skin Health

Cabbage is rich in vitamin C. This nutrient boosts the production of collagen, a structural protein that helps with skin formation and wound healing (35).

As per mice studies, red cabbage may also have a role in preventing skin cancer (36).

10. Might Strengthen Hair

Cabbage contains quercetin. This antioxidant shows some promise in the treatment of alopecia areata (an autoimmune condition involving sudden hair loss). Mice studies show that subcutaneous injections of quercetin may induce hair growth in preexisting alopecic lesions (37).

We need more research in this regard, though. Of course, the studies have been promising. But we are yet to see how effective the quercetin in cabbage can be in boosting hair growth in humans.

The above benefits can undoubtedly be attributed to the powerful nutrients present in cabbage. Let’s take a look at its nutritional profile.

What Is The Nutrition Profile Of Cabbage?

Calories Amounts Per Selected Serving Total Carbohydrate
Protein Amounts Per Selected Serving Vitamin A Vitamin E (Alpha Tocopherol) Amounts Per Selected Serving Calcium

Including cabbage in your regular diet is one way of benefiting from these nutrients. In the following section, we will discuss how you can do that.

How To Include Cabbage In Your Diet

The first thing to do is pick the right cabbage. You need to choose one that is heavy for its size. Also, ensure the leaves are tight and firm. Loose leaves indicate the cabbage is older.

You can eat this veggie raw, boiled, steamed, roasted, stuffed, or even sautéed. Don’t overcook cabbage as doing so leads to the characteristic sulfurous odor.

Following are the ways you can include cabbage in your diet:

  • Add shredded cabbage to your evening vegetable salad.
  • Add chopped cabbage to the soup you have for dinner.
  • Drizzle roasted cabbage with powdered black pepper, olive oil, and minced garlic and have it as it is.

Eating raw cabbage can offer the greatest amount of nutrients, followed by fermenting and cooking. Plan your cabbage meals accordingly. But before you do that, you should know the possible side effects of cabbage.

What Are The Side Effects Of Cabbage?

Possible Issues During Pregnancy And Breastfeeding

Avoid eating raw cabbage to cut the risk of food-borne illness (38). Ensure you cook cabbage properly before consumption.

Allergies

If you are allergic to other veggies from the cabbage family (like broccoli or cauliflower) (39), stay away from cabbage.

May Lower Blood Sugar Way Too Much

If you are already on diabetes medication, do check with your doctor before you start consuming cabbage (40). This is to ensure your blood pressure doesn’t go way too low.

Hypothyroidism

Cabbage may interfere with the thyroid hormone. If you have hypothyroidism, cut back (or even avoid) cabbage. This is truer with raw cabbage. Consult your doctor too (41).

Conclusion

Cabbage is a nutrient-dense healthy food with a strong nutritional profile. Eating cabbage may help improve your digestive health, fight inflammation, and strengthen your immune system. However, be wary of the side effects. If you have hypothyroidism, check with your doctor before consuming cabbage.

Expert’s Answers For Readers’ Questions

How to store cabbage?

Wrap cabbage tightly in a plastic wrap (if it is already cut) or in a sealable plastic bag (if it is whole). You can store the cabbage in the crisper draw in your refrigerator for up to 2 to 3 weeks.

Is cabbage keto?

Since cabbage is comparatively low in carbohydrates, it can be a part of your keto diet.

Is cooked cabbage is good for you?

Eating raw or lightly cooked cabbage is good for health. Cooking cabbage at high temperatures for long periods destroys the active enzymes in it.

Is cabbage healthier than lettuce?

In terms of proteins and vitamins, cabbage is healthier than lettuce. A regular serving of cabbage meets 60% of the RDA of vitamin C intake, while lettuce only meets about 4% of the RDA of the vitamin (42), (43), (44). Cabbage also contains vitamin B6, while lettuce does not. Hence, cabbage could be a healthier option than lettuce.

Is cabbage water healthy?

Yes, cabbage water is healthy. Vitamins E and C in the vegetable can stimulate the digestive and immune systems. Drinking cabbage water is linked to many benefits, including weight loss, improved gut health, decreased inflammation, balanced hormones, and body detoxification. However, none of them have been scientifically proven.

How long does it take cabbage juice to heal an ulcer?

On average, cabbage juice can heal ulcers after 7-10 days of treatment. In one study, 13 participants with stomach and upper digestive tract ulcers were given around one quart (946 ml) of fresh cabbage juice throughout the day (45).

What are the possible issues of eating cabbage during surgery?

Cabbage may affect blood sugar control during and after surgical procedures. Avoid eating it at least two weeks before a scheduled surgery.
