Kool is een van de meest populaire kruisbloemige groenten. Het zit boordevol voedingsstoffen, waaronder vitale mineralen en vitamines.

Deze groente is verkrijgbaar in verschillende kleuren en de bladeren kunnen verschrompeld of glad zijn.

Onderzoek wijst uit dat het de gezondheid van het hart kan verbeteren en kan helpen bij de behandeling van ontstekingen en kanker. In dit bericht bespreken we meer over wat verschillende onderzoeken zeggen over kool en het gebruik ervan.

Inhoudsopgave

  • Hoe is kool goed voor u?
  • Welke voordelen heeft kool voor u?
  • Wat is het voedingsprofiel van kool?
  • Hoe u kool in uw dieet kunt opnemen
  • Wat zijn de bijwerkingen van kool?

Hoe is kool goed voor u?

Kool bevat vier belangrijke antioxidanten. Dit zijn choline, bètacaroteen, luteïne en quercetine.

Choline kan het geheugen verbeteren en ontstekingen bestrijden. Het kan ook neurale buisdefecten bij zwangere vrouwen voorkomen (1).

Beta-caroteen beschermt het menselijk DNA tegen de nadelige gevolgen van roken (2).

Luteïne kan leeftijdsgebonden maculaire degeneratie voorkomen (3).

Quercetine bestrijdt schadelijke bacteriën en bestrijdt ziekten (4).

Kool is ook rijk aan vitamine C en K, en B-vitamines die tal van andere voordelen bieden. Kool is verkrijgbaar in verschillende soorten, waaronder:

  • Cannonball-kool (ook wel groene kool genoemd, de meest voorkomende variëteit)
  • Bok choy
  • Choy-som
  • Napa-kool
  • savooiekool
  • rode kool

Ongeacht de variëteit, de voordelen zijn vergelijkbaar. Kruisbloemige groenten zijn over het algemeen een van de meest onderzochte voedselgroepen. Kool is toevallig een van de populaire. Het volgende gedeelte zal meer licht werpen op de voordelen van het opnemen van kool in uw normale dieet.

Welke voordelen heeft kool voor u?

Kool is rijk aan verschillende antioxidanten, waaronder anthocyanen en sulforafaan. Deze helpen bij het bestrijden van ontstekingen en de bijbehorende aandoeningen zoals hartaandoeningen en kanker. Gefermenteerde vormen van kool kunnen ook uw spijsvertering bevorderen.

1. Kan de gezondheid van het hart bevorderen

Rode kool is rijk aan anthocyanen (5). Deze verbindingen zijn verantwoordelijk voor de karakteristieke rode kleur. Studies koppelen anthocyanen aan een verminderd risico op hartaandoeningen, hoewel meer langetermijnonderzoek gerechtvaardigd is (6).

Een hoge inname van anthocyanen kan ook het risico op een hartinfarct bij jonge vrouwen en vrouwen van middelbare leeftijd verminderen. Verdere onderzoeken zouden ons meer informatie over dit aspect moeten geven (7). Deze anthocyanen kunnen ook de arteriële stijfheid verminderen, waardoor de bloeddruk mogelijk wordt verlaagd (8).

Zuurkool, een gefermenteerde koolbereiding, bevordert ook de gezondheid van het hart (9). Aangenomen wordt dat zuurkool de darmflora neutraliseert, waarvan de chemische bijproducten de slagaders kunnen verharden. Er is echter meer onderzoek nodig om dit verband te leggen.

Rode kool beschermt ook het hart door de hoeveelheid slechte cholesterol in het lichaam te verlagen (10).

2. Kan de spijsvertering verbeteren

Kimchi, een ander gefermenteerd voedsel bereid uit kool, kan de spijsvertering bevorderen. Het is rijk aan probiotica en bevordert een gezonde spijsvertering op een manier die vergelijkbaar is met yoghurt en andere zuivelproducten. Kimchi voorkomt constipatie en bevordert ook de gezondheid van de darmen (11).

Kool is ook rijk aan zowel onoplosbare als oplosbare vezels. De eerste voegt volume toe aan ontlasting en bevordert regelmaat (12). De laatste bevordert darmvriendelijke bacteriën (13).

3. Kan ontstekingen bestrijden

Hoewel een ontsteking op zichzelf niet slecht is, is een chronische ontsteking dat wel. Kruisbloemige groenten, zoals kool, bestrijden chronische ontstekingen (14).

In een onderzoek vertoonden vrouwen die de hoogste inname van kruisbloemige groenten hadden, de laagste niveaus van ontsteking. De studie koppelt de inname van dergelijke groenten gedeeltelijk aan verminderde ontsteking (15). Dit kan worden toegeschreven aan een antioxidant genaamd sulforafaan die aanwezig is in kruisbloemige groenten (16). Sulforafaan kan ook kraakbeenschade in gewrichten vertragen (17).

In een andere studie hielpen koolbladomhulsels de ontsteking van de knie bij patiënten met artrose te verlichten. Ze kunnen worden aanbevolen voor mensen met artrose in de knie, hoewel meer onderzoek gerechtvaardigd is (18).

Cabbage phytochemicals can also help fight health problems related to inflammation, including cancer and coronary artery disease (clogged Arteries) (19).

4. May Offer Protection From Cancer

Research is ongoing on the anticancer effects of sulforaphane. At the molecular level, this antioxidant has shown promising results (20).

Cabbage also contains another set of compounds called isothiocyanates. These may disarm carcinogens by getting them out of their toxic states and flushing them out of the body (21).

Cabbage contains another compound called brassinin, which also exhibits chemopreventive activity (22).

In rat and mouse studies, compounds in cabbage (cruciferous vegetables, in general) could inhibit the development of cancers of the bladder, breast, colon, liver, stomach, and lung (23), (24).

5. May Aid Diabetes Treatment

Red cabbage has antihyperglycemic properties, which can cut the risk of diabetic nephropathy (25). Red cabbage extract also shows promise in alleviating diabetes and its vascular complications (26).

In a study, oral administration of cabbage extracts lowered blood sugar levels in fasting rabbits and relieved diabetic symptoms in depancreatized dogs (27).

The anthocyanins in cabbage could also have a role in treating (and even preventing) diabetes (28).

6. May Promote Vision Health

The lutein in cabbage contributes to vision health. Lutein (along with another antioxidant called zeaxanthin) protects the retina and the lens against the ultraviolet light. Cabbage also contains trace amounts of zeaxanthin (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.
