Зелето е сред най-популярните кръстоцветни зеленчуци. Той е гъсто пълен с хранителни вещества, включително жизненоважни минерали и витамини.

Този зеленчук се предлага в най-различни цветове, а листата му могат да бъдат свити или гладки.

Изследванията заявяват способността му да подобрява здравето на сърцето и да помага при лечението на възпаление и рак. В тази публикация ние разглеждаме повече за това, което различни проучвания посочват за зелето и неговата употреба.

Как зелето е добро за вас?

Зелето съдържа четири основни антиоксиданта. Това са холин, бета-каротин, лутеин и кверцетин.

Холинът може да подобри паметта и да се бори с възпалението. Той може също така да предотврати дефекти на нервната тръба при бременни жени (1).

Бета-каротинът предпазва човешката ДНК от вредното въздействие на тютюнопушенето (2).

Лутеинът може да предотврати свързана с възрастта дегенерация на макулата (3).

Кверцетинът се бори с вредните бактерии и се бори с болестите (4).

Зелето също е богато на витамини С и К и витамини от група В, които предлагат много други предимства. Зелето се предлага в различни сортове, включително:

  • Зелено зеле (наричано още зелено зеле, най-често срещаният сорт)
  • Бок чой
  • Чой сума
  • Напа зеле
  • савойско зеле
  • червено зеле

Без значение от сорта, ползите са подобни. Кръстоцветните зеленчуци като цяло са една от най-изследваните групи храни. Зелето е сред най-популярните. Следващият раздел ще хвърли повече светлина върху това как включването на зелето в обичайната ви диета може да ви бъде от полза.

Как зелето ви носи полза?

Зелето е богато на различни антиоксиданти, включително антоцианини и сулфорафан. Те помагат в борбата с възпалението и свързаните с него заболявания като сърдечни заболявания и рак. Ферментиралите форми на зелето също могат да подобрят вашето храносмилателно здраве.

1. Може да насърчава здравето на сърцето

Червеното зеле е богато на антоцианини (5). Тези съединения са отговорни за характерния му червен цвят. Изследванията свързват антоцианините с намален риск от сърдечни заболявания, въпреки че са необходими по-дългосрочни изследвания (6).

Високият прием на антоцианини може също да намали риска от инфаркт на миокарда при млади и жени на средна възраст. По-нататъшните опити трябва да ни дадат повече информация по този аспект (7). Тези антоцианини могат също да намалят сковаността на артериите, потенциално намалявайки кръвното налягане (8).

Киселото зеле, ферментирал зелев препарат, също насърчава здравето на сърцето (9). Смята се, че киселото зеле неутрализира чревната флора, чиито химически странични продукти могат да втвърдят артериите. Необходими са обаче повече изследвания, за да се установи тази връзка.

Червеното зеле също предпазва сърцето, като намалява нивата на лошия холестерол в организма (10).

2. Може да подобри храносмилателното здраве

Кимчи, друга ферментирала храна, приготвена от зеле, може да насърчи храносмилателното здраве. Той е богат на пробиотици и насърчава храносмилателното здраве по начини, подобни на киселото мляко и други млечни продукти. Kimchi предотвратява запек, а също така насърчава колоректалното здраве (11).

Зелето също е богато както на неразтворими, така и на разтворими фибри. Първият добавя насипно състояние към изпражненията и насърчава редовността (12). Последният насърчава благоприятни за червата бактерии (13).

3. Май се бори с възпалението

Though inflammation by itself is not bad, chronic inflammation is. Cruciferous veggies, like cabbage, fight chronic inflammation (14).

In a study, women who had the highest intake of cruciferous vegetables displayed the lowest levels of inflammation. The study partly links the intake of such vegetables to reduced inflammation (15). This can be attributed to an antioxidant called sulforaphane present in cruciferous vegetables (16). Sulforaphane may also slow down cartilage damage in joints (17).

In another study, cabbage leaf wraps helped relieve inflammation of the knee in patients with osteoarthritis. They could be recommended for those with knee osteoarthritis, though more research is warranted (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.
