Varza este printre cele mai populare legume crucifere. Este plin de nutrienți, inclusiv minerale și vitamine vitale.

Această legumă este disponibilă într-o varietate de culori, iar frunzele sale pot fi fie înghesuite, fie netede.

Cercetările afirmă capacitatea sa de a spori sănătatea inimii și de a ajuta la tratamentul inflamației și cancerului. În acest post, acoperim mai multe despre ceea ce afirmă diverse studii despre varză și despre utilizările sale.

Cum este bine varza pentru tine?

Varza conține patru antioxidanți principali. Acestea sunt colina, betacarotenul, luteina și quercetina.

Colina poate îmbunătăți memoria și combate inflamațiile. De asemenea, poate preveni defectele tubului neural la femeile gravide (1).

Beta-carotenul protejează ADN-ul uman de efectele negative ale fumatului (2).

Luteina poate preveni degenerescența maculară legată de vârstă (3).

Quercetina combate bacteriile dăunătoare și combate bolile (4).

Varza este, de asemenea, bogată în vitaminele C și K și vitaminele B, care oferă o mulțime de alte beneficii. Varza este disponibilă în diferite soiuri, inclusiv:

  • Varză de ghiulea (numită și varză verde, cel mai frecvent soi)
  • Bok choy
  • Choy sum
  • varză Napa
  • varza creata
  • varza rosie

Indiferent de varietate, beneficiile sunt similare. Legumele crucifere, în general, sunt unul dintre cele mai cercetate grupuri de alimente. Varza se întâmplă să fie printre cele populare. Următoarea secțiune va arăta mai multă lumină asupra modului în care vă poate aduce beneficii includerea verzei în dieta obișnuită.

Cum vă avantajează varza?

Varza este bogată în diverși antioxidanți, inclusiv antociani și sulforafan. Acestea ajută la combaterea inflamației și a afecțiunilor asociate, cum ar fi bolile de inimă și cancerul. Formele fermentate de varză vă pot stimula, de asemenea, sănătatea digestivă.

1. Poate promova sănătatea inimii

Varza roșie este bogată în antociani (5). Acești compuși sunt responsabili pentru culoarea roșie caracteristică. Studiile leagă antocianinele de un risc redus de boli de inimă, deși sunt necesare mai multe cercetări pe termen lung (6).

Un aport ridicat de antociani poate reduce, de asemenea, riscul de infarct miocardic la femeile tinere și de vârstă mijlocie. Încercările ulterioare ar trebui să ne ofere mai multe informații despre acest aspect (7). Aceste antociani pot reduce, de asemenea, rigiditatea arterială, reducând potențial tensiunea arterială (8).

Varza, un preparat de varză fermentat, promovează, de asemenea, sănătatea inimii (9). Se crede că varza murată neutralizează flora intestinală, ale cărei subproduse chimice ar putea întări arterele. Cu toate acestea, sunt necesare mai multe cercetări pentru a stabili această conexiune.

Varza roșie protejează, de asemenea, inima prin reducerea nivelului de colesterol rău din organism (10).

2. Poate îmbunătăți sănătatea digestivă

Kimchi, un alt aliment fermentat preparat din varză, poate promova sănătatea digestivă. Este bogat în probiotice și promovează sănătatea digestivă în moduri similare cu iaurtul și alte produse lactate. Kimchi previne constipația și, de asemenea, promovează sănătatea colorectală (11).

Varza este, de asemenea, bogată atât în fibre insolubile, cât și în fibre solubile. Primul adaugă volum în scaune și promovează regularitatea (12). Acesta din urmă promovează bacteriile prietenoase cu intestinele (13).

3. Poate lupta împotriva inflamației

Deși inflamația de la sine nu este rea, inflamația cronică este. Legumele crucifere, cum ar fi varza, luptă împotriva inflamației cronice (14).

Într-un studiu, femeile care au avut cel mai mare aport de legume crucifere au prezentat cele mai scăzute niveluri de inflamație. Studiul leagă parțial aportul de astfel de legume la inflamația redusă (15). Acest lucru poate fi atribuit unui antioxidant numit sulforaphane prezent în legumele crucifere (16). Sulforafanul poate încetini, de asemenea, deteriorarea cartilajului la nivelul articulațiilor (17).

Într-un alt studiu, împachetările cu frunze de varză au ajutat la ameliorarea inflamației genunchiului la pacienții cu osteoartrita. Acestea ar putea fi recomandate celor cu osteoartrita genunchiului, deși sunt necesare mai multe cercetări (18).

Fitochimicalele din varză pot ajuta, de asemenea, la combaterea problemelor de sănătate legate de inflamație, inclusiv a cancerului și a bolilor coronariene (arterele înfundate) (19).

4. Poate oferi protecție împotriva cancerului

Cercetările sunt în curs cu privire la efectele anticanceroase ale sulforafanului. La nivel molecular, acest antioxidant a dat rezultate promițătoare (20).

Varza conține, de asemenea, un alt set de compuși numiți izotiocianați. Acestea pot dezarma agenții cancerigeni scoțându-i din stările lor toxice și scoțându-i din corp (21).

Varza conține un alt compus numit brassinin, care prezintă, de asemenea, activitate chemopreventivă (22).

În studiile la șobolani și șoareci, compușii din varză (legume crucifere, în general) ar putea inhiba dezvoltarea cancerelor de vezică, sân, colon, ficat, stomac și plămâni (23), (24).

5. Poate ajuta la tratamentul diabetului

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.
