Temna čokolada je polna hranilnih snovi in je odličen vir antioksidantov. Seveda je pregrešno sladkega okusa, toda pri uživanju tega ni treba, da se počutite več krive!

Študije navajajo, da lahko zmeren vnos temne čokolade pomaga pri hujšanju. Lahko zmanjša prebavo in absorpcijo maščob ter poveča sitost (1).

Temna čokolada ima lahko med drugim koristi tudi za kožo in srce. Je vir močnih antioksidantov in drugih pomembnih hranil. Vsebuje 50–90% kakavovih trdnih snovi, kakavovega masla in sladkorja. Lahko vsebuje tudi sledi masla - čeprav v večini primerov malo verjetno.

V tej objavi bomo podrobno raziskali, kaj nam raziskave govorijo o temni čokoladi. Ogledali si bomo tudi možne neželene učinke, ki jih lahko povzroči uživanje preveč temne čokolade.

Kako vam koristi temna čokolada?

Kakavovi flavanoli v temni čokoladi prispevajo k večini njegovih prednosti. Ti flavanoli imajo antioksidativne učinke, ki spodbujajo zdravje srca, pomagajo v boju proti raku in spodbujajo delovanje možganov. Temna čokolada lahko pomaga tudi pri hujšanju.

1. Lahko pomaga pri hujšanju

Zmeren vnos temne čokolade lahko poveča sitost in povzroči izgubo teže.

Raziskave kažejo, da ima lahko temna čokolada svojo vlogo pri hujšanju. Lahko zmanjša izražanje genov, vključenih v sintezo maščobnih kislin. To zmanjša prebavo in absorpcijo maščob in ogljikovih hidratov ter s tem poveča sitost (1).

Uživanje temne čokolade bi lahko bilo koristno tudi pri zmanjšanju obsega teže pri debelih ženskah z normalno težo (stanje, ki vključuje odvečno telesno maščobo z normalnim indeksom telesne mase) (2).

Vendar je zmernost ključnega pomena. Samo 100 gramov temne čokolade vsebuje približno 600 kalorij (3). Zato ne imejte več kot ene kocke temne čokolade na dan.

2. Lahko zaščiti vašo kožo

Flavanoli v temni čokoladi lahko kožo zaščitijo pred poškodbami sonca.

Študije kažejo, da prehranski flavanoli iz kakava nudijo foto zaščito in izboljšujejo dermalni krvni obtok (4).

Ta učinek lahko pripišemo antioksidantom (zlasti flavanolom) v temni čokoladi (4).

3. Lahko okrepi zdravje srca

Antioksidanti iz temne čokolade lahko zmanjšajo tveganje za srčne bolezni s preprečevanjem oksidacije, zniževanjem ravni slabega holesterola in zvišanjem ravni dobrega holesterola.

Običajni vnos čokolade lahko zmanjša tveganje za koronarne srčne bolezni. Študije so pokazale, da ima lahko temna čokolada več koristi kot mlečna. Eden glavnih razlogov za ta učinek so lahko flavonoidi v temni čokoladi (5).

Nekateri viri trdijo, da lahko temna čokolada spodbuja proizvodnjo dušikovega oksida, ki sprosti krvne žile in poveča pretok krvi. Za to pa potrebujemo več raziskav.

Ni dokazov, da se morajo tisti, ki se ukvarjajo z zdravjem srca in ožilja, izogibati temni čokoladi (ali čokoladi na splošno) (5).

Študije kažejo, da je bilo uživanje temne čokolade več kot petkrat na teden povezano s 57% manjšim tveganjem za koronarno srčno bolezen (6).

Vemo, da je temna čokolada narejena iz kakava. Po japonski študiji lahko polifenoli v kakavovem prahu znižujejo LDL (slab holesterol), zvišujejo HDL (dober holesterol) in zavirajo oksidirani LDL (7).

Težava ni LDL, ampak oksidiran LDL. Antioksidanti v kakavu lahko preprečijo, da bi LDL oksidiral (8).

4. Lahko spodbuja delovanje možganov

Flavonoli v temni čokoladi lahko dvignejo razpoloženje in izboljšajo kognitivno zdravje pri starejših.

V študiji, izvedeni na petih zdravih osebah, je bilo ugotovljeno, da vnos temne čokolade (z 70-odstotno vsebnostjo kakava) izboljša vedenjsko in možgansko zdravje (9). V nadaljevanju pa potekajo nadaljnje raziskave, ki bi podrobneje opredelile te mehanizme.

V drugi študiji, ki jo je izvedla ista ekipa, je bilo ugotovljeno, da temna čokolada izboljšuje nevronsko signalizacijo in senzorično zaznavanje (10).

Reden vnos kakavovih flavanolov je lahko tudi učinkovit pri izboljšanju kognitivnega zdravja pri starejših z blago duševno okvaro (11).

Temna čokolada prav tako spodbuja razpoloženje in lahko ublaži čustveni stres. Vendar pa potrebujemo nadaljnje raziskave, da bi razumeli vključene mehanizme (12).

Temna čokolada vsebuje tudi spojino, imenovano epikatehin, za katero je bilo ugotovljeno, da v možganski kapi zmanjšuje poškodbe možganov (13). Toda vse temne čokolade niso enake. Zato si oglejte seznam sestavin.

5. Lahko pomaga pri preprečevanju raka

Študije na podganah poudarjajo možno povezavo med vnosom temne čokolade in preprečevanjem raka debelega črevesa (14). Ugotovljeno je bilo, da prehrana s temno čokolado zmanjšuje širjenje celic in vnetja.

Dnevni vnos majhnih količin flavanolov iz temne čokolade in drugih virov je lahko naraven pristop k preprečevanju raka debelega črevesa. Vendar v zvezi s tem potrebujemo več raziskav (15).

Po mnenju Ameriškega združenja za boj proti raku lahko flavanoli v kakavovih zrnih (temna čokolada) pomagajo zmanjšati škodo na celicah. Toda v skladu s poročilom rezultati ne navajajo, ali bi učinke proti raku lahko pripisali temni čokoladi ali pa so to samo flavanoli, ki jih najdemo tudi v drugih živilih (16).

Kakav v temni čokoladi vsebuje tudi visoke koncentracije katehinov in procianidinov, ki lahko ugodno vplivajo na oksidativni stres in kronično vnetje, ki sta dejavnika tveganja za raka (17).

6. Lahko pomaga pri zdravljenju diabetesa

Po nekaterih študijah uživanje temne čokolade lahko zniža raven sladkorja v krvi.

Možno je, da lahko polifenoli kakava v temni čokoladi neposredno vplivajo na odpornost proti insulinu in zmanjšajo tveganje za diabetes. Lahko spodbudijo nastajanje beta-celic trebušne slinavke in spodbudijo izločanje inzulina ter s tem znižajo raven sladkorja v krvi. Za nadaljnjo analizo antidiabetičnih učinkov temne čokolade je treba opraviti več študij (18).

Poročila pa namigujejo, da ima lahko temna čokolada nekaj škodljivih učinkov (čeprav le redko) na ljudi s sladkorno boleznijo. Toda to še ni potrjeno z močnimi raziskavami.

7. May Enhance Vision

In a study, dark chocolate exhibited a better ability to improve visual acuity than its white counterpart. This effect was only temporary (for about two hours), however. The long-term effects of dark chocolate on vision health need further research (19).

8. May Promote Gut Health

The good microbes in the gut, namely Bifidobacterium and lactic acid bacteria, ferment dark chocolate and produce anti-inflammatory compounds (20).

In another study, the consumption of foods rich in cocoa flavanols could significantly improve the growth of beneficial gut bacteria (21). Although further research is required, this is a promising finding.

9. May Improve Hair Health

Dark chocolate is rich in cocoa. This cocoa contains proanthocyanidins, compounds that were known to promote hair growth in animal studies (22).

In mice, proanthocyanidins were found to induce the anagen phase of hair growth (23). Anagen is the active growth phase of hair follicles where the hair root divides rapidly, adding to the hair shaft.

More research is warranted to understand if dark chocolate can actually have any impact on hair health.

We have seen some of the nutrients that make dark chocolate beneficial to human health. In the following section, we will further explore its nutritional profile.

What Is The Nutritional Profile Of Dark Chocolate?

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

A bar of dark chocolate (100 grams) with 70-80% cocoa content contains about 600 calories. That is a lot, but obviously, you aren’t going to consume 100 grams of dark chocolate every day (we don’t recommend you do that either).

One ounce of dark chocolate (28 grams) contains about 3 grams of fiber, 27% DV of manganese, 25% DV of copper, 19% DV of iron, and 16% DV of magnesium.

The much-discussed goodness of dark chocolate comes from its cocoa content. Cocoa is replete with plant chemicals (called flavanols) that may protect the heart. It contains two to three times more flavanol-rich cocoa solids than its milk cousin.

The other important nutrients in dark chocolate include iron, magnesium, copper, zinc, and phosphorus – all of which contribute to your overall health (3).

As we discussed, not all dark chocolate is created equal. The market is flooded with different brands. How do you pick the best of the lot?

Though beneficial, dark chocolate can cause certain undesirable effects.

What Are The Side Effects Of Dark Chocolate?

Anxiety

Owing to the caffeine in dark chocolate (and chocolate, in general), excess intake can lead to anxiety issues (24). Hence, consume it in moderation.

Heart Arrhythmia

Dark chocolate does have great benefits for the heart. But the caffeine it contains may cause irregular heartbeat in susceptible individuals. Some research shows a link between chocolate, caffeine, and arrhythmia (25). Hence, moderation is key.

Diabetes

Cocoa might interfere with blood sugar control in diabetes patients (26). More research is ongoing in this regard. Please check with your doctor if you can have dark chocolate if you have diabetes.

Pregnancy And Breastfeeding

For pregnant and breastfeeding women, dark chocolate (and other chocolate, in general) is safe in normal amounts. Don’t go overboard (due to its caffeine content) (27). Consume in moderation.

Other Possible Issues With Caffeine

The caffeine in dark chocolate may also aggravate the following conditions (individuals with these conditions must consume dark chocolate in moderation):

  • Diarrhea
  • Glaucoma
  • High blood pressure
  • Irritable bowel syndrome
  • Osteoporosis

However, there is less information if dark chocolate by itself may cause any of these issues. Please consult your doctor in case you have any of the health conditions.

Conclusion

Dark chocolate is a healthful delicacy. It contains important antioxidants that promote human health. But it also comes with too many calories. Hence, moderation is key. Ensure you have not more than an ounce (or even half) in a day to enjoy its benefits without any issues.

Expert’s Answers For Readers’ Questions

How is dark chocolate different from milk chocolate?

While dark chocolate contains the most cocoa content, milk chocolate is primarily made of milk solids. Dark chocolate also tastes slightly bitter, as opposed to its cousin that tastes milky.

Does dark chocolate contain caffeine?

Yes. In fact, it contains more caffeine than regular milk chocolate. This is because of the high cocoa content in dark chocolate.

How much dark chocolate can you eat in a day?

You may want to stick to 1 to 2 ounces of dark chocolate per day. This can translate to 1 to 2 chocolate ‘squares’ in a dark chocolate bar.

Can you eat dark chocolate at night?

Yes, you can eat dark chocolate at night. There are no contraindications.

Is chocolate bad for the kidneys?

Chocolate usually contains potassium. If you have an advanced stage of kidney disease, check with your doctor before consuming chocolate as potassium could stress the kidneys. Otherwise, chocolate is not bad for the kidneys.

Does dark chocolate cause pimples/acne?

There is no research stating that chocolate may cause acne or pimples. A high-sugar or a high-fat diet may increase sebum production and the chances of acne. If you have acne, you may want to limit your intake of chocolate, among other foods that are high in sugar or fat.

Can dark chocolate cause weight gain?

If consumed in excess, it may add to your weight. Dark chocolate is high in calories. We suggest you stick to an ounce or less of dark chocolate a day.

Is dark chocolate good for babies?

Usually, yes, but in moderation. However, your baby may not like the bitter taste of dark chocolate.
