Mørk chokolade er fyldt med næringsstoffer og er en fremragende kilde til antioxidanter. Selvfølgelig smager det syndigt sødt, men at forkæle sig med det behøver ikke at få dig til at føle dig skyldig mere!

Undersøgelser siger, at et moderat indtag af mørk chokolade kan hjælpe med vægttab. Det kan reducere fordøjelsen og absorptionen af fedt og øge mætheden (1).

Mørk chokolade kan også have fordele for blandt andet hud og hjerte. Det er en kilde til kraftige antioxidanter og andre vigtige næringsstoffer. Den indeholder 50-90% kakaotørstof, kakaosmør og sukker. Det kan også indeholde spor af smør - selvom det i de fleste tilfælde er usandsynligt.

I dette indlæg vil vi undersøge detaljeret, hvad forskning fortæller os om mørk chokolade. Vi vil også se på de mulige bivirkninger, som spiser for meget mørk chokolade kan forårsage.

Hvordan gavner mørk chokolade dig?

Kakao flavanoler i mørk chokolade bidrager til de fleste af fordelene. Disse flavanoler har antioxidantvirkninger, der fremmer hjertesundheden, hjælper med at bekæmpe kræft og øger hjernens funktion. Mørk chokolade kan også hjælpe med vægttab.

1. Kan hjælpe vægttab

Moderat indtag af mørk chokolade kan øge mætheden og kan føre til vægttab.

Forskning tyder på, at mørk chokolade kan have en rolle at spille i vægttab. Det kan mindske ekspressionen af gener involveret i fedtsyresyntese. Dette reducerer fordøjelsen og absorptionen af fedt og kulhydrater og øger dermed mætheden (1).

Forbrug af mørk chokolade kunne også være nyttigt til reduktion af vægtomfang hos overvægtige kvinder med normalvægt (en tilstand, der involverer overskydende kropsfedt med et normalt kropsmasseindeks) (2).

Moderation er dog nøglen. Kun 100 gram mørk chokolade indeholder ca. 600 kalorier (3). Derfor skal du ikke have mere end en terning mørk chokolade på en dag.

2. Kan beskytte din hud

Flavanolerne i mørk chokolade kan beskytte huden mod solskader.

Undersøgelser viser, at diætflavanoler fra kakao tilbyder fotobeskyttelse og forbedrer dermal blodcirkulation (4).

Denne effekt kan tilskrives antioxidanterne (især flavanoler) i mørk chokolade (4).

3. Kan øge hjertesundheden

Antioxidanter i mørk chokolade kan reducere risikoen for hjertesygdomme ved at forhindre oxidation, sænke dårlige kolesterolniveauer og hæve gode kolesterolniveauer.

Det sædvanlige indtag af chokolade kan sænke risikoen for koronar hjertesygdom. Undersøgelser har antydet, at mørk chokolade kan have flere fordele end mælkechokolade. En væsentlig årsag til denne effekt kan være flavonoiderne i mørk chokolade (5).

Nogle kilder hævder, at mørk chokolade kan fremme produktionen af nitrogenoxid, som slapper af blodkarrene og forbedrer blodgennemstrømningen. Vi har dog brug for mere forskning for at fastslå dette.

Der er ingen beviser for, at de, der er beskæftiget med hjerte-kar-sundhed, skal undgå mørk chokolade (eller chokolade generelt) (5).

Undersøgelser viser, at det at spise mørk chokolade mere end fem gange om ugen var forbundet med en 57% lavere risiko for koronar hjertesygdom (6).

Vi ved, at mørk chokolade er lavet af kakao. I henhold til en japansk undersøgelse kan polyphenoler i kakaopulver sænke LDL (det dårlige kolesterol), hæve HDL (det gode kolesterol) og undertrykke oxideret LDL (7).

Det er ikke LDL, men oxideret LDL, der er et problem. Antioxidanterne i kakao kan forhindre LDL i at blive oxideret (8).

4. Kan fremme hjernefunktion

Flavonolerne i mørk chokolade kan hæve stemningen og forbedre kognitiv sundhed hos ældre.

I en undersøgelse foretaget på fem raske forsøgspersoner viste det sig, at indtagelse af mørk chokolade (med 70% kakaoindhold) forbedrer adfærdsmæssig og hjernens sundhed (9). Yderligere forskning er i gang for at uddybe disse mekanismer.

I en anden undersøgelse udført af det samme hold viste det sig, at mørk chokolade forbedrede neurale signaler og sensorisk opfattelse (10).

Regelmæssig indtagelse af kakaoflavanoler kan også være effektiv til forbedring af kognitiv sundhed hos ældre med let psykisk svækkelse (11).

Mørk chokolade fremmer også humør og kan lindre følelsesmæssig stress. Vi har dog brug for yderligere forskning for at forstå de involverede mekanismer (12).

Mørk chokolade indeholder også en forbindelse kaldet epicatechin, som blev fundet at reducere hjerneskade i tilfælde af et slagtilfælde (13). Men ikke al mørk chokolade er skabt ens. Sørg derfor for, at du går gennem listen over ingredienser.

5. Kan hjælpe med at forebygge kræft

Rotteundersøgelser fremhæver en mulig forbindelse mellem indtagelse af mørk chokolade og forebyggelse af tyktarmskræft (14). En diæt inklusive mørk chokolade viste sig at reducere celleproliferation og inflammation.

Dagligt indtag af små mængder flavanoler fra mørk chokolade og andre kilder kan være en naturlig tilgang til potentielt at forhindre tyktarmskræft. Vi har dog brug for mere forskning i denne henseende (15).

Ifølge American Cancer Society kan flavanoler i kakaobønner (mørk chokolade) hjælpe med at reducere skader på celler. Men ifølge rapporten angiver resultaterne ikke, om kræfteffekterne kan tilskrives mørk chokolade, eller om det kun er flavanolerne, som også kan findes i andre fødevarer (16).

Mørk chokoladekakao indeholder også høje koncentrationer af catechiner og procyanidiner, der kan have en gavnlig virkning mod oxidativ stress og kronisk inflammation, som begge er risikofaktorer for kræft (17).

6. Kan hjælpe Diabetesbehandling

Forbrug af mørk chokolade kan sænke blodsukkerniveauet ifølge nogle undersøgelser.

Det er muligt, at kakaopolyphenolerne i mørk chokolade direkte kan påvirke insulinresistens og reducere risikoen for diabetes. De kan inducere dannelsen af betaceller i bugspytkirtlen og stimulere insulinsekretion og derved sænke blodsukkerniveauet. Flere undersøgelser skal udføres for yderligere at analysere de antidiabetiske virkninger af mørk chokolade (18).

Rapporter antyder dog, at mørk chokolade kan have nogle bivirkninger (dog kun sjældent) på mennesker, der har diabetes. Men dette skal endnu valideres med stærk forskning.

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?
