22 Proven Health Benefits of Cocoa

Everyone loves the taste of chocolate, but most people are unaware of its amazing health benefits. Cocoa contains polyphenols, which are rich in antioxidants and have an important nutritional value.

Cocoa consumption can improve heart and blood vessel health and neurodegenerative diseases, make you happy, and give you great skin.

Read this post to learn more about the amazing health benefits of cocoa.


For hundreds of years, cocoa has been used in body rituals and medicine throughout the world. Cocoa originated in the Americas and spread to Europe over time. Cocoa is used to reduce weight gain, fatigue, stimulate the nervous system, and improve digestive function, among others [R].

Interestingly, Panama is well-known for its cocoa consumption, and its population has better health and lower incidence of heart disease.

Cocoa comes from beans produced by the Theobroma Cacao tree and contains many beneficial components [RRR]:

  • Polyphenols – plant-derived compounds that protect against bacteria and UV rays. The most abundant polyphenols in cocoa are flavonoids, catechins, and epicatechins.
  • Theobromine – plant-derived compound that has many important functions in heart, respiratory, and mouth health.
  • Minerals – the most abundant minerals are magnesium, copper, and iron, all of which are important in overall health and body function.

Mechanisms of Action

Flavanols (a class of flavonoids) present in cocoa increase the production of nitric oxide (NO) by blood vessels (endothelial cells), which leads to widening of blood vessels, improving their function.

Cocoa exerts its antioxidant properties due to flavanols, which decrease the production of free radicals and, therefore, prevent the destruction of fats in the blood [R].

Epicatechin and catechin cross the blood-brain barrier and localize in certain areas of the brain, therefore providing protection to the brain and improving cognitive function [R].

Flavanols also slow the digestion and absorption of carbohydrates, which balances glucose levels in the body [R].

Health Benefits of Cocoa

1) Cocoa Lowers Blood Pressure

Consumption of cocoa has been proven to lower blood pressure [R].

A study of 15 healthy people showed that the higher the concentration of flavanols, the greater the effect of cocoa on reducing blood pressure. Those who consumed dark chocolate, which has a high concentration of flavonols, saw a much more significant impact than those who consumed white chocolate (without flavonols) [R].

A meta-analysis showed that those who consumed high amounts of flavanols saw a greater reduction in blood pressure than those who consumed little to no flavanols [R].

2) Cocoa Prevents Oxidative Stress damaging cells

Polyphenols in cocoa are antioxidants that prevent free radicals from damaging cells [R].

Cocoa has been shown to have a higher antioxidant capacity than green and black tea and red wine [RR].

3) Cocoa May Improve Cognitive Function woman-forgetful-fb

Cocoa flavonoids improve brain health and cognitive function through both direct and indirect mechanisms.

Flavonoids play a role in brain health by protecting, enhancing function, and creating new neurons. They can also reverse neuron damage in Alzheimer’s and Parkinson’s diseases [RR].

Flavonoids, mainly catechin and epicatechin, cross the blood-brain barrier and localize in areas of the brain responsible for memory and learning, which is where most neurodegeneration occurs [R].

Some studies (DB-RCT) have shown that acute consumption of cocoa improved working memory in healthy adults [RR].

A pilot study on 4 healthy young adults showed that cocoa flavanols also increase blood flow in the brain [R].

4) Cocoa May Prevent Heart Disease dc-Cover-ur8ogei3nb0t5ib4l76k5ugmk1-20160710122803.Medi

The flavonoids present in cocoa decrease blood clotting (platelet activity and accumulation), therefore preventing the formation of blockages within blood vessels [RR].

A meta-analysis suggested that the consumption of cocoa can reduce the risk of developing high blood pressure (hypertension), lower blood pressure, and reduce the risk of heart disease [R].

A review showed that daily consumption of cocoa can increase nitric oxide (NO) circulation in the bloodstream and improve endothelial function [R].

5) Cocoa Enhances Mood 10-Ways-to-Feel-Energized-All-Day-Long-1

A pilot study on 48 healthy men and women revealed that consumption of cocoa enhances mood [R].

A review of several studies also showed the effects of chocolate on mood. Based on the evidence collected, cocoa and chocolate are effective in enhancing mood as well as relieving mental fatigue [R].

6) Cocoa Reduces Constipation healthy-intestine

Cocoa husk is rich in dietary fiber, which helps keep the colon healthy.

A study (DB-RCT) on 48 constipated children revealed that cocoa, mainly cocoa husk, reduces constipation. Those that received the cocoa supplement reported quicker bowel movements, and fewer hard stools, compared to placebo [R].

A single-blind study of 44 healthy men and women suggested that regular consumption of cocoa results in a healthier bowel. Participants who consumed two servings of cocoa a day had faster, more frequent bowel movements, as well as softer stools [R].

7) Cocoa Reduces Chronic Fatigue Syndrome get-energized

A study (DB-RCT) showed that daily consumption of high concentrations of cocoa polyphenols reduced chronic fatigue syndrome, compared to placebo [R].

8) Cocoa May Treat Brain Disorders optic-neuropathy

Increased reactive oxidative species (ROS) play a role in the onset of brain disorders.

Due to the antioxidant properties of polyphenols, consumption of cocoa reduced the production of ROS, potentially protecting against neurodegenerative diseases such as Alzheimer’s and dementia [R].

A pilot study also showed that catechins and epicatechins in cocoa prevent the toxicity and death of brain cells in rats [R].

9) Cocoa May Reduce Obesity  obese_man_800

A study found that rats who were fed cocoa had less visceral fat. This may be due to the ability of cocoa to decrease the production of fats [R].

Another study showed that cocoa consumption in male mice reduced weight gain and the absorption of fat from the diet. Cocoa also reduced inflammation associated with obesity as well as improved insulin resistance [R].

10) Cocoa Is Anti-Cancer Stop-Cancer

Ornithine decarboxylase (ODC) is an enzyme present in normal cells that can lead to cancer if in excess. Cocoa flavanols and procyanidins reduce ODC activity, therefore reducing the risk of developing tumors, and can also kill colon cancer cells [R].

A pilot study revealed that cocoa also inhibits the growth and reproduction of prostate cancer cells, but not the growth of normal cells [R].

Moreover, a review showed that the antioxidant and anti-inflammatoryproperties of cocoa play a role in reducing the overall risk of cancer [R].

11) Cocoa Reduces Bad Cholesterol

A study (DB-RCT) on 48 people at-risk for heart disease and another study (DB-RCT) on 25 people with normal or slightly high cholesterol showed that consuming cocoa powder on a regular basis decreased LDL (bad) cholesterol and increased HDL (good) cholesterol [RR].

12) Cocoa Improves Diabetes and Insulin Resistance  blood-check-banner

shown that consumption of polyphenols can improve diabetes. Cocoa polyphenols, especially from dark chocolate, improve glucose breakdown, reduce blood pressure, and improve insulin resistance [RR].

A study on 10 diabetic patients revealed that consumption of cocoa counteracts blood vessel dysfunction caused by diabetes and improves endothelial function [R].

13) Cocoa Protects the Skin Top-10-Foods-That-Protects-Your-Skin-from-the-Sun

The antioxidant properties of cocoa flavonols play an important role in skin health.

A study (DB-RCT) on 24 healthy women who consumed high amounts of cocoa flavanols concluded that cocoa flavanols provide protection from UV rays, improve blood circulation, and hydrate the skin making it softer and less scaling [R].

Another study found that cocoa flavanols improve blood circulation and increase oxygen concentration in the skin [R].

Another study (DB-RCT) on 11 smokers showed that the consumption of flavanols can reverse skin damage caused by smoking [R].

14) Cocoa Protects the Teeth  welcome_image_2

A review and pilot study on human molar showed that theobromine, present in cocoa, protects the teeth (tooth enamel) [RR].

15) Cocoa Helps the Lunglungs-diagram-120926

A review showed that theobromine relieves coughing in humans and guinea pigs, with less side effects that other remedies [R].

A review and a pilot study on asthma patients showed that theobromine can improve lung function (dilation of the bronchioles) [RR].

16) Topical Cocoa may Help Heal Wounds Anti-Aging-Debunked-1-1038x560

Cocoa has long been used as a remedy for skin conditions such as burns and cuts. While there is not a lot of evidence for the topical use of cocoa products, a review of several studies showed that it promoted the regeneration of skin cells in pigs [RR].

Cocoa also disinfects skin wounds and protects against harmful UV rays [R].

17) Cocoa Treats Copper Deficiency due to Tube Feeding

A retrospective study on patients having long-term tube feeding showed that their copper deficiency was successfully treated with cocoa [R].

A similar study revealed that cocoa restored and maintained normal copper levels in deficient patients [R].

18) Cocoa Reduces Negative Effects of Magnesium Deficiency 

A diet low in magnesium can result in magnesium deficiency, which produces adverse symptoms, such as a loss of muscle mass.

Cocoa is rich in magnesium. A pilot study on rats revealed that cocoa can increase magnesium levels and improve the symptoms of its deficiency [R].

Cocoa Butter

Cocoa butter is the fat extracted from cocoa beans. Some of its components include the amino acidsarginine and leucine, fatty acids, such as oleic, stearic, and palmitic acids, theobromine, and caffeine, among others [R].

Cocoa butter doesn’t contain the polyphenols and, therefore, doesn’t have the same effect as cocoa.

19) Cocoa Butter Reduces Cough Depositphotos_6301020_m

Cocoa butter is widely used to treat a cough, in combination with warm milk and honey. Cocoa butter can also be rubbed on the chest and back to reduce coughing.

Several studies have shown that theobromine and caffeine, two active components of cocoa butter, are effective in reducing cough [RR].

20) Cocoa Butter May Reduce VLDL Cholesterol Cholesterol

VLDL cholesterol is the most unhealthy cholesterol-carrying protein as it contains the highest amount of fat (triglycerides). A pilot study revealed that rats that received cocoa butter had less VLDL cholesterol. This decrease can be attributed to a decrease in fat production or an increase in its removal [R].

21) Cocoa Butter May Improve the Skin
