Drinking a hot cup of cocoa may be as healthy as it is delicious as the unsweetened raw cocoa powder is rich in antioxidants. The top health benefits of cocoa include its ability to lower blood pressure, prevent the risk of cardiovascular diseases, and aid in weight management. The potent polyphenols in cocoa also help improve blood flow to the brain.

What is Cocoa?

Cocoa is a powder made from roasted, husked, and dried cacao beans, which are the fermented seeds of the cacao tree. The cacao tree stands about 12-25 feet tall and grows naturally in tropical climates. The fruits, or the cacao beans, are actually pods filled with sweet pulp enfolding a cluster of about 20-40 cacao seeds. The Latin name for cacao beans is Theobroma cacao, which translates to “Food of the Gods”. These ground beans (cocoa liquor or cocoa mass) also contain cocoa butter, a non-dairy, naturally occurring fat present in cacao beans. About 50-60 percent of cocoa liquor consists of cocoa butter.

You may have seen cacao powder as well as cocoa powder in the supermarket aisles and wondered about the difference. Cacao powder refers to the product made from beans that have not been roasted and contain a higher number of antioxidants as compared to cocoa powder. Commercially available chocolates and cocoa-products may not be rich in the original beneficial flavonols of cacao beans since they can be get destroyed by over-processing. In this article, we look at the health benefits of dry, unsweetened cocoa powder.

Nutrition Facts

According to USDA, a tablespoon of unsweetened cocoa powder contains 12 calories, 3.1 grams of carbohydrates, and 1 gram of protein. Cocoa powder is a rich source of polyphenols such as catechins, flavonol glycosides, anthocyanins, and procyanidins. It also contains stimulants like theobromine and caffeine. In addition to this, cocoa powder contains minerals like magnesium, copper, and iron.

Cocoa Health Benefits

To obtain the benefits of cocoa, it is important to consume the correctly sourced product. A small piece of dark, unsweetened, or unprocessed chocolate may be considered to add some flavor and health to your diet. Let’s look at some of the major health benefits of cocoa.

May Lower High Blood Pressure

Researchers found that consuming cocoa-containing foods helped lower blood pressure levels in a small sample size of participants. A meta-analysis also revealed a positive change in the systolic and diastolic blood pressure as a consequence of consuming cocoa-based products as compared to an intake of black or green tea for seven days. These favorable changes are attributed to the presence of antioxidants in it that stimulate the production of nitric oxide, which helps keep blood vessels relaxed.

Antioxidant Capacity

A comparative research study published in 2003 in the Journal of Agricultural and Food Chemistry has made it evident that cocoa exhibits higher antioxidant activity than black tea, green tea, and red wine. Antioxidants help neutralize the oxygen-based free radicals that are present in the body.

Cocoa powder is also abundant in phenolic phytochemicals and flavonoids. Zinc, present in it, helps protect against oxidative stress, which is a major cause behind accelerated aging.

May Improve Brain Health

Cocoa contains a high amount of flavonoids, like flavonol. Research led by Dr. Norman K. Hollenberg has suggested that flavanol may aid in maintaining a healthy brain. These neuroprotective benefits could also have favorable effects on learning and memory functions. The findings have advocated that the consumption of cocoa-based products enhances the flow of blood to the brain and they have provided evidence of the therapeutic potential for curing vascular disorders.

May Lower Risk Of Heart Attacks & Stroke

Cocoa powder is rich in flavonoids – namely, procyanidin, catechin, and epicatechin, which have antioxidant properties. In moderate amounts, it can help in protecting the cells from damage, while strengthening the heart. It prevents the formation of fatal blood clots, which can lead to stroke or cardiac failure. The flavonoids possess anti-platelet aggregating effects and modulate primary hemostasis, which is the measure of time blood takes to clot. This ultimately helps prevent atherosclerosis and thrombosis.

Balances Cholesterol Levels

A 2004 study shows that cocoa may possess hypoglycemic and hypocholesterolemic effects on both glucose and cholesterol levels, respectively. It helps reduce triglycerides and LDL (bad) cholesterol levels in the body and gives a noteworthy rise to HDL (good) cholesterol levels in the body.

Anticancer Benefits

Cocoa has demonstrated beneficial effects in inhibiting the growth of cancer cells without affecting the growth of normal healthy cells. Studies conducted by a team of researchers in France have provided evidence regarding the chemopreventive and anti-proliferative qualities exerted by the flavonols and procyanidins on colon cancer.

Regulates Blood Sugar Levels

A research study published in the American Journal of Clinical Nutrition suggests that consumption of cocoa powder is effective in improving insulin resistance and glucose metabolism. These mechanisms, in turn, aid in regulating sugar levels in the body. The proanthocyanidins derived from this product may help in inhibiting the cataract formation occasionally induced by diabetes, according to one animal study. The intake of this flavanol-rich bean also has therapeutic potential in improving the vascular function of people with diabetes on various medications.

Relieves Bronchial Asthma

Cacao beans contain xanthine and theophylline, which aid in relaxing bronchial spasms and opening constricted bronchial tubes. This gives it anti-asthmatic properties and is valuable in curing various allergies, including asthma and shortness of breath.

Research published in 2014 in the International Journal of Immunopathology and Pharmacology suggests that unsweetened powder has anti-asthmatic properties as it contains theobromine.

Weight Management

A study has shown the potential benefits of cocoa in preventing high-fat-diet-induced obesity. Its intake helps in modulating lipid metabolism and reducing the synthesis and transport of fatty acids. It also improves thermogenesis, which is the mechanism of heat production in white adipose tissues and the liver. However, remember that if you are consuming cocoa powder in foods and beverages that contain high amounts of sugar and fat, it will be detrimental to weight loss.

Enhances Mood

Consuming cocoa powder has shown antidepressant-like effects on certain physiological processes. Its flavonols help enhance the mood, fight depression, and promote cognitive activities during persistent mental exertion. The presence of the neurochemical phenylethylamine in cocoa also helps in enhancing feelings of contentment and promoting aphrodisiac effects.

Skin Care

Research findings suggest that the consumption of flavonol-rich cocoa helps in decreasing the effects of UV-induced erythema, and reducing skin roughness and scaling. It may also aid in enhancing skin elasticity, hydration, and density. Epicatechin present in cacao aids in increasing the oxygen saturation of hemoglobin, stimulating the healthy flow of blood in the dermal (skin) tissues, and contributing to endogenous photo-protection. It is also used in the preparation of various skincare products.

Neuroprotective Properties

Cocoa has flavonoids, such as epicatechin and catechin, which have been found to have an anti-neurodegenerative effect. In a rat model study conducted by Cho et al., cocoa procyanidins (a type of flavonoid) had a protective effect against oxidative stress, which has strongly linked to the development of neurodegenerative disorders, including Alzheimer’s disease. Further human studies are required to research the potential benefits of this bean against neurodegenerative diseases over time.

Other Health Benefits

  • Speeds up Healing: Cocoa extracts have been trusted for their therapeutic and wound-healing properties in the manufacturing of natural medicinal products.
  • Treats Constipation: According to a study done on pediatric patients, consumption of fiber-rich cocoa products resulted in faster colonic, rectal, and intestinal transit times.
  • Aids in Copper Deficiency: It may be added to the diet to maintain normal levels of copper, as well as a remedy for treating copper deficiency in such conditions.
  • Reduces Chronic Fatigue Syndrome: Cocoa powder has been shown to exert calming effects on people suffering from chronic fatigue as it helps release neurotransmitters like serotonin, anandamide, and phenylethylamine in the brain.
  • Prevents Magnesium Deficiency: The regular consumption of cocoa products may prove beneficial in preventing the adverse effects caused by a diet lacking in magnesium for an extended time.

Uses

Cocoa has been treasured worldwide for its usage in the manufacturing of chocolate and other sweet delicacies. Fermented and dried cocoa beans can be processed to produce a variety of products.

  • Cocoa powder: You get two varieties of unsweetened cocoa powder: dutch-processed and natural. Both kinds are used in baking and cooking. Its most well-known use is to make chocolate, cakes, and a beverage called cocoa or hot chocolate.
  • Chocolate: Cacao beans are roasted, husked, ground, and, depending on the desired product, sweetened and flavored to produce chocolate. Several types of chocolate are produced from cacao beans, including unsweetened chocolate, bittersweet chocolate, semi-sweet chocolate, milk chocolate, and white chocolate.
  • Cocoa butter: It is used to make chocolate as well as a plant-based alternative for gelatin to enhance the flavor and aroma of food. Cocoa butter is also used in soaps and cosmetic products due to its moisturizing properties.
  • Cocoa liquor: It is used, with other ingredients, to produce chocolate.

In addition to cacao beans, the therapeutic utilization of cacao bark, butter, and flowers have also been valued since ancient times for treating various diseases like skin ailments, bowel malfunction, and wounds.

Side Effects

The major side effects of cocoa include:

Caffeine addiction

Cocoa is a source of caffeine and an excessive intake may cause the following:

  • Increased urination, sleeplessness, and irregular heartbeat
  • It can also aggravate the conditions of people already suffering from anxiety disorders
  • Excess caffeine during breastfeeding can result in crankiness and abdominal discomfort in infants
  • It may also worsen the condition of gastroesophageal reflux disease

Note: Avoid use before surgeries to avoid any interference with blood sugar control.

Allergic reactions

Cocoa may cause allergic reactions like the following:

  • Skin reactions
  • Migraine headaches
  • Digestive discomforts (i.e., gas, nausea)

Drug interactions

  • It may interact with certain medications including Clozaril, dipyridamole, ergotamine, phenylpropanolamine, and theophylline, and influence their effects on the body. Ask your doctor or check labels to ensure safe consumption.
  • In addition to this, it may also interact with drugs for asthma, depression, and diabetes.

Caffeine may influence the effects of certain medications prescribed before the diagnostic test associated with the heart. It is generally advised to avoid caffeine-rich beverages or foods such as cocoa before such cardiac examinations. Also, consult your doctor before adding a new type of food, especially one with so many unique compounds, into your diet.

FAQs

How can you tell if the cocoa powder has gone bad?

You can pass the powder through the smell test! If the cocoa powder has gone rancid, it will give an unpleasant odor and can cause digestive problems if consumed.

Cocoa Origin

Cocoa is native to the Amazon region of South America. Historically, it is considered a very important crop in Central and South America. Along with its well-established role in the manufacturing of chocolate, the healing and medicinal benefits of cocoa have been appreciated since the ancient Mayan and Aztec civilizations were ruling.

Its beans were so prized that the native tribes used them as a form of currency. Today, it is produced across the world, with about forty percent of the harvesting done on the South Coast of West Africa, along with Indonesia, Ghana, Brazil, Nigeria, and Cameroon, which contributes to the overall production.
