One of the amazing benefits of the moderate consumption of dark chocolate is its ability to lower blood pressure [1]. It is also more enjoyable and cheaper way of lowering blood pressure than some medications.

The benefits of dark chocolate are greater in people who are suffering from hypertension. Many studies suggest that the flavanols present in this dessert are more effective when a person’s blood pressure is high. The flavanols stimulate the lining of the arteries to produce Nitric Oxide. One of the functions of NO is to lower resistance to blood flow and therefore reduces hypertension.

While vegetables, fruits, and natural teas are great sources of antioxidants, the cocoa bean content in dark chocolate is considered to be more powerful.

High consumption of this chocolate can improve abstract reasoning, working memory, scanning and tracking and visual-spatial awareness [2].

The consumption of flavanols-rich cocoa helps in increasing blood flow to the brain and may be beneficial in health conditions with reduced brain blood flow, such as stroke and dementia. According to a 2009 study published in Journal of Nutrition, their participants who consumed chocolate, wine, or tea had better test results and lower incidence of poor cognitive performance than those who did not. In the elderly, including flavonoid-rich foods in their diet can result in better performance in several cognitive abilities.

3. Huge Source of Antioxidants

Among the types of chocolates, dark chocolate is considered to be the healthiest. It contains high amounts of many powerful antioxidants. It is filled with catechins, polyphenols, flavanols, and theobromine that are all beneficial to the body. Antioxidants help the organs perform well and slow down the process of aging. Foods rich in antioxidants can reduce the risk of various heath conditions, including cancer.

A study conducted by the Hershey Co. published in Chemistry Central Journal compared the flavanol, polyphenol, and antioxidant activity content of cocoa powder and dark chocolate to antioxidant-rich fruits or “Super Fruits” like blueberry, acai, pomegranate and cranberry.

The researchers found that the flavanol in cocoa powder was significantly greater than other fruits used. The antioxidant capacity of dark chocolate was also higher than all super fruits except pomegranate [3].

4. Good for the Heart

One of the health benefits of dark chocolate is it helps in fighting against various cardiovascular diseases. The regular consumption of cocoa can improve blood flow to the heart and brain. In addition to the antioxidant properties, dark chocolates flavanols also lower blood pressure and assist in making blood platelets less sticky and able to clot. This ability lowers the risk of blood clots and stroke.

The compounds in dark chocolate are protective against the oxidation process of LDL. This results in less cholesterol to block the arteries, lowering the risk of heart diseases. A study published in International Journal of Cardiology showed that the consumption of flavonoid-rich dark chocolate significantly improved blood flow to the heart in adults regardless of the changes in oxidative stress parameters, blood pressure, and lipid profile.

Another study of 470 elderly men has found that cocoa can lower the risk of cardiovascular death by 50% over a 15 year period.

There is still not enough evidence that flavonoids truly combat cancer, but it can prevent various types of cancer in a pleasurable way.

Another study published in Southern Medical Journal observed the effects of dark chocolate on 28 healthy subjects. It was found that one week of dark chocolate consumption enhanced lipid profiles, reduced inflammation in women, and decreased platelet reactivity for both men and women [5].

The results also showed that:

  • Three-week consumption of dark chocolate increased good cholesterol.
  • Polyphenols in dark chocolate may be involved in the regulation of cholesterol.
  • Seven-day consumption of regular dark chocolate reduced LDL cholesterol by 6% and increased HDL cholesterol by 9%.

7. Prevents Depression

One of the health benefits of dark chocolate is the ability to prevent depression. It has theobromine, a chemical similar to caffeine, which can boost energy levels and excitability. The anandamide chemical in dark chocolate is also an excellent mood and energy booster without cardiovascular damage and addiction. These chemicals, including tryptophan, can help you feel calm.

Dark chocolate also contains phenethylamine, a chemical that is metabolized into serotonin. Serotonin, also called happy hormones, is one of chemicals that are responsible for your mood.

In addition to dark chocolate’s anti-inflammatory properties, coca can also provide positive impacts on certain cells that produce antibodies [6]. Antibodies are the Y-shaped protein produced by plasma cells and are used by the immune system to neutralize pathogens like viruses and bacteria.
