What if the best treatment for high blood pressure was a delicious food - or drink?!

There’s so much to learn from our ancestors. They used to live in harmony with Mother Nature. Their food was never artificial, they had the privilege of breathing clean air and their sleep was not interrupted by stressful jobs or sky-high bills. That’s why chronic and degenerative diseases are a relatively new issue in the history of mankind.

Cocoa was a commodity in Mesoamerica before the Spanish conquest. The cocoa bean was even considered a currency at that time and Spaniards were amazed by its delicious taste upon their arrival in America. Being fully aware of the therapeutic properties of cocoa, Aztecs used it to treat several ailments in mixtures with oils from trees. In 1944, a group of researchers found that the Kuna Indians from the San Blas Islands of Panama drank 3 to 4 cups of cocoa a day and had lower blood pressure than continental Kuna people who no longer drank cocoa. Today, several clinical trials have proved that cacao can actually lower blood pressure, although most chocolate products available in the market are not recommended for this purpose.


Chocolate: friend or foe?

High blood pressure is a risk factor for cardiovascular disease. Medicine and lifestyle changes, such as shifting to balanced diet and maintaining a healthy weight, are necessary to control blood pressure. While a low sodium diet is usually recommended by physicians, I cannot stress enough the importance of incorporating polyphenols to your diet. Cocoa is rich in epicatechin and catechin flavonols that prevent oxidation of the endothelium – the internal lining of the blood vessels – and promote vasodilation by increasing nitrous oxide production and blocking angiotensin-converting enzyme, all of which play an important role in treating hypertension, heart failure and angina. This means cocoa nutrients have the therapeutic activity of three or more different drugs!

If you are a chocolate lover with high blood pressure you should definitely consider eating dark chocolate with a high percentage of cacao (above 70%). In fact 50 g of cocoa per day can help reduce systolic blood pressure by 3.7 mmHg and diastolic blood pressure by 2.7 mmHg. Some studies suggest lower cacao contents in chocolate work but unfortunately, many chocolate bars and other products have minimum cocoa content and are rich in sugar and saturated fat. Moreover, as their cacao content is much lower than 50%, they won’t have such healthy effect and could contrarily contribute to cardiovascular risk.

It’s not a myth! Chocolate is good for you

The Zutphen Elderly Study taught us a lot about habitual cocoa intake. This study assessed cocoa consumption of 470 elderly men as well as their blood pressure and causes of death over a period of 15 years. Men who regularly took cocoa were found to have lower blood pressure and were less likely to die from cardiovascular diseases. Similarly, the Iowa Women’s Health Study evaluated the incidence of cardiovascular diseases and causes of death of more than 34,000 women during 16 years of follow up. Eating chocolate was specifically associated with a reduced risk of death from cardiovascular diseases again.

Moreover, a German study in more than 19,000 participants found that consumption of as little as 6 grams of chocolate per day reduced the risk of heart attacks and stroke by 40%, partly through lowering blood pressure. Some other studies have confirmed chocolate lowers the risk of heart failure and plaque buildup in the coronary arteries.

Benefits beyond the heart

Chocolate is also able to:

·   - Increase HDL cholesterol in Type 2 diabetes patients and protection of LDL cholesterol against oxidation (see how to tacklehigh cholesterol from every angle)
- Enhance positive mood and reduced anxiety
- Increase blood flow to the brain, improving oxygenation 
- Modulate intestinal inflammation
- Prevent blood clots (aspirin-like effect)

Potential health benefits

- Cancer prevention and inhibition of cancerous cells' growth (see how green tea protects against cancer)
- Skin care
- Prevention and control of chronic inflammatory diseases (read about lessening the severity of autoimmune diseases)
- Anti-diabetic effects


There you go! As a final remark, I’d like to say you can always enjoy the good things of life without regrets. Just find good quality chocolate and have it or drink it daily – and always remember to share it with your loved ones.  I think the world would simply be a better place with more dark chocolate and less sugar.
