Can a Diet Of Chocolate and Olive Oil Be The Answer to a Lower Risk Of Heart Disease


Heart disease can cause symptoms such as heart attacks and even heart failure. Now experts have revealed an unusual combination of dark chocolate and olive oil is eaten together could protect people against the condition.

A daily bar of dark chocolate could protect against heart disease – but it has to be enriched with olive oil, experts have said. Experts found the food boost the number of cells responsible for repairing blood cells to circulate in the blood.

This prevented the blood vessels from hardening and narrowing – a process called atherosclerosis. The cells are called endothelial progenitor cells (EPCs), stem cells that are important in vascular healing.

“A healthy diet is known to reduce the risk of cardiovascular disease,” said Dr Rossella Di Stefano, a cardiologist at the University of Pisa, Italy.

“Fruits and vegetables exert their protective effects through plant polyphenols, which are found in cocoa, olive oil, and apples.

“Research has found that the Italian Panaia red apple has very high levels of polyphenols and antioxidants.

“We found that small daily portions of dark chocolate with added natural polyphenols from extra virgin olive oil was associated with an improved cardiovascular risk profile.

“Our study suggests that extra virgin olive oil might be a good food additive to help preserve our ‘repairing cells’, the EPC.”

Experts looked at whether chocolate enriched with olive oil or apple extract prevented atherosclerosis in people at risk of heart disease. Olive oil is a key part of the Mediterranean diet. The study involved 26 volunteers of which 14 men and 12 women with at least three cardiovascular risk factors including smoking, high cholesterol, high blood pressure or a family history of cardiovascular disease.

They were given 40g of dark chocolate daily for 28 days.

For two weeks the chocolate contained ten per cent extra virgin olive oil and for the next fourteen days, it contained 2.5 per cent Panaia red apple. Progression of atherosclerosis was assessed by metabolic changes including blood fats, blood pressure, and levels of circulating endothelial progenitor cells (EPCs).

After 28 days, the researchers found that the chocolate enriched with olive oil was associated with significantly increased EPC levels compared to both the start and those eating the apple-enriched chocolate.
