Chocolate enriched with olive oil may prevent heart disease, new research reveals.
Eating the possibly hard-to-stomach combination every day boosts so-called ‘good’ cholesterol levels and lowers blood pressure, a study found.
It also significantly raises endothelial progenitor cell (EPC) levels, which are critical for blood vessel repair and function, the research adds.
Lead author Dr Rossella Di Stefano from the University of Pisa, said: ‘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.’

How the study was carried out
Researchers from the University of Pisa analysed 26 healthy people with at least three of the following heart disease risk factors: smoking, elevated lipid levels in the blood, high blood pressure or a family history of the condition.
The study’s participants received 40 grams of dark chocolate every day for 28 days.
For 14 consecutive days, the chocolate contained 10 per cent olive oil. For the remainder of the trial’s duration it included 2.5 per cent of the Italian red apple Panaia.
Dr Stefano said: ‘Research has found that the Italian Panaia red apple has very high levels of polyphenols and antioxidants.’
Urine and blood samples were collected before and after the study.
Chocolate boosts ‘good’ cholesterol
Results reveal that eating chocolate enriched with olive oil significantly increases EPC levels.
EPC is critical for blood vessel repair and function. Low levels are associated with thick, hard arteries, which are linked to heart attacks and stroke.
Eating chocolate with olive oil also increases ‘good’ cholesterol and lowers blood pressure.
Dr Stefano said: ‘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.’
The findings were presented at the European Society of Cardiology congress in Barcelona.
