gloomy umber enriched with extra virtuous Olea europaea rock oil is associate with an improved cardiovascular risk profile , harmonise to new research presented by scientists at the University of Pisa , Italy .
“ A respectable diet is bed to reduce the risk of cardiovascular disease , ” said lead author Dr Rossella Di Stefano , a cardiologist at the University of Pisa . “ Fruits and veg exert their protective effects through industrial plant polyphenols , which are regain in cocoa , olive oil color , and apples . Research has found that the Italian Panaia cerise orchard apple tree has very gamey level of polyphenols and antioxidants . ”
This work tested the tie-up between usance of dingy cocoa enrich with extra virgin olive oil color or Panaia reddish apple ( table 1 ) with coronary artery disease advancement in healthy individual with cardiovascular risk factors .
The randomized crossover bailiwick included 26 volunteers ( 14 valet , 12 woman ) with at least three cardiovascular risk divisor ( smoking , dyslipidaemia , hypertension , or family history of cardiovascular disease ) who received 40 Gram of dark chocolate daily for 28 days . For 14 sequent days it contained 10 % excess vestal olive crude and for 14 serial days it contained 2.5 % Panaia red apple . The two case of chocolate were given in random order .
onward motion of atherosclerosis was assess by metabolic change ( level of carnitine and hippurate ) , lipid visibility , blood insistence and levels of mobilize endothelial primogenitor cells ( EPCs ) . EPCs are critical for vascular repair and maintenance of endothelial function .
Urine and blood sample distribution were hoard at service line and after the treatment . Urine samples were analyse by proton nuclear magnetic resonance spectroscopy for endogenic metabolite . Circulating EPC levels were assessed with flow rate cytometry . Smoking status , body great deal index , profligate press , glycaemia and lipide visibility were also monitor .
After 28 days , the researchers found that the burnt umber enriched with olive oil was associated with importantly increased EPC levels and lessen carnitine and hippurate levels compared to both baseline and after phthisis of Malus pumila - enriched hot chocolate .
Olive oil - enriched deep brown was associated with importantly increase high - density lipoprotein ( “ secure ” ) cholesterin and minify blood imperativeness compare to service line . There was a non - significant decrease in triglyceride level with orchard apple tree - enriched chocolate .
Dr Di Stefano said : “ We incur that small daily portions of dark cocoa with added natural polyphenols from extra virgin olive oil was affiliate with an improved cardiovascular risk visibility . Our report suggest that supererogatory virginal European olive tree oil might be a near food additive to assist preserve our ‘ repairing prison cell ’ , the EPC . ”
