Study Suggests Olive Oil Helps Prevent Arterial Disease, Pomace Oil Might Worsen It

Olive oil consumption is associated with benefits for the prevention of peripheral arterial disease, while pomace oil could promote its development.

New evi­dence shows that daily con­sump­tion of extra vir­gin olive oil offers some­thing of a shield against periph­eral arte­r­ial dis­ease (PAD).

A newly pub­lished research on the sub­ject led by the Spanish University of Jaén also hints at the pos­si­bil­ity that pomace oil could pave the way to PAD.

The research was con­ducted by a cross-sec­tional analy­sis car­ried out in 4,330 par­tic­i­pants in a wide trial involv­ing vol­un­teer recruit­ment cen­ters and obe­sity sup­port groups through­out Spain and known as PREDIMED-Plus, con­sid­ered the largest Spanish trial on nutri­tion.

According to the study pub­lished by the mag­a­zine Atherosclerosis, the goal of the sci­en­tists has been to under­stand the asso­ci­a­tion between the ankle-brachial index (ABI), con­sid­ered a PDA marker, and olive oil and olive pomace oil con­sump­tion.

PREDIMED-Plus, a trial of lifestyle mod­i­fi­ca­tion in indi­vid­u­als with over­weight or obe­sity har­bor­ing the meta­bolic syn­drome, has the ambi­tion to doc­u­ment the health ben­e­fits of olive oil and the Mediterranean diet.

Consumption of any cat­e­gory of olive oil and olive pomace oil was assessed through a val­i­dated food-fre­quency ques­tion­naire,” explained the authors of the research intro­duc­ing their results, and mul­ti­vari­able lin­ear regres­sion mod­els were fit­ted to assess asso­ci­a­tions between olive oil con­sump­tion and ABI.”

Among 4,330 par­tic­i­pants,” wrote the researchers, the high­est quin­tile of total olive oil con­sump­tion (sum of all cat­e­gories of olive oil and olive pomace oil) was asso­ci­ated with higher mean val­ues of ABI”. Still, logis­tic mod­els com­par­ing the con­sump­tion of the dif­fer­ent olive oil types and olive pomace oil revealed an inverse asso­ci­a­tion between vir­gin olive oils con­sump­tion and the like­li­hood of a low ABI, while con­sump­tion of olive pomace oil was pos­i­tively asso­ci­ated with a low ABI.

In this way,” the University note reads, the researchers con­cluded that, in patients with high car­dio­vas­cu­lar risk, the con­sump­tion of olive oil is asso­ci­ated with ben­e­fits for the pre­ven­tion of periph­eral arte­r­ial dis­ease, the oppo­site of the con­sump­tion of pomace olive oil, which could pro­mote its devel­op­ment.”

Those find­ings con­firm the hypoth­e­sis of pre­vi­ous stud­ies that hinted at a pos­si­ble pos­i­tive effect of the Mediterranean diet on PAD patients.

PAD is a pro­gres­sive dis­ease that brings to the nar­row­ing of the arter­ies with con­se­quent impact on the blood flow, espe­cially on human limbs, but it can also impact on heart and brain.

A healthy diet is con­sid­ered essen­tial to a suc­cess­ful recov­ery from the con­di­tion which often fol­lows ath­er­o­scle­ro­sis.
