Una nuova study pub­lished in Food Chemistry shows that adding phenol-​rich olive oil to break­fast suc­cess­fully low­ers the inflam­ma­tion linked to meta­bolic syn­drome.

L'infiammazione è associata alla sindrome metabolica, una condizione sempre più comune caratterizzata dalla presenza di tre delle seguenti patologie in un individuo: obesità (in particolare grasso addominale), pressione alta, basso livello di colesterolo HDL "buono", glicemia alta a digiuno e un alto livello di trigliceridi. Se non trattata, la sindrome metabolica può scatenare diabete, ictus e malattie cardiache.

Forty-​nine patients with meta­bolic syn­drome added 40 ml of high‑, medium- or low-​phenol vir­gin olive oil to their break­fast. The high-​phenol olive oil (398 parts per mil­lion) break­fast neu­tral­ized pro-​inflammatory gene expres­sion in patients while reduc­ing pro-​inflammatory cytokines in blood plasma. The result was an over­all lower level of post-​meal inflam­ma­tion.

Phenols — phy­to­chem­i­cals found in plant-​based foods such as olives, cof­fee, tea, and choco­late — have been enjoy­ing the nutri­tional lime­light as an increas­ing num­ber of health-​related ben­e­fits are revealed. While the lion’s share of stud­ies to date focus on their anti-​oxidant ben­e­fits, grow­ing evi­dence shows that phe­nols also reduce inflam­ma­tion.

Chronic low-​grade inflam­ma­tion pre­cedes and pre­dicts the onset of dia­betes in adults with meta­bolic syn­drome and researchers believe it plays a sim­i­lar role in car­dio­vas­cu­lar dis­ease. It is esti­mated that over 30 per­cent of all adults in the USA have meta­bolic syn­drome, a phe­nom­e­non seen in another west­ern coun­tries and quickly spread­ing to devel­op­ing coun­tries includ­ing India, China and Brazil.

This study adds valu­able infor­ma­tion on under­stand­ing how phe­nols reduce inflam­ma­tion by mod­u­lat­ing cell sig­nal­ing path­ways and sug­gests that a break­fast that includes phenol-​rich olive oil helps alle­vi­ate inflam­ma­tion asso­ci­ated with meta­bolic syn­drome and related dis­eases.
