The Effect of High Polyphenol Extra Virgin Olive Oil on Blood Pressure and Arterial Stiffness in Healthy Australian Adults: A Randomized, Controlled Cross-Over Study

Extra virgin olive oil (EVOO) is suggested to be cardioprotective, partly due to its high phenolic content. We investigated the effect of extra virgin high polyphenol olive oil (HPOO) versus low polyphenol olive oil (LPOO) on blood pressure (BP) and arterial stiffness in healthy Australian adults. In a double-blind, randomized, controlled cross-over trial, 50 participants (age 38.5 ± 13.9 years, 66% female) were randomized to consume 60 mL/day of either HPOO (360 mg/kg polyphenols) or LPOO (86 mg/kg polyphenols) for three weeks. Following a two-week washout period, participants crossed over to consume the alternate oil. Anthropometric data, peripheral BP, central BP and arterial stiffness were measured at baseline and follow up.

Longer intervention studies and/or higher doses of EVOO polyphenols are warranted to elucidate the potential effect on DBP and arterial stiffness.

Australian Olive Industry Figures for Harvest, Table Olive & Oil Production, Imports & Exports till 2019

Introduction The renaissance of the Australian olive industry is entering its second decade. During the last 10 years, the Australian industry has grown solidly from a cottage industry to a technically sophisticated industry that is increasingly export focus. Over this time, the quality of Australian olive oil has consistently improved, and production efficiencies increased, to…

Australian Extra Virgin Olive Oil Provenance Project

Summary European experience has shown that marketing advantage leading to higher prices in extra virgin olive oils can be achieved by emphasising the healthfulness and taste differences attributable to the region that the olive was grown. A pilot-study involving a collaborative effort between olive growers from the Fleurieu Peninsula region of South Australia and South East Queensland using the variety Frantoio showed that the oils from the two regions, harvested at the same ripeness, and processed identically could be reliably differentiated (>90% accuracy) by knowing the relative proportions of the types of polyphenols in the oils.
