Olive Oil Polyphenols Boost HDL Function
the MPR take:
Numerous studies have shown that olive oil can be beneficial against cardiovascular risk factors, especially by increasing cholesterol content in high-density lipoproteins (HDL). Is it the polyphenols in the olive oil? Forty-seven healthy male volunteers were given 25mL of polyphenol-poor (2.7mg/kg) or polyphenol-rich (366mg/kg) raw olive oil in 3-week intervention periods, preceded by 2-week washout periods in a randomized, crossover, controlled trial. The men consuming the polyphenol-rich olive oil had significantly improved HDL cholesterol vs. the polyphenol-poor group (3.05% vs. −2.34%, respectively; P=0.042). The polyphenol-rich olive oil increased HDL size, promoted greater HDL stability reflected as a triglyceride-poor core, and enhanced the HDL oxidative status. This is the first study to find first-level evidence of an improvement in HDL function with polyphenol-rich olive oil, note the study authors.
Objective- Olive oil polyphenols have shown beneficial properties against cardiovascular risk factors. Their consumption has been associated with higher cholesterol content in high-density lipoproteins (HDL). We, therefore, assessed whether polyphenol-rich olive oil consumption could enhance the ...
