A study published in the journal Nutrition Research looked at whether olive oil intake, fish consumption, and omega-3 supplementation would increase the levels of red blood cell oleic acid and the omega-3 index of a person. This study was conducted by a team of researchers from the U.S. and Italy.
  • The research team looked at 461 participants from the Gruppo Italiano per lo Studio della Sopravvivenza nell'Infarto Miocardico–Heart Failure (GISSI-HF) study.
  • The participants took either an olive oil placebo or an omega-3 supplement every day for three months. They also reported their usual olive oil and fish intakes.
  • Before and after the intervention, the researchers collected red blood cell samples from the participants to measure their omega-3 index.
  • They found that red blood cell oleic acid levels reflected the participants’ olive oil intake, while omega-3 levels reflected fish consumption and omega-3 supplementation.
  • After treatment, the omega-3 index of the participants who took the omega-3 supplement increased.
  • At three months, more participants reached the proposed target omega-3 index level of eight to 12 percent.
In conclusion, the findings suggested that olive oil consumption could increase red blood cell oleic acid levels, while fatty fish intake and omega-3 supplementation could increase omega-3 levels.
