The Claim
Daily consumption of either extra-virgin olive oil or refined olive oil at a dose of 30 mL/day for six months reduces the plasma amyloid-β 42/40 ratio in adults with mild cognitive impairment, indicating an alteration in amyloid processing and clearance.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Eating either extra-virgin or regular olive oil (about 2 tablespoons a day) for 6 months lowers a blood marker called the amyloid-beta 42/40 ratio in adults with mild memory problems. This marker is linked to Alzheimer's plaques, and the reduction shows that olive oil affects how the brain handles and removes this protein.
See the scientific wording
Daily consumption of either extra-virgin olive oil or refined olive oil (30 mL/day) for 6 months reduces the plasma amyloid-β 42/40 ratio in adults with mild cognitive impairment, suggesting altered amyloid processing and clearance.
Eating olive oil every day for six months changes the way the body handles a sticky protein called amyloid-beta. It makes the body produce less of the harmful form (Aβ42) and also helps the body break down and remove this protein more efficiently. This lowers the amount of Aβ42 in the blood compared to another form, Aβ40.
What the research says
1 studyThe study found that eating a small amount of olive oil every day for six months lowered the levels of a harmful protein in the blood, which is a sign that the brain might be better at clearing these sticky proteins.
