Olive oil – it just gets better and better.
My husband loves olive oil. He loves it so
much he adds a dollop of extra virgin olive oil to all his salads, his mash and
even his corn on the cob. So much better than butter he declares.
Well, it turns out he may be right.
Olive oil contains a substance called
oleocanthal, which is a mouthful in itself. Oleocanthal is a phenol and studies
suggest it may have a neuroprotective effect for the brain by enhancing the
removal of beta amyloid from the brain.
So this, rather then the fact that olive oil
is what is called a monsaturated fat, is what makes it so good for us.
Amal Kaddoumi and his research colleagues undertook
mouse studies that examined how oleocanthal boosts the production of two
proteins, key enzymes critical to removing beta amyloid from the brain. This
might go a little way to help explain why following a Mediterranean style diet
rich in olive oil is linked to a lower incidence of Alzheimer’s disease.
My husband will be delighted.
