Do olives offer same benefits as their oil?

DEAR DR. BLONZ: We all know how healthy extra-virgin olive oil is for us.
Do we get the same health benefit from eating olives?

– J.T., Olean, N.Y.

DEAR J.T.: Olives are quite bitter coming off the tree. When used as eating olives, they need to undergo a curing process to remove this bitterness. The process usually involves a salt solution or one using lye (sodium hydroxide). Both processes leave the olives high in sodium: 15 grams of olives (three to five olives, depending on size) contains about 115 milligrams of sodium. In pimento-stuffed olives, the sodium content can be double. When olives are used for oil, the harvested olives go directly to the presses without treatment. The fatty-acid profile and types of phytochemicals are similar in eating olives and extra-virgin olive oil, but you would have to eat many olives to equal a comparable amount of oil.

A tablespoon of olive oil, for example, contains 120 calories. It would take about 22 large, black-pitted olives to match that amount of oil, but 22 olives contains 644 milligrams sodium. I enjoy eating olives, and there are countless varieties and flavors, but keep in mind that it’s a high-sodium food. If you are interested in learning more about olives, the University of California (Davis) Cooperative Extension offer an excellent visual of different types.
