The life span of an olive tree ranges from 300 to 600 years. Typically, olives are first harvested after 15 years.

Background

  • Olives are a member of the Oleaceae botanical family.
  • Olives are a fruit, known as a drupe that grow on a small tree or shrub.
  • There are over a thousand varieties of olives grown throughout the world, though an estimated 139 varieties account for 85% of olive production around the world.
  • Olives contain oleuropein, a bitter component which requires olives go through a curing/brining process prior to production. These steps make the olives palatable.
  • Olive oil is produced by extracting oil from the pulp of the fruit. There are different extraction processes depending on the type of olive oil being made.

Nutrition

  • Olives are an excellent source of iron and a good source of copper.
    • Iron supports growth and development, immune function, wound healing, reproduction, and energy production.
    • Copper assists with bone formation, energy production, iron metabolism, and nervous system function.
  • Use caution if you are on a low sodium diet. Olives are high in sodium due to the processing method.

  • Prepare olives as directed per recipe.
