How many olives do I need to eat to equal 1 tablespoon of oil?
It depends on how big the olives are and what their oil content is. The large black canned olives are actually quite low in oil - sometimes only 7%, which is why they are table olives and are not used generally to make oil. Some smaller olives used primarily for oil making can have up to 35% oil content. Olives can range from 1 to 14 grams in weight. There is about 1 tablespoon of olive oil in:
20 medium Mission olives that had an oil content of 20%
40 small ripe black olives
20 jumbo ripe black olives
7 super colossal ripe black olives
There are fewer calories in a tablespoon of oil than any of the above scenarios because olives also have carbohydrates which add calories.
