What are the differences between green olives, black olives and stuffed olives?
Stuffed olives, naturally, include some other food inside, for example an anchovy. Black olives generally have fewer calories, some varieties containing only 79 kcal per hundred grams, equivalent to around 25 calories per portion, as opposed to green olives, which on average contain 150-177 (around 40 kcal per portion). Black olives also contain less salt and more iron.
