Olives are a Mediterranean fruit often enjoyed as a salty snack and are a source of healthy unsaturated fats. People have enjoyed them since at least 410 B.C., and they continue to be popular today. While olives do have some excellent nutritional qualities and can certainly be part of a healthy diet, a balanced diet that includes a variety of foods is key.
Olives, also known as Olea europaea, are subtropical fruits originating in the Mediterranean. They grow on olive trees, which are only ten meters tall. It takes three to four years for the trees to start bearing olives, but they won’t be in full production until 12 to 20 years of growth.
Olives can be eaten on their own as whole fruits. However, they are required to undergo processing to be edible. Common processing methods are alkaline hydrolysis or slow acid and enzymatic hydrolysis. This is because fresh, raw olives are extremely bitter, and they cannot be eaten raw and unprocessed.
Nutritional Value of Olives
Processed olives can be eaten when they are green or black. Green olives are unripe, and black olives are ripe. The nutrition facts for both varieties are listed below. For 50 grams of black olives, approximately ten olives, the energy content is 58 kilocalories, with 3.83 grams of monounsaturated fats and 0.31 grams of polyunsaturated fats.
For 50 grams of green olives, approximately 12 olives, the energy content is 72.5 kilocalories, with 5.65 grams of monounsaturated fats and 0.66 grams of polyunsaturated fats. Black olive nutrition and green olive nutrition do vary slightly. The main differences are that green olives are higher in fat, including healthy monounsaturated fats, sodium, dietary fiber, and calories.
Health Benefits of Olives
Olives contain healthy fats, but it is essential to be mindful of the sodium content. The Dietary Guidelines for Americans recommend that individuals limit sodium intake to 2300 mg per day, which is equivalent to one teaspoon of salt. One portion of black olives provides 16 percent of the daily value of sodium. One portion of green olives provides 34 percent of the daily value of sodium.
A 2020 study found that consuming ½ tablespoon of olive oil per day resulted in a 14 percent lower risk of cardiovascular disease and an 18 percent lower risk of coronary heart disease. The study also found a decreased risk of heart disease when individuals replaced 5 grams of butter, margarine, mayonnaise, or dairy fat with olive oil.

A 2018 review article reported that extra virgin olive oil may lessen chronic inflammation due to its polyphenol content, which are beneficial plant chemicals found in olive oil. This potential benefit was seen in both animal and human studies.
Impact on Weight and Overall Health
High consumption of olive oil is one of the main components of the Mediterranean diet. The other main components of the Mediterranean diet include a high consumption of vegetables, fruits, nuts, cereals, and whole grains, a moderate consumption of poultry and fish, and a low consumption of sweets, red meat, and dairy products.
Recent findings from a 2022 review study reported that weight loss could be achieved through the Mediterranean diet, which in turn can reverse the negative health effects caused by obesity. This indicates that olive oil could be a dietary staple in a healthy diet that contributes to weight loss and health benefits in general.
In practice, for individuals looking to incorporate olives into their diet, it’s essential to consider the overall dietary pattern. Olives can be a healthy addition to a balanced diet, but it’s essential to be mindful of portion sizes and sodium content. By pairing olives with other whole foods and being aware of daily sodium intake, individuals can enjoy the health benefits of olives while minimizing potential drawbacks.
Eating Olives in Moderation
Olives should be consumed in moderation and alongside other healthy whole foods. If you have concerns or questions about how to manage your sodium intake, contact a Registered Dietitian.
Olives can be added to many meals or even just eaten as part of a healthy snack. Some examples include making homemade whole wheat crust pizza and using sliced olives as a topping, making a Greek salad with olives, or adding olives to a pasta dish. By incorporating olives into your diet in a balanced and mindful way, you can enjoy their nutritional benefits while maintaining a healthy lifestyle.
They can be a tasty and healthy addition to various meals.
