Olives, Olive Oil and Keto: Things to Know

The ketogenic diet recommends keeping fruit intake to a minimum.

Most fruits are not allowed for consumption because they're high in carbohydrates which goes against the dietary standards of keto. But, there are a select few fruits that are keto-approved, contain plenty of micronutrients, and can be consumed plentifully.

One of these fruits is olives.

In this article, you'll learn exactly why olives are so good for you and how you can incorporate them into your keto lifestyle.

What are Olives?

Olives are a small fruit that grows on olive trees.

They're from a group of fruit called drupes and are related to cherries, mangos, pistachios, almonds, and peaches. Olives have been cultivated by humans for 1000s of years and can be cured in different solutions to give them different tastes.

But not all olives have the same nutrient value!

Many olives are soaked in a solution that contains lye and water to soften them. While this is a relatively fast process, it usually removes most of the nutrients in the fruit. Conversely, other olives are cured in brine water which takes a longer period of time but maintains a strong nutrient profile and a richer flavor.

The most nutrient-dense olives we recommend are from organic brands as they’re most likely treated with a brine solution instead of lye.


What is Extra Virgin Olive Oil?

Extra virgin olive oil (EVOO) is a great addition to any ketogenic diet.

The "extra virgin" label refers to the amount of acidity of the oil and the extent of how much processing is used to extract it.

EVOO is 100% not chemically processed or heated. It's extracted directly from the olives by pressing or spinning them once they're mashed into a paste. The highest quality extra virgin olive oils are the most nutrient dense, lower in acidity and rancidity, and also has the strongest flavor.

Note: Extra virgin olive oil has a low smoke point and will break down when it's heated too high, breaking down nutrients and causing a strange flavor. If you're cooking with high heats, consider using an oil with a higher smoking point such as avocado oil.


Excellent Source of Vitamins and Essential Minerals

Olives are extremely high in vitamin E and antioxidants.

Research shows that they are great for heart health and may help protect against some cancers as well as osteoporosis[*]. The healthy fats in olives are commonly extracted to produce extra virgin olive oil, which is considered a staple in the ketogenic diet.
