Olive Oil vs Vegetable Oil: Which is Healthier?

Updated: Aug 15, 2023


Plant oils are a staple in most pantries, used for cooking, sautéing, frying, and drizzling, as well as for preventing foods from sticking together. Olive oil and vegetable oils are two of the most popular plant-based oils used worldwide, each boasting unique characteristics. In this article, we will delve into the health aspects of both oils to determine which one is better for you.


To determine the healthiest option, it's crucial to explore the main differences between olive oil and vegetable oil. Olive oil, derived from pressed olives, is commonly used as a salad dressing, for sautéing, and as a bread dip. Its nutritional profile reveals a rich source of Vitamins K and E, especially in extra virgin varieties, and it is abundant in antioxidants, which possess anti-inflammatory properties. Olive oil is minimally processed, with extra virgin olive oil being the least processed, having a smoke point of 390°F.

On the other hand, vegetable oils are a blend of fats from multiple plant sources, including sunflower, corn, canola, soy, and safflower. Primarily used for baking and frying, their nutritional composition varies depending on the blend and typically retains fewer nutrients after processing. Vegetable oils are low in antioxidants and often undergo extensive processing. Their smoke point is around 400°F.

Processing and Flavor:

The processing of plant oils plays a vital role in both their flavor and nutritional composition. Olive oil is obtained solely from pressed olives, making extra virgin olive oil the least processed version. Conversely, vegetable oil requires blending oils from different sources, necessitating further processing to remove impurities and create a neutral flavor.


The degree of processing significantly affects the nutritional composition of oils. Olive oil contains higher amounts of heart-healthy monounsaturated fats such as oleic acid, linoleic acid, and palmitic acid. In contrast, vegetable oil predominantly contains omega-6 polyunsaturated fats. Monounsaturated fats offer anti-inflammatory benefits, while excessive consumption of omega-6 polyunsaturated fats may harm heart health.

Moreover, the refining process of vegetable oil leads to the destruction of micronutrients, antioxidants, and beneficial plant compounds like tocopherols, phytosterols, polyphenols, and coenzyme Q10. In contrast, extra virgin olive oil, being the least processed type, retains antioxidants and anti-inflammatory compounds like tocopherols, carotenoids, and polyphenols.

Similarities between Olive Oil and Vegetable Oil:

Both olive oil and vegetable oil blends have similar smoke points of around 400°F. Some types of olive oil, like pomace oil, can be highly processed and lack essential nutrients and flavor. To ensure you choose a flavor-packed oil with retained nutrients, look for labels indicating "virgin" or "extra virgin."

Which Oil is Healthier?

When it comes to health considerations, extra virgin olive oil emerges as the winner. Being among the least processed cooking oils, it retains a wealth of antioxidants, vitamins, and minerals. Extensive research has shown that the antioxidant and polyphenolic compounds in olive oil offer significant heart health benefits. In contrast, vegetable oil, with its extensive processing and minimal beneficial nutrients, may only provide empty calories.
