Olive oil is more than just a flavorful addition to meals – it’s a nutrient-dense superfood with powerful health benefits. Rich in heart-healthy monounsaturated fats and antioxidants, it has been linked to reduced inflammation, improved cholesterol levels, better blood sugar control, and even long-term protection against chronic diseases like heart disease, type 2 diabetes, and cancer.
Beyond its own benefits, olive oil also has the unique ability to enhance the value of other foods by helping your body absorb fat-soluble vitamins (A, D, E, K) and protective plant compounds more effectively. How you use olive oil in your everyday eating can make a difference when it comes to both flavor and function.
Why Olive Oil Matters for Nutrient Absorption
Aside from the robust flavor that olive oil adds to any of your favorite foods, there can also be legitimate health reasons to combine them – one being to increase vitamin absorption.
Vitamins come in two categories: water-soluble and fat-soluble. Fat-soluble vitamins (A, D, E, K) actually need fat to be absorbed, which means pairing foods rich in these nutrients with olive oil enhances their bioavailability.
Similarly, plant compounds like lycopene (tomatoes), lutein (greens), and beta-carotene (carrots) are “unlocked” by healthy fats. These compounds have antioxidant properties that have been associated with benefits such as improved heart health, reduced inflammation, and protection against stress-induced cell damage.
Extra virgin olive oil (EVOO) is ideal because it is richest in antioxidants when compared to more refined versions of olive oil.
You might be wondering about the value of some specific olive oil combinations that don’t necessarily include fat-soluble fats, such as olive oil with lemon, aloe vera, or chia seeds, so we’ll explore these in more detail.
What Makes Olive Oil So Healthy?
Before exploring pairings, it’s important to understand what olive oil brings to the table:
Omega-9 Oleic Acid
-
Olive oil is nearly 100% fat, with most of that being heart-healthy monounsaturated fatty acids – primarily omega-9 oleic acid.
-
These fatty acids have been linked to a range of beneficial effects on health, including improved cholesterol profiles by lowering LDL (“bad”) cholesterol and increasing HDL (“good”) cholesterol, reducing inflammation, and promoting better insulin sensitivity.
-
Diets rich in oleic acid also appear to influence fat metabolism and body composition by promoting weight regulation and reducing abdominal fat through mechanisms such as AMPK signaling and inflammation control.
- High intake of oleic acid has also been linked to improved vascular and metabolic health.
Olive Oil Polyphenols
- The polyphenols in extra-virgin olive oil have unique antioxidant and anti-inflammatory properties that may further protect against obesity and cardiovascular disease.
- These polyphenols – especially oleocanthal and oleacein – have been associated with benefits such as anti-cancer effects, brain health benefits, and reduced inflammation.
Vitamins in Olive Oil
- Olive oil also contains fat-soluble vitamins E and K, which have been associated with antioxidant benefits, blood clotting, heart health, and bone health.
- While olive oil does not contain vitamin D and vitamin A, its fat content does help boost the absorption of these vitamins.
The Best Olive Oil Food Pairings for Nutrient Absorption
Olive Oil and Tomatoes or Tomato Sauce
Combining tomato with olive oil maximizes the uptake of lycopene, which has been shown to have cardiometabolic effects. Because cooked tomatoes have more potent levels of lycopene, you’ll get even more benefit from adding olive oil to a tomato sauce or other cooked tomato dish.
Olive Oil and Dark Leafy Greens
This combination enhances the bioavailability of lutein and zeaxanthin bioaccessibility – which have been associated with eye health, brain health and antioxidant benefits. The fat in the olive oil also helps boost absorption of the vitamin K in the greens, a vital nutrient for bone health, blood clotting and heart health. Try spinach, kale, arugula, or chard. You’ll get similar benefits with other green produce like broccoli and zucchini.
Olive Oil and Roasted Carrots
Olive oil, like other fats, helps increase the absorption of the beta-carotene in the carrots when compared to a low-fat preparation. The vitamin A in carrots has also been associated with eye health and protection against macular degeneration. Consuming vitamin A in food form rather than taking a high-dose supplement is generally recommended to protect against adverse health effects of mega-dosing vitamin A, so pairing a vitamin A-rich food like carrots with olive oil is a great move for making the most of what you’re eating.
Olive Oil and Fatty Fish
Olive oil and fish are a Mediterranean staple that work in perfect harmony. The healthy fats and polyphenols in olive oil complement the omega-3s in fish, supporting heart, brain, and metabolic health. Olive oil also supports absorption of fat-soluble nutrients like vitamins D and E found in fish while protecting delicate omega-3s from oxidation.
In salmon and other pink fish, it can even enhance absorption of astaxanthin, a powerful antioxidant linked to skin and eye health. A drizzle of high-phenolic olive oil over cooked fish brings together freshness, flavor, and lasting nourishment.
Olive Oil and Avocado
Both olive oil and avocado are packed with heart-healthy monounsaturated fats, and when enjoyed together, help the body better absorb fat-soluble vitamins and antioxidants – like vitamin E and carotenoids – found in avocados.
Olive Oil and Eggs
Combining eggs with olive oil is a simple way to get more from both foods. The healthy fats in extra virgin olive oil help your body absorb the fat-soluble nutrients naturally present in eggs – like vitamins D and E – while also supporting the uptake of antioxidants from any vegetables or greens on the plate. Drizzling olive oil over poached or fried eggs not only adds rich, peppery flavor but also helps your body make the most of every nutrient.
Olive Oil and Lemon
This is a classic duo – olive oil boosts absorption of whatever fat-soluble nutrients you may be enjoying it with, while lemon adds antioxidant vitamin C and a burst of complementary flavor. Additionally, lemon (like other citrus), has been associated in studies with reduced blood pressure, kidney stone prevention, and anti-inflammatory benefits. Vitamin C also helps enhance iron absorption.
Olive Oil and Vinegar
The acetic acid in vinegar further enhances the absorption of fat soluble nutrients that already get a boost from olive oil and adds a refreshing flavor. Apple cider vinegar may be a great option for those also looking to support healthy blood sugar levels. Because both olive oil and vinegar have been shown independently and together to help improve glycemic response, they’re the perfect combination to include in a carbohydrate-containing meal.
Olive Oil and Bread or Grains
This combination enhances satisfaction, flavor, and absorption. The fat in the olive oil also helps buffer the breakdown of the starch in the bread or grains, supporting more stable blood sugar.
Olive oil with Aloe Vera
While there is not much scientific backing for this combination, a less common pairing, olive oil and aloe vera may complement each other well in digestive contexts. However, more research is needed in this area.
Olive Oil with Chia Seeds
While research doesn’t show anything magical about pairing chia seeds with extra virgin olive oil, because they both have notable heart-healthy aspects, they can complement one another quite well. Chia seeds are a good source of fiber and plant-based omega-3 fatty alpha-linolenic acid (ALA). Additionally, both olive oil and chia seeds contain antioxidants that help reduce disease risk.
Everyday Mediterranean-Style Eating with Olive Oil Pairings
Olive oil is a key component of the Mediterranean diet, a style of eating that has been consistently linked in research to lower risk of heart disease, type 2 diabetes, certain cancers, and cognitive decline. It emphasizes vegetables, fruits, whole grains, legumes, fish, nuts, olive oil, and herbs and spices, with minimal processed foods ,red meat, or added sugar. Olive oil is the primary fat.
When paired with nutrient-rich foods like leafy greens, tomatoes, and carrots, olive oil enhances the absorption of fat-soluble vitamins and antioxidants, helping the body unlock their full health benefits. Here’s a sample one-day menu to use for inspiration that showcases some delicious olive oil pairings and also includes plenty of protein and fiber to keep you full.
