Comparisons
Avocado vs Olive Oil
Avocado is a whole-food fat with fiber and water; olive oil is concentrated liquid fat. The better choice depends on calories, texture, cooking, and serving size.
Short answer
Avocado and olive oil are both useful unsaturated-fat foods, but they are not interchangeable. Per 100g, olive oil has about 884 calories and 100g fat; avocado has about 160 calories, 14.7g fat, and 6.7g fiber. Use avocado when you want body, texture, fiber, and fullness; use olive oil when you need a liquid fat for dressing, cooking, roasting, or finishing.
What readers should remember
- Olive oil is much denser by weight because it is pure fat.
- Avocado adds fiber, water, potassium, and creamy texture.
- The fairest comparison is by realistic serving, not only by 100g.

Realistic serving comparison
Most people do not eat 100g of olive oil. A serving comparison is more useful for real meals.
| Serving | Calories | Fat | Fiber | Best use |
|---|---|---|---|---|
| Half medium avocado, ~100g | ~160 | ~14.7g | ~6.7g | Toast, bowls, salads, dips, spreads |
| 1 tbsp olive oil, ~13.5g | ~120 | ~13.5g | 0g | Dressings, sauteing, roasting, finishing |
| 2 tbsp mashed avocado, ~30g | ~48 | ~4.4g | ~2g | Small spread or sauce base |
| 2 tsp olive oil, ~9g | ~80 | ~9g | 0g | Light drizzle or dressing base |
Which should you use?
| If your goal is... | Better fit | Why |
|---|---|---|
| Creaminess with fiber | Avocado | It adds body, water, and fiber, so it works as a spread or dip. |
| Cooking or roasting | Olive oil | It is liquid and coats pans, vegetables, and proteins evenly. |
| A pourable dressing | Olive oil | It emulsifies with vinegar, lemon, mustard, herbs, and salt. |
| A whole-food swap for mayo or butter | Avocado | It gives creamy texture with less concentrated fat by volume. |
| Maximum vitamin E per gram | Olive oil | Olive oil is much more concentrated in vitamin E by weight. |
| A balanced plate | Either, or both | Use avocado for structure and a small amount of olive oil for aroma and finish. |
Whole food vs concentrated oil
The core difference is the format. Avocado carries fat inside a whole fruit with fiber, water, potassium, and a little protein. Olive oil is pressed oil: no fiber, no water, and almost entirely fat. That makes olive oil calorie-dense, but also useful in small amounts because it is easy to drizzle, cook with, and blend into dressings.
The calorie comparison people get wrong
Per 100g, olive oil has about 5.5 times the calories of avocado. But 100g of oil is about 7 tablespoons, which is far more than a normal serving. For a real plate, compare half an avocado with 1 tablespoon of olive oil. They are much closer in calories, while doing different jobs in the meal.
How to use them together
Avocado and olive oil often work best as a pair. Mash avocado with lemon, herbs, and flaky salt, then finish with a small drizzle of olive oil. The avocado gives body and freshness; the olive oil adds aroma and a smoother finish.
Responsible nutrition framing
This guide compares foods, not medical outcomes. If you are managing cholesterol, diabetes, kidney disease, pregnancy nutrition, or a medically prescribed diet, use personal guidance from a qualified clinician. For everyday cooking, the practical takeaway is simple: avocado and olive oil can both be useful, especially when they replace heavier saturated-fat toppings rather than being added without portion awareness.

Common questions
Frequently asked questions
Is avocado healthier than olive oil?
Neither is automatically healthier. Avocado is a whole food with fiber, water, potassium, and fewer calories per 100g, while olive oil is a concentrated oil with more vitamin E per gram and easier use in cooking. The better choice depends on the meal and portion.
Which has more calories, avocado or olive oil?
Per 100g, olive oil has about 884 calories and avocado has about 160 calories. A realistic serving is closer: 1 tablespoon of olive oil is about 120 calories, while half a medium avocado is about 160 calories.
Can avocado replace olive oil in recipes?
Sometimes. Mashed or blended avocado can replace oil in spreads, dips, creamy sauces, and some dressings because it adds body and fiber. Olive oil is better when a recipe needs liquid fat, sauteing, roasting, or a pourable finish.
Which has more monounsaturated fat?
Olive oil has more monounsaturated fat by weight because it is pure fat: about 73g per 100g versus about 9.8g per 100g for avocado. Avocado provides its fat inside a whole fruit with fiber and water.
Can you eat avocado and olive oil together?
Yes. Avocado and olive oil work well together on toast, salads, bowls, dips, and Mediterranean-style plates. Use avocado for creaminess and texture, then add a small drizzle of olive oil for aroma and finish.
