Which fat is the healthiest for humans?
For decades, fat was considered the number one enemy of health. However, today the scientific evidence is clear: not all fats are the same. In fact, some are essential for the proper functioning of the body.
But then the key question arises:
Which fat is truly the healthiest for humans?
In this article we analyze the current scientific evidence, debunk myths and explain why organic extra virgin olive oil is positioned as the benchmark within high-quality healthy and gourmet food.
Types of fat: understanding the difference is key
To answer correctly we must differentiate between the main types of fat present in the diet.
1 Saturated fats
Found in butter, processed meats, and some dairy products.
High consumption is associated with a higher cardiovascular risk according to the World Health Organization (WHO) .

2 Trans fats
Industrial fats present in ultra-processed products.
They are considered the most harmful to cardiovascular health and the WHO recommends reducing them to practically zero in the diet.
3 Unsaturated fats
Herein lies the real difference:
- Monounsaturated
- Polyunsaturated
These are the fats associated with better metabolic and cardiovascular health within balanced dietary patterns.
So… which is the healthiest fat?
Scientific evidence indicates that monounsaturated fats , especially those present in extra virgin olive oil (EVOO) , are the most beneficial for the body.
Because?
Because:
- They improve the lipid profile (increase HDL and help maintain healthy LDL levels)
- They contribute to inflammatory balance
- They contain natural antioxidants (polyphenols)
- They are associated with a lower cardiovascular risk within the Mediterranean diet
According to the Harvard TH Chan School of Public Health , olive oil is the main source of healthy fat in the Mediterranean diet, a dietary pattern linked to greater longevity.
What makes organic extra virgin olive oil so special?
Not all olive oil is the same.
Differences between refined and extra virgin olive oil
Extra virgin olive oil:
- It is obtained solely through mechanical processes
- It does not undergo chemical processes
- Preserves natural polyphenols and antioxidants
- It maintains its sensory profile intact
In contrast, refined oils lose a large part of their bioactive compounds during the industrial process.
The added value of organic EVOO
When it's also eco-friendly:
- It is grown without synthetic pesticides
- Respect the natural balance of the soil
- It reinforces a coherent and sustainable food model

What does science say about olive oil and health?
One of the most relevant studies is the PREDIMED trial, published in the New England Journal of Medicine , which showed that a Mediterranean diet supplemented with extra virgin olive oil significantly reduces cardiovascular risk.

Furthermore, the polyphenols in EVOO have been recognized by the European Food Safety Authority (EFSA) for their contribution to the protection of blood lipids against oxidative damage when consumed in adequate amounts within the usual diet.

Is olive oil the best fat for cooking?
Yes, and this point raises many questions.
Thanks to its oxidative stability and high antioxidant content, extra virgin olive oil:
-
It withstands normal cooking temperatures well.
-
It is more stable than many refined vegetable oils
-
It maintains its nutritional profile within moderate domestic use
Therefore, it is suitable both raw and for moderate cooking.
How to consume EVOO to best benefit from its properties
Extra virgin olive oil has been part of the Mediterranean diet for centuries. Modern science supports its regular consumption as part of a balanced diet.
Studies place the usual intake at around 20 to 50 ml per day , which is approximately equivalent to:
- 2–4 tablespoons spread throughout the day
- 2–4 teaspoons added to different meals
- or a small "shot" glass (30–40 ml) within the usual eating pattern
The determining factor is not the exact moment, but the consistency and quality of the oil.
In its raw state: preserving its natural wealth
When consumed raw —on bread, salads, vegetables, legumes or as a finishing touch to a dish— EVOO retains its phenolic and antioxidant profile better.
In the morning: integrate the habit
In many Mediterranean regions, it's common to start the day with olive oil at breakfast, for example on toast with fresh tomato. This practice makes it easy to incorporate quality monounsaturated fats into a balanced diet.
Extra virgin olive oil with lemon: a natural combination
The mixture of extra virgin olive oil with lemon juice is part of the Mediterranean culinary tradition.
From a nutritional point of view:
- EVOO provides monounsaturated fats and phenolic compounds.
- Lemon provides vitamin C and antioxidant flavonoids.
Both can be integrated into a balanced and natural diet.

In moderate cooking
Thanks to its composition rich in oleic acid and natural antioxidants, extra virgin olive oil has good stability for regular domestic use, and can be used both raw and in moderate cooking.
Ultimately, the benefits of extra virgin olive oil don't depend on a single action, but rather on its consistent integration into your daily diet. Quality, balance, and regularity are key.

Conclusion: The healthiest fat combines science and nature
Current scientific evidence is clear:
Monounsaturated fats , especially those in extra virgin olive oil, are the healthiest option within a balanced diet.
And when that oil is:
- Extra Virgin
- Ecological
- Handcrafted
- Rich in polyphenols
We're not just talking about health, but about gastronomic excellence.
Because choosing the right fat is not just a nutritional issue.
It is a statement of criteria, culture and respect for what we consume.
