The French Paradox Explained

De franse Paradox Verklaart

The French Paradox is a seemingly contradictory observation that the French suffer relatively little from cardiovascular disease, despite having a diet relatively rich in saturated fats. This is in clear contradiction with the widely held belief that high consumption of such fats is a risk factor for cardiovascular disease.

Scientists have been trying to explain (or disprove) this paradox for a long time, but have not yet been really successful in that endeavor. 

Geographic influences on diets differ between northern and southern France.

What almost everyone forgets is that France is the only country that is located in both the Mediterranean region and Northwestern Europe. This means that people in the South of France follow (or can follow) the healthy Mediterranean diet, while in Northern France they follow a diet that is quite similar to that of the Netherlands.

Olijfolie vs Boter

Olive Oil vs. Butter.

This observation makes a lot of sense because in the south of France extra virgin olive oil is used for all sorts of applications, while in the north of France, they use butter. The same boundaries separate wine drinkers from beer drinkers.

Can we at Aljeta prove this assumption? 

The explanation.

Well, quite a bit of scientific research has now been done into the prevention of cardiovascular disease in various French cities. If you summarize these studies, a clear picture emerges[1].

It does indeed appear that the further north you go, the more people suffer from cardiovascular disease. The French Paradox is actually easy to explain: it is all about averages. On average, people in the south live healthier lives than people in the north[2].

The fact that people in the South of France are healthier is undoubtedly the result of the Mediterranean diet and, yes, drinking a glass of wine also seems to help[3].

Albania as a transition zone: Dynamics of olive oil and sunflower oil

The map above also shows that Albania is part of the transition area for olive oil and sunflower oil. In the Mediterranean coastal areas, extra virgin olive oil is of course widely used, but in the north and east of the country (‘the Albanian Alps’) the cheaper sunflower oil is often used in many dishes instead of olive oil .

The result of this is that men and women in South-West Albania have (on average) a somewhat higher life expectancy than their compatriots in North-East Albania[4].

Labor Shortage Threatens Albanian Olive Harvest and Olive Oil Production

The Albanian olive harvest is severely impacted by a labor shortage, leading to a significant decline in olive oil production and exports. In the first nine months of 2024, exports dropped by 60% compared to the same period in 2023. This not only poses challenges for the domestic market but also hinders Albania’s position as an emerging olive oil producer.
