Olive oil, often considered the liquid gold of Mediterranean cuisine, is now raising economic and health questions. In Canada, the price has risen sharply in recent years, forcing consumers to rethink how they eat it. At the same time, there are concerns about the best way to preserve it to prevent health damage.
Unprecedented price increases
In 2024, the price of olive oil jumped more than 28.3% from the previous year .This increase is the highest among all food products. Faced with this situation, some Canadians are beginning to limit their consumption of olive oil, considering it almost a rare commodity. This phenomenon has emerged against the backdrop of rising prices for many foodstuffs over the past two years.
This price hike is changing culinary habits: many now consume it sparingly, saving this pleasure for special occasions or turning to less expensive alternatives.
Preservation issues
Proper storage of olive oil is important to preserve its flavor and nutritional properties. However, as the North American Olive Oil Association explains, “there is no definitive answer to the question of how long olive oil can be stored”. Signs of expired oil include a chalky colored smell or a taste that resembles rancid nuts.
To store it properly, keep it in a cool place protected from light. It can last up to a year in such conditions. On the other hand, if it is exposed to high temperatures or too bright light, its lifespan can be reduced to only three to four months. It is also important that bottles remain tightly closed so that air does not accelerate their oxidation.
Regular consumption of spoiled olive oil can cause serious health problems. In particular, risks of cardiovascular disease and various digestive disorders such as nausea, vomiting or diarrhea have been noted. Even worse, oxidized oil can cause irreversible damage to the liver.
That’s why you really need to pay attention to signs that the oil is no longer safe to consume. “In this case, it should not be consumed under any circumstances.”
Fortunately, even olive oil that is no longer safe to eat can be used in other ways. It can be used at home to:
maintain wood,
nourish the skin,
lubricate the hinges (useful tips to avoid waste).
