No, rapeseed oil is not dangerous to your health when used properly. We are Elijah and Leo, and we wanted to unravel the true of the false on this oil that makes so much talk. Because yes, between rumors about erucic acid and questions about cooking, many of you are questioning us. Here's what to remember:
- Modern varieties contain less than 2% erucic acid (compared to 50% previously)
- Its omega-6/omega-3 ratio is excellent for cardiovascular health
- Risks exist only in case of misuse or storage
- It is not recommended for high temperature frying
Let's decorate each aspect of this oil together to allow you to make informed choices.
Rape oil: why is it controversial?
The rapeseed oil has had a sulphurous reputation since the 1970s. At that time, cultivated varieties contained up to 50% erucic acid, a compound suspected of causing heart damage in animals. This story has marked the minds. Today, the new varieties (called "canola" in North America) have been developed to drastically reduce this compound. Despite this, concerns persist on the Internet, often fuelled by outdated information.
What are the potential dangers of rapeseed oil?
The real risks are limited but deserve your attention:
- Rapid oxidation omega-3s are fragile and quickly resent heat and light
- Excessive heating : virgin oil has a low smoke point (107°C)
- Calorie intake : 900 kcal per 100 g, like all oils
- Cross Allergies possible in people allergic to mustard
Erucic acid: a real risk today?
Rest assured: this risk belongs to the past. European regulations impose a rate of less than 2 % erucic acid in food oils. Current varieties largely meet this standard. Studies that showed adverse effects involved doses well above what we consume. Because of one tablespoon per meal, you have no reason to worry.
Can we heat rapeseed oil safely?
Depends on the type of oil you use. Here is a summary table:
| Type of oil | Smoke point | Recommended use |
| Virgin rape | 107°C | Cold seasoning only |
| Refined colza | 200-230°C | Sweet cooking, pastry |
| Olive | 210°C | Medium cooking |
| Sunflower | 230°C | Cooking and light frying |
Refined rapeseed oil supports smooth cooking without problems. On the other hand, virgin oil should never be heated under pain of producing harmful compounds.
Should we avoid fried rapeseed oil?
We advise against it. Even refined, rapeseed oil is quickly oxidized at high temperature. For frying, prefer oleic sunflower oil or peanut oil, more stable. If you occasionally use refined rapeseed oil for cooking in the oven or pan over medium heat, this remains acceptable.
Rape oil and allergies: should we worry?
Allergies to rapeseed oil are rare. They mainly concern people who are allergic to Brassicaceae (mustard, cabbage, broccoli). Refined oil presents a near-zero risk as refining eliminates allergenic proteins. If you are in doubt, consult your allergenologist before adding this oil to your diet.
How to keep rapeseed oil well to avoid risks?
Conservation is the key to preserving the benefits of this oil:
- Store it in the refrigerator, especially if it is virgin
- Keep it safe from light in its original packaging
- Eat virgin oil within 6 months after opening
- Refined oil can be preserved for up to 12 months
- Dispose of any oil with a rancid smell or a bitter taste
How much is safe to consume?
The recommended dose is one tablespoon per meal per person, about 10 to 20 g per day. This amount brings you 50% of your vitamin E needs and 20% of your vitamin K1 needs. It also covers much of your essential omega-3 intakes. Variate with other oils (olive, nuts, flax) to enjoy a complete nutritional spectrum.
Virgin rapeseed oil vs refined: what impact on health?
The virgin oil, extracted cold without chemical treatment, retains more nutrients and antioxidants. Its more pronounced flavour (chou or hay notes) may surprise. The refined oil loses part of its omega-3 during the heating process but offers better stability and a neutral taste. Our advice: Keep both in your kitchen and use each one according to your needs.
Do the benefits of rapeseed oil offset its risks?
Absolutely. This oil has a remarkable nutritional profile: 60 % of diomega-9, 20 % of diomega-6 and 10 % of diomega-3. This ratio promotes cardiovascular health by reducing bad cholesterol (LDL) and increasing good cholesterol (HDL). Studies show a decrease in the risk of infarction and stroke. Omega-3 also supports brain function and helps prevent age-related cognitive disorders.
Is rapeseed oil dangerous for children or pregnant women?
No, she's even recommended! Omega-3s are essential to the development of the brain and nervous system of the foetus and young child. In addition, the pregnant women are advised to vary their intakes of vegetable oils, including rapeseed. Simply respect age-appropriate amounts and focus on seasoning virgin oil to maximize nutritional intakes.
What do the scientific studies say about the toxicity of rapeseed oil?
Recent research is reassuring. A meta-analysis published in British Journal of Nutrition confirms the beneficial effects of rapeseed oil on cardiovascular markers. Clinical studies also show an improvement in insulin sensitivity in people with diabetes. The old fears of erucic acid are no longer relevant to modern varieties.
What alternatives to rapeseed oil if you have a doubt?
If you prefer to avoid rapeseed oil, here are our suggestions:
- Olive oil : excellent for cooking, rich in omega-9
- Flax oil : champion of omega-3 (to consume raw)
- Nut oil : tasty seasoning
- Camelin oil : local alternative rich in omega-3
