Rapeseed oil composition, refining and potential health effects
What it found
Rapeseed oil contains mostly unsaturated fats along with vitamin E and plant compounds.
It may help manage cholesterol, heart disease risk and blood sugar.
What they found
Studies in people and animals
Cholesterol and heart health
The oil may help people with high cholesterol and heart disease risk. It appears able to change blood fat levels in a helpful way.
Blood sugar control
Research suggests the oil could play a role in managing diabetes. It may also help keep blood sugar levels steady.
Other findings
Nutrients in the oil
Rapeseed oil contains a large amount of unsaturated fats. It also provides vitamin E, carotenoids, phenolic compounds and phytosterols.
Cooking qualities
The oil has a high smoke point and a neutral taste. These traits make it useful for many types of food preparation.
How refining changes the oil
Refining removes phospholipids, free fatty acids and smelly compounds from crude rapeseed oil. This step improves how the oil tastes and how long it keeps.
What the authors conclude
- They support using rapeseed oil for both everyday shoppers and food manufacturers.
- They point out ways to improve the nutritional quality of the oil by adjusting how it is processed.
How it was done
The authors wanted to gather what is known about the nutrients in rapeseed oil, how it behaves during cooking, and its possible effects on health.
They gathered and summarised existing research on rapeseed oil. They looked at its nutrient makeup, how it is refined, how it performs when heated, and its links to health conditions.
What it can’t tell you
- We summarised it from the abstract only.
- This work gathers past studies rather than testing the oil directly. It cannot prove that rapeseed oil causes specific health changes on its own.
