Rapeseed oil is made from the seeds of rapeseed, which grows well in all climatic conditions. The oil has a waste-free production: cake is used in the preparation of animal feed.
There are two types of rapeseed oil – industrial and culinary. Industrial is used in the production of lubricants for engines, and culinary is added to the composition of products or eaten in its pure form.
Industrial oil should not be eaten. It is 60% erucic acid, which is toxic and carcinogenic to humans.
The situation with rapeseed oil is the same as with palm oil. Unscrupulous food manufacturers often replace edible oil with technical oil, resulting in people buying a very harmful product.
Composition of rapeseed oil
Rapeseed oil is a healthy source of omega-3, 6 and 9 fatty acids. It is important that the oil contains them in the correct proportion and is easily absorbed by the body.
1 tablespoon of rapeseed oil contains:
- vitamin E-12%;
- vitamin K-12%;
- calories – 124.
What fatty acids does rapeseed oil consist of:
- monounsaturated – 64%;
- polyunsaturated – 28%;
- saturated – 7%.
The product does not contain a single gram of TRANS fats and preservatives that are harmful to the body.
The maximum heating temperature of rapeseed oil is 230 C. At this temperature, it does not emit carcinogens and does not become dangerous to health. In rapeseed oil, this figure is higher than that of olive oil, which can not be fried and baked food.
The caloric content of rapeseed oil is 900 kcal.
Use of rapeseed oil
The product is rich in monounsaturated fatty acids, which should be present in our diet every day. Their use reduces cholesterol and protects against stroke. In rapeseed oil, the amount of these fats is comparable to the composition of oily fish.
Omega-3s penetrate brain cells when consumed and protect against dementia and Alzheimer’s disease. In addition, it is a strong antioxidant! Every day, eating a spoonful of rapeseed oil with vegetables or cereals, you get half of the daily allowance from the omega-3.
Omega-6 fats are useful for the bronchi and circulatory system. However, their excess provokes the development of inflammation. Nutritionists recommend using omega-6 and omega-3 in a 2:1 ratio to get all the benefits and avoid harm. Rapeseed oil boasts exactly this proportion in the composition.
If you want to keep your skin young, add rapeseed oil to your diet. Useful fats and vitamin E in its composition are involved in cell renewal and slow down the appearance of wrinkles.
Use the oil as a salad dressing – it improves the health of the eyes and joints. These properties are especially important for the elderly.
The harm of rapeseed oil
Compared to coconut and olive oil, rapeseed oil contains less saturated fat. Therefore, it is more useful for those who want to lose weight.
Rapeseed oil contains many phytosterols that strengthen the immune system and help fight viruses. Add it to your daily autumn diet and strengthen your immune system without medication.
The use of rapeseed oil is especially useful for vegetarian diets.
These useful properties apply only to unrefined cold-pressed rapeseed oil. Avoid using refined foods – they contain very few useful substances.
Harm and contraindications of rapeseed oil
The harm is manifested by excessive use. Since this is a high-fat product, you should not get too carried away with it – it can cause obesity and increased work of the gastrointestinal tract.
Be sure to follow the daily intake of omega-6. Their excess can cause inflammation in the body.
Oil is forbidden to use when:
- exacerbation of gallstone disease;
- individual intolerance.
If you use technical rapeseed oil (if an unscrupulous manufacturer has replaced it with food), you may see:
- disorders in bone development;
- failures in the hormonal background;
- the appearance of visceral fat;
- chronic kidney and liver diseases.
Baby food and rapeseed oil
Until now, scientists are hotly debating whether rapeseed oil is useful for children. Often it is added to the diet of infants (not in its pure form, but as part of mixtures), so that the child receives useful fatty acids that are not produced in the body. However, due to the possible substitution of edible oil for technical oil, the child may get more harm than good.
If you are sure that rapeseed oil is edible, you can not worry about the health of your child. The fat content of this oil is identical to the fat content of breast milk.
Analogs of rapeseed oil
For a change, you need to enrich your diet with other useful oils:
- Olive oil. The most affordable oil. It is rich in antioxidants and improves brain function;
- Linseed oil. Reduces blood pressure and strengthens the heart;
- Coconut oil. Useful oil for those who are active in sports;
- Avocado oil. Improves heart function and contains a lot of actioxidants.
