Cold pressed oil – what is it characterized by?




We have been hearing for a long time that cold-pressed oils should be an essential part of our diet. Why is this method considered the healthiest, why do we need omega-3 and omega-6 fatty acids and how to choose the best oils?

 

Cold pressed oil - how is it made?

Cold pressing is the oldest method of obtaining beneficial vegetable oils. The preparation of such an oil requires several steps. First, select the highest-quality seeds, and then, using a special hydraulic or auger press, press out of them what is best for your health. It is extremely important during the entire process to keep the temperature of the raw materials below 40 degrees, and then cool the oil to about 10 degrees so that it stays fresh for longer and does not lose the most important nutrients. After that, the oils should be stored in dark bottles - this also affects the preservation of nutritional value and the shelf life of the product.

When we decide to use cold-pressed oil, we should remember that it is not suitable for frying or heating. We can add it to cold snacks or salads - all cold-pressed oils retain their characteristic taste, so they can be used as an additive to enhance the taste of various (served cold!) Dishes.
Cold pressed oil and refined oil

The situation is completely different with refined oils. The process of hot pressing deprives them of their taste and smell - thanks to this neutrality, refined oils are used for frying. Unfortunately, when the seeds are subjected to the temperature of 100 degrees Celsius and then the process of refining - the result is a product devoid of the most valuable nutrients and essential acids.

The advantage of this method is the possibility of obtaining more product, the possibility of consuming it by allergy sufferers and using it for frying. According to some, such oils have a more aesthetic appearance because they are clear.

The biggest disadvantage of refining is, as we have already mentioned, depriving the product of the most valuable ingredients for health. Also, the lack of taste and smell indicates that such an oil is distant from nature - unlike its cold-pressed cousin!
What plants can cold-pressed oil be obtained from?

Cold-pressed oils are obtained from the seeds or fruits of oil plants. The most popular of them are:

Canola oil
Linseed oil
Hemp oil
Sunflower oil
Milk thistle oil
Black cumin oil
Pumpkin seed oil
Evening primrose oil

Each of them is characterized by a number of health-promoting properties, for example, linseed oil is a wealth of fiber that regulates the digestive system, and milk thistle oil contains silymarin, used in liver diseases.

What are EFA acids?

We develop the acronym EFAs as "essential unsaturated fatty acids". Another term used to describe them is "polyunsaturated fatty acids". This group includes omega-3 and omega-6 fatty acids, so often mentioned by nutritionists. They are the most important in human nutrition. Why?

As proven in studies, omega-3 and omega-6 fatty acids improve the work of the heart, regulate the proper concentration of cholesterol, regulate blood pressure, and are extremely important for proper vision and support the nervous system.

In addition, they have anti-inflammatory and anticoagulant properties, and should be used in the prevention of cancer and to improve the immune system. They work positively in the case of digestive problems, and some of them show a "beauty" effect - they soothe skin lesions and strengthen hair and nails.

The source of valuable omega-3 and omega-6 fatty acids are cold-pressed oils, as well as food products such as: fatty fish, nuts, almonds, pumpkin seeds and avocados.
