Cold-pressed oil is also called natural untreated oil, primarily because during its preparation, the temperature does not exceed 40°C. That allows the oil to preserve all its vitamins (A, A1, B6, C, D in E) and minerals (magnesium, phosphorous, calcium, iron, manganese, selenium and zinc). Oil is easily digestible — in fact even calming — without irritating the stomach lining or causing acid indigestion, therefore it is especially recommended for those with stomach disorders. Cold-pressed oil lowers the level of the lipoprotein cholesterol. It is rich in vitamin E, which is essential for the normal functioning of the nervous system and also has an influence on fertility and the renewal of red blood cells.
