If the olive oil of the first pressing, it contains many useful chemicals phytochemicals that can adversely affect the cancer cells and are capable of causing their death. The studies were conducted by doctors from the Catalan Oncology Institute and the University of Granada, who tried to find out the varieties of olive oil, the most effective in treating cancer.

Studies have shown that the main complex phenols, which are contained in high-quality olive oil, have an acidity of less than 0. 8%, can dramatically suppress the high activity of the gene for HER2 cancer, present in the development of breast cancer.

The first pressing of olive oil means when the olives are squeezed, without using heat or chemical treatment. Only such an oil contains many useful ingredients lost by another way of cooking.

Biologists tested the properties of natural oil in the fight against breast cancer cells.

Conclusions showed that polyphenols lignin and secoridoids particularly interfered with the work of HER2. In addition, the researchers say that it is very difficult to extract absolutely identical concentrations of active phytochemicals under normal conditions and without using laboratory experiments, that is, blindly consume high-quality olive oil. Oncologists of Spain argue that the polyphenols contained in the oil can be used in the development of new drugs, against cancer.
