According to a study carried out by the Faculty of Experimental and Technical Sciences at San Pablo-CEU University, Extra Virgin Olive Oil is the best essential fatty acids supplement during pregnancy. This fatty acid, which is formed from the linoleic acid present in virgin olive oil, is also vital for the development of the brain of the foetus and its deficiency can delay it. We can conclude that Extra Virgin Olive Oil is a balanced source of essential fatty acids due to its content of linoleic and linolenic acids, the precursors of arachidonic, DHA and EPA acids, and its proportion of vitamin E compensates for oxidative processes associated with the consumption of polyunsaturated fats.
