Epidemiologic data have shown that fatty acids profile in food has a direct impact on human health (Hu et al., 1999, López-Huertas, 2009 and Solfrizzi et al., 2005). It has been generally accepted that unsaturated fats have a hypocholesterolemic effect, whilst saturated fats tend to raise total cholesterol and low-density lipoproteins (LDL) levels. The latest dietary reference intakes of fat for a healthy population are from 20% to 35% of total diet energy content (Food and Nutrition Board, 2005). Saturated fatty acid (SFA) content must be as low as possible whilst consuming a nutritionally adequate diet. Polyunsaturated fatty acids (PUFA) must represent a maximum of 10% of total calories and monounsaturated fatty acids (MUFA) should be the main components.
