    This work analyzed the fatty acid composition of mature milk samples, weekly obtained from eight Brazilian women between the 4th and 13th lactation weeks. A questionnaire was weekly applied to observe their eating habits. Saturated fatty acids constituted 39.7% of the total fatty acids. De novo fatty acids and long chain saturated fatty acids presented levels of 15.9% and 23.8%, respectively. trans-Fatty acid content was very low (2.36%). Unsaturated fatty acids constituted 50.9% of the total fatty acids, with over half being monounsaturated fatty acids (27.6%). Polyunsaturated fatty acids showed levels of 23.3%, with high linoleic and α-linolenic acid contents (20.3% and 1.43%, respectively). Arachidonic acid had a content of 0.53%, while docosahexaenoic acid content was 0.14%, values considered adequate for the needs of breast-fed infants.
