The objective of this study was to gather information that relates Chia seed composition to the prevention, treatment and control of some pathologies, such as obesity, dyslipidemia, cardiovascular disease and diabetes. This review study used the databases Medline/Pubmed, Lilacs, Scielo, a bibliographic collection of the Federal University of Campina Grande and materials from the national and international health committees, from articles published in the last 20 years. Sixty references were found, of which 43 were included in this study, excluding only those that did not have relevant aspects of the proposed theme. Therefore, when adding Chia seeds to the diet, it is possible to notice an improvement in parameters such as blood pressure (BP), lipid profile, glycemic index (GI), increased satiety sensation and delayed gastric emptying, which are direct indicators of these diseases And consequently the quality of life.
