Perfil fitoquímico, nutricional e medicinal do alho (Allium sativum L.): uma revisão narrativa de literatura

Abstract

Garlic (Allium sativum L.) is a vegetable rich in starch and aromatic substances of high flavoring value and has phytotherapeutic action with several pharmacological properties. Its potential benefits mostly affect the immune and cardiovascular systems. The protective effects can be attributed to its bioactive compounds such as phenolic and organosulfur compounds, in addition to phytosterols that can contribute to the antioxidant and lipid-lowering effects. However, garlic may have changes in the amount and effectiveness of its bioactive compounds. Therefore, the objective of this study was to search the literature for studies related to garlic, seeking to establish a correlation between its phytochemical profile and a possible therapeutic and/or nutritional activity. The method is a broad narrative literature review that proposes to describe the development of a given subject, from a theoretical or contextual point of view, through existing scientific analysis and interpretation. It consists, basically, of an analysis of the literature published in books, articles in printed and/or electronic magazines, in the interpretation and personal critical analysis of the author. There is a need to encourage research aimed at the nutritional therapeutic activities of garlic as a potential food.
