Maîtriser son taux de cholestérol | Fondation des maladies du cœur et de l’AVC

Le taux de cholestérol est dans le sang. On retrouve deux types principaux de cholestérol sanguin : celui de haute densité, ou HDL, et celui de faible densité, ou LDL.
Le cholestérol LDL est celui qu’on dit « mauvais » : s’il est présent en trop grande quantité, il peut former des plaques et des dépôts gras sur les parois des artères, et ainsi empêcher le sang de circuler jusqu’au cœur et au cerveau.
Le HDL, en comparaison, est « bon », car il permet d’éliminer l’excès de cholestérol que l’on retrouve dans le corps.
