Almonds,　which　are　excellent　sources　of　some　phytochemicals,　are　the　most　consumed　tree　nut.　In　this　study　healthy　adult　humans　were　recruited　to　evaluate　the　effects　of　almond　and　almond　skin　supplementation　on　serum　lipid　levels,　antioxidant　capacity　and　Yin　-Yang　status　of　the　volunteers.　Under　strict　dietary　control,　a　total　of　48　healthy　adult　volunteers　consumed　a　daily　dose　of　commercial　fructooligosaccharides(8　g),　almonds　(56　g)　or　almond　skins　(10　g)　for　6　weeks.　The　changes　of　the　serum　biomarkers　were　observed.　The　results　indicated　that,　the　body　weights　were　not　increased,　serum　cholesterol　and　triglyceride　declined,　serum　SOD　levels　of　volunteers　consumed　almonds　and　serum　SOD,　GSH-Px　and　T-AOC　levels　of　volunteers　consumed　almond　skins　were　increased　significantly,　and　the　serum　lipid　peroxide　level　of　the　volunteers　consumed　almonds　or　almond　skins　declined.　So　almond　and　almond　skin　supplementation　can　improve　the　serum　lipid　profile　and　enhance　serum　antioxidant　capacity.　It　was　also　found　that,　almond　supplementation　for　6　weeks　would　increase　the　serum　NE　and　cAMP　levels　so　almond　(but　not　almond　skin)　ingestion　may　provoke　volunteers＇　Yangstatus　symptoms,　which　suggested　almonds　were　with　warm　nature.　©　2015,　Editorial　Office　of　Journal　of　CIFST.　All　right　reserved.
