-* Soy products
+For comparison: The spermidine content in human seminal plasma varies between approx. 15 and 50 mg/L (mean 31 mg/L).<ref>{{citation|editor-surname1= Ciba-Geigy|periodical=Wissenschaftliche Tabellen Geigy|title=Sperma|edition=8|volume=Teilband Körperflüssigkeiten|publisher=CIBA-GEIGY Limited|location=Basel|at=pp.&nbsp;181-189|date=1977|language=de

+In grains, the [[endosperm]] contains most of the spermidine. One of the best known grain dietary sources is [[wheat germ]], containing as much as 243&nbsp;mg/kg.<ref name=":0">{{cite web|url=http://www.oryza.co.jp/html/english/pdf/polyamine_vol.2.pdf|title=Brochure on Polyamines, rev. 2|publisher=Oryza Oil & Fat Chemocial Co., Ltd.|location=Japan|date=2011-12-26|access-date=2013-11-06}}</ref>
 Considering a balanced diet that includes these foods can increase spermidine intake, which, in light of recent research, could be beneficial for health and longevity.
