Reference Feldman JM, Lee EM. Serotonin content of foods: effect on urinary excretion of 5-hydroxyindoleacetic acid. Am J Clin Nutr. 1985 Oct42(4):p.641 table 2PubMed ID2413754
Method Diagnosis of quantitative urinary excretion of 5-hydroxyindoleaceticacid (5-HIAA, the principal metabolite of serotonin),
Comments P.640 right column 2nd paragraph: "Table 2 shows that all of the nuts in the walnut and hickory families had an extremely high serotonin concentration. There was no difference in the serotonin concentrations of English walnuts and pecans in the shell as compared to the serotonin concentration of these nuts packaged after removal from the shell indicating that the serotonin concentration was probably relatively stable even after shelling."
