Clinical Trial Summary

To investigate the impact of consuming dairy yogurt on immun function including natural killer (NK) cell activity, circulating levels of cytokines, and immunoglobulin (Ig) in elderly.


Clinical Trial Description

A randomized, open-labelled, placebo-controlled study was conducted on 200 nondiabetic, nonobese and elderly (≥60 years) subjects. Over a twelve-week period, the test group consumed one bottle (120 mL) of dairy yogurt each day, whereas the placebo group consumed same volume of low fat milk daily. NK cell activity (%) was measured based on the ratios of effector cells (E; peripheral blood mononuclear cells, PBMCs) from each participant to target cells (T; K562 cells) at E:T= 10:1, 5:1, 2.5:1, 1.25:1 or 0.625:1. In addition, cytokines and immunoglobulin levels measured using commercial kits as manufacturer's instruction. ;
