Kefir Is A Viable Exercise Recovery Beverage For Cancer Survivors Enrolled In A Structured Exercise Program
Notes for this study:
||After 12 wks exercise, kefir group saw an 18% increase in the percentage of monocytes that were classical, compared to a 4.4% decrease in control.
||Non-randomized controlled trial
|Number of Subjects
||30-44, 45-64, 65+
24 cancer survivors, who had undergone chemotherapy and/or radiation at most 2 years previously, did 12 weeks of an exercise regimen (60 minute sessions 3x-week). Half the patients were given kefir to drink after each exercise session, and half were given nothing (control).
Funding issues for this study:
Kefir consumption was associated with improvements in lean body mass, depression, fatigue, and gastric distress. The 12 participants who took kefir also saw significant reduction in circulating lipopolysaccharides, increase in proportion of classical monocytes and decrease in proportion of non-classical monocytes.
There was no milk control in this study, so we don't know whether these effects could have been seen with low-fat milk. The kefir in this study was commercial low-fat American kefir, prepared by Lifeway Foods Inc.
