Kefir Is A Viable Exercise Recovery Beverage For Cancer Survivors Enrolled In A Structured Exercise Program

Effect Decrease
Values After 12 wks exercise, kefir group saw a 22.3% decrease in the percentage of non-classical monocytes, compared to 30.4% increase in control.
Trial Design Non-randomized controlled trial
Trial Length 1-6 months
Number of Subjects 24
Sex Both Genders
Age Range 30-44, 45-64, 65+
Notes for this study:
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).

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.
