Notes for this study:
This 12-week study divided participants into kefir and yoghurt (control) groups. The particpating men drank 1.6 mL/kg, and women 1.9 mL/kg, of kefir or yoghurt. Kefir did not affect any anthropometric measures, but the kefir group saw reductions in blood pressure, fasting blood glucose levels, LDL-C, non-HDL cholesterol, triglycerides, and oxidized LDL. Women in the kefir group saw an increase in HDL-C levels. The Framingham Risk Score was lowered in the kefir group, but the level of high-sensitivity C-reactive protein (a measure of inflammation) was unchanged.

The kefir used in this study was prepared in-lab from locally-procured kefir grains, then sweetened and flavoured.
