Human <i>in vivo</i> study of the renin–angiotensin–aldosterone system and the sympathetic activity after 8 weeks daily intake of fermented milk

Abstract

Despite a known ACE inhibitory effect in vitro and in animals, milk fermented with Lb. helveticus did not inhibit ACE in humans. Our results suggest that the intake of fermented milk decreases sympathetic activity, although not to an extent mediating reductions of blood pressure and heart rate in borderline-hypertensive subjects.
