Human in vivo study of the renin-angiotensin-aldosterone system and the sympathetic activity after 8 weeks daily intake of fermented milk.

Objective: Milk fermented by lactic acid bacteria is suggested to have antihypertensive effect in humans. In vitro and animal studies have established an angiotensin-converting enzyme (ACE) inhibitor effect of peptides in fermented milk. However, other modes of action must be considered, because until today no human studies have confirmed an ACE inhibition in relation to the intake of fermented milk.
