How it’s made and used

Protein and amino acids4
Buttermilk has less of the amino acids your body needs than skim milk does.
-
Fat burning in the body5
In lab studies, some buttermilk samples changed how brown fat cells grew and made a heat protein.
The signal at the top counts the findings in people and in animal and lab studies. A concern in studies of people outranks animal and lab studies, and “No concerns” needs at least two findings in people. Findings whose study type is not stated are shown but not counted. This page is a reference, not medical advice. It describes what regulators and published research say. Talk to a doctor or dietitian about your own diet.
