The Claim

Consumption of 400 grams per day of live-fermented yogurt for 16 weeks increases plasma citrate concentration in middle-aged men with abdominal obesity, whereas heat-treated yogurt and acidified milk do not produce this increase.

Cause and effect
1 study reviewed
In plain English

Middle-aged men with abdominal obesity who consume 400 grams of live-fermented yogurt daily for 16 weeks show higher plasma citrate levels than those who consume heat-treated yogurt or acidified milk.

See the scientific wording

Consumption of 400 grams per day of yogurt for 16 weeks increases plasma citrate concentration in middle-aged men with abdominal obesity, suggesting altered mitochondrial metabolism or citrate transport, but this effect is not observed with heat-treated yogurt or acidified milk, indicating a unique response to live-fermented dairy.

Why this might work

Live bacteria in yogurt break down milk sugars into lactate, which travels to the colon and gets turned into other compounds that signal the liver to produce more citrate. This citrate enters the blood, but only when live bacteria are present — heat-killed yogurt or sour milk don’t do this because they lack the living microbes needed to trigger the signal.

What the research says

1 study
  1. Study: Changes in Plasma, Urine, and Fecal Metabolome after 16 Weeks of Consuming Dairy With Different Food Matrixes - A Randomized Controlled Trial.

    Eating regular yogurt with live bacteria raised a substance called citrate in the blood of men with belly fat, but eating yogurt that was cooked or milk that was just made sour didn’t do this — so it’s the live bacteria in yogurt, not just the milk, that causes the change.
