The Claim

Consumption of 400 grams per day of dairy products for 16 weeks has no effect on total fecal short-chain fatty acid concentrations in middle-aged men with abdominal obesity.

Description
1 study reviewed
In plain English

Eating 400 grams of dairy products daily for 16 weeks does not change the total amount of short-chain fatty acids in the feces of middle-aged men with abdominal obesity.

See the scientific wording

Consumption of 400 grams per day of dairy products for 16 weeks does not alter total fecal short-chain fatty acid concentrations in middle-aged men with abdominal obesity, suggesting overall colonic fermentation activity remains unchanged despite shifts in metabolite profiles.

Why this might work

When people eat a lot of dairy, the lactic acid in it makes the small intestine more acidic, which helps break down proteins into amino acids before they reach the gut. This means less protein gets to the colon for bacteria to break down into branched-chain fatty acids. At the same time, the lactic acid that does reach the colon gets used by certain bacteria to make more butyrate instead of acetate. The total amount of fatty acids produced stays the same, but the mix changes because the bacteria switch what they feed on.

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

    People ate 400 grams of dairy every day for 16 weeks, and while the types of gut bacteria byproducts changed, the total amount of these byproducts stayed the same — meaning overall gut fermentation didn’t increase or decrease.
