The Claim

Consuming a high animal fat diet (approximately 152 grams per day) significantly increases total fecal bile acid excretion to approximately 320 milligrams per day compared to a low animal fat diet (approximately 62 grams per day) in healthy young adults over a four-week period, a physiological change clinically relevant due to the theoretical promotion of large bowel cancer by elevated colonic bile acids.

Source: Influence of diets high and low in animal fat on bowel habit, gastrointestinal transit time, fecal microflora, bile acid, and fat excretion.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Cause and effect
1 study reviewed
In plain English

Eating a lot of animal fat makes your body excrete much more bile acid into your stool. This matters because too much bile acid in the colon is thought to increase the risk of developing bowel cancer.

See the scientific wording

Consuming a high animal fat diet (approximately 152 grams per day) compared to a low animal fat diet (approximately 62 grams per day) significantly increases total fecal bile acid excretion to approximately 320 milligrams per day, compared to approximately 140 milligrams per day, in healthy young adults over a four-week period, which is clinically relevant because elevated colonic bile acids are theorized to promote large bowel cancer development.

What the research says

1 study
  1. Study: Influence of diets high and low in animal fat on bowel habit, gastrointestinal transit time, fecal microflora, bile acid, and fat excretion.

    Eating a lot of animal fat makes your body excrete much more bile acid in your stool compared to eating less animal fat. This matters because high levels of bile acid in the colon are thought to increase the risk of bowel cancer.
