The Claim

Twelve weeks of daily 4-gram dried laver consumption is associated with increased abundance of the genus CAG_873 in older women without metabolic syndrome, a taxon linked to dietary fiber fermentation and short-chain fatty acid production.

In plain English

Daily consumption of 4 grams of dried laver for 12 weeks is associated with higher levels of the gut bacterium CAG_873 in older women without metabolic syndrome. This bacterium is involved in breaking down dietary fiber and producing short-chain fatty acids.

See the scientific wording

Twelve weeks of daily 4-gram dried laver consumption is associated with increased abundance of the genus CAG_873 in older women without metabolic syndrome, a taxon linked to dietary fiber fermentation and short-chain fatty acid production.

Why this might work

When people eat dried laver, a special type of fiber called porphyran passes through the stomach and small intestine without being broken down. It reaches the colon, where certain bacteria break it down and turn it into short-chain fatty acids. These bacteria, including CAG_873, grow stronger and multiply because they can use this fiber as food. As they grow, they crowd out other bacteria that don't use this fiber, and the overall number and variety of good bacteria in the gut increase.

  1. Study: Dietary Dried Laver (Porphyra tenera) Modulates Gut Microbiota Composition and Diversity in Older Women with and Without Metabolic Syndrome: An Exploratory Pilot Study

    The study found that when older women without metabolic syndrome ate 4 grams of dried laver every day for three months, a helpful gut bacterium called CAG_873 increased in their intestines. This matches exactly what the claim says.
