The Claim
Twelve weeks of daily 4-gram dried laver consumption is associated with a reduction in the Firmicutes/Bacteroidetes ratio in older women, with a greater decline observed in those with metabolic syndrome compared to those without.
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.
In older women, consuming 4 grams of dried laver daily for 12 weeks is linked to a lower Firmicutes/Bacteroidetes ratio in gut bacteria, with a stronger reduction in those who have metabolic syndrome.
See the scientific wording
Twelve weeks of daily 4-gram dried laver consumption is associated with a reduction in the Firmicutes/Bacteroidetes ratio in older women, with a greater decline observed in those with metabolic syndrome compared to those without.
When dried laver is eaten, its special fibers pass through the stomach and small intestine without being broken down. In the colon, specific bacteria feed on these fibers and produce short-chain fatty acids. These acids make the colon more acidic, which kills harmful bacteria and helps good bacteria grow. This changes the balance of bacteria so that fewer Firmicutes and more Bacteroidetes are present, especially in people with metabolic syndrome.
What the research says
1 studyEating a small amount of dried seaweed every day for three months changed the gut bacteria in older women, especially those with metabolic syndrome, making the good bacteria more common compared to the less helpful ones — exactly what the claim says.
