The Claim
Daily consumption of 4 grams of dried laver (Porphyra tenera) for 12 weeks is associated with increased gut microbial alpha diversity, as measured by Chao1 and Fisher indices, in older women aged 50 and above.
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 aged 50 and above, eating 4 grams of dried laver every day for 12 weeks is linked to higher gut microbial diversity, measured by Chao1 and Fisher indices.
See the scientific wording
Daily consumption of 4 grams of dried laver (Porphyra tenera) for 12 weeks is associated with increased gut microbial alpha diversity, as measured by Chao1 and Fisher indices, in older women aged 50 and above, suggesting a potential prebiotic effect on microbial richness and evenness.
The undigested seaweed fibers reach the colon and feed specific bacteria that break them down into acids. These acids change the gut environment, killing harmful bacteria and helping good bacteria grow. As more types of good bacteria thrive and work together, the overall variety and balance of the gut microbiome increases.
What the research says
1 studyEating a small amount of dried laver every day for three months made the good bacteria in the guts of older women more varied and balanced, which is a sign of a healthier gut.
