Key takeaways:
- Elevated fiber consumption was linked to decreased odds of stroke and all-cause loss of life.
- Dietary fiber was additionally particularly linked to decreased odds of small-vessel stroke.
Elevated dietary fiber was related to decreased probability of stroke, particularly small-vessel stroke, along with decreased all-cause mortality and improved poststroke survival, researchers reported.
Knowledge on the hyperlink between each day dietary fiber consumption and odds of stroke and opposed stroke outcomes have been revealed in Stroke.

“Weight loss program is a vital modifiable think about stroke prevalence, assuming a pivotal function in stroke prevention and administration. Growing proof helps the view that larger dietary fiber consumption can scale back the danger of stroke. Nonetheless, no research have but established a causal relationship between dietary fiber and completely different subtypes of stroke,” Siran Lai, MM, of the First Medical Medical School of Guangzhou College of Chinese language Medication in Guangzhou, China, and colleagues wrote. “We rigorously evaluated the potential associations and causal relationships between dietary fiber consumption and stroke.”
The evaluation included individuals within the Nationwide Well being and Vitamin Examination Survey from 1999 to 2018 who self-reported receiving a earlier prognosis of stroke from a well being care skilled.
Fiber consumption was assessed based mostly on people’ 24-hour dietary recall survey, and researchers utilized the Meals Composition Desk to quantify grams of fiber inside each day nutrient consumption.
Inside a cohort of 39,010 NHANES individuals (imply age, 47 years), 1,453 self-reported stroke (imply age, 64 years).
The common dietary fiber consumption within the total cohort was 16.64 g per day. Within the self-reported stroke group, the imply dietary fiber consumption was 14.33 g per day.
Individuals have been then categorized into one among three tertiles of each day fiber consumption: lowest tertile of 10.9 g or much less; center tertile of 10.9 g to 18.3 g; and highest tertile of 18.3 g or extra.
In contrast with the bottom tertile, people within the highest tertile of each day fiber consumption had decrease odds of stroke (OR = 0.71; 95% CI, 0.57-0.88; P = .002), in line with the examine.
The center tertile of fiber consumption additionally had decreased threat for stroke in contrast with the bottom tertile (OR = 0.81; 95% CI, 0.68-0.96; P = .02), the researchers discovered.
Cox regression and Kaplan-Meier fashions confirmed larger dietary fiber consumption was related to decreased odds of all-cause mortality (OR = 0.68; 95% CI, 0.47-0.97; P = .04) and elevated survival after stroke (P = .023), respectively.
Furthermore, people within the highest tertile of genetically mediated dietary fiber consumption additionally had decrease odds of small-vessel stroke vs. the bottom tertile (OR = 0.83; 95% CI, 0.71-0.98; P = .031).
“Our examine exhibited a strong damaging relationship between dietary fiber consumption and the incident stroke along with stroke-related all-cause mortality, notably when contemplating total dietary fiber consumption,” the researchers wrote. “Given the widespread insufficiency in dietary fiber consumption, it’s crucial to reinforce fiber consumption amongst stroke survivors. To conclusively verify whether or not an elevated dietary fiber consumption actually diminishes the danger of mortality following a stroke, future randomized managed trials are indispensable.”
