Low dietary fiber intake could lead to high cardiovascular risk
Washington: A new study has shown a link between low dietary fiber intake and cardiometabolic risks including metabolic syndrome, cardiovascular inflammation, and obesity.
Surveillance data from 23,168 subjects in the National Health and Nutrition Examination Survey (NHANES) 1999-2010 was used to examine the role dietary fiber plays in heart health.
In the current study investigators have taken a closer look at possible sex, age, racial/ethnic, and socioeconomic disparities in dietary fiber consumption, as well as examined the association between dietary fiber intake and various cardiometabolic risk factors.
Senior investigator Cheryl R. Clark, MD, ScD, Center for Community Health and Health Equity, Brigham and Women's Hospital and Harvard Medical School, Boston, said that their study also confirms persistent differences in dietary fiber intake among socioeconomic status and racial/ethnic subpopulations over time.
The research team found variations according to race and ethnicity, with Mexican-Americans consuming higher amounts of dietary fiber and non-Hispanic blacks consuming lower amounts of dietary fiber compared with non-Hispanic whites.
The study highlights the importance of increasing dietary fiber intake for US adults by showing a correlation between low dietary fiber and an increased risk for cardiovascular risk. Participants with the highest prevalence of metabolic syndrome, inflammation, and obesity were in the lowest quintile of dietary fiber intake.
The new study has been published in The American Journal of Medicine.
