Vanderbilt researchers study link between diet, mortality
ONCE AGAIN WE SEE POWERFU RESEARCH SHOWING IT IS THE DIET MORESO THAN SOCIOECONOMIC LEVEL (ALTHOUGH THEY ARE OF COURSE INTERTWINED) THAT IS THE MAJOR PLAYER- Doc Kevin Ryan
The study used data from the Southern Community Cohort Study that was collected mostly through community health centers serving low-income populations in 12 Southeastern states, according to a statement from the university. More than half of the participants had an annual household income of less than $15,000, and 65 percent were black.
Investigators used the federal government guidelines to assess the healthfulness of the participants’ diets, according to the university. The guidelines emphasize a diet rich in vegetables, fruits, whole grains, seafood, legumes and nuts; moderate in low- or non-fat dairy and alcohol; and low in red and processed meats, sugary foods and drinks, and refined grains.
Past studies have suggested African-Americans and low-income adults have more limited access to healthy foods, but the study’s authors found little existing research on the link between diet and disease mortality.
“These findings present direct evidence that dietary modification may influence disease prevention in this under-served population,” Dr. Wei Zheng, director of the Vanderbilt Epidemiology Center and lead author of the study, said in the statement.
The study was published in the latest issue of the journal PLOS Medicine. Investigators from the International Epidemiology Institute, the Harvard School of Public Health and Meharry Medical College worked alongside the Vanderbilt researchers for the study, which was supported by funding from the National Cancer Institute.
