LSUHealthNO Research Finds Walnuts May Promote Health by Changing Gut Bacteria
Research led by Lauri Byerley, PhD, RD, Research Associate Professor of Physiology at LSU Health New Orleans School of Medicine, has found that walnuts in the diet change the makeup of bacteria in the gut, which suggests a new way walnuts may contribute to better health. The findings are published in The Journal of Nutritional Biochemistry available online.
“We found that walnuts in the diet increased the diversity of bacteria in the gut, and other non-related studies have associated less bacterial diversity with obesity and other diseases like inflammatory bowel disease,” says Byerley. “Walnuts increased several bacteria, like Lactobacillus, typically associated with probiotics suggesting walnuts may act as a prebiotic.”
Prebiotics are dietary substances that selectively promote the numbers and activity of beneficial bacteria.
“Gut health is an emerging research area, and researchers are finding that greater bacterial diversity may be associated with better health outcomes,” adds Byerley.
Top Story on VAntage Point :
Dr. Nicholas Gilpin, who recently was awarded a research grant from VA, is working to identify the neurobiological mechanisms in underlying heightened pain states in the context of alcohol dependence and stress disorders. Gilpin and his staff are working to develop therapeutic strategies that reduce pain in Veterans living with PTSD and/or alcohol use disorder.
Gilpin's grant will support work to examine the contribution of brain melanocortin-4 (MC4) receptor signaling to pain processing in those living with alcohol dependence or traumatic stress disorders. Our first major data set demonstrates that MC4 receptors modulate heightened pain processing in those living with alcohol dependence, and that we can use this receptor as a therapeutic target, he said. Next, our plan is to drill deeper to understand how and where this receptor interrupts brain circuits. That will be a major step toward understanding how MC4 receptors may potentially be targeted to improve Veterans lives.
Preventing Abuse & Treating Addiction, in Louisiana and Beyond
Alcohol and drug abuse take a tremendous toll on our society at many levels, and Louisiana is no exception, ranking among the highest in the nation for consumption and abuse of alcohol and drugs. Approximately 10% of Louisiana residents have a diagnosable alcohol use disorder and 5% use illicit drugs. Outdated estimates from 1998 place the economic cost of alcoholism in Louisiana at $3 billion annually and the cost of illicit drug addiction at $193 billion per year nationally.
The LSU Health Alcohol and Drug Abuse Center of Excellence (ADACE) is working on a number of fronts to combat issues related to addiction and abuse. The mission of the ADACE is to enhance the research capabilities of scientists, stimulate collaborative research efforts, and strengthen educational activities related to the biomedical aspects of alcohol and substance abuse. Dr. Patricia Molina and her team work together to find solutions to alcohol and drug addiction.

"Our projects have a positive economic impact on Louisiana by reducing lost wages, as well as health care and mortality costs associated with alcohol and drug abuse."
