Want a younger brain? Stay in school — and take the stairs [news release]

From the 9th March 2016 Concordia University news release

A Concordia study shows that education and physical activity can significantly slow down grey-matter aging

Montreal, March 9, 2016 — Taking the stairs is normally associated with keeping your body strong and healthy. But new research shows that it improves your brain’s health too — and that education also has a positive effect.

In a study recently published in the journal Neurobiology of Aging, researchers led by Jason Steffener, a scientist at Concordia’s PERFORM Centre, show that the more flights of stairs a person climbs, and the more years of school a person completes, the “younger” their brain physically appears.

The researchers found that brain age decreases by 0.95 years for each year of education, and by 0.58 years for every daily flight of stairs climbed — i.e., the stairs between two consecutive floors in a building.

“There already exist many ‘Take the stairs’ campaigns in office environments and public transportation centres,” says Steffener. “This study shows that these campaigns should also be expanded for older adults, so that they can work to keep their brains young.”

CAPTION
Journal of Medicinal Food is an authoritative, peer-reviewed, multidisciplinary journal published monthly in print and online. Led by Editors-in-Chief Sampath Parthasarathy, MBA, PhD, and Young-Eun Lee, PhD, Wonkwang University, Jeonbuk, Korea, this scientific journal publishes original scientific research on the bioactive substances of functional and medicinal foods, nutraceuticals, herbal substances, and other natural products. The Journal explores the chemistry and biochemistry of these substances, as well as the methods for their extraction and analysis, the use of biomarkers and other methods to assay their biological roles, and the development of bioactive substances for commercial use. Tables of content and a sample issue may be viewed on the Journal of Medicinal Food website.

New Rochelle, NY, January 21, 2015–The hundred trillion bacteria living in an adult human–mostly in the intestines, making up the gut microbiome–have a significant impact on behavior and brain health. The many ways gut bacteria can impact normal brain activity and development, affect sleep and stress responses, play a role in a variety of diseases, and be modified through diet for therapeutic use are described in a comprehensive Review article in Journal of Medicinal Food, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers. The paper is available free on the Journal of Medicinal Food website until February 21, 2015.

In “The Gut Microbiome and the Brain”, Leo Galland, Foundation for Integrated Medicine (New York, NY), presents the most up-to-date understanding of the relationship between the proteins produced by intestinal bacteria and the human central nervous system. The author explores the various mechanisms through which the microbiome can influence the brain: by stimulating and over-stimulating the immune system, producing neurotoxic agents, releasing hormones or neurotransmitters identical to those made by the human body, or through direct neuronal stimulation that sends signals to the brain.

“The microbiome has become a hot topic in many branches of medicine, from immune and inflammatory diseases, such as Crohn’s and IBD to cardiovascular diseases,” says Co-Editor-in-Chief Sampath Parthasarathy, MBA, PhD, Florida Hospital Chair in Cardiovascular Sciences, University of Central Florida, Orlando. “Scientists are not only aware of the ‘good’ and the ‘bad’ microbes in the gut but are becoming increasingly aware of how they could alter the metabolism beyond gut.”
