Porcini mushrooms (shown here) are the richest source of two major antioxidants. A new study published in the journal Food Chemistry suggests that certain mushrooms contain two antioxidants thought to improve healthspan and stave off aging. The new research was led by Robert Beelman, professor emeritus of food science and director of the Pennsylvania State University Continue Reading

What is the link between sleep apnea and neurodegenerative conditions? Researchers investigate. A new study has demonstrated that older adults who experience obstructive sleep apnea may be at increased risk of Alzheimer’s disease. This is because they exhibit higher levels of amyloid beta, the chief component of the amyloid plaques that characterize the disease. Obstructive Continue Reading

What is the link between heart health and brain health? New research based on a large longitudinal study has revealed that reduced blood flow from the heart in old age also leads to poorer circulation in the temporal lobes of the brain, which constitute our memory “hub.” A study led by researchers at Vanderbilt University in Nashville, TN — Continue Reading
