New Study Examines the Effects of Food Insecurity on Dementia Risk

Posted on

The latest Household Food Security report estimated that 13.7% of U.S. households experienced food insecurity in 2024. This lack of access to a nutritious diet can significantly affect health, so how does it then impact older adults’ health and their risk for cognitive impairment? Dr. Heejin Lee joins the podcast to share what food insecurity means, how it can affect a person’s overall health and what her study found about its effect on dementia and cognitive impairment, as well as resources for those experiencing food insecurity.

How Ultra‑Processed Foods Impact Your Overall Health

Posted on

Ultra-processed foods are a hot topic in the fields of health and nutrition, but what exactly are they and how do they impact our overall well-being? Dr. Beth Olson joins the podcast to explain what this term means, describe strategies for developing a balanced diet and share a preview of her upcoming Healthy Living with Mild Cognitive Impairment (MCI) presentation, “Unpacking Ultra-Processed Foods.”

A Pathway to Wellness: The Benefits of Integrative Medicine on Brain Health

Posted on

Holistic medicine, alternative medicine, complementary medicine – you may have heard these terms or seen them used online and wondered what they mean. Each term refers to the concept of integrative medicine, a comprehensive approach to healthcare that focuses on treating a person’s mind, body and spirit rather than addressing symptoms or a specific disease through a combination of medical treatments and other evidence-based therapies. By integrating practices like nutrition, mindfulness, supplements and other alternative therapies with traditional care, integrative medicine aims to promote overall wellness, enhance healing and improve quality of life, especially for individuals managing chronic conditions like dementia. Dr. David Rakel, a leader in integrative medicine, joins the podcast to share about how this holistic approach can help people experiencing memory change and how diet, mindset and lifestyle can play a crucial role in supporting brain health.

Gut Feelings: The Links Between Gut Health and Alzheimer’s Disease

Posted on

An expanding field of research is looking at how the gut affects different parts of people’s health, but how does it affect brain health? Drs. Barb Bendlin and Tyler Ulland join the podcast to talk about their 2023 study, which suggests a link between gut health, aging and changes related to Alzheimer’s disease. They discuss their findings on how gut inflammation could impact brain health, as well as explain what it means to have good gut health and how food, medications, where one lives and other factors can impact the gut microbiome.

Guests: Barbara Bendlin, PhD, professor, Division of Geriatrics and Gerontology, deputy director, University of Wisconsin (UW) Center for Health Disparities Research, and Tyler Ulland, PhD, associate professor of pathology and laboratory medicine, UW School of Medicine and Public Health, leader, Ulland Lab

Reviewing the Six Pillars of Brain Health

Posted on

In this compendium episode, we review some of the best information and research that we’ve shared on the six pillars of brain health. With excerpts highlighting the importance of physical activity, diet, sleep, social engagement and more, our six guests show that there are numerous evidence-based lifestyle interventions that a person can incorporate into their daily lives to improve their brain health and delay the onset of or reduce their risk of developing Alzheimer’s disease.

Take Care of Your MIND: Reviewing the MIND Diet for Healthy Brain Aging

Posted on

To mark National Mediterranean Diet Month, Dr. Nathaniel Chin discusses a recent National Institute on Aging-funded study that suggests the MIND and Mediterranean diets — both rich in vegetables, fruits, whole grains, olive oil, beans and fish — are associated with fewer signs of Alzheimer’s disease in the brains of older adults. In this special episode of Dementia Matters, Chin also revisits his interview with the creator of the MIND diet, Dr. Martha Clare Morris, shares recommendations for ten things to incorporate into your diet and five things to limit, and touches on the benefits of intermittent fasting.

Alcohol and the Brain: One Drink a Day Associated with Brain Shrinkage

Posted on

There are many conflicting studies on how alcohol consumption can impact a person’s health, with some studies suggesting light drinking can protect against coronary heart disease and others concluding that drinking can increase your risk for cancer. What does research say about alcohol and the brain? Dr. Remi Daviet joins the podcast to discuss his latest study that found that just one alcoholic drink a day was associated with brain shrinkage, and drinking more could increase that rate exponentially over time.

New Research Shifts Thinking on Metabolism and Aging

Posted on

There are many common beliefs about metabolism. Perhaps you’ve heard that a person’s metabolism slows around middle age, or that a woman’s metabolism is slower than a man’s. However widespread these beliefs are, recent research from the journal Science has found that these conceptions of metabolism are wrong. In a groundbreaking study, researchers have found that metabolism goes through four key phases over our lives, only beginning to slow around age 60. This, among other findings, are now changing how we think about human physiology and how we think about aging. Breaking down this new research and his perspective article on the findings, Dr. Rhoads describes our shifting understandings of metabolism and how it impacts chronic diseases like Alzheimer’s disease as we age.

You Are What You Eat: Study of Diet and Brain Health Shows Cognitive Benefits from Cheese, Wine and Lamb

Posted on

A recent study of nearly 1,800 participants from the UK Biobank found that three dietary elements — cheese, wine, and lamb — may improve long-term cognitive outcomes in aging adults. Dr. Auriel Willette, assistant professor of food science and human nutrition at Iowa State University, joins the podcast to discuss these new findings linking diet and cognitive changes. In November 2020, Willette published a study in the Journal of Alzheimer’s Disease titled, “Genetic Factors of Alzheimer’s Disease Modulate How Diet is Associated with Long-Term Cognitive Trajectories: A UK Biobank Study,” where he and his team studied the effects of particular foods on a person’s brain health over time. As well as the findings surrounding cheese, wine, and lamb, they found that limiting salt intake was good for the brain, especially for those at risk for Alzheimer’s disease. Discussing the field of nutritional research, his prior work studying diet and brain health, and how these findings impact other recommended diets, Willette provides insight into how our current diets can impact our health and cognitive abilities later in life, allowing us to make better choices for the future.
