New report: Preventing Cognitive Decline and Dementia: A Way Forward.

The National Institute on Aging (NIA) initiated this study with the National Academies of Sciences, Engineering, and Medicine to take stock of the current state of knowledge on interventions for preventing cognitive decline and dementia, to help shape the messages NIA conveys to the broader public about these conditions, and to inform future actions and research in this area.

Extra-virgin olive oil preserves memory, protects brain against Alzheimer's.

Western diet increases Alzheimer's pathology in genetically predisposed mice.

June 12, 2017

The authors found that APOE4-carrying mice fed a Western-like diet high in saturated fat and sugars for 12 weeks had increased deposits of β-amyloid protein as well a greater number of glial cells, characteristic of Alzheimer's disease (AD). These changes were not observed in mice carrying APOE3, which could mean that carriers of APOE4 are more susceptible to the effects of obesity on AD. ScienceDaily.

New report: Nutrition Across the Lifespan for Healthy Aging: Proceedings of a Workshop.

May 19, 2017

The National Academies of Sciences, Engineering, and Medicine’s Food Forum convened a workshop with five objectives: 1) to examine trends and patterns in aging and factors related to healthy aging in the United States with a focus on nutrition; 2) to examine how nutrition can sustain and promote healthy aging, not only in late adulthood, but beginning in pregnancy and early childhood and extending throughout the lifespan; 3) to highlight the role of nutrition in the aging process at various stages in life; to discuss changes in organ systems over the lifespan, including the skeletal, muscular, and cardiovascular systems, and changes that occur with age related to cognitive, brain, and mental health; 4) diet-related sensory preferences, oral health, and the microbiome; and 5) to explore opportunities to move forward in promoting healthy aging in the United States.
