A healthier diet is linked with a slower pace of aging, reduced dementia risk, study shows
A healthier diet is associated with a reduced dementia risk and slower pace of aging, according to a new study at Columbia University Mailman School of Public Health and The Robert Butler Columbia Aging Center. The findings show that a diet-dementia association was at least partially facilitated by multi-system processes of aging. While literature had […]
Fasting-like diet lowers risk factors for disease, reduces biological age in humans
Cycles of a diet that mimics fasting can reduce signs of immune system aging, as well as insulin resistance and liver fat in humans, resulting in a lower biological age, according to a new USC Leonard Davis School of Gerontology-led study. The study, which appears in Nature Communications on Feb. 20, adds to the body […]
Taurine may be a key to longer and healthier life
A deficiency of taurine — a nutrient produced in the body and found in many foods — is a driver of aging in animals, according to a new study led by Columbia researchers and involving dozens of aging researchers around the world. The same study also found that taurine supplements can slow down the aging […]
Eat right, live longer: Could a moderate protein diet be the coveted elixir of youth? Researchers decode the correlation between dietary protein intake and improved metabolic health in mice
Consuming nutritious food can improve metabolic health and delay aging. But what are the appropriate quantities of dietary macronutrients that can help achieve this? To answer this, researchers from Japan fed isocaloric diets with varying amounts of protein to young and middle-aged male mice. They found that the mice were metabolically healthier when fed moderate-protein […]
Number of U.S. Cancer Survivors Grows to 18 Million
A growing — and aging — population, combined with advances in early detection and treatment, pushed the number of cancer survivors to new heights this year. More than 18 million Americans with a history of cancer, two-thirds of them over the age of 65 years, were living in the U.S. as of January 1 of […]
Stimulating brain circuits promotes neuron growth in adulthood, improving cognition and mood
We humans lose mental acuity, an unfortunate side effect of aging. And for individuals with neurodegenerative conditions such as Alzheimer’s and Parkinson’s, the loss of cognitive function often accompanied by mood disorders such as anxiety is a harrowing experience. One way to push back against cognitive decline and anxiety would be to spur the creation […]
New target may help protect bones as we age
Drugs we take like prednisone can weaken our bones and so can aging, and scientists working to prevent both have some of the first evidence that the best target may not be the logical one. They are finding that in aging bone, the mineralocorticoid receptor, better known for its role in blood pressure regulation, is […]
Microglial methylation ‘landscape’ in human brain: Profiles differ across age, disease state, brain region
In the central nervous system, microglial cells play critical roles in development, aging, brain homeostasis, and pathology. Recent studies have shown variation in the gene-expression profile and phenotype of microglia across brain regions and between different age and disease states. But the molecular mechanisms that contribute to these transcriptomic changes in the human brain are […]
MIND diet linked to better cognitive performance: Study finds diet may contribute to cognitive resilience in the elderly
Aging takes a toll on the body and on the mind. For example, the tissue of aging human brains sometimes develops abnormal clumps of proteins that are the hallmark of Alzheimer’s disease. How can you protect your brain from these effects? Researchers at Rush University Medical Center have found that older adults may benefit from […]
