Vitamin C May Help Preserve Brain Gray Matter Volume as We Age
Researchers in Japan found that older adults with low blood‑plasma vitamin C levels have smaller gray‑matter volumes and reduced connectivity in the brain’s default mode network. The cross‑sectional study evaluated MRI scans and plasma samples from about 2,000 participants aged 64 and older. While the findings suggest vitamin C may support brain structural integrity, the authors caution that causality has not been proven. Further longitudinal and interventional studies are planned to test whether boosting vitamin C can slow age‑related cognitive decline.
An Avocado a Day May Help Control Blood Sugar, Study Claims
A secondary analysis of the Habitual Diet and Avocado Trial found that participants who ate one large avocado each day for six months experienced a lower dietary glycemic load than a control group. The study involved 961 overweight or obese...
B12, Folate Supplements May Be Key to Tackling Chronic Fatigue
Researchers at Osaka University analyzed data from 2,618 adults and found that elevated blood homocysteine—a marker of vitamin B12 and folate deficiency—was associated with higher physical fatigue in men and lower motivation in women. The cross‑sectional study, published in Nutrients,...
When Should You Get a Mammogram to Screen for Breast Cancer? Experts Clarify
The American College of Physicians issued new 2026 breast‑cancer screening guidance that revises age, frequency, and supplemental imaging recommendations, sparking fresh debate with the U.S. Preventive Services Task Force’s 2024 advice. The USPSTF now recommends starting mammograms at age 40 and...
Combination Therapy Sustains 49% Melanoma Reduction After 5 Years
A phase 2b KEYNOTE‑942 trial presented at ASCO 2026 shows that a personalized mRNA melanoma vaccine (intismeran autogene) combined with Merck’s Keytruda dramatically improves outcomes. Five‑year overall survival reached 92.2% versus 71.3% with Keytruda alone, and the risk of distant metastasis...
Alzheimer’s Blood Test Around Ages 53-69 May Help Detect Early Cognitive Decline
Researchers published in The Lancet that blood tests detecting amyloid‑beta and tau can identify early cognitive decline in adults aged 53‑69. In a cohort, 6% showed elevated biomarkers and subsequently exhibited slower processing speed, with a 2.5‑4‑fold higher risk of...
Could Giving up High-Sugar, High-Fat Diets Help Reverse Cognitive Damage?
A review of 27 rodent studies published in Nutritional Neuroscience finds that high‑sugar diets can cause lasting cognitive impairment that is only partially reversible. Switching to a healthier diet improves memory in animals previously fed high‑fat diets, but not in...
How Exercise Boosts Longevity, Prolongs the Health Span: Latest Evidence
Recent research underscores exercise as a critical lever for healthy aging. A PNAS study revealed that aerobic and resistance workouts trigger FOXO genes, counteracting DEAF1‑driven muscle decline. A six‑month trial with adults averaging 72 showed high‑intensity interval training (HIIT) uniquely...
Declining Physical Activity May Signal Cognitive Changes in Older Adults
A 17‑year UK cohort study of 2,529 adults aged 50 and older found that greater memory decline is linked to less light physical activity and more sedentary time. Participants with slower memory loss logged roughly 14 extra minutes of light...
Giving up Smoking Linked to 16% Lower Dementia Risk
A longitudinal analysis of 32,802 U.S. adults found that quitting smoking lowers dementia risk by 16% compared with continued smoking. The protective effect strengthens over time, aligning with never‑smokers after roughly seven years of abstinence. Participants who gained little or...
How Vitamin D in Pregnancy Could Offer a Head Start for Better Cognitive Health
A secondary analysis of the Copenhagen Prospective Studies on Asthma in Childhood 2010 trial found that pregnant women who took a high dose of 2,800 IU vitamin D₃ daily from week 24 to postpartum had children with stronger visual memory, verbal...
Even 'Silent' Heart Attacks Could Speed up Cognitive Decline
Researchers have found that silent myocardial infarctions—heart attacks that go undiagnosed—accelerate cognitive decline as much as clinically recognized attacks. In a biracial cohort of 2,183 participants with any type of heart attack, follow‑up over 10‑14 years showed a higher likelihood...
Immunotherapy Before Surgery May Reduce Colon Cancer Recurrence
A phase II NEOPRISM‑CRC trial at University College London gave 9 weeks of pembrolizumab before surgery to 32 stage 2‑3 colorectal cancer patients with MMR‑deficient/MSI‑high tumors. Fifty‑nine percent achieved no detectable cancer after treatment, and after a median 33‑month follow‑up none experienced recurrence,...
WHO Declares Ebola Global Health Emergency: 6 Things to Know
The World Health Organization on May 17, 2026 declared the Ebola outbreak in the Democratic Republic of the Congo and Uganda a public health emergency of international concern. Health authorities report at least 500 suspected cases, 130 suspected deaths, 30...
Blood Test Measuring Biological Age May Reveal Dementia Risk
Researchers at King’s College London validated a blood‑based metabolomic aging clock that can flag individuals at heightened risk of dementia years before symptoms appear. Participants whose biological age exceeded their chronological age by more than one standard deviation faced a...
