TL;DR: A 2026 pilot trial in PLOS One found that a 7-day chicory-and-green-tea herbal supplement did not improve sleep, quality of life, or objective sleep architecture more than placebo in adults with insomnia. Key Findings Small crossover pilot: The crossover pilot enrolled 10 adults aged 50 years or older with insomnia; 9 were women and …
TL;DR: A 2026 systematic review and meta-analysis in Neurological Sciences found that ketogenic diet (KD), a very-low-carbohydrate diet designed to raise ketone fuel use, looked feasible and generally safe as an add-on strategy in glioblastoma (GBM), but the survival signal still needs phase III randomized proof. Key Findings The review included 41 human studies of …
TL;DR: A 2026 study in Aging Cell found that fasting and caloric restriction activated ADIOL, a steroid hormone, through an NHR-91-kynurenic acid pathway that improved several healthspan measures in worms without extending lifespan. Key Findings ADIOL was the central hormone: 5-androstene-3beta,17beta-diol (ADIOL) linked nutrient restriction to healthier function in C. elegans worms. NHR-91 was required: …
TL;DR: A 2026 study in Journal of Neuroscience found that when people expected sugar, an artificially sweetened drink became more pleasant and produced a stronger midbrain response, even though perceived sweetness was similar. Key Findings Expectation changed the reward readout: The researchers selected participants who reported similar perceptual experiences of sugar and non-nutritive sweetener. 27 …
TL;DR: A 2026 uncontrolled pilot study in BJPsych Open found that SMART, a personalized text-message program for metabolic health in people with schizophrenia spectrum disorders, improved patient activation, diabetes self-management confidence, health literacy, and recovery scores over 12 weeks, while objective cardiometabolic markers did not significantly change. Key Findings SMART reached a schizophrenia-risk group: Researchers …
TL;DR: A 2026 study in Biochemistry and Biophysics Reports found that cannabinoid receptor 1 (CB1R) undergoes autophagy-linked degradation in mouse cortical neurons, but p62 deficiency did not make CB1R the main driver of obesity and low activity in p62 knockout mice. Key Findings CB1R accumulated up to 10-fold: Blocking autophagic flux with Bafilomycin A1 in …
TL;DR: A 2026 case-series study in Translational Psychiatry tested delayed-release oral acetate from apple cider vinegar capsules in 11 young adults taking psychotropic medications and found high adherence, no product-related adverse events, microbiome shifts, and metabolic improvement in 6 participants, but the uncontrolled design means the findings need placebo-controlled testing. Key Findings 11 completers: The …
TL;DR: A 2026 mouse study in Nature found that small-molecule glucagon-like peptide 1 receptor agonists (GLP-1RAs), obesity and diabetes drugs built around a glucose-linked hormone pathway, suppressed palatable-food intake through central amygdala neurons that lowered nucleus accumbens dopamine. Key Findings Humanized mouse model: Researchers engineered mice so small-molecule GLP-1 receptor agonists could be studied despite …
TL;DR: A 2026 biomarker analysis in Brain, Behavior, & Immunity – Health across antidepressant trials found that kynurenine pathway metabolites were elevated in inflammatory depression compared with non-inflammatory depression and healthy controls, while omega-3 polyunsaturated fatty acid treatment reduced several kynurenine pathway metabolites. Key Findings Study type: a combined analysis of two depression trials testing …
TL;DR: A 2026 study in Microbiome found that in older adults at metabolic risk, virgin olive oil was linked to better cognitive preservation and richer gut microbiota, while common refined olive oil pointed the other way. Key Findings Metabolic-risk cohort tracked over time: The analysis followed 656 older adults who were 55-75 years old, cognitively …
