Can we crack the code on aging, or are humans just “term-limited”? What are some of the most promising anti-aging interventions currently under investigation? We may be curing more cancers, and discovering them earlier, but certain cancers are increasing in incidence, especially among the young; Why extreme old age may be protective against cancer; Big meta-analysis confirms cardio benefits of low-carb diet; Patients with depression who’ve tried everything obtain surprising relief from vagus nerve stimulation; Blood sugar spikes after meals—even absent diabetes—can drive Alzheimer’s risk; New study pushes back on Tylenol-autism link, but highlights poor diet, chemical exposure , pre-natal anti-depressant use as potential culprits.
Registered dietitian nutritionist Leyla Muedin discusses a Nature Communications study of 108,723 French adults in the NutriNet-Santé cohort (2009–2023) examining long-term exposure to food preservatives and type 2 diabetes. Using detailed dietary records cross-referenced with product/additive databases, researchers identified 58 preservative-related additives and analyzed 17 consumed by at least 10% of participants; 1,131 diabetes cases occurred. Higher overall preservative intake was associated with a 47% increased diabetes risk (49% for non-antioxidant preservatives; 40% for antioxidant additives), with several specific additives linked to higher risk. Leyla questions whether the findings reflect preservatives themselves or the ultra-processed, refined-carbohydrate foods that contain them, emphasizing recommendations to favor fresh, minimally processed foods and limit refined carbs and processed foods.
Gary Taubes on Rethinking Diabetes: Diet, Insulin, and the History Behind Low-Carb Treatment: Journalist Gary Taubes is author of “Rethinking Diabetes: What Science Reveals About Diet, Insulin, and Successful Treatments.” The book traces diabetes treatment history and argues that carbohydrate restriction was standard care from 1797 through the early 20th century until insulin therapy shifted practice toward drug-centered management and higher-carbohydrate diets. Taubes explains how insulin’s discovery changed dietary priorities, how later technology (radioimmunoassay) revealed that most diabetes is type 2 with insulin resistance and high insulin rather than deficiency, and why giving more insulin can worsen weight gain. They discuss major trials (including ACCORD, ADVANCE, and Look AHEAD) that failed to show benefits from intensive drug-based glucose control, the influence of low-fat guidelines, Richard Bernstein’s role in blood-glucose self-monitoring and low-carb control, controversies about obesity models, ketosis vs ketoacidosis, GLP-1 drugs, and LDL increases on ketogenic diets.
Dr. Hoffman continues his conversation with journalist Gary Taubes, author of “Rethinking Diabetes: What Science Reveals About Diet, Insulin, and Successful Treatments.”
Urolithin A (MitoPure)--Mitophagy, Muscle Recovery, Immunity, and Skin Health: Dr. Brad Currier, clinical trial manager at Timeline, a Swiss biotech company, details urolithin A (MitoPure), a postbiotic derived from pomegranate precursors that most people cannot produce due to microbiome differences. Currier explains MitoPure’s mechanism—stimulating mitophagy to recycle dysfunctional mitochondria—and reviews evidence from multiple clinical trials. He reveals a Sports Medicine study in elite male distance runners showing reduced creatine kinase and lower perceived exertion, suggesting improved recovery, plus trials in middle-aged and older adults showing improvements in strength, six-minute walk test, and VO2 max at 500 mg–1 g doses. They also cover a Nature Aging immune study reporting rejuvenation of stem-like CD8 T cells with improved mitochondrial fatty acid oxidation, ongoing research directions, supplement quality/testing for athletes, and topical urolithin A skincare trials and partnerships, including L’Oréal Lancôme.
