Eat Fermented Food Today — Sep 11, 2026

Fri, 11 Sep 2026 06:30:00 -0700

Today, eat fermented food — yogurt, kefir, kimchi, sauerkraut, fermented cottage cheese, or kombucha. Build toward multiple servings across the day, the way the trial ramped intake. Educational tip only. Not medical advice. Wastyk HC et al., Cell 2021;184(16):4137-4153.e14. Randomized prospective study, n≈18 per arm (high-fermented vs high-fiber), 17 weeks. Fermented-food diet increased microbiota diversity; 19 of 93 inflammatory serum proteins decreased (incl. IL-6); less activation in four major immune cell types. Primary cytokine response score unchanged. High-fiber: stable diversity; increased CAZymes; personalized immune trajectories. DOI 10.1016/j.cell.2021.06.019 PMID 34256014. Small healthy-adult trial, not an autoimmune or metabolic disease outcomes study. Primary cytokine response score unchanged. Fiber still remodeled microbiome function with personalized immune trajectories. Fermented food is not a cure for arthritis, diabetes, or aging. Dairy-free or histamine-sensitive: pick options you tolerate, or ask your clinician. Educational tip only. Not medical advice.

Take Creatine Monohydrate Today — Sep 10, 2026

Thu, 10 Sep 2026 06:30:00 -0700

Today, take creatine monohydrate — a common evidence dose is about 3 to 5 grams daily mixed in water or a shake (trial doses in the meta ranged roughly 2.2–20 g/day). Stay hydrated. If you have kidney disease, are pregnant, or your clinician said no to creatine, skip or ask first. Educational tip only. Not medical advice. Prokopidis et al., Nutrition Reviews 2023;81(4):416-427. Systematic review + meta-analysis of RCTs. 10 RCTs in review; 8 in meta-analysis. Overall memory vs placebo SMD 0.29 (95% CI 0.04–0.53; I²=66%; P=0.02). Older adults 66–76: SMD 0.88 (95% CI 0.22–1.55; I²=83%; P=0.009). Younger 11–31: SMD 0.03 (95% CI −0.14 to 0.20; I²=0%; P=0.72). Dose ≈2.2–20 g/d; duration 5 days to 24 weeks. DOI 10.1093/nutrit/nuac064 PMID 35984306. Meta of small RCTs with heterogeneity. A published letter raised possible double-counting concerns — treat effect sizes as provisional. Not an outcomes trial for dementia, Alzheimer's, stroke, or lifespan. Memory tests are not a diagnosis. Clearest pooled signal in older adults. Kidney disease, pregnancy, or clinician caution: skip or ask first. Stay hydrated. Educational tip only. Not medical advice.

Do 30 Resistance Breaths Today — Sep 9, 2026

Wed, 09 Sep 2026 06:30:00 -0700

Today, do 30 slow, forceful inhalations through a high-resistance IMST device, about 5 minutes (trial used about 75% maximal inspiratory pressure, 6 days/week). If no device yet, order a clinician-appropriate IMST trainer and start when it arrives. Do not improvise unsafe homemade resistance. Not a substitute for prescribed BP care. Educational tip only. Not medical advice. Craighead et al., Journal of the American Heart Association 2021;10(13):e020980. Double-blind RCT, adults 50 to 79 with SBP 120 or higher. n=36 completers. High-resistance IMST 75% vs sham 15%. 30 breaths/day, 6 days/week, 6 weeks. Adherence about 95%. Casual SBP 135±2 to 126±3 with IMST (P<0.01); about 75% of the benefit still present at 6 weeks after stopping. DBP 79±2 to 77±2 (P=0.03). Sham unchanged. 24-hour SBP lower after IMST vs sham (P=0.01). FMD improved about 45% with IMST. DOI 10.1161/JAHA.121.020980 PMID 34184544. Small n=36. Above-normal SBP, not severe uncontrolled hypertension, pregnancy, or acute cardiopulmonary disease. Benefits after 6 weeks of near-daily training, not one Wednesday session. Not an outcomes trial for MI, stroke, or death. Do not stop or change BP meds from a reel. Device resistance matters. Dizziness, ear or pressure issues, recent surgery, or a clinician who said no to resisted breathing: skip or ask first. Educational tip only. Not medical advice.

Try the free SAGE test today — Sep 8, 2026

Tue, 08 Sep 2026 05:00:00 -0700

Print or download the free Self-Administered Gerocognitive Examination (SAGE) from Ohio State (sagetest.osu.edu), take it yourself in a quiet spot with a pen, about 10 to 15 minutes, no timer pressure, then bring the scored page to your clinician. Screen for early thinking and memory change, not a diagnosis. Educational tip only. Not medical advice. The lie I taught in medical school: if you still drive, pay bills, and chat at dinner, cognition is fine. Everyday function can look intact while early MCI is already measurable on a multidomain screen. Scharre et al., Alzheimer Disease and Associated Disorders 2010;24(1):64-71. Adults over 59. 254 took SAGE; 63 full workup (21 normal, 21 MCI, 21 dementia). Spearman SAGE vs neuropsych 0.84 (MMSE 0.76). ROC: SAGE specificity 95%, sensitivity 79% for cognitive impairment vs normal (MMSE 90%/71%). DOI 10.1097/wad.0b013e3181b03277 PMID 20220323. Validation subset n=63. Not an RCT proving home SAGE extends life or prevents dementia. Screen is not a diagnosis. Low scores need clinician follow-up. High scores do not rule out every cause. English literacy and adequate vision in this study. Education, culture, hearing, depression, sleep, meds, and acute illness affect scores. Educational tip only. Not medical advice.

Book a CAC Scan Today — Sep 7, 2026

Mon, 07 Sep 2026 07:00:00 -0700

If about 40+ (or younger with strong family history or metabolic risk), book a coronary artery calcium (CAC) CT. Cash-pay, usually a few hundred dollars, about five minutes, no needles, no treadmill. You leave with a score that shows whether calcified plaque is already in the coronary arteries. Bring the number to your clinician. Detrano et al., N Engl J Med 2008;358:1336-1345. MESA n=6,722. Versus CAC 0: adjusted risk ×7.73 (101–300) and ×9.67 (>300). PMID 18367736. Observational cohort prediction — not an RCT. Soft plaque without calcium can still exist. Score 0 is not a forever passport. Educational tip only. Not medical advice.
