Can Your Apple Watch Tell How Old Your Body Is?

Your Apple Watch can tell you something real about aging-related health, just not as a single age. The measures Apple feeds into its new Health Age score are among the better-studied things you can track on your own: fitness, resting heart rate, sleep, HRV, and optional labs. Several are tied to future health outcomes, and several can be improved. The score built on top of them is another matter. As of September 10, 2026, no peer-reviewed study was found showing Apple's Health Age predicts disease or death, so watch the ingredients, not the verdict.

New Breast Cancer Pill Triggered by a Blood Test: Who Qualifies?

If you're on a first-line aromatase inhibitor plus a CDK4/6 inhibitor for HR-positive, HER2-negative metastatic breast cancer, there's a new option worth understanding. On September 4, 2026, the FDA approved camizestrant (Etcamah) as the first cancer therapy triggered by a blood test rather than a growing tumor on a scan. In the trial that won it approval, switching the moment an ESR1 mutation appeared in the blood roughly doubled the time before the cancer advanced. Whether it also extends life is what the next few years of follow-up will answer.

What Does the New FDA-Approved Alexander Disease Drug Do?

On September 3, 2026, the FDA approved Zanvastro (zilganersen), the first drug shown in a controlled trial to slow Alexander disease itself rather than manage its symptoms. In the pivotal 54-patient study, quarterly spinal injections kept treated patients walking measurably better than untreated ones at about a year. It isn't a cure, and the delivery is a lumbar puncture every 12 weeks for life. But for families who until now had only supportive care, the ceiling on this disease has moved for the first time in decades.

Are Broccoli Sprouts Safe to Eat Raw After the Evergreen Outbreak?

Broccoli sprouts are still worth eating, and the sulforaphane research holds up. The catch right now is one brand: sixteen people across Washington, Montana, and Idaho have Salmonella tied to Evergreen Fresh Sprouts broccoli sprouts. Toss any Evergreen sprouts in the fridge and clean what they touched. Sprouts are the rare vegetable where washing cannot undo contamination once a seed carried it in. If you want to keep eating them, cook them.

Are Your Publix or Walmart Frozen Blueberries Recalled?

If you have organic frozen blueberries or mixed berries from Publix or Walmart in your freezer, check the bag. The FDA has escalated the recall to Class I, its most serious tier, after people across Florida and Georgia got sick from Shiga toxin-producing E. coli O145:H28 traced to a single Chilean supplier. Freezing doesn't kill this bug, and rinsing won't reliably wash it off. If your bag matches, throw it out.

What's the Difference Between 2D and 3D Mammograms?

A 3D mammogram is still a mammogram, but it takes X-ray images from several angles and rebuilds the breast into thin slices, so overlapping tissue is less likely to hide a cancer or mimic one. In practice it usually finds a little more cancer, especially invasive tumors, and in U.S. clinics it often means fewer callbacks for a second look. What it hasn't yet clearly proven is that catching those extra cancers leads to fewer interval cancers, advanced cancers, or breast cancer deaths for most women. If 3D is available and covered, it's a reasonable choice; if only 2D is available or affordable, the mammogram you actually get on schedule matters far more than which machine takes it.

Does the MMR Shot Still Protect My Child as Measles Spreads?

Two MMR doses on the standard schedule give your child roughly 97% lifetime protection against measles, and that number has held up in huge cohorts followed more than a decade out. Whether the US formally loses its elimination certificate in November matters far less to your family than whether the kids in your child's daycare, classroom, and pediatric waiting room are vaccinated. The gap is uptake, and it's fixable this week.

Upper East Side Legionnaires' Killed 11: Is It Safe Now?

For most people who spent time on the Upper East Side this summer, the danger has passed. The last case was diagnosed July 21, and every cooling tower that grew live Legionella has been cleaned. What still matters is the two weeks after any exposure. If you develop fever, cough, muscle aches, diarrhea, or confusion within 14 days of being in Carnegie Hill or Yorkville (ZIPs 10028, 10075, 10128), ask specifically for a Legionella urinary antigen test plus PCR or sputum culture, and push for antibiotics fast.

Who Should Get COVID, Flu, and RSV Shots This Fall?

This fall, the major U.S. doctors' groups recommend the updated COVID, flu, and RSV shots for a wider group than the FDA label and CDC now cover. AAFP endorses the updated COVID shot for every adult 19 and up. ACOG urges COVID, flu, and RSV vaccination in every pregnancy. AAP kept routine COVID vaccination for babies 6 to 23 months and high-risk kids 2 to 18. If your own physician recommends a shot the FDA label no longer lists you on, the evidence is behind them.

Can a Pill Replace CPAP for Sleep Apnea?

For an adult who can't live with a CPAP mask, the answer is starting to be yes. AD109, a once-nightly pill, is the first drug in decades of trying that credibly opens the sleeping airway. In Phase 3 trials it cut breathing interruptions by roughly 44 to 47 percent from baseline versus about 7 to 18 percent on placebo, and the FDA is set to decide on approval by February 28, 2027. It has real side effects, and no trial has yet shown it lowers heart attacks or strokes, so it's a partial fix aimed at people the mask has failed, not a replacement for a CPAP that's working.

Does obesity leave a 'memory' in your body after weight loss?

Yes, obesity leaves a fingerprint on your immune cells that can outlast the scale by years. A new University of Birmingham study finds a DNA methylation pattern on CD4+ T cells that the authors estimate takes roughly five to ten years of sustained lower weight to fade. The hopeful part: losing weight starts reversing that imprint on day one, and keeping it off is what finishes the job.

Is Lipofit Safe? FDA Found Prozac and a Banned Toxin Inside?

If you have a bottle of Lipofit Extreme Fat Burner 2.0 (lot 25M12F, expiration 09/2027), stop taking it and use the recall line to return it. FDA lab testing found the daytime tablets spiked with Prozac and the nighttime tablets spiked with 2,4-dinitrophenol, an industrial pesticide long banned for human use. If you've felt unusually hot, sweaty, or noticed a racing heart in the past few days, go to an emergency room and say you may have taken 2,4-dinitrophenol.

Are ZYN Ultra Nicotine Pouches Actually FDA-Approved as Safe?

An FDA marketing order isn't a stamp of safety. It's a bet that the strongest ZYN yet will do more good for adult smokers who switch than harm to new users it pulls in. That's why the agency cleared 11 ZYN Ultra pouches on August 21, 2026, and also why it refused to let them carry the lower-risk-than-cigarettes claim it gave 3 mg and 6 mg ZYN two months earlier. If you already smoke and can trade cigarettes fully for pouches, the deal favors you. If you don't use nicotine, Ultra is the wrong product to start on.

What's a Healthy Waist Size for Men and Women?

A cloth tape around your middle tells you something a scale can't: whether you're carrying the deep belly fat that drives heart disease and diabetes risk. For most adults, the target is a waist under half your height. That rule is now backed by a 2026 JAMA Network Open analysis and the UK's 2025 NICE guideline, and the tape is the cheapest useful home health number after a blood pressure cuff.

Can Omega-3 and Aspirin Replace Antibiotics for Gum Disease?

For severe gum disease, yes, for many people. Daily omega-3 with low-dose aspirin, added to a deep cleaning, hit the treatment goal in about the same share of patients as the standard antibiotic combo, and both roughly doubled the result of cleaning alone. Combining them added nothing. Aspirin's bleeding risk means this trade isn't for everyone, but it's a live option worth raising with your periodontist before you accept a two-week course of amoxicillin and metronidazole.

Does a Blood Pressure Under 130 Lower Dementia Risk?

If your systolic runs 140 or higher, getting it under 130 now has randomized evidence for your brain, not only your heart. Intensive blood pressure control lowered new dementia cases by about 15% over seven years, and did it with fewer serious adverse events in the treated group than in usual care. That closes a gap the field has been carrying since SPRINT MIND.

Why Do My UTIs Keep Coming Back After Antibiotics?

Antibiotics keep failing because in many women the recurring problem is no longer a simple infection. A 2026 chart review of 253 women referred to a specialty clinic for persistent urogenital symptoms found only about 15% had a classic urologic cause. The rest had hormonal changes at the vaginal opening and pelvic floor, or bacteria embedded where standard urine cultures don't see them. What breaks the cycle is treating that driver: vaginal estrogen after menopause, a pelvic floor and vulvovaginal evaluation when cultures keep coming back negative, and a workup that reaches past another prescription.

Is Mounjaro now an FDA-approved heart medicine?

Yes. On August 28, 2026, the FDA approved Mounjaro (tirzepatide) to lower the risk of heart attack, stroke, and cardiovascular death in adults with type 2 diabetes and established atherosclerotic cardiovascular disease. It joins semaglutide, liraglutide, and dulaglutide as a heart-protection option in this group. What tipped the approval wasn't a lower heart-attack rate. It was fewer deaths.

Should You Take Statins After 70?

If you're 70 or older, a statin is worth considering when your chance of a first major cardiovascular event is high enough to make daily medication worth it. The new STAREE atorvastatin trial strengthens that case, but it doesn't turn age itself into a reason to start. It found fewer events in a broad endpoint that included cardiovascular death, nonfatal heart attack, stroke, and coronary revascularization. The reduction was driven mainly by fewer heart attacks and coronary procedures. It did not extend disability-free survival. So the useful question is personal: how much event risk are you trying to prevent?

Can a Weekly Shot Replace Blood Draws for Polycythemia Vera?

Yes, for most adults with polycythemia vera who depend on regular phlebotomies, a newly approved once-weekly shot can replace them. The FDA cleared Mimrylo (rusfertide) on August 28, 2026. It's an add-on to standard care, not a cure, and hasn't yet been shown to prevent clots or extend life.
