👋 Welcome to Healthy, Again. I'm Max, and this publication is all about taking your health back: real food, straight talk, and time-tested wisdom, for you and your family.
01 The smoke is back, and it's more than a bad view
Canadian wildfire smoke poured over the US this week and shoved the air into "unhealthy" and worse. Chicago's air quality index blew past 700 on July 16, deep in "hazardous" territory, and Detroit, Minneapolis and New York briefly ranked among the most polluted major cities on earth. This is not just a hazy skyline. Long-term exposure to wildfire smoke's fine particles is tied to roughly 11,000 US deaths a year, most of them driven by the heart, not the lungs. If the air looks dirty, it is.
How to read the AQI in five seconds. The EPA scale runs 0 to 500. Green (0 to 50) is clear, yellow (51 to 100) is fine for most, orange (101 to 150) is the warning line for kids, older folks and anyone with heart or lung trouble, red (151 to 200) is bad for everyone, and purple or maroon (201 and up) means stay inside. On smoke days, run a HEPA filter indoors, keep the AC on recirculate, and wear a real N95 outside. A cloth mask does nothing against this.
02 A rough week in the food supply
The CDC is juggling several outbreaks at once, and a few deserve your attention. A parasite called cyclospora has sickened more than 1,644 people across five states, traced to shredded iceberg lettuce served at Taco Bell. Frozen GreenWise organic blueberries sold at Publix were recalled after an E. coli outbreak, so check your freezer for lot 60401. More sobering, four infants were hospitalized with botulism linked to recalled Nara Organics powdered formula, and a Listeria outbreak in soft "requeson" cheese has killed one person. The through line: fresh, organic and imported all still need a careful eye.
03 Testosterone goes to war
Testosterone is suddenly everywhere. Defense Secretary Pete Hegseth ordered annual testosterone screening for troops 30 and older, branding it the "High-T Department of War." It lands on top of a real trend: large studies show average male testosterone has been sliding for decades, with one NHANES analysis finding young men's levels dropped about 25% from 1999 to 2016 (how much is rising obesity versus something else is still debated).
We keep getting asked to dig into declining T.
✿ QUICK HITS — ON OUR RADAR
Your 3pm coffee is still working at bedtime. Even when caffeine doesn't stop you falling asleep, a review of 32 studies found it flattens deep, slow-wave sleep, and habitual drinkers aren't spared.
Medicare now covers weight-loss shots. A CMS pilot that went live July 1 covers GLP-1 drugs for weight loss for about $50 a month, and KFF estimates nearly four million people qualify. Check your Part D plan and ask about the prior authorization.
The vaccine mandate's long shadow. A new report tracks the fallout from the military's COVID vaccine mandate, where about 100,000 troops left and only a few hundred have been reinstated, as back-pay lawsuits stack up. Some cited health-harm figures come from a senator's reading of a Pentagon database the DoD disputes, so weigh those carefully.
✿ ONE GOOD THING
To end on a good one: Kasen Arnaud, 8, of Lake Charles, lost about four inches off one leg after an MRSA infection wrecked his growth plate as a baby. After leg-lengthening surgery this spring, and a neighborhood that rallied around him, he is out of the wheelchair and walking without his walker.
Next goal: baseball. As his grandfather put it, "it's really good to know that there's still good people."
