What's new in feeling better and living longer. 5-minute read.
Good morning. Today: a new estimate of alcohol's lifetime toll, what nearly 6 million 23andMe health reports turned up, and a big shift in how low-risk prostate cancer is handled.

01 ยท ALCOHOL
Two drinks a day was tied to a 1-in-25 lifetime risk of alcohol death
A new analysis estimated that Americans averaging 14 drinks a week face about a 1 in 25 lifetime risk of dying from an alcohol-related cause.
Why it matters: About two drinks a day is a common habit, and the study was originally commissioned by the U.S. government to inform dietary guidance.
The details: Researchers reviewed more than 7,200 publications on alcohol-related illnesses and injuries and combined those risks with national health data. Up to 7 drinks a week was linked to only small risk increases for most conditions. The paper ran in the Journal of Studies on Alcohol and Drugs.
Yes, but: These are modeled, population-level estimates, not individual predictions. Low intake may be tied to less ischemic heart disease and stroke, but once cancer and other outcomes were counted, the team said it "did not observe a significant protective effect of alcohol on health at any level of consumption."
02 ยท AT-HOME TESTING
About 1 in 10 23andMe users got a medically actionable result
Of nearly 6 million U.S. research participants who got 23andMe's FDA-authorized health risk reports from 2017 to 2025, more than 635,000 (10.6%) had at least one result tied to a condition with screening or prevention options.
Why it matters: At-home DNA kits can flag inherited risks for cancer, heart disease and blood clots that people may not know they carry.
The details: The reports cover 91 variants in 20 genes. Results included nearly 11,800 in BRCA1, BRCA2 and MUTYH (hereditary cancer), more than 21,000 in genes tied to cardiovascular disease and more than 430,000 tied to inherited clotting disorders. Given the choice, 93.8% of participants opted to see their reports.
Yes, but: These are early findings presented at the American Society of Human Genetics meeting and shared in a press release from 23andMe's nonprofit research institute; it isn't clear they've been peer reviewed.
03 ยท PROSTATE HEALTH
Most low-risk prostate cancer is now watched instead of treated
In national registry data, the share of men with low-risk prostate cancer who got neither radiation nor prostate removal rose from 33.6% to 83.4% between 2010 and 2023.
Why it matters: What happens after an abnormal PSA test is one of the most common health decisions men face, and practice has changed a lot.
The details: University of Michigan researchers analyzed the SEER cancer registry, Veterans Affairs records and a Michigan radiation oncology group, publishing in the journal Cancer. In the VA, the untreated share went from 51.6% to 96.3%. Low-risk cases also became a smaller share of new diagnoses, which lead author Dr. Steven Monda said likely reflects more MRI use in screening.
Yes, but: The three datasets cover different groups and time spans, and the summary didn't report full study size or funding. Talk to your doctor about what fits your situation.

Quick Hits
Tea and blood vessels. In nearly 486,000 adults from the China Kadoorie Biobank followed about nine years, regular tea drinkers had an 11% lower relative risk of vascular disease, lowest around 6 to 8 cups a day; it's observational, and experts cautioned against treating that as a target.

Aspirin, dementia and genes. In a genetic re-analysis of the ASPREE trial, people with the highest platelet-count genetic scores had dementia rates of 1% on low-dose aspirin vs. 3.3% on placebo, but major bleeding was 4.4% vs. 2.1%; the lead author said not to start aspirin for this without talking to a doctor.

Sleep gummies, in mice. Mice given cannabinol (CBN), a cannabinoid sold in sleep gummies, twice a day for three days became less responsive to it and showed withdrawal signs, a UConn study found; it wasn't tested in people. ScienceDaily
Drinks and mouth bacteria. In a not-yet-peer-reviewed study of 5,598 U.S. adults, higher alcohol intake was linked to more of some bacteria previously tied to poor oral health, with liquor showing the biggest jump in bacterial variety; it can't show cause and effect. News-Medical
