Smoking is one of the clearest lifestyle drivers of chronic inflammation and it shows up in the data. In a study of over 3,200 adults, daily smokers had the highest suPAR levels, while people who’d quit looked statistically no different from those who’d never smoked.
The takeaway: quitting is associated with a measurable drop in suPAR over time. Your body keeps the receipts, but it can also let them go.
