A new randomised clinical trial, published in the journal
JAMA Network Open, has found regularly donating blood or plasma can reduce blood PFAS levels.
PFAs are often referred to as "forever chemicals" because they do not break down easily in the environment and can accumulate over time in the human body and wildlife. Concerns have been raised about their potential health effects, including links to cancer, liver damage, immune system effects, and developmental issues. As a result, there is increasing regulatory scrutiny and efforts to limit their use and exposure.
Blood viscosity aside, donate 2-3x per year.
