Tattoos may increase the risk of lymphoma. Electrolyzed-reduced water supports longevity. Urolithin A, found in pomegranate, strawberries, and walnuts, improves memory function. Fish oil supplements may have adverse effects. Match mouthwash fights bad oral bacteria.

Every week we discover inspiring, informative, and sometimes shocking health-related news. From new studies to insightful analysis, here is what you need to know this week:

  • Tattoos may increase the likelihood of developing lymphoma. New research from Sweden evaluated those who developed the cancer and determined “that the risk of developing lymphoma was 21% higher among those who were tattooed.” eClinicalMedicine
  • Electrolyzed-reduced water may support longevity and fight age-related diseases. A new study indicates that electrolyzed-reduced water, also known as alkaline ionized water, has powerful antioxidant properties that support normal cells and weaken cancer cells. Aging
  • Urolithin A, a naturally occurring substance found in pomegranate, strawberries, and walnuts, can improve memory and support the treatment of Alzheimer’s disease. Recent research from Denmark demonstrates that urolithin A can “alleviate memory problems and other consequences of dementia.” Alzheimer’s & Dementia
  • Fish oil supplements may have adverse effects. A large analysis from the United Kingdom’s Biobank indicates that fish oil supplementation may increase the risk of first-time cardiovascular events but decrease the risk for those already suffering from cardiovascular disease. The mixed results indicate the need for further research. BMJ Medicine
  • Matcha mouthwash inhibits the growth of bacteria that causes periodontitis and other oral health problems. New research from Japan indicates that matcha, a prepared green tea powder, reduced the amount of P. gingivalis bacteria in people that used match mouthwash. Microbiology Spectrum
