In new research published online in The FASEB Journal, scientists show that the antioxidant pyrroloquinoline quinone (PQQ) may prevent the development of nonalcoholic fatty liver disease in offspring. The research, which used mice, is the first to demonstrate that PQQ has this type of protective effect. PQQ is a naturally occurring antioxidant found in soil and foods, such as soy, parsley, celery, kiwi, and papaya, and is also present in high quantities in human breast milk.
