Since the term “antioxidants” made the leap from the realm of biochemistry labs and into the public consciousness in the 1990s, Americans have come to believe that more is better when it comes to consuming the substance that comes in things like acai berries, green tea and leafy veggies.
A provocative new study published Wednesday in the journal Nature raises important questions about that assumption.
This article leaves off a couple of important points on the research
- Anti-oxidants increase the rate at which metastases form, and do not appreciably affect the growth of the primary tumor.
- The study focused on melanoma xenografts only, some of which are highly metastatic. This will probably apply to other kinds of cancer as well, but that needs to be more fully investigated.
- N-acetylcysteine isn’t just an antioxidant.
Here’s the journal article itself (behind a paywall).
