Issue by Issue Revisions, Part II: Obesity, Mercury

Today I'm working on updates to Chapter 9 of my book, which is divided up into sections about misuses of science to favor food industry interests and misuses of science to deny the dangers of mercury pollution and contamination of fish. The chapter itself is entitled "Eating Away at Science." However, it has been a very difficult one to update: There don't seem to have been many major developments in either of these stories in the past year or year and a half. Or am I missing something? Your thoughts appreciated.
