Due to the great popularity of “Can Diet Coke Kill You?” combined with a lot of controversy over it, I have decided to write this follow-up post.
Most of the controversy over the last article was around the fact that the documentary I referenced cited data from the National Cancer Institute (NCI) but that organization itself claims there is no proven link between aspartame and cancer.
What was presented previously was a short explanation of why aspartame is expected to cause cancer and other health problems and a summary of some information presented in Sweet Misery, including findings from analyzing NCI and other data. This article, however, cites other scientific findings and discusses the economic-political history of this topic a little bit as well.
As if it wasn’t bad enough that particulate matter from diesel exhaust causes a range of respiratory problems including 15,000 premature deaths each year, new research shows that even short-term exposure to nanoparticles found in diesel fumes can affect brain function.
Nanoparticles can travel to the brain via the olfactory nerve, where they could cause an oxidative stress response in the region of the brain critical to information processing.
Researchers placed subjects in a room with either clean air or diesel fumes (similar to a busy street), and used a electro- encephalograph (EEG) to measure brain response. Subjects breathing the sooty air showed a stress response in the brain’s cortex within 30 minutes, which continued even after they left the room.

When I was in 7th grade, someone gave me a “word-a-day” vocabulary building calendar. Nothing made me happier than showing off with words like “incongruous.” What would have made it more fun, however, would’ve been doing good while expanding my word use!
The UN World Food Program has come up with an ingenious game, Free Rice. You are presented with four or five definitions for a word and with each correct answer, 20 grains of rice are donated to feed the hungry around the world.
It didn’t take me long to work up to 1080 grains of rice and I had the option to set the game to remember my computer and add to the total.
