Light produced by CFLs is "cooler" - tinged a light blue or green - than the yellowish glow of an incandescent, and many people complain that the effect is less aesthetically pleasing. CFLs raise concerns because there is a danger of mercury exposure if the bulbs break, which makes disposal tricky. And some people allege that long-term use of fluorescent light causes health problems, though experts are largely skeptical of the claim...

In 1995 and 1996, misinformation about aspartame that linked the chemical to everything from multiple sclerosis to Gulf War syndrome was widely disseminated on the Internet. While aspartame does adversely effect some people - including those who are unable to metabolize the amino acid phenylalanine - it has been tested more than 200 times, and each test has confirmed that your Diet Coke is safe to drink. Nor have any health risks been detected in more than 100 clinical tests of sucralose...
