Splenda was discovered by accident! Is it really zero calories, though?

Sucralose, more commonly known as the artificial sweetener Splenda, was discovered in 1976. Two scientists named Leslie Hough and Shashikant Phadnis were researching ways to use sucrose. During one experiment, Phadnis was told to test a chlorinated sugar compound. However, Phadnis misheard and thought Hough asked him to TASTE it!

Nowadays, Splenda is one of the most popular sugar substitutes. Sucralose is most commonly found in diet sodas and sugar-free gum. It's also been found safe for diabetics to consume, since it doesn't affect insulin levels.

Don't believe the zero-calorie claim that Splenda boasts, though. Each packet contains about 4 calories due to the fillers that allow it an extended shelf life!
