Diet Pop is healthier than Regular Pop

One can of regular pop contains about 135 kilocalories whereas a can of diet pop contains less than 10 kilocalories; some even contain zero kilocalories. Therefore, it is true that diet pop contains fewer calories. However, it is rather difficult to agree that diet pop is "healthier" as there is really nothing healthy about artificially colored and flavored water.
