People argue constantly about how dangerous diet soda is. The main arguments include:
- Aspartame is bad
- Man-made sweeteners are bad
- You shouldn’t drink anything that ants walk around
- Fake sugar tricks the body into thinking it’s real sugar
All good points, but I think I can simplify.
None is best
If you are the type of person who can switch completely off of soda and only drink water, tea, coffee, and other more healthy beverages, then you absolutely should. There’s no question that diet soda is worse for you than water and tea and coffee.
Light should be regular
If you are someone who only has the occasional soda—say, once a month—you should probably drink regular soda. The aspartame and other weirdness in diet soda is more likely to bother you at extremely low frequencies (headaches, stomach aches, etc.).
But if you’re the type of person who is going to drink soda in any significant volume, switching from regular soda to diet is probably a really good idea. Ingesting large quantities of liquid sugar is simply known to be horrible for you. The calories leading to obesity is one angle, and the increased chance of diabetes due to constantly spiking your insulin is another.
- Don’t drink soda if you can avoid it
- If you only have one occasionally, drink a regular one
- And if you drink a lot, switch to diet
