That's a ridiculous analogy. What about suger-free sodas, or sparkling water without even artificial sweeteners? What about people who drink soda, but still don't go over the daily recommended sugar intake, and otherwise have healthy lifestyles?

I'd be willing to make two assumptions:

1. A gaping wound in your leg is probably less healthy than a moderately-high sugar consumption.

2. People who are concerned about nanoplastic intake are probably also concerned about deleterious health effects of things like sugar intake.
