How do you verify that a soft-drink contains diet soda rather than sweetened with fructose?

You can't definitively verify if a soft drink contains diet soda or fructose just by tasting or looking at it. Here's why:

* Taste: Some diet sodas are very good at mimicking the taste of regular soda. While some artificial sweeteners have a slightly different aftertaste, it's not foolproof.

* Appearance: There's no visible difference between diet and regular soda. Both can appear clear and bubbly.

How to verify:

1. Check the label: This is the most reliable way. Read the ingredient list carefully. Look for:

* Artificial sweeteners: Aspartame, sucralose, saccharin, stevia, etc.

* Sugar: If the ingredients include sugar (sucrose or fructose), it's not a diet soda.

2. Nutritional information: Look for "zero calories" or "low calories" on the nutrition label.

3. Consult the manufacturer: If you're unsure, you can always contact the manufacturer directly for clarification.

Important note: If you are concerned about fructose consumption, it's best to choose diet sodas or drinks that are sweetened with artificial sweeteners.
