I'm a Dietitian, and This Is What I Tell People Who Drink Diet Soda Every Day
Key Points:
- Diet soda contains non-nutritive sweeteners like aspartame, sucralose, and acesulfame potassium, which are FDA-approved and considered safe within acceptable daily intake limits for most people.
- Research shows that replacing sugary drinks with diet soda can lead to modest weight and fat reductions, but long-term effects on heart health are unclear due to conflicting evidence and potential confounding factors.
- Some studies suggest artificial sweeteners may impact gut microbiome and blood sugar regulation, but these effects vary among individuals and require further research.
- Compared to regular soda, diet soda is generally a better choice for reducing sugar intake, but unsweetened beverages like water remain the healthiest option for hydration.
- People who consume large amounts of diet soda, have certain health conditions like phenylketonuria (PKU), or experience negative effects such as dental sensitivity or disrupted sleep should consider limiting their intake.
