Recommended Daily Intake

There is no universally agreed-upon safe limit for diet drink consumption. However, several health organizations and research studies offer some guidance:

  • Mayo Clinic: Suggests that a “reasonable” amount, such as one or two cans a day, is unlikely to cause harm to most people.
  • American Heart Association: Advises against “regular and long-term consumption” of diet drinks, citing potential links to heart problems and stroke.
  • Observational studies: Some studies have associated high diet drink intake (two or more per day) with an increased risk of heart disease, stroke, and type 2 diabetes. However, more research is needed to establish a causal relationship.

Factors Affecting Individual Tolerance
