New York Post Highlights Study Comparing Diet Soda to Water

The New York Post published a report this week comparing diet soda and water, under the headline "Unexpected truth about diet soda vs. water revealed in new study". The full methodology, sample size and lead researchers behind the study were not specified in the material reviewed by this desk, so the findings described below should be read as a developing story rather than a settled result.

What did the New York Post report?

The Post's headline frames the comparison between diet soda and water as producing a result the outlet characterizes as unexpected. The article ties that framing to a study that pit the two beverages against each other on at least one health measure, according to the outlet. Because the underlying study's name, publishing journal and date were not included in the source material available here, this report does not repeat specific figures or conclusions that cannot be verified against the original paper. Readers who want the full breakdown of what researchers measured should consult the Post's report directly.

Why do diet soda and water keep getting compared in research?

Diet soda and water sit at opposite ends of a familiar question for nutrition researchers and dietitians: whether a zero- or low-calorie sweetened beverage behaves the same way in the body as water when it comes to things like hydration, appetite and daily fluid intake. That question has produced competing findings over the years, with some studies describing diet soda as a reasonable substitute for sugared drinks and others raising questions about how artificial sweeteners interact with metabolism. The Post's new report adds to that ongoing debate, though without the specific data points that would let this desk state a number or statistic with confidence.

What isn't clear yet from this report?

Several basic facts are missing from the material available: the name of the study, the journal or preprint server where it appeared, the number of participants, and whether the research was observational or a controlled trial. Each of those details matters for how much weight a reader should put on the headline claim. A small observational study carries different implications than a large randomized trial, and the Post's report as summarized does not specify which applies here. Until the primary study is identified and reviewed in full, specific numeric claims about diet soda's effects relative to water should be treated as provisional.

How does this connect to broader eating habits coverage?

Questions about diet soda consumption often surface alongside broader conversations about processed food intake and the sweeteners used to replace sugar. Wynter's Wellness has previously examined how processed foods drive cravings and habitual consumption, a topic adjacent to debates over whether diet beverages help or hinder efforts to cut back on processed ingredients. That earlier reporting does not address the specific study cited by the Post, but it offers useful background on why beverage choices get scrutinized in the first place.

What should readers watch for next?

• Whether the original study is published in a peer-reviewed journal, which would allow independent verification of its methods and sample size.
• Whether other outlets or nutrition organizations respond to the Post's framing with their own review of the data.
• Whether follow-up coverage specifies calorie counts, participant numbers or other figures currently absent from this report.
• Whether federal health agencies, which regulate approved sweeteners, issue any comment tied to the study's claims.

Where can readers find the full study details?

The most direct path to the underlying research is the Post's own article, linked above, which should contain citation details or a link to the study itself. This desk will revisit the topic with sourced figures once the original paper or a fuller account of its methodology becomes available. In the meantime, readers deciding between diet soda and water for daily hydration should treat the "unexpected truth" framing as a headline claim awaiting fuller documentation rather than a confirmed finding.
