Industry-funded study of this week: Maple water!

Hat tip to Matthew Kadey for this one.  It’s a great example of a study title that makes me want to know : Who paid for this?

  • The study: Randy L. Aldret, Michael McDermott, Stephanie Aldret, Greggory Davis and David Bellar. The Acute Effects of a Maple Water Drink on Exercise Responses, Oxidative Stress and Inflammation in Overweight College Males. Journal of Food and Nutrition Research. 2022; 10(9):593-599. doi: 10.12691/jfnr-10-9-2
  • Rationale: “The purpose of this study was to examine the acute effect of maple water on exercise responses and biomarkers of post-exercise inflammation and muscle damage in an overweight male college population.”
  • Method: “The treatments for the study consisted of 12 fluid ounces (355ml) of pure MW (Drink Simple Maple Water, Drink Maple LLC) or an identical volume of distilled water flavored with maple extract to mimic the smell and taste.”
  • Conclusion: “Early outcomes indicate maple water has positive benefits for those that exercise in the areas of cardiovascular fitness and post exercise inflammation.”
  • Competing Interests: “The authors declare the following real or perceived conflicts of interest in the context of this study: financial conflict of interest, as this study was funded in part by grants from Drink Simple LLC (Grant #370261).”
  • Comment:  The comparison here is maple water versus plain water.  Maple water contains sugars and electrolytes (potassium, manganese, calcium); the water placebo does not.  The result seems predictable from the funder, as is the study design.
