Japanese study finds pterostilbene in blueberries may boost fat breakdown in muscle cells

Laboratory research suggests a natural compound could help address obesity and metabolic decline, but human trials are needed.

What to know

  • Japanese researchers found pterostilbene, a compound in blueberries and grapes, reduced fat accumulation in cultured mouse muscle cells by increasing fatty acid breakdown.
  • The compound appeared to preserve PPAR-delta protein, which regulates how cells process fat, offering a potential mechanism for metabolic benefits.
  • Experts emphasize that lab results with cultured cells do not confirm the effect will translate to humans; digestion, absorption, and dosage all matter in living organisms.
  • Future studies in humans and animals are needed before pterostilbene can be considered a viable dietary approach to obesity or type 2 diabetes.

“We also can't assume mouse muscle cells will respond exactly like human muscle.”

    Fox News covers blueberry compound research, notes human studies still needed

    Fox News reports on the Food Bioscience study and includes expert analysis from registered dietitian Johannah Katz cautioning that lab results with cultured cells do not necessarily predict human outcomes, since pterostilbene must first be digested, absorbed, and reach muscle tissue at an effective dose.

    “In people, pterostilbene has to be digested, absorbed, metabolized, circulated and actually reach muscle tissue at an effective dose.”

    Japanese researchers publish pterostilbene study in Food Bioscience — A team at Shinshu University led by Takakazu Mitani found that pterostilbene, a natural polyphenol in blueberries and grapes, reduced fat accumulation in cultured mouse skeletal muscle cells by encouraging them to break down stored fat while preserving muscle growth.
