Researchers from Japan have found that pterostilbene, a compound in blueberries and grapes, can help muscle cells reduce fat accumulation. This research indicates that pterostilbene promotes the breakdown of stored fat in cultured mouse muscle cells. The findings, published in the journal Food Bioscience, highlight pterostilbene’s role as an antioxidant and its potential for developing functional foods and supplements targeting muscle fat metabolism.
The study outlines that excessive fat in muscle cells can hinder glucose and fatty acid usage, leading to insulin resistance. The lead researcher, Takakazu Mitani from Shinshu University, pointed out that the compound preserves a protein called PPAR-delta, crucial for fat processing.
While promising, experts like registered dietitian Johannah Katz urge caution, emphasizing that results from lab-grown cells may not directly apply to humans. Future research is needed to evaluate if these findings can translate into dietary applications addressing obesity and metabolic disorders.
