Compound in common fruits may improve muscle fat metabolism, study finds
Fox News • • general
Key Points:
- Researchers in Japan found that pterostilbene, a natural antioxidant in blueberries and grapes, reduces fat accumulation in cultured mouse muscle cells by promoting the breakdown of stored fat.
- The compound appears to preserve the protein PPAR-delta, which regulates fat metabolism in muscle cells, potentially preventing abnormal fat buildup linked to insulin resistance.
- The study, published in Food Bioscience, suggests pterostilbene could inform the development of functional foods and supplements targeting muscle fat metabolism.
- Experts caution that these findings are preliminary and based on lab-grown mouse cells, emphasizing the need for human and animal studies to confirm if pterostilbene has similar effects in people.
- Nutritionists note that while blueberries and grapes are healthy, this research does not prove that consuming them or pterostilbene supplements will directly reduce muscle fat in humans.
