Compound in blueberries may help muscle cells burn excess fat
Researchers have discovered that pterostilbene, a compound found in blueberries and grapes, can help muscle cells burn excess fat by stabilizing the PPAR pathway. This finding offers a potential dietary approach to managing myosteatosis and improving metabolic health in aging populations.
Why it matters
It provides a potential non-pharmaceutical intervention for metabolic disorders and muscle-related health issues.
Excess fat stored inside skeletal muscle has become an important metabolic health concern. This type of fat buildup can be encouraged by high-fat diets, physical inactivity, and aging. Unlike fat stored under the skin, lipid droplets that accumulate within muscle cells can interfere with normal muscle function and make it harder for the body to efficiently use glucose and fatty acids. Over time, this reduced metabolic flexibility can contribute to insulin resistance. Finding ways to limit excess fat inside skeletal muscle could therefore be important for supporting healthy aging and reducing the risk of lifestyle-related disease.
