A natural compound found in blueberries and grapes may help muscle cells break down stored fat, new research suggests.
uncertain
research → find → fat
In laboratory experiments conducted in Japan, researchers found that the compound, called pterostilbene, reduced fat accumulation in cultured mouse muscle cells.
asserted
compound → conduct → cells
Pterostilbene is a naturally occurring antioxidant found in blueberries, grapes and other types of berries.
asserted
Pterostilbene → occur → berries
While previous research linked it to metabolic benefits, little was known about how it could affect skeletal muscle.
uncertain
it → link → muscle
The new findings, published Sept. 1 in the journal Food Bioscience, suggest that pterostilbene reduced abnormal fat buildup by encouraging cells to break down fat already stored in the cells.
asserted
pterostilbene → publish → cells
Fat buildup can result from high-fat diets, inactivity and aging, according to a news release.
uncertain
buildup → result → release
Too much fat inside muscle cells can interfere with how the body uses glucose and fatty acids and may contribute to insulin resistance.
"Our findings establish a scientific framework for developing functional foods and nutritional supplements that target muscle fat metabolism," lead researcher Takakazu Mitani, an associate professor at Shinshu University, said in a statement.
uncertain
Mitani → interfere → statement
The team screened several food-derived compounds in the cells and found that pterostilbene caused the strongest reduction in fat accumulation without disrupting muscle growth.
asserted
pterostilbene → screen → growth
It appeared to preserve a protein, PPAR-delta, that helps regulate how cells process fat, according to the study.
uncertain
cells → appear → study
The research also provides an "experimental framework" for identifying other natural compounds that protect PPAR-delta, Mitani added.
asserted
Mitani → provide → delta
While the findings provide a starting point for studying dietary approaches that could one day help address obesity, type 2 diabetes and age-related metabolic decline, future studies in humans and animals are needed to determine whether the effect translates beyond lab-grown cells.
uncertain
effect → provide → cells
Using a cell model "strips away the complexity of human metabolism," Johannah Katz, a registered dietitian from Florida, told Fox News Digital.
asserted
Katz → use → Digital
"In people, pterostilbene has to be digested, absorbed, metabolized, circulated and actually reach muscle tissue at an effective dose," she said.
asserted
she → have → dose
"We also can't assume mouse muscle cells will respond exactly like human muscle.
asserted
cells → assume → muscle
While the study identified a potential mechanism that may help explain reduced fat accumulation in cells, that is different from showing that eating blueberries or taking pterostilbene supplements directly leads to fat loss, Katz added.
uncertain
Katz → identify → loss
"Blueberries and grapes are nutritious foods for many reasons, but this study alone doesn't show that eating more of them will reduce fat buildup in human muscle," she said.
asserted
she → show → muscle
Fox News Digital reached out to the study authors for comment.
asserted
Digital → reach → comment
