A new study suggests that a fondness for well-known fast-food and sugar-sweetened beverage brands can predict poorer diet quality, even among those who rate these brands as unhealthy. The research found that participants who liked fast-food brands not only consumed more fat and sugar but also tended to perceive those brands as healthier.
Research identifies MLKL as a protein that helps drive liver cancer associated with obesity-related fatty liver disease by reducing mitochondrial function, promoting tumor development. Removing MLKL reduces liver tumors but not fatty liver or liver inflammation, suggesting a new therapeutic target for liver cancer treatment
