Washington: There may be a biological reason why fatty and cholesterol-rich foods such as buttery shrimp, fried eggs, burgers and fries are so appealing together, suggests a new study.It has been known for more than 40 years that dietary fat promotes cholesterol uptake, but fundamental aspects of that process remain poorly understood.James Walters, Ph.D., and his colleagues at the Carnegie Institution for Science are using zebrafish to better understand the cellular mechanisms of cholesterol processing and have discovered a surprising link between dietary fat and cholesterol absorption.“One reason these questions remain unknown is because of the difficulty of studying such a complex biological system as the intestine,” which in addition to multiple cell types also includes a diverse array of enzymes, mucus, and symbiotic bacteria, he said in a June 20 presentation at the ongoing 2012 International Zebrafish Development and Genetics Conference in Madison, Wisconsin.
