4-17 IAN Fat's not Fat

Taking fat to the test tube level. Fat is not just fat. 

 There is always a conundrum for me when I buy a steak. On the one hand, I worry relentlessly about my weight and staying slim. So in that context, trim all the fat off the steak and don’t go for marbling. On the other hand, everybody knows that tremendous flavor is associated with marbled steak. What is a guy to do? That’s where scientists come in. Texas Tech University Researcher, Dr. Brad Johnson Points out that in his research along with his colleagues fat is not just fat meaning that subcutaneous fat or back fat, which is the same kind of sad associated with a beer gut, is not the same as the fat in marbled steak. Listen carefully: “We have done a series of experiments that have clearly shown that the cells that make up marbling actually different than the cells that make up sub- cutaneous or back fat. In fact, they more closely match up with muscle cells than they do the back fat cells. That has allowed us to try to manipulate those cells in different ways and we are always taught that marbling or intra-muscular fast is the last fat to be deposited.”
