Proteoglycans, transcytosis and the role of inflammation

If you are interested in lipids, you’ve probably heard of Dave Feldman and his work. If not,  you’ve got some homework to do, and I think you’ll be  amazed at what you find. Dave’s work can be found at cholesterolcode.com where he details his multiple, meticulous self-experimental projects. Prior to cholesterol adventures Dave was a senior software scientist and an engineer. He brings this “out of the box” thinking to the world of medicine and we are all better off for it. 

He began a low-carb, high-fat diet in April 2015 and has since learned everything he could about it with special emphasis on cholesterol. He saw his own lipid numbers spike substantially after going on the diet and spotted a pattern in the lipid system that’s very similar to distributed objects in networks.
