Clients in the News – UCLA researchers report Tomato Therapy to Improve Cholesterol

UCLA researchers report that tiny amounts of a specific type of lipid in the small intestine may play a greater role than previously thought in generating the high cholesterol levels and inflammation that lead to clogged arteries.

The team also found they could reduce the negative effects of these lipids in mice by feeding the animals a new genetically engineered tomato being developed at UCLA that is designed to mimic HDL (“good”) cholesterol.

The study, published in the December issue of the Journal of Lipid Research with an accompanying editorial, focused on a group of lipids found in the small intestine called unsaturated lysophosphatidic acids (LPAs).

“These lipids may be a new culprit that we can target in the small intestine in fighting atherosclerosis,” said senior author Dr. Alan Fogelman, executive chair of the department of medicine and director of the atherosclerosis research unit at the David Geffen School of Medicine at UCLA.

Big effect of small amount of LPA

Previously, it was thought that the role of the small intestine in response to a high-fat, high-cholesterol diet was simply to package the fat and cholesterol for transport to the liver. Once delivered to the liver, the large load of fat was thought to cause increased blood levels of LDL (“bad”) cholesterol, decreased levels of “good” cholesterol and the rise of systemic inflammation.
