New research from the Cleveland Clinic points the cholesterol finger at a chemical found in red meat. That chemical compound is called carnitine, which through the digestive process, promotes hardening of the arteries.
Carnitine is found naturally in beef, lamb, duck and pork, but is also added to some energy drinks.
Experts say more study is needed on the potential long-term health impacts.
The study was published in the journal Nature Medicine.
