See-through fish fed junk food diet develops early symptoms of heart disease

"A transparent fish that was fed junk food has allowed scientists to watch blood vessels furring up and narrowing. They hope the research will improve understanding of how heart disease develops in humans. The zebrafish were given a high cholesterol diet which led plaque deposits to build up in their blood vessels. In humans the same process, called atherosclerosis, causes the thickening and hardening of artery walls. Risk factors for atherosclerosis include high levels of 'bad' cholesterol, high blood pressure, smoking, diabetes and a family history of the disease. Narrowed arteries increase the chances of suffering a heart attack or stroke" - Mail Online
