The 1998 scientific research paper demonstrates that a diet containing only 0.33% cholesterol of which only 5% was oxidized, ie oil was fried over an over again, had resulted in a 100% increase in fatty streak lesions in the aorta of rabbits. This means that at  least since 1998 the scientists  knew that prolonged processing, heating or prolonged storage of cholesterol containing food accelerates atherosclerosis i.e. formation of arterial plaque. So what the food industry and the health department have done about it while cardiovascular diseases are on increase? Are the current health policies working?

Oxidized Cholesterol in the Diet Accelerates the Development of Aortic Atherosclerosis in Cholesterol-Fed Rabbits

Oxidized lipoproteins may play a role in atherosclerosis. Recently, we have demonstrated that the levels of oxidized fatty acids in the circulation correlate directly with the quantity of oxidized fatty acids in the diet and thatdietary oxidized fatty acids accelerate atherosclerosis in rabbits. The present study tests the hypothesis that oxidizedcholesterol in the diet accelerates the development of atherosclerosis. Rabbits were fed a diet containing 0.33%nonoxidized cholesterol (control diet) or the same diet containing 0.33% cholesterol of which 5% was oxidized(oxidized diet). Serum cholesterol levels increased to a similar extent in both groups, with the majority of cholesterolin the b-VLDL fraction. Moreover, in the serum b-VLDL fraction and liver, there was a significant increase in theoxidized cholesterol levels. Most importantly, feeding a diet enriched in oxidized cholesterol resulted in a 100% increasein fatty streak lesions in the aorta. Western diets contain high concentrations of oxidized cholesterol products, and our results suggest that these foods may be a risk factor for atherosclerosis.

The lifestyle guidelines to avoid formation of arterial plaque :







  • do not smoke
  • minimize intake of alcohol
  • exercise regularly and have active live
  • avoid stress and learn to manage it
  • Eat unprocessed food, fruits, vegetables, whole meal grains and breads
  • use unrefined, saturated: coconut oil, palm oil
  • use mono-unsaturated  oils like olive oil, canola, peanut oil,
  • use  polyunsaturared oils: safflower, sunflower, corn oil, cottonseed oil
  • consume unsalted nuts
  • eat cold water fish, avocados
  • watch the labels:  ” low in cholesterol”, “low in fat”  or ” low in sugar”, as they may be deceiving
  • eat low glycemic index food
