| bad fats - bad cholesterol |
|
"A diet high in saturated fats, trans fats and cholesterol tends to raise total blood cholesterol and LDL ("bad") cholesterol. A diet low in saturated fat, trans fat and cholesterol helps lower blood cholesterol levels. Dietary cholesterol is only found in foods from animals. Foods from plants, such as fruits and vegetables, don’t have cholesterol. Saturated fats are found in foods from animals. Some plant oils, commonly used in commercially baked goods and other food products, also are high in saturated fats. Many foods high in saturated fats are also high in cholesterol. Trans fats result from adding hydrogen to vegetable oils used in commercial baked goods and for cooking in most restaurants and fast-food chains."[1]
"The primary health risk identified for trans fat consumption is an elevated risk of coronary heart disease (CHD). A comprehensive review of studies of trans fats was published in 2006 in the New England Journal of Medicine reports a strong and reliable connection between trans fat consumption and CHD, concluding that "On a per-calorie basis, trans fats appear to increase the risk of CHD more than any other macronutrient, conferring a substantially increased risk at low levels of consumption (1 to 3 percent of total energy intake)". This study estimates that between 30,000 and 100,000 cardiac deaths per year in the United States are attributable to the consumption of trans fats.... Hu...reports on the benefits of reducing trans fat consumption. Replacing 2% of food energy from trans fat with non-trans unsaturated fats more than halves the risk of CHD (53%). By comparison, replacing a larger 5% of food energy from saturated fat with non-trans unsaturated fats reduces the risk of CHD by 43%." [2]

 One of the most practical web sites for understanding how to remove trans fats from restaurants and eating establishments who sell ready-to-eat meals to the public is produced by The New York City Department of Health and Mental Hygiene (DOHMH).

There is great diet information on the web site of The American Heart Association (AHA) recommendations regarding trans fats (hydrogenated fats).

The effect of olive oil polyphenols on antibodies against oxidized LDL. A randomized clinical trial
August, 2011
reported in Clinical Nutrition
Volume 30, Issue 4, August 2011, Pages 490-493
Reseachers: Olga Castańera, b, Montserrat Fitóa, M. Carmen López-Sabaterc, Henrik E. Poulsend, Kristiina Nyyssönene, Helmut Schrödera, Jukka T. Salonenf, Karina De la Torre-Carbotc, Hans-Franz Zunftg, Rafael De la Torrea, Hans Bäumlerh, Antonio V. Gaddii, Guillermo T. Saezj, Marta Tomása, Maria-Isabel Covasa and for the EUROLIVE Study Group
In this study demonstrated that daily consumption of 2 tablespoons of extra virgin olive oil reduces LDL (bad cholesterol). Extra virgin olive oil, with higher polyphenol levels, is more effective at reducing LDL that other olive oils with lower polyphenol levels.
The research showed increased the levels of an antibody that reduces levels of oxidized LDL cholesterol (bad cholesterol). High LDL is considered a risk factor of heart disease and stroke.
Olive oil polyphenols promote OLAB generation. This effect is stronger at higher concentrations of lipid oxidative damage.
