Diet: Saturated Fat
Diets high in animal foods containing saturated fat are associated with high serum cholesterol,60 plaque, excessive blood clotting in the arteries of the heart,61 and heart disease.62 Significant amounts of animal-based saturated fat are found in beef, pork, veal, poultry (particularly in poultry skins and dark meat), cheese, butter, ice cream, and all other forms of dairy products not labeled “fat free.” Avoiding consumption of these foods reduces cholesterol and has even been reported to reverse existing heart disease in conjunction with other lifestyle changes.63 In addition to large amounts of saturated fat from animal-based foods, Americans eat small amounts of saturated fat from coconut and palm oils. Palm oil has been reported to elevate cholesterol.64, 65 Research results regarding coconut oil are mixed, with some studies finding no link to heart disease66 and other trials finding that coconut oil elevates serum cholesterol.67, 68

Fijate en las fechas , este review que he puesto es de marzo de este año. Debes de tener en cuenta muchos factores a la hora de ver los estudios. Te pongo los resultados del que yo tengo.
RESULTS: During 5-23 y of follow-up of 347,747 subjects, 11,006 developed CHD or stroke. Intake of saturated fat was not associated with an increased risk of CHD, stroke, or CVD. The pooled relative risk estimates that compared extreme quantiles of saturated fat intake were 1.07 (95% CI: 0.96, 1.19; P = 0.22) for CHD, 0.81 (95% CI: 0.62, 1.05; P = 0.11) for stroke, and 1.00 (95% CI: 0.89, 1.11; P = 0.95) for CVD. Consideration of age, sex, and study quality did not change the results.
Resultados: durante un seguimiento de 5-23 años de 347,747 sujetos, 11,006 desarrollaron enfermedad coronaria, infarto o enfermedad cardiovascular. La ingesta de grasa saturada no estaba asociada al riesgo de ninguna de estas tres enfermedades. La edad, sexo y calidad de los estudios realizados no cambia los resultados obtenidos.
De nuevo gracias por aportar información interesante, asi es como da gusto discutir.
Saludos
