Different substitutions for saturated fat have different effects on risk of coronary heart disease CHD and need to be discussed separately. Delay the build-up of plaque a fatty substance in your arteries. All-cause mortality cardiovascular mortality fatal MIs myocardial infarctions non-fatal MIs stroke coronary heart disease mortality coronary heart disease events.

Replacing saturated fats with polyunsaturated fats decrease cholesterol levels The only 2 double-blind randomized trials in history failed to show that a low-saturated fat diet decreases heart disease 3 meta-analyses published in the past 3 years concluded no decrease in heart disease a ssociated with low saturated fat diet. A new review of published evidence challenges current guidelines that suggest in order to reduce heart disease risk people should generally restrict intake. One meta-analysis of 21 studies said that there was not enough evidence to conclude that saturated fat increases the risk of heart disease but that replacing saturated fat with polyunsaturated fat may indeed reduce risk of heart disease.

Major dietary sources of saturated fatty acids in the United States are full-fat dairy products and red meat 1. 1 And in 1961 the American Heart Association AHA recommended replacing saturated fatty acids SFAs with unsaturated fatty acids UFAs to prevent CVD. LDL cholesterol is a risk factor for heart disease and stroke.

1 However the study offers a unique twist by teasing. Saturated fat in the diet is associated with an increased risk of heart disease. A lower intake of saturated fat implies an increased intake of some other source of calories to maintain caloric balance.

The American Heart Association recommends aiming for a dietary pattern that achieves 5 to 6 of calories from saturated fat. In contrast a recent study from the Netherlands reported a 17 lower risk of ischaemic heart disease for each 5 increase in energy from SFA13 In this study replacement of 5 of energy from SFA with carbohydrate not necessarily whole grain high glycaemic index carbohydrate cis monounsaturated fatty acids polyunsaturated fatty acids or animal protein was associated with 27-37 higher risk of ischaemic heart disease. Saturated fat regardless of type linked with increased heart disease risk.

Only PUFA replacement of saturated fat lowers CHD events and CVD and total mortality. To clear the atherosclerosis in animals 6 when it is reduced in the diet. And likewise to reverse atherosclerosis in humans.

To assess the evidence for this recommendation meta-analyses. The scientific rationale for decreasing saturated fat in the diet has been and remains based on well-established effects of saturated fat to raise low-density lipoprotein LDL cholesterol a leading cause of atherosclerosis 4. Despite these recommendations heart disease rates which have been linked to saturated fat intake have steadily risen as have obesity and related diseases such as type 2 diabetes which.

78 In addition reducing saturated fat. Unhealthy saturated and trans fats can heighten your risk of heart disease by increasing the bad LDL cholesterol and lowering the good HDL cholesterol. Study results from the 1940s and 1950s suggest that the type and amount of fat play a major role in serum cholesterol levels.

Saturated fat intake has been linked to an increased risk of cardiovascular disease CVD and this effect is thought to be mediated primarily by increased concentrations of LDL cholesterol. High levels of LDL cholesterol in your blood increase your risk of heart disease and stroke.
