The American Heart Association promotes LDL-C as the best biomarker to predict heart disease and prefers low saturated fat diets to reduce it. However, they are possibly biased by the Seed Oil Industry.
Heart disease, also known as cardiovascular disease, refers to a range of conditions that affect the heart and blood vessels. It is a broad term that encompasses various conditions, including coronary artery disease, heart failure, arrhythmias, and valvular heart diseases, among others. Heart disease is a leading cause of death worldwide.
The diet-heart hypothesis, also known as the lipid hypothesis, proposes that there is a direct relationship between dietary fat intake, particularly saturated fat and cholesterol, and the development of heart disease. It suggests that consuming high amounts of these fats leads to an increase in blood cholesterol levels, specifically low-density lipoprotein (LDL) cholesterol, which in turn contributes to the formation of atherosclerotic plaques in the arteries. Some consider this hypothesis nothing more than wishful thinking.
Cholesterol is an animal based molecule that forms cell membranes. It's a lipid known as a sterol. Cholesterol is found in all animal foods and is healthy to eat, despite the opinions set forth by the diet-heart hypothesis. Lipoproteins carry cholesterol as well as other lipids.
Fat is a term used to describe a group of compounds known as lipids, which are organic molecules made up of carbon, hydrogen, and oxygen atoms. Fats are an essential part of our diet and play important roles in our bodies. Animal fats with low linoleic and arachidonic acids are preferred.
