Dietary guidelines are evidence-based recommendations that provide guidance on healthy eating patterns and lifestyle choices to promote overall health and prevent chronic diseases. These guidelines are typically developed by government agencies or expert committees and are updated periodically based on the latest scientific research. This site heavily questions basic assumptions within the dietary guidelines and shows conflicts of interest in their creation.
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.
