There are a series of "What I've Learned" videos that you can find on You Tube. They are short and to the point. This one is a good summary of the fat/diet/cholesterol controversy.
Again another good video from the WIL (what I've learned) series of videos.
In the body fat (= triglycerides) is transported in the blood by lipoproteins. LDL which is supposed to be the bad cholesterol is a lipoprotein. We were told that if you eat a lot of saturated fat your LDL will go up. It turns out that the opposite is true.
Dave's presentation starts at 12:38.
If you are going to cut out the carbs you have to add in the fat. This video by Peter Attia discusses the fact that the evidence for the demonization of fat was not very good. Peter is in the process of writing a book ... I can't wait to read it.
Nina Teicholz is also an investigative journalist (like Gary Taubes) and she wrote the book "The Big Fat Surprise: Why Butter, Meat and Cheese Belong in a Healthy Diet". The book is about how the low fat food guidelines came about and why the government got it wrong. It is a very well written book.
This is a good video except for the end where it says that if you eat a diet high in saturated fat it will increase your LDL (the so called bad cholesterol). This is not necessarily true as Dave Feldman has shown in a video higher up on this page.
This video and the next video shows how ingested fats are processed in the intestine and then get delivered to different parts of the body for storage or burning.
This video is a continuation of the previous video. It also shows how the liver produces fat from sugar.
This is a good summary of what lipoproteins (which include LDL and HDL) do.
Omega 3 fats provide protection against heart disease - specifically the Omega 3 fatty acids DHA and EPA. You must, however, take these fats as supplements of fish oil or by eating fatty fish. The body does not do a good job of converting the main dietary non aquatic source of Omega 3 fat (alpha linolenic acid) into DHA and EPA.
This video is a bit technical but if you really want to know why the Omega 3 fatty acids DHA and EPA are good for you, and why Omega 6 fatty acids are inflammatory, then you should watch it.
