243. Responding to Layne Norton on SEED OILS

Dec 27, 2023

In this podcast, the host responds to Layne Norton's video on seed oils and discusses flaws in the trials. They analyze the harm of seed oils on cardiovascular health, highlighting increased oxidized LDL levels and inflammation. The negative effects of linoleic acid on the body, including obesity, are explored. Studies on the effects of high and low fat beef consumption on vascular function and blood pressure are also discussed.

Seed Oil Meta-Analyses Scrutiny

Paul Saladino disagrees with Layne Norton's neutral/positive stance on seed oils, citing flawed meta-analyses.
He emphasizes the importance of scrutinizing individual studies within these analyses.

INSIGHT

Flawed Control Groups in Seed Oil Studies

Most studies showing neutral/beneficial seed oil effects have flawed control groups with higher trans fat intake.
Saladino suggests only a few seed oil trials are valid due to these control group issues.

LA Veterans Trial Flaws

The LA Veterans Administration trial, often cited as proof of seed oils' harmlessness, has flaws like differing vitamin E and smoking rates between groups.
This questions the validity of using this trial to support seed oil consumption.

This episode is my response to Layne’s video about seed oils. Due to the pervasive mainstream support for seed oils, I believe it’s extremely important to shed some light on the hidden truth behind these oils. There is a lot of conflicting evidence on seed oils out there. Looking at the totality of the evidence can be very misleading, so we must look at the details. By thoroughly breaking down each trial from Layne’s video, we can see massive flaws in the methods and designs of each study. Trans fat consumption by the control group and multifactorial interventions in the experimental group were the primary confounding variables. In this video, Paul references several studies suggesting different ways in which seed oils are harmful to humans. He always appreciate differing views and these discussions because it’s how we all learn. He has hope that a respectful debate will happen in the future so that we can dive deeper into this important subject. He strongly believe that seed oils are evolutionarily inconsistent, these are not the fats that humans have evolved on. In fact, we have evolved by consuming ample amounts of animal fats, rich in saturated fats. Saturated fats have been shown to lower markers of heart disease and they are an amazing source of essential vitamins like A, D3, K2, E. It's always meat / organs / fruit / honey / raw dairy. This is an ANIMAL-BASED diet, and I believe this is the most optimal diet for humans on the planet. Check out my ANIMAL-BASED CALCULATOR here: https://www.paulsaladinomd.co/ab-guide
