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.

Quick takeaways
Flawed control groups and inadequately controlled variables in human trials on seed oils make it difficult to draw accurate conclusions about their effects on cardiovascular outcomes.
Research suggests that seed oils, due to their higher linoleic acid content and susceptibility to oxidation, may lead to increased levels of oxidized LDL particles, which are associated with cardiovascular diseases and inflammation.

Flawed Human Randomized Controlled Trials on Seed Oils
The podcast episode delves into the numerous flaws in human randomized controlled trials that investigate the effects of seed oils on humans. The majority of these trials have flawed control groups that consume significantly higher amounts of trans fats or other inadequately controlled variables. These trials suggest that seed oils are harmful for cardiovascular outcomes.
Association of Seed Oils with Oxidized LDL
Research presented in the podcast highlights the association between seed oils and increased levels of oxidized LDL in humans. The higher linoleic acid content in seed oils makes the polyunsaturated fatty acids prone to oxidation, leading to the release of oxidized fatty acids in LDL particles. These oxidized LDL particles have been linked to cardiovascular diseases and inflammatory effects.
Concerns with Benzene, Heavy Metals, and Phthalates in Seed Oils
The podcast discusses the presence of benzene, heavy metals (such as cadmium and lead), and phthalates in seed oils. These contaminants can have detrimental health effects, including a potential association with cancer. Cooking fumes produced by seed oils have been linked to cervical cancer and other cancers as well.
Critique of Arguments on Insulin Sensitivity and Flow-Mediated Dilatation
The arguments presented by proponents of seed oils in regards to insulin sensitivity and flow-mediated dilatation are called into question. The podcast highlights the flaws in studies that suggest seed oils are superior to saturated fats in improving insulin sensitivity and endothelial function. Additionally, research is presented to support the hypothesis that increased linoleic acid from seed oils can lead to pathological insulin resistance in the long term.
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.
