You have heard the saying that "knowledge is power," ut when it comes to the conversations about oils knowledge could be the difference between life and death. In today's episode, join Zane for a deep dive on what Oils to use and what Oils to avoid at all coast.    QUICK NOTES FROM ZANE: Avoiding PUFA vegetable oils Current meta analysis of RCT's and epidemiological studies shows no evidence to support the current diet heart hypothesis blaming saturated fat for heart disease Dietary cholesterol limits were removed from US guidelines Our bodies, via the liver and most cells, make the majority of its cholesterol We need to consider cholesterol quality rather than just quantity Inflammation in the lining of arteries creates an environment for small, dense and/or oxidized LDL particles to get caught in plaque formation Omega 6 vegetable oils are a cause of systemic inflammation Our ratio of Omega 6 to Omega 3 fats has increased from 10/1 to 25-50/1 since 1900 due to the introduction of processed Omega 6 fats into our diet Hateful 8: corn, cottonseed, canola, soy, safflower, sunflower, rice bran, grapeseed Polyunsaturated oils (PUFA's) are unstable and easily oxidized causing a free radical cascade in our bodies. Saturated fats are stable and not easily oxidized. Monounsaturated fats are not as easily oxidized as PUFA's Inflammation from an excess of Omega 6 fats increases risk of heart disease. Oxidized fats cause oxidation of LDL particles that are delivering them which increases the risk of those LDL particles getting caught in plaque formation. Recommendations: Reduce Omega 6 oils by not using them for cooking and avoiding processed foods where they are a main ingredient. Eat more wild-caught fish to increase Omega 3 intake. Cook with saturated fats like butter, ghee, lard, coconut oil, beef tallow, duck fat & use monounsaturated oils like olive and avocado oil.
