104. Linoleic acid and metabolic disease

The discussion over what aspect of our diet has been driving the escalation of metabolic disease over the last 100 years has been a confusing one full of contradictory information. It would be logical to look for a change in our diet associated with such a dramatic change in the health of a population There are both correlated evidence and dietary trials to support the theory that the increase in linoleic acid, provided by the introduction of PUFA processed oils into our diet, is the driver. In this episode of Hunger Hunt Feast, I want to share a collection of them to help clarify some of the confusion. -- Episode Specific Links:  Linoleic acid concentrations in fats and oils http://www.distributionkatrina.com/english/comparison-of-dietary-fats.html Increase in Adipose Tissue Linoleic Acid of US Adults in the Last Half-Century https://www.ncbi.nlm.nih.gov/labs/pmc/articles/PMC4642429/ Composition of adipose tissue and marrow fat in humans by 1H NMR at 7 Tesla https://www.sciencedirect.com/science/article/pii/S0022227520346733 Diets could prevent many diseases https://www.researchgate.net/publication/10673140_Diets_could_prevent_many_diseases Corn Oil in Treatment of Ischemic Heart Disease https://ncbi.nlm.nih.gov/pmc/articles/PMC2166702/ Linoleic acid causes greater weight gain than saturated fat without hypothalamic inflammation in the male mouse https://pubmed.ncbi.nlm.nih.gov/27886622/#:~:text=the%20male%20mouse-,Linoleic%20acid%20causes%20greater%20weight%20gain%20than%20saturated%20fat%20without,doi%3A%2010.1016%2Fj Effects of fatty acids on mitochondria: implications for cell death https://pubmed.ncbi.nlm.nih.gov/12206909/ Can linoleic acid contribute to coronary artery disease? https://pubmed.ncbi.nlm.nih.gov/8192728/ Effects of linoleate-enriched and oleate-enriched diets in combination with alpha-tocopherol on the susceptibility of LDL and LDL subfractions to oxidative modification in humans https://pubmed.ncbi.nlm.nih.gov/8148354/ Acrolein is a product of lipid peroxidation reaction https://www.jbc.org/article/S0021-9258(18)80708-6/fulltext#seccestitle90 The role of dietary oxidized cholesterol and oxidized fatty acids in the development of atherosclerosis https://pubmed.ncbi.nlm.nih.gov/16270280/ Rapeseed oil and sunflower oil diets enhance platelet in vitro aggregation and thromboxane production in healthy men when compared with milk fat or habitual diets https://pubmed.ncbi.nlm.nih.gov/1641826/ Stearoyl-CoA Desaturase-1 Is Associated with Insulin Resistance in Morbidly Obese Subjects https://link.springer.com/article/10.2119/molm
