Change of Diet We no longer forage for food Agribusiness Feeds the World We Eat Processed Food Destroys a percentage of nutritional value of food Pasteurization - Heat Introduces chemical preservatives alpha-tocopheryl acetate (Vitamn E) Use of Cheap, Plentiful Oils in Processed Food. Diminished Intake of Nutrients May Play a Role in Increased Prevalence of Certain Inflammatory Diseases

Polyunsaturated Fats Healthy Balance between Omega-3 and Omega-6 1:1 The average North American Diet is 1:10-1:20, Omega 6/ Omega 3 and as high as 1:50 This occurred when healthy unsaturated fats were replaced with trans fatty acids and diets full of processed foods (high in Omega-6)

Displacement Dietary ω-3 decreases tissue concentrations of ω-6, so there is less to form ω-6 eicosanoids. Competitive inhibition DGLA and EPA compete with AA for access to the cyclooxygenase and lipoxygenase enzymes. So the presence of DGLA and EPA in tissues lowers the output of AA's eicosanoids. Counteraction Some DGLA and EPA derived eicosanoids counteract their AA derived counterparts.

Over-abundance of Omega 6, in theory, allows the inflammatory response to become robust. Over-abundance of Omega 6, in theory, allows the inflammatory response to continue. A possible contributor to the increase in itis diseases
