Food Business • Intensive chicken and cow farming • antibiotics • fertilizers • GMOs • Pesticides • Preservatives • Relies on cheap raw materials such as corn, soy, wheat, sugar, palm oil
Inflammation:A common final pathway • Cardiovascular disease • Cancer • Neurodegenerative disease • Autoimmune disease • DM • Obesity
What is Inflammation? • Complex orchestration of pro-inflammatory and anti-inflammatory events • Mediated by eicosanoids • Prostaglandins, thromboxanes, leukotrienes, • Hydroxylated fatty acids, lipoxins, prostamides, isoprostanoids • Silent inflammation vs. painful inflammation
Phases of inflammation • Initiating event- • Pro-inflammatory attack response/cellular destruction • Anti-inflammatory healing response/Cellular rejuvenation

FAT IS GOOD!! • Depending on what kind…. • Omega 3 fatty acids (fish oils-EPA, DHA; plant sources -ALA) • Mono-unsaturated fats (canola and olive oils) • Decreased fat consumption since the 1960’s associated with obesity epidemic—CHO intake has increased dramatically • Glycemic index/glycemic load
Types of fats • Saturated: beef and other animal fats, dairy • Monounsaturated (omega-9): olive and canola oils
Polyunsaturated fats (essential FA’s): • Omega-6: Linoleic acid (LA)--vegetable oils, seeds, nuts Gamma Linolenic Acid (GLA)--borage and primrose oil Arachidonic Acid(AA)--meat products — Omega-3: Alpha Linolenic Acid (ALA)--legumes, leafy vegetables, flax, flaxseed and canola oils) Eicosopentanoic acid (EPA)-fish oil Docosahexanoic acid (DHA)--fish oil, breast milk
Avoid or Reduce • Trans-fatty acids BAD! • Omega-6 fatty acids • Margarine • Corn oil, cottonseed oil, grapeseed oil, peanut oil, safflower oil, sesame oil, soybean oil, sunflower oil, partially hydrogenated oils • Any product with long shelf life (crackers, pastries, chips)
How much Omega-3 fats do you need? • Strive for Omega 6: Omega-3 ratio of 4:1 (usual SAD (Standard American Diet) 16:1 • Maintenance 2.5 g/d • Improve hear function 5 g/d • Treat chronic pain 7.5 g/d • Treat neurological disease >10g/d Sears, The Anti-Inflammation Zone, 2005
Types of Fish Oil • Fish • Contamination with PCB, dioxin, and Hg • Higher in AA than fish oil • Crude fish oil • High contamination • Health food grade • Still some contamination with PCB’s and dioxins • Ultra-Refined EPA/DHA Concentrates • Removal of PCB’s and other toxins • Can be used in high doses (“weapons grade”)
Requirements for an Ultra-refined EPA/DHA concentrate • Total long-Chain Omega-3 >60% • Dioxins< 1 ppt • Mercury <10 ppb • PCB’s<30 ppb
What is an anti-inflammatory diet? • Lose fat • Eat small meals • Have some protein at every meal but reduce red meat and dairy (Avoid charred, overcooked foods) • Cold water fish (salmon, mackerel, sardines, herring) • Eat primarily fruits and vegetables • Leafy green vegetables, nuts, flaxseeds or oil • Take your fish oil
Anti-inflammatory Lifestyle • Exercise • Quit smoking • Weight loss • Stress management • Vagal nerve stimulation via abdominal breath work • Treatment of depression • Social support

Mediterranean Diet • More tolerable than low fat diets and associated with improved long term weight loss (McManus 2001) • Risk reduction of death from CAD = 0.67 compared to usual AHA diet (Trichopoulou et al, 2003)
American Heart Association Recommendations ·Healthy individuals should take two servings of fish(salmon, sardines, tuna, mackerel, trout) weekly along with flaxseed, canola, and soybean oil · Patients with CHD should consume higher doses, 1 g/d of EPA + DHA, which may require fish oil supplementation • Utilize complex carbohydrates, higher in fiber and lower in glycemic load to reduce risk of CHD AHA Recommendations: Intake of omega-3 fatty acids. Women’s Health in Primary Care. 2003.6(1): 25-26 (Consensus opinion) Hu F, Willett W.Optimal diets for prevention of coronary heart disease. JAMA. 2002;288:2569-2578 {Systematic review}
Indications from other studies • Eating fish as little as once a week reduces the risk of sudden death in men • Eating fish twice a week reduces CHD risk in women • Fish intake reduces Alzheimer’s risk Harper, Beyond the Mediterranean Diet: the Role of Omega-3 Fatty Acids in the Prevention of CAD, Prev Cardiol, 2003 Morris, Consumption of fish and n-3 fatty acids and risk of Alzheimer dz,. Arch Neurol, 2003
How intake of Omega-3 Fatty Acids is helpful • Stabilization of atherosclerotic plaques • Reduction of inflammation by mediation prostaglandin synthesis pathway • Improved ratio of omega-3 to omega 6 FA reduces arachidonic acid and pro-inflammatory, pro-platelet aggregatory cytokines • Enhances PGE1 and PGE 3 and less inflammatory leukotrienes(see diagram) Thies F, et al. Association of n-3 polyunsaturated fatty acids with stability of atherosclerotic plaque: RCT, Lancet, 2003;361:477-85 Harper, Beyond the Mediterranean Diet: the Role of Omega-3 Fatty Acids in the Prevention of CAD, Prev Cardiol, 2003;6(3):134-46
AHRQ study • Most studies show very low cardiovascular mortality in populations with high fish consumption • Strongest, most consistent effect of omega-3 fatty acids was reduction in triglycerides from 10-33%
A word about… • Glycemic Index (rate of absorption of glucose) • Glycemic Load (ratio between GI and CHO content) • www.glycemicindex.com
High Glycemic/Load Foods Increase: • Inflammation • Risks of heart disease, diabetes • Examples include: • White bread, glucose (GI= 100) • Potatoes, white rice • Pastries, white flour • Sweets, carbonated soft drinks
Lower GI/GL reduces risk • Whole grains • Fruits • Vegetables • Legumes • Or…mixing high GI/GL foods with those with lower GI/GL
