Ancel Keys: Total fat, Saturated fat, dietary cholesterol primary cause 1967 Review ArYcle published in New England Journal of Medicine downplaying the link between sugar and heart disease and emphasized the role of saturated fats and heart disease 1980s: 1980 dietary Guidelines for Americans focused on reducing total fat, saturated fat, and dietary cholesterol

21 a. Vegetables and fruit are the only characteristics of the diet that were consistently identified in every conclusion statement across the health outcomes. b. Whole grains were identified slightly less consistently compared to vegetables and fruits, but were identified in every conclusion with moderate to strong evidence. c. Low- or non-fat dairy, seafood, legumes, nuts, and alcohol were identified as beneficial characteristics of the diet for some, but not all, outcomes d. Higher intake of red and processed meats was identified as detrimental compared to lower intake. e. Higher consumption of sugar-sweetened foods and beverages as well as refined grains was identified as detrimental in almost all conclusion statements with moderate to strong evidence.

31 THE REPORT DID NOT FOR THE FIRST TIME PUT A LIMIT ON TOTAL FAT or LIST TOTAL FAT AS A NUTRIENT OF CONCERN 1. Saturated Fatty Acids and effects related to CVD/lipoproteins: Strong Evidence. a. Strong and consistent evidence from RCTs and prospective cohort studies shows that replacing SFA with PUFA reduces total and LDL-C and the risk of CV events and coronary mortality. b. Replacing SFA with CHO reduces total and LDL-C, but increases TG and reduces HDL-C. c. Reducing total fat with CHO does not lower CVD risk. d. Consistent evidence from prospective cohort studies shows that higher SFA intake compared to CHO is associated with similar CVD risk. e. For every 1% of energy intake from SFA replaced with PUFA, incidence of CHD is reduced by 2 to 3%

43 What do we replace the saturated fats with? Carbohydrates ( Refined vs Unrefined) Omega 6 Polyunsaturated fats ( Linoleic Acid in Vegetable oils) American Heart AssociaYon supports Cardiovascular Heart Study ( 4707 parycipants followed for 18 years had higher linoleic levels and had a decrease of all cause of death) Not all research supports. Linoleic acid ( omega 6 converts to AA) Omega 3 Polyunsaturated fats ( Salmon, Fish oil Supplements) Higher levels are linked to lower risk of CVD related outcomes, TG, Blood pressure, Heart rate, and endothelial funcyon Monounsaturated fats ( Olive Oil, avocados, pistachios) Those with the highest intake of olive oil have a 9% reducyon in death from CV events, 17% reducyon in stoke, 11% all cause of death. Replacing 5% of energy from saturated fats with MUFAs is associated with 13% reducyon in total mortality

56 Summary review. Nutrition Reviews Vol. 74(4): , 2016 Twenty-one research papers were identified for inclusion in the review: 8 clinical trials and 13 observational studies. The majority examined the effect of coconut oil or coconut products on serum lipid profiles. Coconut oil generally raised total and low-density lipoprotein cholesterol to a greater extent than cis unsaturated plant oils, but to a lesser extent than butter. The effect of coconut consumption on the ratio of total cholesterol to high-density lipoprotein cholesterol was often not examined. Observational evidence suggests that consumption of coconut flesh or squeezed coconut in the context of traditional dietary patterns does not lead to adverse cardiovascular outcomes. However, due to large differences in dietary and lifestyle patterns, these findings cannot be applied to a typical Western diet. Overall, the weight of the evidence from intervention studies to date suggests that replacing coconut oil with cis unsaturated fats would alter blood lipid profiles in a manner consistent with a reduction in risk factors for cardiovascular disease.
