Lifestyle lower the mean cholesterol level Atherosclerosis modifiable risk factors such as lifestyle and nutritional behavior the extent of atherosclerosis plasma cholesterol CHD In high risk populations such as Finland or Scotland the rate of myocardial infarction is more than one order of magnitude higher than in low risk areas like China or Japan RISK FACTORS

Reduction of total mortality, cancer, coronary heart disease (CHD), and diabetes-associated mortality by intentional weight loss of 0.5–9 kg in non-smoking women with preexisting obesity related health conditions like diabetes or hypertension observed over 12 years RISK FACTORS Figure HDL cholesterol Cholesterol triglyceride levels Obesity Fat & Body Mass Index

Fat intake & Plasma lipids Japan Greenland Eskimos The high consumption of fish a major source of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) Omega-3 fatty acids lower coronary risk Their diet is rich in fat and cholesterol however contains a larger proportion of n-3 fatty acids from seal and whale The supplementation of 1 g of EPA and DHA reduction of fatal and non-fatal cardiac events between 10 and 30% RISK FACTORS Eicosapentaenoic and docosahexaenoic acid 5

17. Dietary fat In the Lifestyle Heart Trial rigorous lipid-lowering vegetarian diet Total fat intake : reduced from 31.5 to 6.8% of dietary energy The P/S-ratio >1 The amount of dietary cholesterol : reduced from 213 to 12.4 mg per day The intake of complex carbohydrates : raised to more than 70% of dietary energy Lost 10.9 kg LDL cholesterol levels decreased by 40% to about 100 mg/dl (2.6 mmol/l) significant changes in coronary angiograms were detectable RISK FACTORS
18. Dietary fat The Framingham study vegetarian diet reduced plasma cholesterol to levels of 125–135 mg/dl (3.2–3.5 mmol/l) Relationship Between Cholesterol and CHD Risk vegetarian diet weight lost reduction of hypertension reversal of insulin resistance RISK FACTORS Figure 0 25 50 75 100 125 150 <204 205-234 235-264 265-294 >295 CHD incidence per 1000 Serum cholesterol (mg/100 mL)
