Objectives/Presentation Outline
1) Coronary heart disease risk factors in Asian Indians
2) Evidence based diet & lifestyle recommendations to lower heart disease risk in Asian Indians
3) Good and bad fats within the context of a heart healthy diet
South Asia at Health Crossroads World Bank Report: February
2011
Asian-Indians (India, Pakistan, Bangladesh, Sri lanka & Nepal) 3 X more likely to develop diabetes.
Diabetes doubles risk of heart disease in men & quadruples risk in women.
First heart attack in Asian Indians: six years younger versus rest of the world (53 vs. 59 years)
www.worldbank.org/sarncdreport
Are Women at Risk for Heart Disease?
Heart disease is ALSO the leading cause of death in women in every major developed country e.g. US and also in most emerging economies.
The myth that heart disease is only a “man’s disease” has been debunked.
Risk Factors for Heart Disease and Stroke
What are “risk factors” ?
BehaviorsBehaviors or conditionsconditions that increase increase your chances of developing a disease.
Example: Being inactive Being inactive is a riskrisk factorfactor for heart diseaseand stroke.
Metabolic Syndrome
Primary Cause of Increased CHD Risk in Asian Indians
Higher prevalence of high triglycerides, low HDL-C, glucose intolerance & central obesity.
MetS increases risk for heart disease at any LDL level
Pre-diabetes or Insulin Resistance Syndrome Enas EA. Brit J of Diabetes and Vascular Dis 2005
Metabolic Syndrome: Diagnostic Criteria: 3 or more
Central obesity (waist circumference)• Men > 40 inches (Asian Indians 35.4”)• Women > 35 inches (Asian Indians 31.5”)
Triglycerides > 150 HDL men < 40 women < 50 Blood Pressure >130/85Impaired fasting glucose: 100-125
Grundy SM et al Circulation. 2004
Goals for Heart Health Control the ABC’s:
A1C
Blood pressure
Cholesterol/lipids
Maintain a desirable weight Stop smoking

Weight Loss Reduces Risk
Improves blood cholesterol Lowers total and LDL cholesterol Lowers triglycerides Raises HDL cholesterol
Reduces blood pressure Makes your insulin work better (improves effectiveness in the body) Lowers blood glucose
AHA 2006 Diet & Lifestyle Recommendations
Achieve a healthy weight Decrease total fat, saturated fat total fat, saturated fat and
trans fats. trans fats. Replace with unsaturated unsaturated fats and oilsfats and oils
Increase intake of omega 3 fatty acids Increase intake of plant stanol esters Consume nutsnuts and soy proteinsoy protein Increase intake of viscous fiberviscous fiber Lichtenstein et al Circulation 2006
American Heart Association 2020 Dietary Goals
Primary Fruits & Vegetables: ≥ 4.5 cups/day Fish: ≥ two 3.5 oz. servings/week (preferably oily fish) Fiber-rich whole grains (≥ 1.1 g of fiber/10 g of CHO: ≥ three 1
oz. equivalent servings per day) Sodium: < 1500 mg/day Secondary Sugar-sweetened beverages: ≤ 450 kcal (36 oz.)/week Nuts, legumes, & seeds: ≥ 4 servings/week Processed meats: none or ≤ 2 servings/week Saturated fat: < 7% of total energy intake Lloyd-Jones et al. Circulation 2010
The Portfolio Eating Plan to lower LDL-C
• NCEP Guidelines:
– Saturated fat < 7% kcal
– Cholesterol < 200 mg/day
• 1.0 g plant sterols/1000 kcal
• 9.8 g viscous fibers/1000 kcal
• 21.4 g soy protein/1000 kcal
• 14 g whole almonds/1000 kcal• Jenkins DJ, JAMA. 2003
Effect of Portfolio Eating Plan on LDL Reduction
10 g psyllium (viscous fiber) lowered LDL 6-7%
45 g soy proteins reduced LDL 12.5% 1-2 g plant sterols reduced LDL 13% 10 g almonds lowered LDL-C 1% Similar to the effect of statins
Jenkins DJ, JAMA. 2003
Lowering Triglyceride
Lose weight (belly fat)
Increase physical activity
Control blood sugar
Limit: Refined carbs/simple sugars Alcohol Total fat (if TG very high)
Omega 3 fatty acids (fish oils)

Weight loss 10 lbs: improve BP, LDL-C, TG, HDL-C, A1c, fasting glucose
Recommendations to Lower Raj’s LDL-C: TLC Diet
Decrease saturated and trans fats, dietary cholesterol Lose weight Increase
Total Fiber (20-30 grams a day) Soluble Fiber (~10 grams a day) Plant stanol/sterol (2 grams a day) Activity (30 minutes most days/week) Sikand G 2011 “Nutrition, Health & Diabetes” AAPI 2nd
edition. Preventing Heart Disease in Asian Indians: Diet & Lifestyle Recommendations
Lifestyle Changes for Raj to consider
Diet : Keep a food log Limit/choose lean meat,
poultry (5 - 6oz. day) 2 or 3 servings of non-fat
or low fat dairy products Include fish 2x/week Increase fruits &
vegetables Small serving of nuts Focus on portion control
Exercise Keep a physical activity
log
Begin a walking program and gradually increase to 35 minutes per day
Use a pedometer and set a goal to increase 250 steps/day up to 10,000 steps
TLC Diet Options for Raj
Increase intake of viscous (soluble) fiber: 10-25g per day Sources of soluble fiber include:
Oats Dried beans Fruits/vegetables (eg.strawberries, bhindi, baingan)
2 tbsp plant sterol/stanol esters Sources include:
Benecol, Promise activReducing sodium and alcohol intake

Food Components to Reduce Fat
Saturated fatty acids—less than 10% of calories• Less than 7% reduces risk of CVD further• Replace with poly- and monounsaturated
fatty acids (not with sugar or refined grain) Trans fats—as low as possible Cholesterol—less than 300 mg per day
• Effect small compared to saturated and trans fats new
• Egg yolks—up to 1 per day new
Aim for 25 – 35 gm Dietary Fiber per day
Starchy beans/lentils: Aim for ½ cup cooked beans in 3 - 5 meals per week
Oatmeal, oat bran, barley, brown rice, Quinoa
Vegetables and fruits (eat edible skin)
Aim for 2 ½ c. veggies and 2 c. fruits a day Whole grain breads, crackers and cereals
with at least 5 gm of Dietary Fiber5 gm of Dietary Fiber per serving
Psyllium seeds (Metamucil)
Foods Containing Viscous or Soluble Fiber: 10 – 25 gm/day
Oats Barley Lentils (daals) Legumes (rajma, channa, black eyed beans) Prunes, Apples Rye bread, pumpernickel bread Supplemental fiber: Metamucil® and
Citrucel®. (Not all fiber laxatives lower cholesterol)
Limit Saturated Fats: “Bad” Fats
Raise LDL
Solid at room temperature Whole milk & whole milk dairy products:
butter, paneer, cheese, cream, ice-cream, whole milk yogurt, desserts made with whole milk e.g. khoa, kulfi, kheer
Fatty cuts of lamb, pork, beef, poultry with skin, lard, bacon, sausage, hotdogs
Palm oil, palm kernel oil and coconut oils
Trans-fats: “Bad” Fats Raise LDL & Lower HDL
Processing changes vegetable oils into semi-solid fats e.g. partially hydrogenated fats
Re-use of oil in cooking/frying e.g. commercially prepared snacks e.g. samosas, bhajias, chevda, bhel etc
French fries, fried chicken, onion rings Stick margarine, shortening, vanaspati Baked goods: cakes, donuts, cookies
Monounsaturated Fats : Good Fats Lower LDL
May help raise HDL (good) cholesterol.
Olive oil, canola oil, peanut oil Avocados Nuts: almonds, peanuts, pecans,
pistachios, hazelnuts Is EVOO good for cooking?
Omega-6 Polyunsaturated fats: Good Fats Lower LDL
Lower LDL (bad) cholesterol when used in place of saturated fat.
Corn oil, safflower oil, sunflower oil Sunflower seeds
Plant Stanols/Sterols lower LDL-C 10%
Adjunct therapy to diet and medication eg. Bennecol spread, Smart balance Heart Right spread, Promise activ spread, fortified in orange juice & in health bars e.g. Kardea bars
Naturally found in vegetable oils, nuts, legumes, whole grains, fruits, vegetables; yet in small amounts, making it difficult to get recommended amounts

Omega-3 Fats: Good Fats Lower Risk of Heart Disease &
TG
Two servings (3.5 oz each) of fatty fish per week are associated with a 30-40% reduced risk of death from heart attack or stroke
Lower triglycerides
Associated with ↓ sudden death (ACS)
Salmon, mackarel, sardines, rainbow trout, herring, halibut & albacore tuna
Fish Oil SupplementationFish Oil Supplementation
Recommendations
3-4 oz fatty fish/day or
1-3 g omega 3 fatty acids per day (for heart health and TG lowering)
FDA: 3 g omega 3 fatty acids a day (with no more than 2 g per day from a dietary supplement)
Look for 1g fish oil capsules contain 180 mg of EPA and 120 mg DHA
Plant Sources of Omega-3 Fat2-3 gm/day of ALA Decreases Risk
Canola oil 1TBS = 0.94 g/serving Ground flax seeds 1 TBS=1.6 g/serving Flaxseed oil 1 TBS=7.3 g/serving English walnuts 1 TBS (7 halves) = 2.6
g/serving Soybean oil 1 TBS =0.94 g/serving Chia seeds (sabza) 1 tsp =1.7
gm/serving
Raising HDL (Good) Cholesterol
Be physically active Lose weight if overweight Decrease refined carbs Moderate fat intake Increase monounsaturated fats Do not smoke
Food Sources
Potassium Vegetables (potatoes, tomatoes, spinach, broccoli,
acorn squash, collard & mustard greens) Fruits (grapefruit, orange, banana, watermelon,
strawberries) Caution for use in those with kidney disease
Magnesium Vegetables (spinach, broccoli, green beans, tomato
juice; navy and pinto beans) Whole grains (100% whole wheat bread, crackers) Other (tofu, halibut)
Decrease Sodium/ Increase Decrease Sodium/ Increase PotassiumPotassium
Limit sodium from ALL foods to 2,300 mg (~1 tsp. salt) per day or 1500
mg/day (at risk, older, HTN) Consume potassium richpotassium rich foods: low fat low fat
milkmilk, fruitsfruits and vegetablesvegetables
Strategies to Lower Salt Intake
o Become aware of salt content in food eg ketchup, soy sauce, pickles, chutneys. Read labels.
Cook with little or no salt. Refrain from adding salt at the table
Avoid processed salty foods eg snack mixes bhel, chevda, nuts
Use spices & lemon instead of salt Rinse canned foods e.g. beans Use no-salt-added food products – read labels
2010 US Dietary Guidelines: Summary
Enjoy your food, but eat less. Reduce calories from solid fats and added sugars (SoFAS)
Choose foods high in potassium, dietary fiber, calcium & vitamin D. Make half your plate fruits & vegetables.
Maintain a healthy weight. Perform regular physical activity.
Switch to fat free or low fat milk (1%). Reduce salt by comparing sodium in foods e.g. soup,
bread & frozen meals & choose foods with lower numbers. Drink water instead of sweetened beverages. www.dietaryguidelines.gov
