Smart Foods to Out Smart Aging PowerPoint
3/26/2016 Objectives—Smart Foods to Optimize Aging • Clarify foods that help with weight loss • Clarify how saturated fats impact risk for cardiovascular disease • Identify foods and nutrients that enhance cognitive function • Identify which fats are smart , neutral, and unhealthy • Identify which fats can tolerate higher heat cooking • Identify carbs and protein that are smart Smart Foods to Optimize Aging Steven Masley, MD, FAHA, FACN, FAAFP, CNS President, Masley Optimal Health Center Case Study My Background • A 51 year old woman with known heart disease has struggled to follow a low fat diet for the last decade and presents asking for an eating plan that would help her lose weight and prevent future cardiovascular events. She complains of cravings on a low fat eating plan and her recent blood work reveals elevated fasting glucose and triglyceride levels and small LDL and HDL particle size. • After increasing her intake of smart fat, fiber, and protein, she lost 20 pounds over 12 weeks and her fasting glucose, lipid particle sizes all returned to normal. Why were my original patients getting older and sicker over time? It isn’t from a lack of medical care. • I started as a regular family physician,,,,, • I watched my patients get older over time • Over time, I saw medical tragedies at work and at home,,,,,, • My salvation came from working overseas as a volunteer, working in restaurants, and devouring nutrition, heart, and aging research • Today, I can transform the life of my patients The Standard American Diet (SAD) Was Killing My Patients Over the last 20 years trying to follow a low-fat eating plan, nationally we have seen that: • • • • Weights and Waistlines are increasing We see an epidemic in rates of diabetes & pre-diabetes Memory loss is increasing Heart disease remains the #1 killer for both men and women—despite that lifestyle prevents 90% of CVD • And for the first time in history, our children are predicted to die younger than we are NEJM 2005. 1 3/26/2016 My Clinical Transformation Trimmer, Younger, Fitter RCT Intervention, 2006 Masley SC, Weaver W, Peri G, Phillips S.

Data for All Subjects with BMI>26 over 2.8 yrs ANTHROPOMETRIC • BMI: 29.3 • BP: 119/78 • Wt (lbs): 205.2 • BF(%): 29.4 FITNESS • VO2max 33.0 • ↓HR 1 min 25.7 NUTRIENT INTAKE • Fiber (gm/d) 18.8 • Vitamin D 534 • Potassium 2031 to to to to 28.4 117/77 198.3 (↓3.2 kg) 28.0 to to 34.4 30.7 to to to 24.4 1432 2271 Study Example: American College Nutrition 11/2015 Annual Mtg Abstract Objective: This study, “lifestyle factors that predict weight loss”. (2006-2015) Methods: • A prospective cross-sectional analysis of 157 subjects with a BMI ≥ 26.0, mean BMI =30.0 and age 51. • Subjects underwent health screening every 1-2 years at an outpatient center and completed a 3-day food diary at entry and on average 2.9 years later. • Subjects received a nutritional eval with individualized plans to correct nutrient deficiencies. • After fitness testing, they received a customized plan to exercise within their aerobic zone daily. Results: A dichotomous T-test showed: • The following factors predict weight loss: – Exercise minutes/week (p=0.02), – Intake of: • Fiber (p=0.0002), (preferably from vegetables, fruits, beans, and nuts; not flour sources) • vitamin D (p=0.047), • and potassium (p=0.031). Macronutrient Trends: 40 subjects, BMI>25, had BMI ↓2 points, and had >3 gram changes in fat and protein, and 2 gram change in fiber. Results not statistically valid, worthy of future study. Fat Intake: • When subjects ↓ fat intake by >3 grams daily, BMI ↓ 1.15 • When subjects ↑ fat intake by >3 grams daily, BMI ↓ 3.03 (>2.5x) Protein Intake: 2 point • When subjects ↓ protein intake by >3 grams, BMI ↓ 0.87 • When subjects ↑ protein intake by >3 grams BMI ↓2.35 (~3x) Fiber Intake: • When subjects ↓ fiber intake by >2 grams, BMI ↓ 0.786 BMI • When subjects ↑ fiber intake >2 grams, BMI ↓ 1.86 (>2x) BOTTOM LINE SUGGESTIONS: • To ↓ more weight: consider an ↑ in fat, protein, & fiber intake 4 3/26/2016 Study Conclusion: • An increase in exercise minutes/week and dietary intake of fiber, folate, vitamin D, and potassium predict sustained weight loss. • Further study is warranted to clarify weight loss benefits of increasing smart fat, protein, and fiber intake The Leading Cause of Mortality Is CVD, So to OutSmart Aging, You Need to Assess CVD Risk • Cholesterol is a risk factor for CVD • If you want to measure the progress of CVD, you need to look at the under lying cause – Which is arterial plaque • You can measure arterial plaque with cardiac CT • Even better is with carotid IMT testing—the only way to conveniently measure soft arterial plaque over time. Is plaque growth, shrinking, or staying the same. Carotid IMT How Do You Measure Arterial Plaque? • Stress testing: An ischemic response to ECG stress testing identifies when your arterial plaque is ~70% blocked. Although some patients will die before they reach this point. • Cardiac CT: Identifies old calcified plaque. Does not identify new, soft plaque, which is the most dangerous. A high score predicts futures CVD risk. Associated with radiation exposure. • Carotid IMT: Measures new soft plaque and can be done serially over time. • Outpatient procedure using an ultrasound transducer, 10 minutes to perform 10-15 images. • 10 minutes to interpret and determine a score. • Can assess current plaque age, and use to monitor plaque change over time. What Predicts Carotid IMT Growth? Masley SC. Emerging Risk Factors as Markers for Carotid Intima Media Thickness Scores. Journal of the American College of Nutrition 2015; 34: 100-107 IMT plaque lining is rough and thick before lifestyle intervention IMT plaque lining is smoother and thinner after 18 months of lifestyle intervention New Lifestyle Factors • Many factors predict IMT scores; the most powerful included: – Fitness (aerobic) – Fiber intake – Body Fat – Fish intake – Food nutrients Classic Risk Factors • Systolic blood pressure • Total cholesterol/HDL and TG/HDL ratios Surprisingly, the following don’t predict arterial plaque scores: • Total cholesterol • LDL cholesterol 5 3/26/2016 Is Arterial Plaque Regression Realistic? • Results: At the Masley Optimal Health Center, our average patient has had a decrease in IMT score -0.018 mm over 2.8 years, a 2.04% reduction. (In the USA, the average increase in IMT score is 1-1.5% per year) • The bivariate analyses showing a significant association with a ≥4% reduction in IMT in 62 of 288 subjects (the average reduction in this group was 10%); What About Your Brain? Another Critical Marker of Aging. Questions: Can You Improve Cognitive Function? How to Avoid Memory Loss? Results: The factors associated with a decrease in IMT score were: – A decrease in: BMI (p=0.047) or body fat (p=0.025) – A decrease in total cholesterol (TC) (p=0.031), LDL (p=0.028), TC/HDL (0.002), this relationship persisted whether subjects were Rx’d with a statin or not – More powerful was an increase in dietary intake of: magnesium (p=0.0001), fiber (p=0.017), vitamin D (p=0.016), vitamin K (p=0.001), potassium (p=0.001), & calcium (p=0.024). – With multivariate analyses, starting a statin med (p=0.0007), baseline IMT (p<0.0004), male gender (p=0.01), & years of follow up (p=0.008) were also all predictive of >4% IMT decrease; prior use of a statin med was NOT related to a reduction in carotid IMT score How Does Seafood Intake Impact Cognitive Function? Masley, Masley, Gualtieri. Effect of Mercury and Seafood Intake on Cognitive Function. Integrative Medicine 2012;11:32-40. • Reported cognitive benefits from long change omega-3 fats • Reported cognitive harm from mercury in big mouth fish • Epidemiologic studies have shown decreased Alzheimer’s rates with fish intake, and increased rates with mercury toxicity ALL STUDY DESIGN, SETTING, SUBJECTS, & MEASUREMENTS: Masley, Masley, Gualtieri.

Integrative Medicine 2012;11:32-40. • A retrospective, cross-sectional analysis of 384 men and women attending an all-day comprehensive physical evaluation. (Database now exceeds 1000 subjects) At their initial evaluation, measurements were made of body composition, cardiovascular status, fitness and diet (including specific types of seafood intake), and laboratory measures, including whole blood mercury. Each subject was tested with a computerized neurocognitive test battery, which is a computerized neurocognitive test battery comprised of seven familiar neuropsychological tests that generate ten independent scores.

Masley SC, Masley LV, Gualtieri T. Cardiovascular Biomarkers and Carotid IMT scores as Predictors of Cognitive Function. Journal of the American College of Nutrition 2014; 33: 63-69. • Multiple cardiovascular risk factors are associated with early cognitive decline. • Measures of complex information processing provide one of the earliest signs of cognitive decline and appear related to arterial plaque growth. • The following study will clarify how cardiovascular risk factors, lifestyle, and carotid intima media thickness (IMT) scores are associated with cognitive function and complex information processing scores. Conclusions Re Seafood & Hg Intake: • Excessive seafood intake, particularly large mouth fish, elevates mercury levels and causes cognitive dysfunction, especially at a mercury ≥15 µg/L. • Higher N3F3 intake is associated with improved cognitive function, yet N3FA intake from fish exercises a moderating effect that is ultimately overwhelmed by rising mercury levels. • You should measure whole blood or RBC mercury levels if your patients eat ≥3 large mouth servings per month of big mouth fish, or ≥3 servings of seafood per week of any fish. • I’d also encourage that you measure long chain omega-3 levels to ensure optimal intake without mercury toxicity.

Yes, more fat. And for those of you who remember the terms, Low-fat, fat-free, bad-fat—I recall those terms too. In fact, I was the medical director at the Pritikin Longevity center and that is part of what we taught—eat less fat. What Are the Potential Benefits of the Smart Food Eating Plan? My Promise to My Patients Is They Will: – Lose unwanted weight and keep it off – Feel and look better than ever – Control blood pressure, blood sugar, and cholesterol profiles – Prevent heart disease & shrink plaque – Improve brain function – Enhance sexual performance – Extend quality of life for decades What’s wrong with the low-fat message? • First, it is hard to do. I spent years telling people to lower their fat intake, and 95+% couldn’t do it. They weren’t satisfied and they couldn’t stick with it. • Second, the benefits from low fat diets (like Pritikin, Esselstyn, and Ornish) isn’t because they took out smart fats, but rather, they are better than the SAD because they are high in fiber, high in nutrients, and they got rid of unhealthy fats • Third, getting rid of smart fats was actually pretty dumb. Smart fats have two BIG amazing benefits. They decrease inflammation and they improve hormone levels. So when we cut out the Smart Fats, we became more inflamed and lost healthy sugar, insulin-appetite hormone balance, too 8 3/26/2016 This does not mean eating more fat of any kind is good, but only more fat if it is smart fat • There are three general kinds of fat – Smart fat – Neutral fats – Bad fats (OK, call them dumb fats) – So let’s clarify each More Bad Fat Controversy? • The third group of bad fats are those that have an excessive ratio (more than 4/1) of omega-6 fat to omega-3 fat, because more omega-6 fatty acids increase inflammation while omega-3 fatty acids lower inflammation. Both are PUFA fats. • Examples of fats with a high omega-6/omega-3 ratio are corn, soy, and cotton seed oil, and other grain and seed oils), which are common in feed lots • The challenge is some studies show better CVD outcomes with less PUFA fats and some show worse outcomes. I think the ratio is the key, but this remains controversial. Critical Publications: • Chowdhury R et al. Association of Dietary, Circulating, and Supplement Fatty Acids with Coronary Risk. Ann Intern Med 2014;160:398-406. – Landmark study, reviewed 49 observational studies and 27 randomized controlled trials – Overall, saturated fat intake is NOT associated with an increased risk for CVD – Substituting polyunsaturated fat for saturated fat does not protect against CVD – Increased blood levels of EPA and DHA intake (long chain omega-3 fats) are associated with decreased CVD risk, although data from supplement trials is mixed What are Bad Fats? • Bad fats have been shown to accelerate aging and harm our health • First are trans fats (hydrogenated fats), an perfect example of bad fats. The are used by the food industry to extend the shelf life of food, but shorten your lifespan if you eat them • What do I call hydrogenated fats?............... • A second form of bad fats are toxic fats are loaded with pesticides and hormones. Feed lots feed cows, pigs, and poultry pesticide-packed grain and those chemical accumulate in the fat. What are Neutral Fats? • Based upon recent published studies, neutral fats would now include clean sources of saturated fat • A couple examples of neutral fats are organic butter and cream, and fats from grass fed beef and cage-free organic-fed poultry • What about the idea that saturated fats are bad?....... Praagman J, et al. The association between dietary saturated fatty acids and ischemia heart disease depends on the type and source of fatty acid in the European Prospective Am J Clin Nutr 2016;103:356-65. – In a Dutch population eating clean animal fat, saturated fat is not associated with CVD rates. – Shorter chain saturated fats might be associated with a reduced risk (dairy fats versus meat fats); they could not control for statin use, so were only willing to say that the impact of SFAs was neutral, not beneficial. – Adding more PUFAs in place of saturated fat showed no benefit. 9 3/26/2016 Siri-Tarino PW et al. Meta-analysis of prospective cohort studies evaluating the association of saturated fat with CVD. Am J Clin Nutr 2010;91:502-9 and 535-46. • A review of 21 studies on MEDLINE on prospective dietary risk associated with CVD. • After 5-23 year follow up of 347,747 subjects, saturated fat intake was not associated with an increased risk for CVD. • Controlling for age and gender did not impact the results. Smart Fats • Smart Fats have clear proven clinical benefits—showing they improve how you age • Great examples of Smart Fats are: nuts, nut oils, olive oil, dark chocolate, avocado, and cold water seafood • What about coconut oil? Coconut fat is half smart and half neutral depending upon the person and health issues. So if you want to benefit your waistline, heart and brain, spend much more time cutting out sugar and flour intake, and less time worrying about “clean” saturated fat. Coconut is a good example of a beneficial saturated fat, but with ongoing controversy • Coconut has many benefits: –Great energy for athletes; the MCTs in coconut milk are great fuel. –Has anti-microbial benefits when eaten, fighting infections. –Coconut fats likely protect the brain, so people with brain injury or brain disease should eat more coconut fat HOWEVER; COCONUT FAT IMPACTS CVD RISK • Eating more coconut will raise LDL and Total Cholesterol levels, sometimes as much as 50-70 points. But HDL increases too, and the size of LDL and HDL is bigger, so overall many of these lipid changes with coconut intake appear beneficial • The problem is that we don’t have any clinic studies to prove this is a good thing, and at least one study showing a decrease in artery function with coconut fat intake, so honestly, there is still controversy about asking people with heart disease to eat more coconut oil and saturated fat How much smart fat do you need? – Nicholls SJ et al. Consumption of saturated fat impairs the anti-inflammatory properties of HDL lipoproteins and endothelial function. J Am Coll Cardiol. 2006; 48: 715–20. • To be safe, if established CVD, or are being treated for high cholesterol, I suggest avoiding coconut products and keep saturated fat intake moderate, until we have more clinical information, and enjoy the many other smart fats discussed 10 3/26/2016 Cooking with Oils Don’t Convert a Smart Fat into Toxic Fat • Beyond thinking about the health issues and flavors with cooking oils, a critical point is to think about what temperature they can be heated to without being damaged • The smoke point of an oil tells you at what temperature an oil is damaged • Heating an oil past its smoke point converts it from a potentially smart oil to a toxic oil What About Grilling? • The flame on a grill often exceeds 550 F, thus any fat dripping from meat, poultry, and fish into the flame is damaged fat, forming heterocyclic amines (cancer forming compounds) that are aerosolized on the food. • If you marinate meat, poultry, and fish for 10-15 minutes in an acidic solution, it can decrease heterocyclic amine formation by 70-80%, searing the outside of the meat so fats don’t drip and it won’t taste as dry • Orange & lemon juice, vinegar, buttermilk, and teriyaki sauce are good options, often improving the flavor, too. Food Group #2: Fabulous fiber • Benefits of fiber (nearly endless) • Weight loss • Improve your cholesterol, blood pressure, blood sugar • Support your microbiome (gut flora) • If you only made one choice, combining fiber and smart fat together is the #1 trick to optimize your health Common Oil Smoke points OIL SMOKE PT HEAT Almond 430 Avocado 520 Butter 350 Coconut 350 Grapeseed 485 Lard 380 Macadamia 400 Med-high High Med-low Med-low High Medium Med-high OIL SMOKE PT HEAT Virgin olive 420 Med-high Extra V olive 400 Medium Pecan 470 High Pistachio 250 Low Sesame 350 Med-low Walnut 320 Low Medium High Heat Cooking (sautéing for meat, poultry, and veggies) • Smart Fats – Avocado oil (OK to high heat) – Pecan oil (OK to high heat) – Almond and hazelnut oils – Virgin olive oil • Neutral Fats – Ghee (clarified butter) (OK to high heat) Aim for 10 Fiber serving/day = 30 gm Examples: • 1 cup of veggies has 3 grams of fiber (broccoli, asparagus, peas, kale, sweet potato • 1 cup of fruit (berries, apples, citrus, plums, and cherries) • 1 ounce (1 handful) of nuts • ¼ cup of beans (lentils, black beans, garbanzo) • 1 heaping Tbsp of seeds (chia, ground flax seed) 11 3/26/2016 How Glycemic Load Helps You Understand What Carbs to Choose and What to Avoid • Glycemic index tells you have much sugar is released from eating 50 grams of carbohydrate foods, but the problem is that without the quantity of food you should eat, it is deceiving • Glycemic load tells you how much sugar is released from eating one serving of a specific food • Eating a high glycemic load food raises blood sugar, insulin, and accelerates aging, especially for your heart and your brain • Classic examples are – – – – Carrots and beets, (HIGH GI, LOW GL) Bread (high GI and high GL) Cereal (high GI and high GL) Almost any grain that is ground into flour has a high GL • Bottom Line: The higher your glycemic load consumed, the faster you age. • Get to know the glycemic load of your food (gift idea) If you can’t find clean protein, then choose lean • You may be in a restaurant, with limited clean protein options • Nearly all the toxins in meat, protein, and dairy are in the fat. If you can’t get—grass fed, pasture raised, wild options, then pick lean, lower fat protein, as cutting down on the animal fat will make it cleaner • So think lean (like chicken and turkey breast, sirloin or tenderloin meat, and non-fat dairy) if you can’t find totally clean options • After all, eating lean is what doctors have been telling you for years, so this should be a familiar message Foods that are Double Smart • • • • • • • • • Beans Edamame (organic) Nuts Seeds Avocado Olives Salmon/Sardines Spices/Herbs Dark chocolate protein + fiber protein + fiber fat + fiber fat + fiber fat + fiber fat + fiber fat + protein fiber + flavor fiber + flavor + fat! Food Group #3: Clean Protein • Protein intake revs BMR and provides satiety. Examples: • Wild seafood • Cage-free, organic-fed poultry and eggs • Grass-fed beef • Grass-fed, organic raised dairy products • Beans • Fabulous protein powders (What’s my favorite breakfast?) • A Smart Fat Shake with clean protein and fiber! Food Group #4: Flavor • If you recall, I’m a trained chef. I know that if your food doesn’t taste delicious, you wont eat it. The key is helping you select food that tastes delicious, its easy to prepare, it meets your nutrient needs, and that your friends and family will love it. • The good news is that more flavor means healthier, as spices and herbs are packed with anti-inflammatory and anti-aging compounds. • And YES, in case you were wondering, as a trained chef (Seattle Four Seasons) I have tons of delicious recipes in my books. The New Rules on Food and Fat Are: 1. Distinguish between smart fat, neutral fat, and harmful fat. 2. Eat more smart fat. 3. It smarter to combine smart fat with more low glycemic load fiber, clean protein, and flavor from added herbs and spices. 4. Don't cook fat at the wrong temperature and change it from smart fat to toxic fat. 12 3/26/2016 Brief References: Contact me at [email protected] if you’d like a detailed reference list Putting it Together. What Could Be Easier? • It is so easy. All you need is 5/5/10 • Every day, just add: – Five servings of smart fat – Five servings of clean protein – And ten servings of fiber – Plus spices and herbs for flavor and health • • • • • • • • • • • 1.
