Outline History of Nutrition Recommendations Role of Medical Nutrition Therapy Nutrition Care Plan Nutrition Recommendations Implementing Behavior Change Debunking Nutrition Myths HISTORY OF NUTRITION RECOMMENDATIONS 1 5/10/2013 History of Nutrition Recommendations Starvation Diets Exchange Lists For Meal Planning Caloric Level Meal Plans ADA Diet Principles of Nutrition and Dietary Recommendations for Individuals With Diabetes Mellitus Carbohydrate Counting Starvation Diets Also called the Allen Plan, after Frederick Allen and Elliott Joslin. Used from 1915 to 1922, before the discovery of insulin. ◦ The Th only l treatment t t t for f diabetes di b t att this thi ti time. Based on repeated fasting and prolonged undernourishment. Fasting reduced glucose levels, but prolonged calorie restriction led to inanition. (Muzur, 2011). Starvation Diets (Bliss 1982) 2 5/10/2013 Before & After Insulin Therapy (Bliss 1982) Exchange Lists for Meal Planning Published in 1950 by the joint effort of the American Diabetes Association, Academy of Nutrition and Dietetics, and the U.S. Public Health Service. Meal planning method in which foods are grouped into six lists- starch, fruit, milk, vegetables, meat and meat substitutes, and fat. ◦ Each list is a group of measured foods of approximately the same nutritional value. ◦ Foods on the same list can be “exchanged” for one another. (Mahan 2008) Exchange Lists for Meal Planning (Mahan 2008) 3 5/10/2013 Calorie Level Meal Plans Shortly after the Exchange Lists for Meal Planning was published, meal plans with specific calorie levels were created to accompany the exchange list meal plan for diabetes. Meal p plans: ◦ 1,200, 1,500, 1,800, 2,200, 2,600 became available for adults and children. ◦ Meals plans included: Tables detailing grams of carbohydrate, protein, and fat for each calorie levels. Purpose of these preplanned diets were to assist nutrition educators. (Schafer, et al 1997) American Diabetes Association Diet (ADA) Before 1994, the ADA diet focused on prescribed percentages of macronutrient intake: Example: 1800 ADA diet 50% carbohydrate (255 g) 20% protein (90 g) 30% fat (60 g) Shortcoming to this approach is that the prescribed “diet” cannot be individualized: ◦ lacks relevance to the patient’s lifestyle ◦ does not consider the patient’s culture ◦ disregards the patient’s socioeconomic status (Mahan 2008) American Diabetes Association Diet (ADA) After 1994, the ADA began recommending individualized nutrition prescriptions: ◦ Metabolic profiles ◦ Treatment goals ◦ Willingness to change ◦ Predetermined calorie levels ◦ Macronutrient percentages (Mahan 2008) 4 5/10/2013 Principles of Nutrition and Dietary Recommendations for Individuals With Diabetes Mellitus Published in 1979 by the American Diabetes Association. Goal was to discourage the use of the preprinted, standardized “ADA diets,” and encourage individualized nutrition counseling. “Each diabetic person should have the opportunity to discuss reasons for the diet and to set diet goals with a professional diet counselor.” (Caughron 2002) Principles of Nutrition and Dietary Recommendations for Individuals With Diabetes Mellitus 1. Goals 2. Protein 3. Total Fat, Saturated Fat, and Cholesterol 4. Carbohydrates and Sweeteners 5. Fiber 6. Sodium 7. Alcohol 8. Micronutrients:Vitamins and Minerals (Caughron 2002) Carbohydrate Counting Also called “Carb Counting” A meal planning technique to help manage blood glucose levels. Carbohydrates raise blood glucose. By keeping track of how many carbohydrates to eat and setting a limit for the maximum amount to eat, carb counting can help to keep blood glucose levels in normal range. (American Diabetes Association 2013). 5 5/10/2013 Carbohydrate Counting Patients need to know: ◦ What foods have carbohydrates? ◦ ◦ ◦ ◦ How much carbohydrates can I have a day? At meals? At snacks? y g are in these foods? How manyy carbohydrates servings How do I read a nutrition label? Why is carbohydrate counting important? (American Diabetes Association 2013). Carbohydrate Counting Sources of Carbs: Grains Fruit & fruit juice Milk & yogurt Starchy vegetables Beans, peas, and soy products ◦ Sweets and snacks (American Diabetes Association 2013). How Much Carbs: ◦ Women: ◦ ◦ ◦ ◦ ◦ 45-60 grams/meal 15-30 grams/snack ◦ Men: 60-75 grams/meal 15-30 grams/snack An RD or CDE can determined the exact amount of carbohydrates you need based on your age, weight, gender, activity level, medications, and other health conditions. Carbohydrate Counting How much carbs is in this? ◦ 1 carb choice = 15 grams ◦ ◦ ◦ ◦ 1 slice of bread 1 piece of fruit ½ cup starchy vegetables 1/3 cup rice or pasta ◦ ½ cup oatmeal ◦ 2 small cookies ◦ 1 Tbsp sugar, jelly, honey (American Diabetes Association 2013). 6 5/10/2013 Nutrition Labels 1. Serving Size 2. Total Carbohydrates (g) ◦ Reading nutrition labels helps determine how many carb choices are in each serving ◦ ◦ ◦ ◦ 1 carb = 15 grams 2 carb = 30 grams 3 carb = 45 grams 4 carb = 60 grams ◦ 5 carb = 75 grams (American Diabetes Association 2013). MEDICAL NUTRITION THERAPY Medical Nutrition Therapy Medical Nutrition Therapy (MNT) ◦ is the term for the specific nutrition services provided to treat diseases and conditions. People at risk for diabetes and those with diabetes should receive individualized MNT to achieve treatment goals, preferably provided by a Registered Dietitian. (Mahan 2008) 7 5/10/2013 Medical Nutrition Therapy MNT includes: ◦ 1) Performing a comprehensive nutrition assessment determining the nutrition diagnosis. ◦ 2) Planning and implementing a nutrition intervention using evidence-based nutrition practice guidelines. ◦ 3) Monitoring and evaluating an individual’s progress over subsequent visits with the RD. RDs provide MNT and other nutrition services for a variety of diseases and conditions including: ◦ Type 1 Diabetes ◦ Type 2 Diabetes ◦ Gestational Diabetes (Mahan 2008) MNT for Preventing Diabetes “Decrease the risk for type 2 diabetes and cardiovascular disease by promoting healthy food choices and physical activity leading to moderate weight loss that is maintained.” (Mahan 2008) MNT for Managing Diabetes 1. To the extent possible, achieve and maintain: ◦ Blood glucose levels in the normal range or as close to normal as is safely possible. ◦ A lipid and lipoprotein profile that reduces the risk for vascular disease. ◦ Blood pressure levels that reduce the risk for vascular disease. 2. To prevent, or at least slow the rate of development of the chronic complications of diabetes by modifying nutrient intake and lifestyle as appropriate. (Mahan 2008) 8 5/10/2013 MNT for Managing Diabetes 3. To address individual nutrition needs, taking into account personal and cultural preferences and g g willingness to change. 4. To limit food choices based only on evidence and to maintain the pleasure of eating. (Mahan 2008) NUTRITION CARE PLAN Nutrition Care Plan Communicates the specific steps used to deliver MNT for diabetes. Can be used in individual and group sessions. Nutrition Care Plan: 1. Nutrition Assessment 2 Nutrition Diagnosis 2. 3. Nutrition Intervention 4. Nutrition Monitoring and Evaluation (Mahan 2008) 9 5/10/2013 Nutrition Care Plan 1. Nutrition Assessment ◦ Histories: nutrition, medical, social, and family ◦ Baseline for outcomes monitoring 2. Nutrition Diagnosis 3. Nutrition Interventions gy symptoms y p ( ) format ◦ Problem, etiology, (PES) ◦ ◦ ◦ ◦ ◦ Food and meal plan Behavioral changes Short-term and long-term goals Self-management training Educational topics covered and materials provided (Mahan 2008) Nutrition Care Plan 4. Nutrition Monitoring and Evaluation ◦ Registered Dietitian’s impressions related to patients acceptance and understanding ◦ Anticipated compliance ◦ Successful behavior changes ◦ Additional needed skills or information ◦ Additional recommendations ◦ Plan for ongoing care (Mahan 2008) Nutrition Care Plan: Interventions 1. Develop a Meal Plan ◦ Begin with modifying the patient’s usual intake as necessary, do p p NOT start with a set calorie or macronutrient prescription. Feasible for the patient? Appropriate for diabetes management? Encourage healthful eating? (Mahan 2008) 10 5/10/2013 Nutrition Care Plan: Interventions 2. Self-Management Training ◦ Purpose: identifying strategies for behavioral change that increase motivation and adherence to necessary lifestyle changes. ◦ Numerous meall planning N l i approaches h are available: il bl Diabetes nutrition guidelines Menu approaches Carbohydrate counting Exchange list ◦ No single meal planning approach has been shown to be more effective than any other. (Mahan 2008) Diabetes SelfSelf-Management Training Essential Self-Management Nutrition Education Skills: ◦ ◦ ◦ ◦ ◦ ◦ Sources of carbohydrates, protein, fat Understanding nutrition labels Modification of fat intake Use of blood glucose monitoring for problem solving Adjustments in carbohydrate intake or insulin for exercise Guidelines for eating out ◦ ◦ ◦ ◦ ◦ Alcohol consumption guidelines Snack choices Use of nonnutritive sweeteners Grocery shopping guidelines Vitamin, mineral and botanical supplements (Mahan 2008) Nutrition Care Plan: Interventions 3. Facilitating Behavioral Changes and Goal Setting ◦ Successful behavioral changes requires comprehensive education, skill development, and motivation. ◦ Different intervention strategies may be needed for patients in different stages of change process. Transtheoretical Model ◦ Goals should be: The patients priority Specific Realistic Written in behavioral language (Mahan 2008) 11 5/10/2013 CURRENT NUTRITION RECOMMENDATIONS FOR TYPE 2 DIABETES Registered Dietitian (RD) According to the American Association of Diabetes Educators and the Academy of Nutrition and Dietetics: ◦ “The team member with the most expertise and demonstrated effectiveness in fostering healthy eating for diabetes is the registered dietitian.” RD’s effectives has been documented in several studies: ◦ Decreases A1C: 1% in newly diagnosed type 1 diabetes 2% in newly diagnosed type 2 diabetes 1% in patients who have had type 2 diabetes for at least 4 years ◦ Reduction in use of health services and costs (Mensing 2011) Key Concepts to Address Key nutrition concepts to facilitate healthy eating: ◦ ◦ ◦ ◦ ◦ ◦ 1. Meal Planning 2. Grocery Shopping 3. Cooking 4. Food Labels 5. Modifying Recipes 6. Eating Out ◦ ◦ ◦ ◦ 7. Snacking 8. Travel 9. Alcohol 10. Parties/Special Events (Mahan 2008) 12 5/10/2013 Recommendations for Type 2 DM First Priority: ◦ Adopt lifestyle changes that improve: Metabolic abnormalities of blood glucose Dyslipidemia Hypertension Emphasize: ◦ ◦ ◦ ◦ Blood glucose control Improved food choices Increased physical activity Moderate calorie restriction rather than weight loss (Mahan 2008) Recommendations for Type 2 DM The key principle of diabetes nutrition recommendations is optimal nutrition through healthy food choices. A healthy meal plan includes the following: Multiple servings of fruits and vegetables, whole ggrains, legumes, g low-fat dairy foods, fish, lean meats, poultry, and healthy fats. (Mahan 2008) Choose My Plate Building Blocks for a Healthy Diet Focus on fruits Vary your veggies V i Make at least half your grains whole Go lean with protein Get your calciumrich foods (Choosemyplate.gov 2013) 13 5/10/2013 Recommendations for Type 2 DM Dietary References Intakes (DRIs) ◦ 45-65% of calories from carbohydrates ◦ 10-35% of calories from protein ◦ 20-35% of calories from fat (Mensing 2011) Carbohydrates and Glycemia What to focus on when counseling a patient: ◦ 1. sources of carbohydrates ◦ 2. recommended portion sizes ◦ 3. servings of carbohydrates per meal Totall amount off carbohydrate T b h d consumed d at meals, l regardless of the source (starch or sucrose) is the primary factor of postprandial glucose levels. Carbohydrate counting or the exchange system are two methods to monitor total grams of carbohydrates to achieve glycemic control. (Mensing 2011) Carbohydrates and Glycemia Consistency is key! ◦ Be consistent with the timing of meals and snacks. ◦ Be consistent with eating carbohydrates at every meall and d snack. k ◦ Be consistent with the total amount of carbohydrates consumed at meals. ◦ Be consistent with matching carbohydrate intake to insulin regimens. (Mensing 2011) 14 5/10/2013 Carbohydrates and Glycemia According to the American Association of Diabetes Educators, American Diabetes Association, and the Academy of Nutrition and Dietetics: y ◦ “Low-carbohydrate diets are not recommended for persons with diabetes- safety and efficacy for improved glycemia and weight loss are unproven. Foods containing carbohydrate are important components of a healthy eating pattern.” (Mensing 2011) Protein and Glycemia Encourage: ◦ ◦ ◦ ◦ Lean protein Protein low in saturated fat High in omega-3 fatty acids Follow recommended portion sizes Glucose produced from protein does not increase blood glucose concentrations. Ingestion of protein stimulates acute insulin secretion but does not have long-term effects on insulin requirements. (Mensing 2011) Fat and Glycemia Dietary fat is believed to alter the predicted postprandial response to a carbohydrate containing meal. Dietary fat D f is presumed d to slow l glucose l absorption b and d delay the peak glycemic response to ingestion of carbohydrate containing foods. However…dietary fat has minimal effects on decreasing postprandial glucose, altering insulin requirements, and slowing gastric emptying. (Mensing 2011) 15 5/10/2013 Fat and Glycemia Encourage: ◦ Reduced intake of saturated and trans fatty acids Butter, lard, bacon, sausage, poultry skin, baked goods, fried foods, doughnuts cookies doughnuts, cookies, etc. etc ◦ Replace with monounsaturated fats and omega-3 fatty acids Have beneficial effects on insulin action. Canola, olive, & peanut oil Most nuts Fish oil, salmon, mackerel, herring (Mensing 2011) Alcohol and Glycemia Moderate amounts of alcohol (less than 1 drink per day for women, less than 2 drinks per day for men) consumed with food has minimal effect, if any, of glucose and insulin concentrations. Type of alcohol consumed does not make a difference. 1 drink = 12 oz beer, 1.5 oz distilled spirits, 5 oz wine (Mensing 2011) Weight Management High incidence of overweight and obesity is a major challenge in diabetes care. Weight loss is an important goal for patients who are overweight or obese. Moderate weight loss of 5%-10% can improve glycemia. Moderate weight loss reduces the risk of developing cardiovascular disease by reducing blood pressure, improving lipids, and decreasing total cholesterol. Combine reduced energy intake, physical activity, and behavioral changes are the most effective strategies for weight loss and management. (Barclay, A. et al 2010) 16 5/10/2013 Nutrition Recommendations for Weight Management Most patients with type 2 diabetes are overweight and insulin-resistant. ◦ ALL educators should emphasize: Healthy Eating Reduction of calories, saturated and trans fat, cholesterol and sodium Weight W i h LLoss 500-1000 kcal/daily reduction in calories 1000-1200 kcal/day for women 1200-1600 kcal/day for men Physical Activity Modest and based on patient’s willingness and ability to change 30-45 minutes of moderate aerobic activity, 3-5 days a week (Klein, S. et al 2004) Weight Management Effective nutrition interventions for weight management: ◦ 1. individualized reduced energy diet ◦ 2. total caloric intake distributed evenlyy throughout g the dayy 4 to 5 meals/snacks per day, including breakfast ◦ 3. portion control emphasized ◦ 4. meal replacements for patients who struggle with food selection and/or portion control (Mensing 2011) Weight Management Weight loss is associated with: ◦ ◦ ◦ ◦ Energy deficit Diet adherence Enthusiasm of the counselor Improved behavioral strategies: Self-monitoring Stress management Stimulus control Problem solving Social support ◦ NOT- nutrient composition (Mensing 2011) 17 5/10/2013 IMPLEMENTING BEHAVIOR CHANGE Behavior Change The goal of behavior change is to produce positive outcomes. The patient’s goal should be a priority to the patient- not the educator’s perceived priority that the patient should have. Goals should be: specific, realistic, measureable, attainable, and a priority to the patient. (Mensing 2011) Behavior Change Transtheoretical Model of Behavior Change Precontemplation Contemplation Preparation Action Maintenance Nutrition interventions need to match the patient’s stage of behavior change to support healthy eating. A behavior change is something a patient can work on that will influence their blood glucose or weight. Educators: Focus on behavior change not the outcome. (Mensing 2011) 18 5/10/2013 Behavior Change Goal Setting Considerations: ◦ ◦ ◦ ◦ ◦ ◦ ◦ ◦ ◦ 1. Educator and patient mutually set goals 2. Respect each patient as an individual 3. Patient investment 4. Remember the patient’s patient s agenda 5. Individualize the goals 6. Focus on the behavior not the outcome 7. Create a written agreement 8. Include family and friends for support 9. Keep in mind cultural and financial considerations Behavior Change Goals Example Behavior Change Goals Immediate Outcome: ◦ Goal is learning Intermediate Outcome: ◦ Goal is behavior change Post-Intermediate Outcome: ◦ Goal is clinical improvement Long-Term Outcome: ◦ Goal is improvement in health status and cost savings. 1. I will measure my food and beverages for 3 days and record the amounts. 2. I will check my blood glucose 2 hours after each meal every day for the next 3 days. 3. I will substitute sweet tea for unsweet tea with a sugar substitute. 4. I will not skip my breakfast meal for the next 7 days. 5. I will portion out my carbohydrate snacks to assist with portion control.

FACT: The main risk factors for type 2 diabetes are: ◦ diet high in calories ◦ being overweight ◦ inactive lifestyle TIP: If you have diabetes you should watch your intake of carbohydrates, including sugar. (Steyn, NP. 2004) 20 5/10/2013 Skipping Meals Can Help Me Lose Weight FACT: If you skip a meal, your body will think that you are in starvation mode and therefore slow down your metabolism to compensate.You then tend to overeat at the next meal. FACT: Often, Often skipping a meal and then eating too much at the next meal means that you have a higher total caloric intake than if you just ate more frequently throughout the day. TIP: A better approach is to eat smaller frequent healthy meals and snacks to keep your blood sugar balanced. (Mahan 2008) Certain Foods, like Grapefruit, Celery, Vinegar, or Cabbage Soup, Can Burn Fat and Make You Lose Weight. Fact: No foods can burn fat. Some foods with caffeine may speed up your metabolism (the way your body uses energy, or calories) for a short time, but they do not cause weight loss. Tip:The best way to lose weight is to cut back on the number of calories you eat and be more physically active. (Mahan 2008) Fruit has Too Much Sugar FACT: Fruit is a healthy choice. It's true that fruit has naturally occurring sugar, but it is also full of vitamins, minerals and fiber that are important for good health health. TIP: Choosing more vegetables and fruit, naturally sweetened by Mother Nature can help you maintain your weight and reduce your risk of developing chronic diseases. (Mahan 2008) 21 5/10/2013 Avoid Carbohydrates to Lose Weight FACT: Many low-carb diets actually do not provide sufficient carbohydrates to your body for daily maintenance. Therefore, your body will begin to burn stored carbohydrates (glycogen) for energy. When your body starts burning glycogen, water is released. The drastic initial drop of weight at the beginning of a low-carb diet is mostly the water that you lose as a result of burning glycogen. FACT: The truth is that low-carb diets are also often calorierestricted! Followers only eat an average of 1000 - 1400 calories daily, compared to an average intake of 1800 - 2200 calories for most people. ◦ To lose one pound a week, you only need to eat 500 fewer calories per day in your normal diet. TIP:Therefore, it doesn't matter if you eat a high- or lowcarb diet, you will lose weight if you decrease your calorie intake to less than needed to maintain your weight. (Mahan 2008) Don’t Eat Anything White FACT: Foods that contain white flour and white sugar do typically contain more calories and carbohydrates. However, they can be part of any healthy diet when eaten in moderation. TIP: Make sure to eat white foods like low-fat milk, yogurt, potatoes, mushrooms, cauliflower, and rice. (Mahan 2008) Dietitians Never Eat Junk FACT: Dietitians eat all sorts of different foods, even chocolate, french fries, chips and candy...on occasion. FACT: Dietitians believe that healthy foods are delicious foods. FACT: And we also believe that there's nothing wrong with the occasional treat. 22 5/10/2013 Questions “As we say in the American Institute of Wine and Food, small helpings, no seco s.
