- Choose foods lower in fat
- However, over emphasis on fat-free at the expense of excessive Carbohydrates results in weight gain
- Do not trade fat for high Carbohydrate, increased calorie meals
- Monounsaturated fats (e.g. olive oil) are a part of a Healthy Diet
- Recommendations
- Replace fatty foods
- Eat fruits, vegetables, grains and beans
- Eat smaller portions
- Select non-fat/low-fat milk and dairy products (and overall limit to 1-2 servings per day)
- When eating prepared foods, choose lower saturated fat
- However, over emphasis on fat-free at the expense of excessive Carbohydrates results in weight gain
- Limit consumption of meats (especially high fat meat)
- Recommendations: 1 serving of meat per day
- Lean meat (2-3 ounces)
- Poultry (2-3 ounces)
- Fish (2-3 ounces)
- General
- Select lean cuts, and smaller portions of meat
- Choose beans, seafood and poultry
- Instead OF beef, pork and lamb
- Select baked and broiled meats
- Instead of fried, charcoal-broiled, or smoked

VI. Guideline: Healthy Eating Plate (Harvard, modified version of ChooseMyPlate.org)
- Key Components
- Limited items
- Limit butter, saturated fats and avoid trans fats
- Use healthy oils (e.g. olive oil, canola oil)
- Small handful of nuts
- Limit milk/dairy (1-2/day), juice (1/day) and avoid sugar drinks (e.g. soda)
- Limit salt
- Limit to 2300 mg/day (1 tsp), and some guidelines recommend 1500 mg/day (2/3 tsp)
- Limit butter, saturated fats and avoid trans fats
- References
- Harvard Nutrition Source
VII. Guideline: USDA Standard Food Pyramid for Adults (replaced by other meal planning strategies)
- Precautions
- Consider the Healthy Eating Plate above as an alternative
- USDA Food Pyramid is influenced by many outside forces including the meat and dairy industry
- Based on Scientific Report of Dietary Guidelines Advisory Committee, released every 5 years
- However, USDA breaks with advisory board when in political conflict (e.g. meat/dairy, environment)
-
Fiber: 6 to 11 servings per day (5 to 10 oz grains per day)
- Bread
- Cereal
- Rice or Pasta
- Vegetables: 3-5 servings/day (2 to 4 cups/day)
- Fruits: 2-4 servings/day (1.5 to 2.5 cups/day)
- Dairy: 2 to 3 servings per day (3 cups/day)
- Milk
- Yogurt
- Cheese
-
Protein: 2-3 servings per day (5-7 oz/day)
- Meat
- Poultry
- Fish
- Dry beans
- Eggs
- Nuts
- Fats, oils, and sweets (22 to 44 g/day, up to 36 g/day in age over 60 years)
- Used only sparingly
- Snacks (Discretionary Calories)
- Limit to <10 to 15% of total calories, or <100 to 440 kcals/day (up to 350 kcals/day in over age 60 years)
VIII. Guideline: Miscellaneous
- Be physically active and maintain a healthy weight
- Moderate activity for 30 minutes on most days
- Maintain a body weight within 20% of ideal
- Limit Alcoholic beverages
- Alcohol, when used in moderation may be a part of a healthy lifestyle
- However, encouraging Alcohol use in those who use little to no Alcohol, risks Alcohol Abuse
- Those who safely use Alcohol in moderation may continue
- Risks associated with longterm heavy Alcohol use or abuse
- Oropharyngeal cancer
- Esophageal Cancer
- Hepatocellular Carcinoma
- Breast Cancer
- Alcohol, when used in moderation may be a part of a healthy lifestyle
IX. Approach: Pearls
- Avoid products that raise the risk of excess calories, weight gain, Diabetes Mellitus
- Avoid sugar-containing soft drinks
- Cereal grains (wheat, rye, barley, corn, rice, oats, millet) and pseudo-grains (quinoa, amaranth)
- Whole grains are preferred
- Whole grains mill all three grain components (bran, germ, endosperm) together
- Refined grains contain only the milled endosperm (germ and bran are removed)
- Wet grains are preferred over dried grains (from a nutritional, excess calorie standpoint)
- Cooked oatmeal is more filling initially than dried cereals
- Whole grains are preferred
-
Dietary Fat
- Use healthier oils high in monounsaturated fat (olive oil, saflower oil, canola oil, peanut oil)
- Avoid unhealthy, tropical oils (coconut oil, palm oil) that are 86-92% saturated fat
- Decrease in saturated fat and trans fat lowers coronary risk
- Unsaturated fats in moderation are considered a part of a Healthy Diet
- Over emphasis on fat-free at the expense of excessive Carbohydrates results in weight gain
- Replacing unsaturated Dietary Fat with refined starch and sugar results in worse outcomes
- Use healthier oils high in monounsaturated fat (olive oil, saflower oil, canola oil, peanut oil)
- Dairy
- Plant-based food focus (plant forward)
- See Plant Based Diet
- Encourage superfoods
- Eat less meat (esp. less red meat)
- Replace red meat with nuts, legumes, fish and poultry
- Avoid highly processed meats such as deli slices (increased cancer risk)
- High Temperature cooking (e.g. barbeque, open flame) of meat or poultry is associated with Diabetes risk
- Logistics and social factors
- For those who have too little time to practice a healthy lifestyle (but avoid preaching)
- If you do not have time to be sick, you must take time to be well
- Healthier dietary change is superior to medications in its effect on morbidity and mortality
- Consider this as disease modifying nutrition
- Implement dietary changes in steps (e.g. one per clinic visit)
- At each step, replace one less Healthy Dietary item with a more healthy item of the patient's choice
- Have patients choose one healthy item from a superfoods list
- In the longterm, diet improves by "crowding out" the less healthy choices
- Make media-free, family dinners a habit
- Set out a plate of cut vegetables for snacking while preparing dinner
- Have lunch containers open to prepare at same time while making dinner
- Many of the dinner items can be placed directly into lunch containers
- Make time to eat breakfast (high quality with fiber and nutrients)
- Breakfast skipping increases the risk of Type 2 Diabetes Mellitus, Obesity, Coronary Disease
- Bi (2015) Public Health Nutr 18(16):3013-9 +PMID:25686619 [PubMed]
- For those who have too little time to practice a healthy lifestyle (but avoid preaching)
- Produce shopping and storage
- Buy max of only 2 weeks of perishables, wash, trim and store in humidified refrigerator door
- Choose recipes in advance of shopping and stick to a shopping list
- Choose recipes that share core ingredients, may be prepped in advance, and good as left-overs
- Keep salad greens and herbs wrapped in damp towel or in a container with water at bottom
- Roast left over vegetables at the end of each week
X. Approach: Public Health and Prevention
- Healthy Lifestyle is the keystone to reversing a U.S. trend of worsening overall health despite medical advances
- Maximal medical management for cardiovascular disease has reached a mortality plateau (2010)
- Further advances in lowering cardiovascular mortality will need to maximize healthy lifestyle
- "Greatest advances... offset by the burden... caused by too many people eating too much... moving too little"
- (2005) Institute of Medicine +PMID:22379642
- Maximal medical management for cardiovascular disease has reached a mortality plateau (2010)
- Children are not compelled to relive their parent's medical history ("genes are not destiny")
- High genetic risk patients with healthy lifestyle lowered their coronary event risk by 46%
- Since 1994, Obesity (BMI>30 kg/m2) has dramatically increased throughout the U.S
- As of 2015, most U.S. states have more than 26% Obesity rates (contrast with <14-18% in 1994)
- As of 2014, Type II Diabetes MellitusPrevalence in the U.S. has increased to 22% (contrast with 5% in 1980)
- Up to 60% of U.S, toddlers in 2017 are projected to be obese by age 35 years old
- Food insecurity and hunger
- Associated with increased hospitalizations and worse comorbidity management
- Most plant-based meals can be prepared for $1-3 per serving
-
Protein importance in the diet is over-stated at the expense of health, cost and the environment
- In the U.S., even those on plant based diets far exceed Protein requirements (0.8 g/kg or 40-60 g/day)
- Agriculture (esp. live stock) is the world's second largest emitter of greenhouse gases (behind energy)
- LIvestock are heavy resource utilizers (food, water); the same resources could support far more people directly
XI. Approach: Restaurants - Menus of Change (Harvard, Culinary Institute of America)
- Regionally sourced foods
- Intact whole grains (minimal processing), nuts and legumes
- Healthier oils (olive oil, saflower oil, canola oil, peanut oil)
- Decrease the sugar and salt
- Prepare more home meals (less eating-out at restaurants)
- Plant-based food focus (plant forward)
- "Delicious, unapologetic, cravable" recipes making use of mediterranean, asian and latin flavors
- Maximize the use of local produce
- Meat in smaller amounts (2 ounce), less frequently overall (Protein-flip: meat becomes the side-dish)
- More seafood (diverse selection) than poultry/eggs than red meat
- Replace red meat with nuts, legumes, fish and poultry
- Blended burgers (meat mixed with mushrooms, grains, vegetables, legumes)
- Meat becomes the dish condiment or seasoning
- More seafood (diverse selection) than poultry/eggs than red meat
- Resources
- Menus of Change
- Plant Forward 50 (chefs and restaurants)
XII. Approach: Teaching Kitchens
- Many health care organizations, teaching institutions and communities have built teaching kitchens
- Offers hands-on education for delicious, healthy meal preparation for sustained habits
- Minimal home kitchen kit
- Chef knife, pairing knife, cutting board, vegetable peeler, can opener
- Measuring spoons and cups, whisk, slotted spoon, colander/strainer, mixing bowls
- Stock pot with lid (5 qt)
- Saute pan (11")
- Sheet pan and cooling rack
- Minimal home pantry
- Flour (whole wheat, unbleached all-purpose), Brown rice, rolled oats, grains (e.g. quinoa), whole wheat pasta
- Nuts (e.g. almonds), dried fruit (e.g. raisins), dried beans (e.g. lentils, black beans, split peas)
- Oils (olive, canola), Vinegar (wine, rice or apple), mustard, honey
- Kosher salt, black pepper
- Flavor foods by cuisine
- Workspace organization ("Mise en Place")
- Back row
- Tray for ingredients and prep bowls
- Large scrap bowl (and consider bags for freezing stock)
- Front row
- Cutting board, knives, spices/oils
- Back row
