Theory of Planned Behavior/Reasoned action
-behavioral change is based on motivation (intention) and ability (behavioral control); based on behavioral intention (motivation behind making a change=biggest driver of change) -6 constructs represent one's actual control over behavior 1. attitude (re: risks/benefits/control) 2. behavioral intention (motivation) 3. subjective norms (perception of other's opinion re: behavior) 4. social norms (actual behavior of a group/customs of a group) 5. perceived power 6. perceived behavioral control
circadian rhythm outputs
-behavioral/physiological consequences of operators -sleep -performance: alertness, kinetic activity, motor skills (precision), strength/stamina -food seeking behaviors (quantity and quality)
Cognitive Behavioral Theory
-best for preparation, action, maintenance stages -helps with problem solving basic principles: -recognize and reframe non-productive thinking (all or nothing, catastrophizing, discounting the positive, overgeneralizing, mind reading, fortune telling, "should" or "must" statements) -be aware of underlying beliefs/emotions -reframe self talk by working through ABCD of behavioral change A: what Action or event occurred? B: what Beliefs do you have about what occurred? C: what are the emotional Consequences of those beliefs? D: how can you Dispute the beliefs that are unhealthy or Distorted?

-body's rxn/response to modified inputs -core body temp -melatonin secretion -cortisol secretion and timing of spike -cutaneous blood flow
Mindfulness Research
-brain can grown 700 new neurons/day -brain restructures based on thoughts, attitudes, emotions -conscious thought can re-train brain through activating self awareness (extended and momentary separately) -8 wks mindfulness = increase L prefrontal cortex (planning, personality, happiness); increase gray matter in hippocampus, reduce gray matter amygdala (emotion/stress/depression) -strengthen pre-frontal cortex-->amygdala connection (problem solve and modulate emotions)
Food and sleep
-breakfast: none, late, low-carb=decreased cortisol spike; early breakfast helps shift wake-up time earlier -dinner: increased carbs (or late diinner) delays sleep
Stress Screening
-brief discussion re: stress recommended for all pts -stress mgmt plans help prevent/trx stress -work stress + HD, T2DM -perceived stress scale (cohen, 1983)-10 ?'s
Macrocitic Anemia and Plant Sources
-caused by B12, B9/folate or homocysteine deficiency (rare in WFPD) -CBC w/ diff -vita B12 (cobalamin)--only made by bacteria; fix=fortified foods (milk) or supplements (water soluble, no OD concern) -B9/folate: plants ~ dark leafy greens, cruciferous vegetables, peas -elevated homocysteine is ass'd with CVD but adds little to other biomarkers (lipids, CRP); no added value to get homocysteine levels for CVD risk profiling
Smoking death stats
-causes 1/5 deaths in US -tobacco products kill 1/2 people who use them -smoking=87% lung CA deaths, 32% CVD deaths, 80% COPD deaths -ARR for CA=30%
Circadian Rhythm
-central + peripheral oscillators -central = suprachiasmic nucleus -peripheral =all major organs to allow synchronization w/ centrsl -sleep propensity: ability to transition to sleep or stay asleep
Suprachiasmic Nucleus (SCN)
-central clock -part of hypothalamus -regulates melatonin -nerves from SCN directly innervate other tissues -input nerves=from retina to entrain central oscillators -output nerves=to pineal gland for melatonin secretion -output splanchnic nerves=to ANS/adrenal glands-->NE/epi/glucocorticoids/aldosterone to regulate blood flow, T, food intake
Micronutrients
-chemical elements essential in small amounts for growth and health (vitamins/minterals) -beneficial non-nutrients: good but not essential for life (antioxidants (decrease inflam), anti-inflam, phytochemicals, support immune system, etc) -supplements not required to get micronutrient balance, better from whole food -normally: antioxidant, improve cell health, anti-inflam -balance is key: too much or too little is bad -prescription: specific foods that tend to contain specific micronutrients; don't prescribe specific micronutrients
Nutrient deficiency and mood
-child-bearing age F: folate, B12, Ca, Fe, selenium, zinc, omega 3's ass'd w/ depression; folate deficiency decreased med. efficacy -fish oil and folic acid (+/- omega 3's in pregnant women and bipolar) supplements for depression trx -fried foods, refined grains, sugar associated w/ depression/anxiety -fast food frequently = 40% increased risk for depression -dose-response relationship bw fat type and depression (trans-fats + depression, mono-poly unsat fats - depression)

Providers and advocacy
-contribute to public health (provide info to organizations) -provide credibility -lend a powerful voice -not much mass appeal, but can serve as champions for special causes and talk to the media (not like a celebrity) -should not leverage network of providers d/t contracts
High Micronutrient Food Families
-cruciferous vegetables (broccoli, cauliflower, cabbage): 1c/day -dark green leafies (spinach, chard, kale, arugula, loose leafy lettuce): 2 c/day -alliaceous veggies (onions, garlic, leeks): 1/2 c/day -carotenoid veggies (carrots, beets, yams): 1/2 c/day -other vegetables (tomato, celery, squash, peppers, cucumbers, eggplant): 1 c/day -dark berries (cherries, pom, blue, etc): 1/2 c/day -other fruit (apples, pears, melons, citrus, stone, tropical): 3 c/day
Circadian rhythm on sleep physiology
-darkenss + melatonin -->vasodilation-->warm extremities/cool core body-->sleep -continued patter x 4 hrs sleep (slow wave)-->decresed BP/sympathetic tone -during sleep=DNA repair, leptin secretion (controls appetite), increased cortisol, FA metabolism -late sleep: decreased melatonin-->cooling extremities and increased core temp-->longer REM-->increased BP, sympathetic tone/baroreceptor sensitivity -awakening: cortisol spike
Physical activity as a vital sign
-days per week * min per day = minutes per week -incorporate PA guidelines (cardio and strength) + balance/flexibility

Restless Leg Syndrome (RLS)
-sensation of urge to move legs -worse in evenings -movement helps w/ symptoms -sx's not d/t other medical issue -prevalence: 5-15% gen po
American Nutrition Shortfalls
-shortfall nutrient=one under-consumed by 25% of US population -Calcium (dairy, seeds, tofu, almonds, beans, dark greens) -Fiber (only in plant foods, supports microbiome) -Mg (brazil nuts, edamame, dark chocolate) -K (potatoes, avocados, soybeans, plantains) -Vita A (sw potatoes, liver, spinach, canteloup, black eyed peas) -Vita C (bok choy, broccoli, brussels, citrus) -Vita D (high fat fish, dairy; SUNLIGHT>DIET for Vita D) -Vita E (sunflower seeds, almonds, hazelnuts) -Vita K (oils, dark leafy greens, brussels)
Fat
-should be 15-30% total calorie intake -Polyunsaturated -monounsaturated -saturated -trans -prescription: don't count fat grams, instead prescribe types of food ex: cheese/pizza -normally a negative prescription
Flexibility Assessment Tests
-sit and reach (hamstrings and low back); don't use w/ low back pain pts -hamstring flexibility may be related to decreased risk of falls and/or decreased low back pain -can compare to age/peers/gender
Body Composition Assessment Tests
-skin fold caliper testing: subq fat is proportional to the total mt of body fat (~1/3 of the body); w/in 3.5% accuracy; test abdomen, tricep, bicep, chest/pectoral, medial calf, midaxillary, subscapular, spurailiac, thigh; normal ranges: M-10-22% and F-20-32% -Densitometry: estimates body fat % based on body mass:volume ratio (underwater weighing, DEXA, mulitcompartment) -bioimpedence test is related to hydration status and often incorrect; not recommended
Exercise Intensity Assessment Tools
-talk test: able to talk and sing=light; able to talk, not sing=mod; neither=vigorous -respiratory rate: breaths per minute (best indicator of perceived exertion) -Perceived exertion (Borg scale): 1-10 (<3=light, 3-4=mod, >=5=hard) -Heart rate reserve (HRR)=ACSM recomendations (40-85% HRR) -max HR: <64%=low intensity, 64-76=moderate, >76=vigorous -METs: <3=light, 3-6=mod, >6=vigorous
Short Physical Performance Battery (SPPB)
-test for disability to predict mobility -includes: gait speed test, balance test, chair rise test -structured exercise can improve this score, prevent physicial decline, allow people to remain independent for longer (18% reduction in physical disability)
Physical Activity Vital Sign
-the aspect of total daily energy expenditure which pt's have the most control (others: rest, thermic effect from food) -2-item vital sign: 1. days/wk for mod-strenuous exercise (brisk walk) 2. min/day at this level? -Strength training must be asked separately (days/week)
T2DM
-the dz most influenced by body weight -BMI > 30=7x risk of T2DM in men and 12x risk in women -fat cells (esp abdominal) secrete inflammatory hormones-->cell dysfx and insulin resistance; alter carb/fat metabolism-->high BS
Action Plan
-the lifestyle prescription adjusted for the patient's ability, readiness and confidence -ex: start walking 5 min/day and increase to 150 min/wk (the original prescription) -should be written down and reviewed w/ patient -create during preparation phase of change
Positive Psychology
-the scientific study of strengths and virtues that enable individuals and communities to thrive (focus on happiness, but not lessen misery) -components: (PERMA) positive emotions (optimisitic), engagement (mindfulness), relationships (emotional and physicial connections), meaning (purpose in life), accomplishments (ambition) -not a trx -ex: count blessings, find and improve strengths, gratitude, kindness, etc)
Lifestyle Medicine Definition
-the use of lifestyle interventions in the treatment and management of dz -aim: replace medication with lifestyle changes -elements: whole food, plant-based, physical activity, adequate sleep, stress mgmt, avoidance of risky substances -collaborative model with patient -evidenced based -applies to every patient, every practice
Preventive Medicine
-traditional medical approach to prevent health conditions -immunizations, mammography, etc -focus in pubic health and population health
Muscle Strength Assessment Tests
-use weights (bench or squat press) -find their max load (lbs for 1 rep only) -refer to gym
Complementary and Alternative Medicine (CAM)
-used in addition or instead of standard trx -practices are not currently considered part of conventional medicine (not evidenced-based) -may use supplements, spiritual healing -typically not strong in science
Root Cause Analysis
-used to see what went wrong, or what caused a near miss -use 5 why's -cause and effect/fishbone dx -analyze -implement PDSA cycles
Bioelectrical Impedance Analysis
-uses small electrical signal to measure water w/in someone's body to determine body composition (fat:muscle) -more accurate for body fat% than BMI (better assumption of nutritional status) -recs: M <25%, F<32%
Tobacco Cessation Med Combos
-varenicline + bupropion=71% smoke free at 12 wks, 58% at 6 mo -bupropion + NRT=54% at 8 wks (50% w/ lozenge only)
Supplemental Melatonin
-varies individually -good for jetlag and circadian rhythm disorders -1-6mg=typical dose (possible cyp-450 interactions) -no endogenous suppression evidence now -SL=better bioavailability -sustained formulas=good for westward jetlag (increases morning drowsiness)
LM H&P
-vital signs (PA, diet, stress, sleep, emotional well-being, tobacco use, alcohol, BMI)-not standards, just a check-in -risk fx assessment (CVD, pre-DM, T2DM) -physical exam (waist, WHR, BIA, pulse, BP) -lab work and interpretation (CMP14, CBC, lipids, hsCRP, FSG, A1c, insulin, c-peptide, vita D, B12, TSH) -dx and mgmt -collaborative care and referrals
LM PE
-waist circumference (increased=increased risk for T2DM, HTN, CVD); M>=40" F>=35" -waist:hip ratio: normal M<=0.90 F<=0.85 -Bio-impedance analysis (BIA): body fat chart comparisons -pulse (may be elevated 2/2 physical deconditioning, alcohol, caffeine) -BP: normal <120/<80, elevated 120-129/<80, stage 1: 130-139/80-89, stage 2: >140/>90 (increases morbidity/mortality 2/2 HD, stroke, MI, AAA, etc)
Weight and lifestyle choice relationship
-weight is ass'd with: shorter sleep duration, increased stress, smoking cessation (< 10lbs, more in women; lose weight after quit smoking complete)
Best LM interventions for HTN
-weight loss (1mmHg decrease/1kg lost) -diet (DASH: fruits/vegs, whole grains, low fat dairy, reduced sat and total fat)=-11 mmHg -decrease dietary Na: <1500mg/d=-5mmHg -increase dietary K: 3500-5000mg/d=-5mmHg -exercise: aerobic=-7mmHg, dynamic resistance=-4mmHg, isometric resistance=-5mmHg -alcohol moderation=<2/d M <1/d F=-4mmHg
PA guidelines for weight control
-weight maintenance: >250 min/we mod; 60-90 min/day mod; strength/resistance 2/wk (less helpful than cardio) -weight loss: using PA alone for weight loss improves DBP, TG, fasting glucose, and CVD risk but little reduction in weight-requires caloric control as well -diet=weight loss; PA=weight maintenance
Planning advocacy
1-observe community of interest to determine needs 2-define advocacy goals and how you can best contribute 3. consider: -can an individual/group make a request to the decision makers? -are there other guidelines to consider? -is there an opportunity for public comment?
Levels of Processed Food
1-slightly (smashed or cut but nothing removed) 2-moderate (some content removed and/or added ingredients available in typical kitchen) 3-ultra (added ingredients not found in normal kitchen; chemicals) 80% whole or slightly processed <5% ultra
LM elements
1-whole food, plant based diet 2-physical actvity 3-stress mgmt/emotional wellness 4-sleep 5-smoking cessation/avoid risky substance abuse 6-positive psychology and connectedness
Mindful Weight Loss Approach
1. Am I physically hungry? (do you need a meal?) 2. How do I feel about my dietary choices so far today? (occasional treats are important) 3. Is it worth it? (no=use strategies to address what is triggering the craving and write in craving diary) If yes to the above... 4. How much of do I need to feel satisfied? -- savor without distractions or judgement Mindful Eating=listening to your body over intellectual decisions (good vs bad foods, etc)
ACSM 3 stages of exercise:
1. Initial (1-6 wks): mod intensity aerobic at 40-60% HRR in intervals; 15 min progress to 30 min 3-4/wk; goal: minimize soreness, injury and prepare for more exercise 2. Improvement (4-8 mo): duration increased <=20% weekly until 20-30 min vigorous; intensity max=5% increase in HRR q 6 session HRR=max HR - resting HR 3. Maintenance (forever): starts when pt reaches fitness goals (50th % for all fitness parameters)
10 steps to organize mind for patient assistance
1. ability to cross 3 dimensions: Focus, awareness, content 2. Agility to transition from one brain state to others (awareness, imagining, evaluating, collaboration, etc) 3. brain energy (+ through emotional and physical energy) 4. no frenzy before pt encounter (name it, non-judgementally acknowledge it, elicit + emotions) 5. prepare (clear mind) 6. connect (+ vagal tone) 7. focus attention (improve sleep) 8. no distractions 9. brain breaks (not possible with media exposure) 10. be creative (non-linear, divergent thinking) 11. be strategic
Exercise Pre-participation screening algorithm
1. asx and currently does or does not exercise: no clearance, progress slowly 2. asx w/ known CV, metabolic or renal dz: if currently exercising, no clearance for mod or slow progression to vig if cleared in past 12mo; not currently exercising=med clearance, start light 3. symptomatic: d/c exercise and get clearance; progress slowly
Motivational Interviewing
1. express empathy (normalize feelings, open ended ?'s; support autonomy) 2. develop discrepancy (highlight inconsistencies, support change talk) 3. roll with resistance (back off and reflect, empathy, ask permission to provide info) 4. support self-efficacy (identify successes, offer options for small changes) best in pre- and contemplation stages supports self-efficacy, self-motivation, self-confidence
LM Coaching process
1. help pt develop awareness of issue through reflections (simple, amplified, double-sided, or shifted-focus) 2. finding stage-matched intervention (educated for precont, action plan for prep, problem solve in action, reinforce + behavior in maintenance, problem solve and refarme in relapse)
Mindfulness Attitudes
1. non-judging 2. non-striving (relaxing) 3. acknowledge > acceptance 4. patience 5. self-reliance 6. beginners mind (open and unafraid)
Evidence for pt-physician interventions to influence health outcomes
1. physician elicits and encourages input from pt (activating the pt) 2. provider more emotionally engaged; matching pt's personality, give more info ahead of time 3. combo of activating pt and enhancing provider approach (1 and 2) -health outcomes were + affected in 44% of encounters where these were employed; improved collaboration
Maintenance of an action plan
1. reiterate provider's role 2. review dx and lifestyle recommendations 3. review action plan from last visit (successes and challenges) 4. summarize pt experience 5. positive psych to compliment any progress 6. ask: benefits gained, lessons learned, overall feeling about situation? 7. set new goal 8. summarize new goals with new action plans
Daily Total Energy Expenditure
1. resting energy: 60-75% total (mainly muscle protein breakdown/synthesis)=burns 5-6 calories/lb muscle/day in untrained muscle; if trained muscle=9 calories/lb/day 2. PA: 15->30% (only controllable caloric burning area) 3. Thermic effect from food: 10% -10% weight loss-->20-25% total energy expenditure decrease (non-resting decreases 30%, skeletal work increases 20%, 24 hr expenditure decreases 20%)
Responsibilities of LM Physicians
1. screen for lifestyle risk fx's and dz's 2. trx chronic dz with prescription of lifestyle changes 3. work w/ multidisciplinary team (refer out when needed) 4. ensure pt understanding of lifestyle influences 5. coach behavior change based on readiness to change
80% all premature deaths are attributable to:
1. tobacco use 2. poor diet 3. lack of physical activity
LM trx intensity
2 components: 1. intensity of contact hours 2. extent of lifestyle changes made ITLC maximizes both of these
Secondary insomnia
2/2: meds, peripheral hypoperfusion/vasospasm, visual impairment (opacification, retinal degeneration), RAAS issue (fluid imbalance)
Dr. Ludwig Johns Hopkins 2005 NEJM study
2000=first generation to have decreased life expectancy than prior generation
Red Meat Consumption and Mortality Study

Tobacco Cessation Meds
5 NRT: directly stimulate nicotinic receptors in ventral tegmental brain-->dopamine release -patch alone=15% more effective than placebo at 8 wks (45% tobacco free) -lozenge alone=10% more effective (40% at 8 wks) -<10 cig/day = no NRT benefit 2 non-nicotine meds: -Varenicline (chantix): partial nicotine receptor agonist (prevents w/drawals and reduces nicotine highs) -most effective monotherapy (30% more effective than placebo, 51% smoke-free at 12 wks, 35% at 6 mo) -pregnancy: C -12 weeks (+ 12 weeks=6 mo max) -Bupropion SR (Zyban): NE and dopa reuptake inhibitor - 10% more effective (40% at 8 wks) -? less weight gain -CI bipolar -pregnancy: C -6 mo max Off-label: clonidine, nortriptyline
METs
=metabolic equivalents (ratio of metabolic rate exercise: resting) -metabolic rate=amt O2 consumed -rest=1 MET sleeping: 0.9 walking=3 climbing stairs=5 running=18 -MET hrs/wk=MET/hr * hrs/wk -max benefit=10-20 MET hours/wk but min of standing x 2 hrs/day reduces mortality -no max recommendation-any increase = benefits, but benefit size decreases the higher you go
Nutrition Assessment
A: anthropometric data (weight, height, WHR, BMI, waist circumference, BIA-bioimpedance-helps est fat) B: biochemical data (lab work: Na, K, Hgb, Hct, glucose, a1c, albumin, TC, LDL, HDL, TG; vita D, B12, Fe, Ferritin) C: clinical assessment (age, gender, med hx, surg hx, activity level, nutritional hx (weight loss hx), absorption issues, vitals, PE) D: dietary assessment (current intake: solids/liquids; 24 hr recall and 3 day food record, mini nutritional assessment for the elderly >65 yo, behavioral motivators) -include religious, financial, emotional assessment as well -utilize RDs
Protein
Animal: -most concentrated (chx>beef>fish) -readily digestible -more sulfur-containing amino acids-->require buffering and can deplete Ca Plant: -soy, tofu, lentils, pinto beans, hempseed, whole wheat bagel, pumpkin seeds -less digestible -contain all essential amino acids, just not ideal proportion (combine them) --Legumes= best source of whole food, plant based protein (1.5cups = 22 grams of protein daily & recommended as a routine dietary goal for healthy adults) -rarely require prescription except elderly (poor absorption so require 25% more protein >70 yo), children, athletes -should be 15% calorie intake -broccoli>hamburger -soybeans=chx -weight loss=1.2-1.5g/kg (90-120g/day) -maintenance=0.7-1g/kg -higher protein intake increases thermogenesis and satiety
ABCD's of nutrition assessment
Anthropometric (height/weight, BMI, waist circ) Biochemical (labs) Clinical (vitals, PMH, PE-hair, nails, muscles) Dietary Intake (24 hr recall, 3-day record, food frequency questionnaire)

Ask about smoking at each visit Advise patients regularly to stop smoking using a clear, strong, personalized message Assess patient readiness to quit Assist patients to set stop dates, meds, and provide educational materials for self-help Arrange for follow-up visits to monitor and support patient progress. Time constraint: Ask, advise, refer
5 A's
Assess: health risks Advise: changes (clear and specific) Agree: focus and pt's interest in change Assist: setting and achieving goals Arrange: regular f/u and support -5 A's are proven to improve motivation; patient centered instead of expert centered -goal: brief health behavior counseling using COLLABORATIVE approach to improve internal motivation -counseling /=advice 5 A's of Tobacco Cessation: Ask (about tobacco use), Advise (strong advice to quit), Assess (stage of change), Assist (through counseling, meds, etc if ready to quit), Arrange (f/u)
5 A's for physical activity
Assess: is the pt exercising; how do you feel about exercise? Advise: specific info about health benefits matched to stage of change; tailor advice to pt's problems and comorbidities Agree: goals and a prescription Assist: goal setting, social support, self monitoring, brainstorming ideas to fit exercise into daily life; relapse prevention Arrange: f/u session and interim support, and referrals if necessary

Steps to making an action plan
Find a behavioral change pt feels >7 on confidence and importance: 1. explain role as expert and coach 2. share dx and potential outcomes if no lifestyle/medical changes are made 3. describe lifestyle prescription and potential positive outcomes 4. identify progress using positive psychology 5. identify new areas for action 6. identify pt's confidence and importance level for each change (>7 likely to succeed) 7. have pt summarize goals (SMART) and resources needed 8. plan for obstacles/barriers/support 9. refer if necessary 10. confirm pt commitment (positive psychology)
JNC 8 HTN guidelines
JNC 8 recommends 4 drug classes for therapy ACE, ARB, CCB & Diuretics JNC 8 raises the systolic threshold level at age 60 (<150/90 over 60, <140/90 < 60 or DM or kidney dz) Treatment is recommended when the blood pressure is >150/90 mmHg There controversy concerning this recommendation-can produce syncope if treat too aggressively JNC 8 recommends a blood pressure <140/90 for those with CKD and/or diabetes Treat with an ACE or ARB
Health Belief Model
Looks at why people DON'T do a preventive strategy/behavior change 1. perceived susceptibility (individual fx) 2. perceived severity (individual fx) 3. perceived benefit 4. perceived barriers 5. cues to action (stimuli or triggers)-modifying fx 6. SELF-EFFICACY (confidence in ability for behavior change) ex: Zika virus - sexually active 24 yo woman in Miami would use prevention, but 80 yo man in KY maybe wouldn't -doesn't include habitual behaviors or emotional/social aspect of dz
Alcohol recommendations

Lifestyle Prescriptions
actions needed to trx or prevent a condition based on scientific evidence + pt's medical condition ex: prescribe 150 min mod PA/wk
Stress reaction
an internal event leading to an *external reaction* of alarm, activation of SNS, overstimulation, or internalization of the situation which -->maladaptive coping and breakdown of emotions
Physical activity
any mvmt of the body using energy beyond baseline and utilizing skeletal muscle contraction
Measures of Fitness
cardio: step testing muscular endurance: squats, push ups, sit ups flexibility: sit and reach body composition: skin calipers
Exercise Prescription
cardio=FITT: Frequency, Intensity, Type, Time strength=FIRS: frequency, intensity (weight), repetitions, sets resistance: intensity=5-6/10 x 8-12 reps beofre fatiguing flexibility: 2-4 reps, duration 10-30 sec x 2-3 for all muscle groups balance: start w/ hand hold support and eventually remove support, stand on uneven surface
stress response
external event leads to *internal conscious processing* that allows a person to be mindful of the situation, recognize influences and chain of event reactions and make a deliberate choice -allows for better emotional control, greater sense of calm/balance, mental equillibrium
Prediabetes lab dx
fasting serum glucose >=100 (5.6 mmol/L) and <126 2h OGTT serum glucose 140-199 a1c 5.7-6.4%
Hedonia
happiness is characterized by presence of positive emotions and absence of negative emotions humans are born empty and acquire meanting through social and cultural interaction ass'd with upregulation of pro-inflammatory genes
Eudaimonia
humans are born full of meaning and purpose and they discover (not acquire) it throughout their lives belief in this may help mitigate dz risk and promote longevity -ass'd with downregulation of pro-inflammatory genes, less amygdala activation, increased cortical fx, and improved reward circuit
Foods that + Inflammation
processed grains/sugar (<1 serving/day) processed meat/red meat (class 1 carcinogen for colon, stomach, pancreatic, prostate ca) harmful fats (trans, oxidized, solid)
exercise
purposeful, organized PA to improve or maintain one's health
Behavioral Determinants of Positive health outcomes
required: 1. trusting relationship bw pt and PCP 2. pt support from multidisciplinary team, family, community
Suffering
state of pain, distress, loss, damage, disability, hardship or death 2 kinds: 1. necessary (experienced by all humans): illness, old age, separation from loved ones, death 2. unnecessary (stems from egocentricity: our wants, likes, dislikes, attachments, etc): wanting a different outcome than the one that has happened, anticipatory thinking (imagining the worst), repeating stories about the past, trying to resist pain -judging w/out mercy + suffering -minimizing suffering: recognize poor thought patterns, attention>inattention, intentionally connect, order/regulation>disorder, ease>disease
Top food groups to avoid (minimum nutrients/calorie)
sugar sweetened beverages processed meats fried foods processed snack foods with added fat, sugar, salt confections high fat dairy red meats poultry eggs fish added fats/oils reduced fat dairy refined grains
fitness
