Estrogen's Protective Effects
Estrogen decreases: Hepatic production of cholesterol (lowers enzymes) Contraction of smooth muscle cells Homocysteine levels Estrogen Increases Hepatic LDL catabolism Insulin sensitivity Stimulates release of nitric oxide
Prevalence of Heart Disease
In 2000, there was in mortality 24% decrease for HD 10% decrease for stroke 2015 CDC- 1 in 4 deaths (610,000 per year) HD linked to deaths 3rd leading cause in 25-44 y/o 2nd leading cause in 45-64 y/o 1st leading cause in >65 y/o
Weight Gain
Mean body weight gradually increases with aging, peaking between 50 & 59 yrs
80/10/10 Diet
Often seen with vegan/raw type diets Concerns with pregnancy DHA, B12, vitamin D, iron, etc. Gene expression
Other Types of ED
Pregorexia- weight restriction, excess exercise Media driven (focus of weight loss after birth) SED (selective eating disorder)
Rehydration
Rehydrate slowly Guidelines Provide 1/4 to 1/3 overall fluid deficit Use water of 5% glucose solution Thickened liquids count as fluid Offering fluids hourly and with medication - achieve higher levels of hydration Dehydration at end of life ~ overall slowing down of body systems
Physiological Changes in Females Menopause
With cessation of menstruation, iron needs Daily Iron Requirement decreases to 8 mg Loss of estrogen effects: Urinary tract & vagina Heart Bones HRT Male Menopause
HDL
high density lipoproteins good cholesterol
Prognosis for People with Anorexia Nervosa
~4% die from the disease Deaths related to weakened immune system, gastric ruptures, cardiac arrhythmia, heart failure, & suicide Early diagnosis & treatment improves chances for recovery Recovery rates <50% fully recover ~33% show improvement ~20% chronically affected
Alcohol
~61% if U.S. adults drink alcohol ,1 and 2 rule Nations vary on alcohol consumption guidelines U.S. guidelines are "If you drink, do so in moderation" The Canadian guide states that >4 drinks at a time are risky
Vitamin D Council
1-70 600 IU 71+ 800 IU
Alcohol and Breast cancer
10/2015, International Journal of Cancer 334,000 women aged 35 to 70, across 10 European countries. Nearly 12,000 of the women developed breast cancer over the study period. risk of breast cancer quadrupled with each daily glass of wine or beer. The study wasn't designed to prove cause-and-effect, however, only to show an association. Breast cancer risk was stronger among women who started drinking prior to first pregnancy. Ethanol stimulates both cell proliferation and estrogen receptor signaling in the mammary gland.
LDL cholesterol level
100-129 near 130-159 borderline high 160-189 high 190 very high
Hypertension: Nutritional Remedies
2 main strategies: Maintaining healthy weight Reducing sodium to <1500 mg/d The new DGA also state that for individuals with prehypertension and hypertension "further reduction to 1,500 mg per day can [emphasis added] result in even greater blood pressure reduction." Other recommendations Moderation in alcohol Adequate potassium (4700mg), magnesium, & calcium intakes Following MyPyramid & DASH guidelines
Saturated FAT
2010 Harvard review article (Micha R, Mozaffarian D) replacing SFA with polyunsaturated fat modestly lowers coronary heart disease risk, with ~10% risk reduction for a 5% energy substitution; whereas replacing SFA with carbohydrate has no benefit and replacing SFA with monounsaturated fat has uncertain effects Issues with recommending "Avoid Saturated Fat" Replace with PUFA not CHO TC:HDL ratio is decreased by lauric acid but not palmitic acid
Almonds
2016 review (Journal of Nutritional Science) concluded almonds (45 grams per day= 2 servings= 2 oz) can lower LDL, total cholesterol and Triglycerides without harming HDL 1 cup = 105 grams I oz of almonds has 13 grams unsaturated fat 1 gram of saturated fat, 6 grams of protein, 4 grams fiber
Adults and ADHD
30-70% of children with ADHD retain attention related symptoms into adulthood Behavioral and Diet Treatments Avoid processed foods
Kidney Stones
5% of the world's population Stones= calcium and oxalate or phosphate Causes: low fluid intake, low calcium intake, excess body weight (uric acid stones), diabetes, foods high in oxalate (spinach, rhubarb, tea, chocolate, nuts, strawberries)
Prevention
A healthy diet should have a positive impact on health and not affect relationships with other people or quality of life and emotional states Orthorexia should be treated as a disorder concerning abnormal eating behavior that is linked with obsessive-compulsive symptoms Groups of people who may be at a higher risk for ON include athletes, medical students and professionals, and artists. There does not seem to be a significant difference between prevalence of ON in men and women. Proper nutrition education and avoiding classifying foods as "good" and "bad" may help prevent ON.
Treating Eating Disorders
A multidisciplinary team approach Team may consist of Physician Nutritionist Nurse Psychologist Psychiatrist
Hypertension: Prevalence and Etiology
AHA 2013: 77.9 million (1 out of every 3) adults have high blood pressure Only about half (52%) of people with high blood pressure have their condition under control.1 Nearly 1 of 3 American adults has prehypertension blood pressure numbers that are higher than normal, but not yet in the high blood pressure range. 64% of Americans with HTN have it under control Etiology Family history African Americans ~20% of cases linked to salt intake
Added Sugar Recommendations
AHA- 100 calories/25g/6 tsp for a woman, 150 calories/38g/9 tsp for a man 1 donut- 5-7 tsp, starbucks grande latte- 5 tsp, 1 DD coffee cake muffin= 14.5 tsp, 20 oz soda- 16 tsp, 6 oz strawberry yogurt- 3 tsp Natural sugars not a concern (except for juice)
Body Dissatisfaction
Adolescents with low levels of body satisfaction are more likely to use unhealthy weight control behaviors & participate in less physical activity
Water and Other Fluids
Adults can survive 3-4 days without water Fluid intake recommendations are 1 mL/kcal consumed At least 1500 mL if < 1500 kcal consumed In the average person, water in foods accounts for ~19% of fluid with ~81% from beverages Diuretic effects of caffeine and alcohol While caffeine does act as a diuretic, the DRI committee concluded caffeine-containing beverages contribute to the total daily water intake (maximum 400 mg)
Osteoarthritis
Affects ~7% of population, more common in men Etiology—cartilage loss, bone changes, hardening of soft tissues & inflammation Risk Factors Treatment- glucosamine with chondroitin (????) GAIT trial showed similar effects with placebo users- may help moderate to severe pain only, vitamin C/D (????)
Maintaining a Healthy Body
Age-Related Changes Caloric expenditure declines ~2% per decade during early adulthood Due to ddecrease in metabolic rate & decrease activity level Physical working capacity declines 5-10% per decade in older adults Declines accelerated with musculoskeletal disease, obesity and other conditions
Theories of Aging
Aging theory tries to explain physical & mental changes that accompany aging Theories fall into 3 groups Programmed aging Wear & tear theories Calorie restriction & longevity
Alzheimer's Disease 5.1 million $450,000,000 Autism 3.6 million $160,000,000 Schizophrenia 3.4 million $276,000,000 Eating disorders 30 million $28,000,000
Almost 50% of people with eating disorders meet the criteria for depression ED have the highest mortality rate for any mental disorder. Every hour a person dies from an eating disorder
Soy and Breast Caner Risk
American Association for Cancer Research (AACR) Annual Meeting 2015 Study in mice found genistein's ability to activate anti-tumor immune responses and reduce expression of immunosuppressive mechanisms may explain why lifetime genistein intake reduces risk of breast cancer recurrence critical that genistein is consumed well before a tumor develops to program the tumor to exhibit good immune responses Target at least 10 mg isoflavones daily (1/3 cup soy milk)
What is Orthorexia?
An obsession with eating foods that one considers healthy. Literal translation of Orthorexia: "righteous eating" or "correct appetite" Term coined by Steven Bratman, M.D. in 1997 Parallels with Anorexia Nervosa and Obsessive Compulsive Disorder There is no formal diagnosis criteria for Orthorexia
Treatment for CAD
Angina that is not life threatening- drugs, diet Angioplasty- narrowed arteries are dilated with a balloon so blood can flow more easily laser angioplasty Stents- short mesh tube made of wire used to prop open coronary arteries after angioplasty must take blood thinners to discourage clot formation Coronary Artery Bypass (CABG)- veins or arteries are used to bypass clogged or blocked arteries-improves blood supply to heart
Three Main Eating Disorders
Anorexia nervosa -Characterized by extreme wt loss, poor body image, & irrational fears of wt gain & obesity Bulimia nervosa -Characterized by recurrent episodes of rapid uncontrolled eating of large amounts of food in a short period of time frequently followed by purging Binge-eating disorder -Characterized by periodic binge eating not followed by vomiting or use of laxatives
tea (camellia sinensis)
Antioxidants Tea 400-600mg White Tea 300-400mg Jasmine Tea[1] 300-450mg Green Tea 130-200mg Black Tea 60-80mg Rooibos 'Tea'[2] ? (low) Instant Tea 20-110mg Iced tea
Changing Sensual Awareness: Appetite and Thirst
Appetite: Hunger & satiety cues weaken with age Older adults may need to be more conscious of food intake levels since appetite-regulating mechanisms may be blunted Thirst:: Thirst-regulating mechanisms decrease with age Studies support that dehydration occurs more quickly after fluid deprivation & rehydration is less effective with advancing age
Nov 2013- FDA proposes a ban on trans fats
Banning them completely could prevent 20,000 heart attacks and 7,000 deaths from heart disease each year No longer on GRAS list Ban is only for added not natural sources (meats) June 2015- officially banned
Etiology of HD
Begins when substances like cholesterol, fatty acids & calcium accumulate over injured arterial wall cells (oxidized LDL) levels of homocysteine, inflammatory diseases, abnormal blood clotting factors, etc. C-reactive protein below 1 mg/L protein found in blood plasma, whose levels rise in response to inflammation. It is an acute-phase protein of hepatic origin that increases following interleukin-6 secretion by macrophages and T cells. (1-3) average risk >3 high risk
Key points about Lactation
Benefits of DHA: Central nervous system development Increased IQ Better vision More mature central nervous system- better sleep Supplement recommended for breast fed infants Vitamin D- started within a few days of birth (400 IU) Recommendations about smoking, caffeine and alcohol use All ok during breast feeding (avoid second hand smoke while nursing)
Nutritional Interventions for Dehydration
Beverages Contribute Nutrients + Fluid Tea has flavonoids (antioxidants) Milk has calcium, protein, riboflavin, & vitamin D Cranberry juice may reduce UTI Fruit & vegetable juices count toward fruit & vegetable servings
Maximize Accuracy
Blood Pressure- measure sitting straight Certain medications, such as over-the-counter decongestants, prescription amphetamines and the steroid prednisone, can increase blood pressure. Full bladder can raise BP 10-15 points Do not talk and remove clothing from your arm Lipid Profile- avoid strenuous exercise 12-24 hours before which can falsely raise HDL Variations can be due to: birth control pills, hormone replacement therapy, steroids and blood pressure medications such as beta-blockers and diuretics which can raise cholesterol levels
Effects of CHD
Buildup of plaque & lesion leave less room for blood flow Results may be: Decreased blood flow to heart Reduced energy Decline in organ function Inability to perform ADL Shortness of breath Chest pain
four main types of kidney stones:
Calcium-containing stones - these make up a majority, nearly 75% of stones Uric acid stones - these make up about 10% of stones Struvite (infected) stones - these make up about 10% of stones and form after an infection in the urinary tract Cystine stones - these are stones that form from the amino acid cystine, the most uncommon Animal protein makes the urine more acidic, leading to less solubility for uric acid, and suppression of citrate formation. An alkaline pH favors the crystallization of calcium- and phosphate-containing stones, whereas and acidic urine pH promotes uric acid or cystine stones
Risk Nutrients
Certain nutrients exceed or fall short of recommendations Fiber Choline Vitamin A (increase of plasma levels and liver stores 4,000) limit Calcium Vitamin D Magnesium Vitamin E Potassium Folic acid Iron 8mg and B12 inability to split from protein carriers
Three Methods of Identifying Nutrition Risk Factors
Consider total fat, saturated fat, fruits, vegetables, whole grains & caloric intake Compare adequacy of nutrient intake to the RDA or DRI Examine a population & determine how environmental factors predict nutritional health—such as the Nutrition Screening Initiative's DETERMINE checklist do you have enough money, are you physically able to get it add up score to discover if at risk two: checklist and mini nutritional assessment
US Life Expectancy Drops for the First time since 1993 (CDC, 2016
Death rate raised for the first time in 10 years (733/100,000), higher HD/stroke rates On average, the overall life expectancy, for someone born in 2015, fell from 78.9 years to 78.8 years. The life expectancy for the average American man fell two-tenths of a year — from 76.5 to 76.3. For women, it dropped one-tenth — from 81.3 to 81.2 years.

Anorexia nervosa
Distorted body image and excessive dieting that leads to severe weight loss with a pathological fear of becoming fat. Low body weight, <85% IBW, denial of seriousness Intense fear of weight gain Restricting Type Binge-Eating/Purging Type Activity Type- excessive exercise, beyond what is required for health, not interested in athletic performance
concerns about ED
Do you care more about the virtue of what you eat than the pleasure you receive from eating it? Does your diet socially isolate you? Do you spend more than 3 hours a day thinking about healthy foods? When you eat the way you're supposed to, do you feel in total control?
Considerations that Guide Supplement Choices
Does it contain a balance of vitamins & minerals? When they are combined with fortified foods, is the dose still safe? Does it contain the missing nutrients? Does it carry a USP or NF code to ensure potency & purity? Is it safe?
infancy
Down's syndrome Decreased calorie needs due to small muscle size, feeding difficulties due to weak facial muscles- may need bottle use longer, may need to delay introduction of textures and cup, high risk of being overweight Severe preterm- may need parenteral or enteral feeding- may use a gastrostomy until able to take milk by mouth- usually will need milk fortifiers due to increased nutrient needs- needs extra protein and calories, extra vitamin E
Treatment for Osteoporosis
Drug therapy include: Bisphosphonates (Fosamax, Actonel, Boniva, Reclast)- inhibit bone resorption, increases BMD Parathyroid hormone (parathormone) Calcitonin- nasal spray Raloxifene (SERM) selective estrogen receptor modulator
Disordered Eating, Dieting and Eating Disorders
ED are not always about body image. They may also be related to loneliness, stress, depression, need for control or a boost in self esteem. They also could be related to food aversions, negative food perceptions or other psychological related reasons.

Maintaining a Healthy Body
Energy for Weight Management Caloric expenditure declines during adulthood Due to decrease in metabolic rate & increase activity level Energy expenditure remains constant if fat-free body mass stays constant
Osteoporosis
Etiology Inadequate bone mass resulting from: decrease.. calcium intake during ages 11-17 exercise (bed rest, sedentary life-style) Increased bone loss linked to: decrease.. blood calcium that increase PTH intake of Ca, Mg, Ph, Fl, Bo, & vit D & K weight-bearing activity blood Ph increase Ca release from bones

Stroke: Risk Factors
Family history African American, Asian, Hispanic Having prior stroke Long-term high blood pressure Cigarette smoking Diabetes mellitus Carotid artery disease, atrial fibrillation, transient ischemic attacks High red blood cell count Sickle cell anemia Poverty Drug abuse
Treatment/Prevention Kidney Stones-AND/American Academy of Physicians 2014
Fluids (2 L +, coffee, lemonade, citrus juice-Potassium citrate found in lemons (and other fruits and vegetables) can increase urinary citrate, which can protect against kidney stones) more common in white men over 40 if you take excessive amounts of vitamin D avoid high dose vitamin C (metabolized to oxalic acid) dietary or supplemental calcium (binds oxalate in GI tract before it reaches the kidneys) Avoid excess salt- increases urinary levels of calcium Eat smaller portions of meat (no more than 6 ounces a day). Purines found in animal-based proteins are associated with the formation of uric acid and calcium stones. Liver and other organ meats are especially rich in purines DASH diet helps prevent stone formation (high F/V) by making the urine less acidic
Food Advice Reflects Cultural Food Patterns
Food group guidance comes in many forms Canada uses a rainbow China uses a pagoda Japan's recommendations encourage enjoyment of meals: Use mealtime as an occasion for family communication Treasure family taste & home cooking
Plant Stanols and Sterols
Found in fruits, vegetables, nuts, seeds, legumes, wheat germ, veg oils Reduce LDL 5 to 15% (do not effect HDL), can use with a statin drug but not a replacement Similar in structure to cholesterol and compete for absorption in the intestine Less cholesterol and less bile is absorbed leading to body using cholesterol (taking it from circulation) to make bile Recommended intake, 2 grams per day (National Chol Education Program)- no benefit over 3 g per day Negative- can reduce absorption of Fat soluble vitamins
Comparison of Body Composition of a Young and an Old Adult
From age 20 to 70, the average man looses 24 lb of muscle & gains 22 lb of fat
AHA
Fruits and vegetables: At least 4.5 cups a day Fish (preferably oily fish): At least two 3.5-ounce servings a week Fiber-rich whole grains: At least three 1-ounce-equivalent servings a day Sodium: Less than 1,500 mg a day Sugar-sweetened beverages: No more than 450 calories (36 ounces) a week Nuts, legumes and seeds: At least 4 servings a week Processed meats: No more than 2 servings a week Saturated fat: Less than 7% of total energy intake (< 16 g if 2000 calories) Fat: 25-35%

The Promise of Prevention: Health Promotion
Good nutrition habits make a greater impact when started early in life Many people are not motivated to make changes until later in life or when health problems occur The belief that an 80 y/o is too old to learn and practice health promotion strategies is an outdated myth
Tea and Kidney stones
Green tea found to decrease risk (possibly due to antioxidants or change in shape of crystal) Green and herbal teas have lower levels of oxalate Black tea associated with higher risk
Heart Disease
HD is characterized by atherosclerosis, or hardening of arteries, due to plaque buildup Arteries narrow increasing risk of: Myocardial infarction shut off blood in heart (AKA heart attack) Strokeblood shut off to cerebral artery of the brain 1/3 of Americans have elevated LDL, 2/3's HTN
Added Sugars
HFC (55% fructose/45% glucose), table sugar (50% fructose/50% glucose) Fructose may raise TG more than glucose, may also contribute to visceral fat, may raise risk of gout (fructose raises uric acid levels- which also inhibits Nitric Oxide and impairs glucose uptake)
Common Botanicals and Nutraceuticals
Herbs and spices (Rosemary, sage, thyme, cinnamon, clove, & ginger) Protect against oxidative stress Caffeine and guarana Stimulant—older people become more sensitive Black & green teas Phytochemicals like catechins & flavonols that are antioxidants Garlic Allicin (antibacterial) Ajoene (blood thinner)
HDL 60 mg/dL and above
High HDL cholesterol. An HDL of 60 mg/dL and above is considered protective against heart disease.
240 mg/dL and above
High blood cholesterol. A person with this level has more than twice the risk of coronary heart disease as someone whose cholesterol is below 200 mg/dL.
Prevalence of Dementia
In the U.S. 14% of older adults (>70) have dementia ~10% have Alzheimer's disease (AD) Prevalence with age AD ranks 6th in leading cause of death for adults >65 years (5.4 million Americans have AD)
Protein
Inactive, older adults living alone may have low protein intakes Several researchers report protein needs for older adults are 1 to 1.3 g/kg body wt (higher than the DRI of 0.8 g) risk of stroke went down 26% for every increase of 20 grams of protein in the daily diet. (Neurology, 6/2014) Higher protein intakes (about 100 g/day) associated with lower BP (Am J HTN, 9/2014) (due to nitric oxide and sodium regulation) Nitrogen balance is easier to achieve when: Protein is a high quality Adequate calories are consumed Elders participate in resistance training
Sarcopenia Obesity
Increased body fat and decreased muscle mass and quality Associated with deteriorations in physical disability, morbidity, and mortality Risk factors: excessive energy intake, physical inactivity, low-grade inflammation, insulin resistance and changes in hormones Together- higher risk of metabolic syndrome than sarcopenia or obesity alone
Energy for Weight Change (old method)
Initially~3500 kcal needed to lose (or gain) 1 lb (1958 rule for weight loss) Either +/- 500 kcal/day to gain or lose 1 lb a week (short term) When losing weight- over time 3500 cal/lb will become an over estimate due to physiological changes that result in a lower BMR Two new weight loss calculators provide conservative estimates of weight loss
Age-associated Changes in Metabolism: Nutrients of Concern
Iron Iron needs after menopause (8 mg) Most older adults consume more iron than needed Most 50+ MVIs do not contain iron Excess iron contributes to oxidative stress Reasons that some older adults may have iron deficiency include Iron loss from disease or medications acid secretion calorie intake
Childhood
Iron deficiency anemia Risk factors are: cow's milk given before 12 months, drinking more than 24 oz per day of cows milk, poor diet, low income, chronic illness Nutritional Intervention: iron fortified foods (cereals, meat, vitamin C) multivitamin with iron Cystic Fibrosis (treatments) 1.Increased calorie/protein needs 2-4 times above normal 2. digestive enzyme supplements 3. fat soluble vitamin supplements or multivitamin Disease causes excess mucus production which blocks pancreas and fills lungs making it hard to breath ADHD (attention deficit hyperactivity disorder) Nutritional interventions: avoid TV at meal times, avoid preservatives and artificial food dyes, time meals when medications are at low peaks since meds decrease appetite. Try magnesium, omega 3 and zinc supplements. PKU (genetic disorder) Avoid protein foods and nutrasweet (aspartame) use PKU supplements, low protein food supplements/products
Why a Gender Difference?
It is not completely clear why the difference, but the following may explain the difference: Size and pumping ability of right side of heart differs between men and women blood vessel walls of the very small arteries that branch out from the coronary arteries are more likely to be damaged in women as compared to men. Researchers are still learning about the role hormones play in women's heart health.
Other Dietary Supplements
Kava Muscle relaxant & anticonvulsant Found effective for menopausal symptoms Side effect liver toxicity

LBW Causes- adolescent pregnancies, lack of prenatal care, poor weight gain, low income, normal weight woman should gain 25-35 lbs. Pre-eclampsia Risk factors- low physical activity, obesity, diabetes, insulin resistance, smoking, age over 35, inadequate antioxidants, high trans fats in the diet Treatment- PA and vitamin D Fetal Alcohol Syndrome No safe level of alcohol Causes behavioral problems, aggression, short attention span, stunted growth, birth defects. Nausea (morning sickness) Ginger, B6, small frequent meals
Physical Activity Recommendations
Lack of physical activity is associated with higher risk of death or disability At least 30 minutes/day of physical activity Resistance training at least 2 times a week More than 80 percent of adults do not meet the guidelines for both aerobic and muscle-strengthening activities Less than one-quarter of adults over 45 meet the muscle-strengthening recommendations set by the Department of Health and Human Services
Considerations for Educational Materials for Older Adults
Larger type size Serif lettering (such as Times Roman) Bold Type High contrasts (black on white) Non-glossy paper Avoid blue, green & violent Reading level of 5th to 8th grade
Physiological Changes

What to Do
Learn about Eating Disorders Talk in a non-threatening manner IMAD approach Inefficiency Misery Alienation Disturbance Emphasize concern for them and their health
Life Expectancy and Life Span
Life expectancy (78.8) (81/76) Average number of years of life remaining for persons in a population cohort or group; most commonly reported as life expectancy from birth http://www.cdc.gov/nchs/data/nvsr/nvsr65/nvsr65_04.pdf (changes in life expectancy M/F, W/B) Life span Maximum number of years someone might live; human life span is projected to range from 110 to 120 years
Warning signs of an ED
Loose fitting clothes, many layers, winter coat indoors Role models are thin celebrities Lies about food, hides food/dishes, often says they already ate Excuses self after meals, anxiety over eating Cutting food up into small bites, pushing it around plate, hiding food under napkins Social isolation Reading cookbooks/food magazines/websites, cooking foods but not eating them Excessive gum chewing or diet soda/water consumption
HDL Less than 40 mg/dL (for men) Less than 50 mg/dL (for women)
Low HDL cholesterol. A major risk factor for heart disease.
New AHA guidelines released 11/12/13
MI/stroke risk equations (AA have separate equation) for 10 year and lifetime risk Target cholesterol numbers only refer to those with very high levels Statin Drug therapy recommendations New dietary and exercise recommendations 40 minutes moderate intensity activity 3-4 x a week Diet pattern emphasized (occasional indulgences ok)
Etiology of Eating Disorders
Main groups of contributing factors for eating disorders psycho-developmental factors: bodily changes, life transitions socioculture factors: peers, media, lifestyle, family values neurochemical or genetic factors: brain chemistries, dna, personality structure 50-80% of the risk for anorexia and bulimia is genetic.
Actual Energy Intake Using Food Disappearance Data
Main source of calories ages 2+ grain based desserts, followed by bread for adults and young children 2014 USDA survey- average American is consuming 118 fewer calories per day compared to 10 years ago
WHO- 3/2015 Sugar Recommendations
Maximum of 10% of total calories Aim for no more than 5% of total calories Added sugars includes fruit juice 2000 calorie diet (100 calories max or 6 oz of juice a day) In the U.S., adults get about 11 to 15 percent of their calories from sugar; children about 16 percent.

MIND Diet
Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) diet - was created by nutritional epidemiologist Martha Clare Morris, PhD, and colleagues at Rush. It consists of 15 dietary components: 10 "brain-healthy food groups" and five unhealthy food groups. Green leafy vegetables, other vegetables, nuts, berries, beans, whole grains, fish, poultry, olive oil and wine make up the brain-healthy foods, while red meats, butter and stick margarine, cheese, pastries and sweets, and fried or fast food are the food groups that should be limited Moderate adherence to MIND diet reduced Alzheimer's risk by 35%

More Americans are living longer Currently, ~46.2 million >65 yrs By 2060, ~98 million will be >65 yrs Persons ≥85 are the fastest growing population group
Treatment
Multidisciplinary Varies based on symptoms and severity Focus on understanding that quality of food is not the only determinant of health Cognitive behavioral therapy Patients tend to respond well to treatment because of their concerns with health and self-care Focus on nutrition education, all foods can fit Food is many things (nourishment, culture, tradition, holidays, enery)
Nutrition Interventions
National Cholesterol Education Program Total fat intake from 25-35% of calories Sat. <7% calories (2010 DG) Mono up to 20% calories Poly <10% calories CHO from 50-60% calories Dietary fiber 20-30 g/day (10-25 g soluble) Plant stanols or sterols: 2 g/day Weight reduction for obese ≥200 cal/day spent for physical activity
Treatment
Need to change irrational thinking Focus on food as nourishment vs as a tool to control or punish Promote positive self esteem Retraining body to recognize hunger and fullness Avoid trigger foods, obsessive behaviors Break the chain or cycle exercises Avoid "don't eat" messages
Consequences of Smoking
Nicotine decreases the strength of hunger contractions of the stomach, increases blood sugar levels, and deadens taste buds When a smoker tries to quit, food becomes more appealing due to the increased sense of taste and smell Wrinkles Bone loss Stained teeth Infertility SIDS Early onset of menopause
Freeze Dried F/V

The Source of Physiologically Active Compounds
Over 4,800 chemical compounds are found in tobacco smoke, 60+ carcinogenic Nicotine Addictive stimulant Acts upon the dopamine neurotransmitter in the brain to cause excitement Causes serious effects upon the cardiovascular system tar (phenol, cresol, benzopyrene, DDT) Accumulates in the alveoli (sacs in the lung tissue) and inhibits lung function Disables the function of cilia
heart attack
Oxidized LDL cholesterol creates an "injury" by burrowing into the artery wall. 2. The immune system sends inflammatory cells like monocytes to heal the injury. 3. Monocytes enter the wall and turn into macrophages, which gobble up the LDL cholesterol. 4. The LDL-stuffed macrophages form a "fatty streak." 5. Over decades, more cholesterol, connective tissue, calcium, and cell debris accumulate, turning the streak into plaque. Smooth muscle cells form a fibrous cap over the plaque. 6. Macrophages break down the cap. 7. The cap ruptures. When a clot forms around the rupture, blood flow is blocked, which triggers a heart attack or stroke.
PANERA first to post added sugars
Panera has reformulated two of its proprietary drinks, Passion Papaya Green Tea and Agave Lemonade, reducing their sugar content by roughly 40 percent.

Effects of Diabetes
Short Term Blurred vision urination weight infections decrease wound healing Hunger & thirst Long Term Heart disease Hypertension Stroke Poor circulation Blindness Kidney failure Loss of limbs
Orthorexia
Similarities with other eating disorders Need for control May lead to malnutrition and weight loss Often share common history with anorexic patients- detailed, careful, tidy, etc. Different from AN and BN in that the obsession is with quality and purity rather than quantity and does not stem from a desire for weight loss or poor body image. Similarities with obsessive-compulsive disorders include perfectionism, control, and phobic and hypochondriac mechanisms.
To use or not? Potential Drawbacks of Increasing Dietary Phytoestrogens
Soy has estrogenic effects Soy increases the risk for breast cancer in test tubes and rodents, not in case control studies Taste of soy is unappealing/GI side effects Flax in large amounts (>1.5 oz) acts as a laxative Soy is not a "magic pill" but it can improve diet quality.
