Diet and Disease The Phantom Menace Part 5 of 6 The Aetiology of Obesity

2 Hormonal Obesity Theory
Vinegar Fibre Obesity High Protein High TG Low HDL Increased Insulin level Fattening Carbohydrates Hypertension Cortisol Diabetes Wheat Super-carbohydrate Fasting Fatty Liver Key is INSULIN How does it link to diseases, not just risk factors Insulin Resistance Metabolic Syndrome Fructose

3 Diseases of Civilization
Coronary Artery Disease Obesity Diabetes Colorectal cancer Breast cancer Tooth decay Constipation Western Diseases Certain diseases are rare to non existent amongst isolated populations that lived traditional lifestyles and ate traditional diets African missionaries Dr. Schweitzer “On my arrival in Gabon, I was astonished to encounter no cases of cancer” Over the ensuing decades he witnessed a steady increase in cancer “My observations inclined me to attribute this to the fact that the native were living more and more after the manner of the whites” Dr. Schweitzer West Africa 1913

4 1908 Smithsonian Institution’s Bureau of American Ethnology report
First Nations “Malignant disease, if they exist at all … must be extremely rare” “Not one pronounced instance of advanced arterial sclerosis” life expectancy was as long or longer than the local white population 1910 – Indian Affairs Bureau survey of physicians 115,000 Native Americans only 29 documented cases of malignant tumours 1908 Smithsonian Institution’s Bureau of American Ethnology report

5 Inuit 1952 Queen’s University 1950-1974 Upernavik 1 case of diabetes
“It is commonly stated that cancer does not occur in the Eskimos, and to our knowledge no case has so far been reported” Upernavik 1 case of diabetes 1902 – Samuel Hutton “The Eskimo is a meat eater, the vegetable part of his diet is a meager one” Did not see or hear of a case of malignant growth in an Eskimo in 11 years Town of Upernavik 1800 population

6 Masai www.kidneylifescience.ca
Kenya and Tanzania Hypertension and obesity almost non-existent Pastoralists – diet of milk, meat and blood Rarely eat fresh vegetables

7 Tukisenta www.kidneylifescience.ca
“Investigators found them to be fit, lean and muscular, with no sign of protein deficiency” (Trowell and Burkitt. Western Diseases. 1981) 94.6% of their energy intake as carbohydrate New Guinea highland tribe studied extensively in the 1960s and 70s

8 The Kitava Study www.kidneylifescience.ca
No indications of stroke, diabetes, dementia or congestive heart failure No obesity (yam, sweet potato, taro, tapioca) Excellent blood pressure – Dr Lindeberg 1990s - Kitavan diet 69% carbohydrate Fruit, vegetables, roots, fish and coconuts

9 Low Serum Insulin despite high carb intake
Swedish reference range 10-90% Less than 0.2% of the caloric intake came from Western food, such as edible fats, dairy products, sugar, cereals, and alcohol Despite high carbohydrate intake, serum insulin levels low But all carbohydrates are unrefined Low Serum Insulin in Traditional Pacific Islanders—The Kitava Study Metabolism, Vol 48, No 10 (Oct), 1999: Lindeberg S

10 Okinawa Life expectancy among the highest in the world
85% Carbohydrate BMI average of 20.4 Noted for their low mortality from cardiovascular disease Traditional diet compared to Japanese average 20% less calories 300% of the green/yellow vegetables Less Rice, the staple was the sweet potato 25% of the sugar

11 Conclusions www.kidneylifescience.ca
Populations could be healthy with diets of 95% carbohydrate or 95% meat No refined/ processed foods No flour No sugar Rare to find “Western diseases” in peoples eating traditional diets Low serum insulin levels

12 Populations in Transition

13 Tokelau Island Migration Study
1841 Dietary staples coconuts, fish and breadfruit 70% of calories from coconut 1966 Threat of over-population due to cyclone more than half of Tokelauans moved to mainland (New Zealand) “Their populations are notable for their low levels of blood pressure… coronary heart disease, obesity and diabetes”

14 Tokelau Island Migration Study

Despite increased physical activity – very high prevalence of obesity High levels of physical activity

21 Maori Obesity www.kidneylifescience.ca
Staples of Maori diet - bread, flour, biscuits, breakfast cereals, sugar, and potatoes

22 Increasing cancer with Westernization
Nutritional transition – Westernization of diet, lifestyle, and health status Eskimos living near European settlers ate a “settler’s dietary” mostly “tea, bread, ship’s biscuits, molasses, and salt fish or pork” – refined carbohydrates

23 Increasing Cancer with Westernization

27 The Saccharine Disease
Refining of Carbohydrates 1. Overconsumption – evades satiety signals 2. Removal of protein – speeds digestion 3. Removal of fibre – speeds digestion 4. Removal of fat – speeds digestion George Campbell and Dr. Cleave – argued that Western diseases constituted the manifestations of a single primary disorder that could be called “refined carbohydrate disease” Theory eventually replaced in 1977 by McGovern and Dietary Fat Hypothesis 1966 ‘Refined-carbohydrate disease’

28 Metabolic Syndrome www.kidneylifescience.ca Abdominal obesity
High triglycerides, low HDL Hypertension Diabetes Insulin resistance Elevated uric acid levels Alzheimers’ disease Gallstones Fatty liver 1980’s - metabolic abnormalities common to obesity, diabetes, and heart disease Clustering of risk factors suggests a common cause Diseases identical to ‘diseases of civilization’ Gerald Reaven (Stanford)

For saxagliptin (Onglyza), the relative risk reduction of cardiovascular events was calculated to be 0.43 in a meta-analysis of 4,607 patients, with confidence intervals of 0.23 and 0.80. For linagliptin (Trajenta), the relative risk reduction was calculated to be 0.34 in a meta-analysis of 5,239 patients, with confidence intervals of 0.16 and It is important to note that the main contributor to the number of events was a head-to-head study of linagliptin vs. sulfonylureas. When linagliptin was compared to placebo, the comparison was not statistically significant (per Trajenta Canadian Product Monograph, July 2011). Given the fact that the study program for each of the drugs varied considerably with regard to study population, comparator, duration of follow-up, etc., one should not compare the results of one drug vs. another.

48 Nutrition Recommendations 2008
“Intake of sucrose and sucrose-containing foods by people with diabetes does not need to be restricted because of concern about aggravating hyperglycemia” (it’s true – they really wrote this) Page S65 WTF?? Diabetes Care 1 Jan 2008 Vol 31 S61-81

49 Nutrition Recommendations 2008
“Dietary strategies including reduced calories and reduced intake of dietary fat, can reduce the risk for developing diabetes and are therefore recommended.” Diabetes Care 1 Jan 2008 Vol 31 S61-81 A position statement of the American Diabetes Association EAT LESS MOVE MORE

51 Editorial Dr. David Allen
“Chronic caloric surplus is a central cause of epidemic type 2 diabetes” (so, so wrong) “Because changes in eating and activity habits were calculated to decrease baseline weight by 7 to 10%, most participants clearly did not adopt these habits” (blame the victim) “Lifestyle change by definition works and that any lack of effect is therefore due to poor adherence” (blame the victim) “Eat Less, Move More” Flawed advice “40 year perfect record - unblemished by success” Cannot believe their own advice is flawed and therefore blame must lie with patients Advice that has never worked in the history of dieting

52 NIH Trial Of Lifestyle Intervention For Type 2 Diabetes Stopped For Futility After 11 Years Forbes October 19, 2012 LOOK-AHEAD trial – 5,145 overweight diabetic patients Low Fat, Low Calorie diet ( kcal) Meal replacement products, Increased exercise (175 min/week) Eat less, move more “A low fat diet (<30% of kcal from fat with <10% saturated fat) and increased physical activity are key components of the intervention” Maintained weight loss of 5% over 4 years compared to 1% in control group randomized to lifestyle intervention or usual care Advice to ‘eat less, move more’ DOES NOT WORK – key is not calories but insulin
