Obesogenic culture (AHA ’03) Avge US adult sedentary 8 hours / day, < 2,000 steps / day (NYS Public Health Assocn ‘05) Amish 16,000 steps /day: obesity 9% women, 0% men (Bassett et al ’04)
Positive energy balance 1940 50 60 70 80 90 2000 DoH ’98, USDA ’02, NIH ’03, NCHS ‘04
AHA 2002: ‘obesogenic culture’ • Fewer bus-stops, remote parking • Exercise to be mandatory at all levels of educational system • No ‘junk foods’ to be sold / served in schools • ‘baby bells’: constructive inconvenience
Why is weight gain so easy? • Multiple satiation mechanisms • Protein: amino acids (fish > whey > casein) • Fats: fatty acids (distal jejeunum) • Carbs: glucose (Hoodia) • Fermentable carbs: SCFA (propionic) • Insufficient calorific throughput • High calorific density • Instant gratification

Overweight but starving • W.H.O. ‘02: ‘Globally, overweight more of a health problem than underweight.’ • U.N.O. ’06: ‘Overweight but malnourished’ (=Type B malnutrition) • 40-60%hospital admissions malnourished(US/UK) • And in the community (USDA and other surveys)

DIETARY SHIFT • Flavonoids 75% • Vit C 50-60% • Omega-3 50% • Methyl groups 95% • Carotenoids 40% • Phospholipids 50% since 1900 • Selenium 50% ” 1960 (UK) • Prebiotic fiber 50% ” 1960 (Fr) • Sterols 66% ” 1960 (SA) since Stone Age
WHO Technical Report Series 916 • ‘Diet, Nutrition and the Prevention of Chronic Diseases’ • Report of Joint FAO / WHO Expert Consultation Geneva May 2003
RSM 2005: Pathogenic culture? heart disease, stroke, cancers, kidney disease, blindness, Alzheimer’s • Type 2 diabetes • Osteoporosis • ARMD • Neurodegenerative disease • Lymphoma, leukaemia, melanoma, germ cell tumours in teens & young adults • ADD / ADHD / dysphasia / dyspraxia • Allergy, asthma
Type B Malnutrition worsens with age • Reduced activity / calorie requirements • Institutional diet • Financial hardship • Poor dentition • Swallowing problems (xerostomia) • Loss of sense of taste
Type B Malnutrition worsens with age • Progressive depletion of anabolic factors (vits C, B’s, D; Zn, Cu, Se, Fe, Ca, Mg; amino acids etc) • Progressive depletion of anti-catabolic factors (vit E; Zn, Cu, Mn, Se; sterols, flavonoids, carotenoids etc)
Type B Malnutrition worsens with age • Progressive depletion of anabolic factors decreased tissue repair, damage clearance etc • Progressive depletion of anti-catabolic factors increased free radical activity, hexosylation, nitrosation, inflammation = CATABOLIC DOMINANCE
Multiple agent intervention • CDD’s have multiple patho-aetiology • CAD risk factors: hypertension, smoking, inactivity, obesity LDL / HDL, LDL-ox.lag, HbA1c, hyperHc, ICAM-1, VCAM-1, VWF etc • Reduced risk: lycopene, quercitin, omega 3, methyl groups, alcohol, lutein, vitamin E, soy etc
