Major source of energy STORE in body Big diff between amount you eat and store Reservoir of energy / bank account Precursors of hormones and signaling molecules Steroid hormones (estrogen, testosterone) Prostaglandins and related Fat soluble vitamins: A , D, E, K Myelination of nerve fibers : allows efficient electrical impulse propagation in brain Insulation and heat conservation blubber? *** What are kinds of fats in the diet? (diff kinds of fat have diff impl.) Saturated: animal fats, milk products Effects on blood lipids -> heart disease Monounsaturated: olive oil (1 double bond) Polyunsaturated: vegetable oils (many double bonds) Omega-3 fatty acids: oily fish Solid at room temp bad for you Butter Lard More liquid the fatty acid better Cholesterol-rich fats Essential fatty acids: body cant make them What lipids do people eat 25-45% fat in typical macronutrient content of western diet Recommended diet: <30% energy from fat, <7% saturated Major differences in types of dietary fats Mediterranean (mono unsaturated), milk and meat (saturated), fish (omega 3) Sources of Body Fat: Fat in body is what you ate composition is very similar to the dietary fat Body can convert CHO and alcohol into fat novolipogenesis Storage of fats in adipose tissue Close to 150000 kcal in nonobese humans Great majority in adipose tissue living organism Complex biology Mature adipocytles which divide and die Blood vessels, structural elements Fat organ Secretes hormones into bloodstream (leptin, adiponectin) Types of depots and classes of adipose tissue Subcutaneous (under skin, pinchable), may be central (android) or gluteal-femoral (gynecoid pattern Visceral internal fat surrounding intestines Waist circumference or waist-hip ratio as risk factor for disease Waist may be as important as weight Hips have little to do with health Obesity defined by excess body fat stores Epidemic status in US and entire world Shift in demographics of obesity Used to be disease of rich older people Now less wealthy younger people (paediatric and young condition) Disease of adipose fat stores not defined by weight Accumulation of fat in non-adipose organs Fat that you see is not the only problem Fat spills over into other tissue, Fatty liver (now cause of cirrhosis) becomes inflamed and liver cells die, complication of energy metabolism Muscle associated with dysfunction of insulin or insulin resistance, precursor to diabetes Pancreas impaired secretion of insulin, contributes to diabetes Happens when storage capacity of fat in adipose tissue is inadequate Adipose tissue can have protective effects by sequestering stored fat compared to spillover fat of into organs and bloodstream Better to have fat in fat cells than other organs Diseases related to lipid utilization (absorption, carriage, storage) Fat malabsorption Billary disorders, pancreatic insufficiency, intestinal diseases Result in weight loss, altered stools -> can die of malnutrition if unable to absorb essential fats Hyperliperdemia (high fat content in blood) Common to western world Associated with cardiovascular disease Obesity Lipodystrophy (loss of fat stores, genetic or acquires) Cant store fat under skin Get side effects of obesity without being fat Deficiency Syndrome of Lipids Essential fatty acid deficiency rare in healthy people on western diet Malnutrition loss of fat soluble vitamins Lipoatrophy spillover of fat into organs / visceral adipose depots Cholesterol : most publicized and decorated molecule? XD Come from diet or synthesized by cells in diet Roughly about 50% from each source on typical Western diet High cholesterol intake partially suppresses synthesis by tissues (esp. liver reduces chol absorption efficiency of intestine dietary cholesterol has modest effects on blood cholesterol big distinction between the two Essential functions in cell membranes but most discussed in terms of risk for heart disease Fats not soluble in water packaged in lipoprotens to be carried in blood. Lipoproteins categoriesd by density classes Very low density, low density, high density, chylomicrons VLDL: transport lipids from liver to tissue LDL: transport choesterol from diet and liver to tissue HDL: reverse transport from diet and tissue to liver Diff association with risk of heart disease LDL: strong assoc with heart attacks and stroke HDL: inverse relation of heart disease Diet affects lipids Sat fat: raise LDL and VLDL Mono: reduce LDL and VDLD Omega3: reduce VLDL Trans: increase LDL Cholesterol: increases blood LDL Carbo: reduce LDL but increase VLDL (if simple sugars) Diet-heart hypothesis Dietary patterns assoc with different prevalence and risk of atherosclerotic heart disease Diet can influence blood lipids Blood lipids affect heart disease Alteration in diet -> Weak evidence for impact on heart disease incidence on death Alteration in blood lipids (drugs) -> very strong evidence for impact on heart disease incidence and death Summary Major energy store, high prop of dietary energy intake Main store is in adipose tissue Spillover from adipose tissue in bloodstream has adverse health consequences Where fat is located is important for health outcomes Relation btw diet, blood lipids and heart disease fairly well established, blood lipid lowering intervention key to modern medicine public health nutrition 2008-09-22 2008-09-22
