What’s a Concept map?

Example: Photosynthesis Terms: solar energy, food energy, CO 2, H 2 O, O 2, green plants solar energy green plants CO 2 H2OH2O glucose + O 2 food energy

Concept Map: Objective: to help see the link between terms and ideas learned in class Terms: simple carb, fiber, fructose, added sugar, glucose, complex carb, natural sugar, sucrose, glycogen, lactose, starch, grains, honey, plain yogurt, pears, liver and muscle stores. Practice: Draw a diagram logically linking all of the terms. carbohydrates

Blood Sugar Lows and Highs

Tools for Control-Overview  Insulin (I) Protein based, pancreas produced hormone Attaches to cells-Allows glucose inside cell Result  blood glucose (sugar) level decreases  Glucagon (G) raises blood sugar level (BSL)  Goal BSL ~ mg %  Too high or too low= TROUBLE

dizzy, confused sweaty, rapid heart rate grouchy, anxious To: TREAT ACUTE SYMPTOMS: simple carb (sugars) To: PREVENT SYPTOMS: restrict simple carb (sugars) Low blood sugar

Hypoglycemia (Low BSL)  Acute danger but uncommon condition  RBC’s and brain need glucose 24/7  Basic Cause: I:G out of balance  low BSL  Prevention (different than treatment) No meal skipping Include healthy complex carb/protein at meals Limit simple and avoid ‘added’ sugar Focus naturally high fiber foods

Diabetes Projections: 2000 to 2030

Diabetes Mellitus (DM)  Hyperglycemia (high fasting BSL)  Cause: not enough or ineffective Insulin Not caused by consuming too much sugar!  Result: too much sugar in blood-not enough in cell  Consequence: cells/tissues are glucose starved chronic inflammation occurs blood lipids, blood pressure rise, arteries harden tissue/cell function declines

DM: A chronic, progressive disease  Common consequences Vascular disease (#1 cause-diabetic deaths) Blindness Amputations Kidney disease

Renal Dialysis

Classifications of Diabetes  Type I pancreas fails to make insulin early onset in life Rx: requires insulin. Monitor diet, regular exercise.

Classifications of Diabetes  Type % of all cases Insulin is ineffective Most adult DM Increasingly common in kids Treatment: Medical  pills/injections Lifestyle  diet/exercise/stress mgt.

Self-Check BSL Helps gauge day to day management success Fasting BSL ✓ morning, bedtime and/or exercise Long term ✓ of BSL = hemoglobin A1C

 Achieve a healthy weight  Quit smoking  Daily exercise  Trickle in healthy carbs over the day  No meal skipping  Foods/beverages without added sugar  Replace saturated (animal) with unsat (plant) fats  Monitor BSL Check List: Managing BSL

Concept Map: Terms: blood sugar (glucose), hyperglycemia, hypoglycemia, glucagon, insulin, type 1 diabetes, type 2 diabetes, ineffective insulin, inadequate insulin Draw a diagram logically linking all of the terms. Blood Sugar Level

Key Terms Hemoglobin A1c (A1c) Measures percentage of hemoglobin proteins in red blood cells that are attached to glucose. Higher blood glucose levels are, the more glucose attaches to hemoglobin. Once glucose binds with hemoglobin, molecule has 120 day lifespan of hemoglobin A1c represents blood glucose levels over 2-3 months.

Reduce Risk Type 2 Diabetes  People with prediabetes reduced their risk of type 2 diabetes by: Weight loss (~7% of body weight) Exercise (150 minutes/week) Diet rich in whole-grains and fiber Coffee (1-4 cups/day) and moderate alcohol (1-2 drinks/day) Adequate vitamin D status supports insulin production by the pancreas

Type 1 Diabetes  Type 1 diabetes is an autoimmune disease that produces an insulin deficiency 5 – 10% of diabetes  Develops when the immune system destroys insulin-producing beta cells in the pancreas  Triggered by medications or viral infection in genetically susceptible people

Correlation Cause and Effect  A and B often happen together when the doorbell rings the cat hides maybe the cat hides because the loud bell makes the dog bark and this makes the cat hide  A  B A causes B to happen when my dog hears a loud bell, she barks

Vitamin D Status and DM 1 ???  Vit D intake and risk of DM1: a birth cohort study Lancet 2001 Nov 3:358  infants followed from  Infants given 2000 IU Vit D regularly decreased incidence of DM 78% at 30 yr marker  Study only suggests Vit D prevents DM 1

Vitamin D Status and DM 2 ???  Insulin Sensitivity measured in 126 college students  Low Vit D (<20ng/ml)  poor beta cell function  Increase Vit D (to 30ng/ml)  60% improved Insulin sensitivity (decrease DM risk)  Am Jour Clin Nutrition 2004  Study only suggests Vit D prevents DM2
