(what is it made from?)– Where is it stored? – Where is it secreted into?– What does it do?– Why is it necessary?Review QuestionsBiology 45• What is it? • Where is it made?• When is it secreted into the blood?• What is the target organ?• What does it do?• It is found in the brain. What might it be doing there?Cholecystokinin (CCK)Biology 45 - DigestionAnna Miller, MS, RDBiology 45Questions!• What are the end products of…..– Carbohydrate digestion?– Protein digestion?– Fat digestion?Biology 45Digestive Problems• Highlight for chapter 3• Not responsible for:– Choking– Vomiting– Belching and Gas• You Are responsible for:– Diarrhea (irritable bowel syndrome, colitis)– Constipation (Hemorrhoids, diverticula)– Heartburn and Acid Indigestion (GERD)– Ulcers (not caused by stress or spicy food!)Biology 45Diverticula in the ColonBiology 45 - DigestionAnna Miller, MS, RDBiology 45Gastroesophageal RefluxGERD (GastroEsophageal Reflux Disease) Biology 45Claims:1. CHO and protein cannot be digested at the same time. If you eat them together, they won’t get digested, they’ll turn to toxic substances that turn to fat2. You should not drink 1 hour before eating/2 hours after eating because this dilutes enzymes, leading to food not being digested…you get fat3. The diet consists of eating fruit only for breakfast, protein for lunch, CHO for dinner“Food Combining” Diet•What is inaccurate about these claims?•Why did some people lose weight on this diet?Biology 45A Few Ways to Avoid “Indigestion”• Don’t overeat !!• Eat regular meals and snacks, with CHO, protein & fat • Don’t eat fast• Be relaxed while eating • Reduce stress level in general• Don’t exceed moderate alcohol• Get enough sleep and
