Unformatted text preview: Carbohydrates: Sugars, Starch & Fiber HS201 Prof Joan Salge Blake, MS, RD, LDN Carbohydrate Basics The primary role of carbohydrates is to provide the body with energy (calories). Carbohydrates are the preferred fuel for the nervous system, including brain , and RBC . Carbohydrates are the ideal fuel compared to other alternatives: Less expensive than protein. High-fat diets are associated with chronic disease. Carbohydrates: compounds made of single sugars or multiples of them and composed of carbon, hydrogen, and oxygen atoms. carbo = carbon (C) hydrate = water (H 2 O) Photosynthesis During photosynthesis, the plants absorb the energy from the sun through chlorophyll The simple sugar, glucose , is made of water and carbon dioxide. The plant links glucose units together to form starch . Carbohydrates are made up of carbon , hydrogen and oxygen . Complex carbohydrates Polysaccharides (Starch and fiber ) Simple carbohydrates Monosaccharides & Disaccharides (Sugars) Figure 4.2 Figure 4.3 Maintaining Your Blood Glucose Level Insulin: a hormone secreted by the pancreas in response to high blood glucose levels; it directs the glucose from your blood into your cells. Glucagon (GLUE-cuh-gon): a hormone released by the pancreas that signals the liver to release glucose into the bloodstream. Surplus of glucose is stored in your liver and muscles cells as Glycogen Limited Capacity! Excess calories from any source will be stored as: FAT!! Insulin Directs Excess Glucose into Storage Figure 4.5a Fasting No Food, No Fuel Breakdown stored energy (glycogen & fat) for fuel. Glucagon Directs the Increase of Glucose in the Blood Figure 4.5b During Fasting, No CHO Cause incomplete burning of fat and creates ketone bodies Causes ketosis Fat Burns In The Flame of CHO Gluconeogenesis Gluco = sugar Neo = new Gensesis = origin Protein Figure 4.5 How Much Carbohydrates? Minimum 130 grams daily DRI: 2000 calorie diet 225-325 grams of carbs daily 45 to 65% of your daily calories Figure 4.6 But What Type? Simple Carbohydrates or Complex Carbohydrates The Wheat Kernel: A Whole Grain Germ : the nutrient-rich and fat-dense inner part of a whole grain. Endosperm : provides energy; contains starch grains Bran : the fibrous protective, source of fiber, B vitamins, and trace minerals. Husk : (chaff) the outer, inedible covering of a grain. Refined Left Behind Enriched Folic acid, thiamin, niacin, riboflavin, iron Whole Grain Has everything! > 85% OF THE GRAINS THAT ARE EATEN ARE NOT NOT WHOLEGRAINS Finding Whole Grains Finding Whole Grains 100% Whole Wheat Bread Whole Grain Cereal Oatmeal Brown Rice Popcorn (Who knew?) FIBER Source: 1994-1996 CSFII/DHKS, USDA 14 19 35 5 10 15 20 25 30 35 40 20+ year old females 20+ year old males GOAL (20-35 grams) Grams of Fiber per Day Daily Fiber Goal: 20-35 grams...
