Document Summary
Chapter 4: the carbohydrates: sugar, starch, glycogen, & fiber: carbohydrates, ideal nutrients, meet body"s energy needs. Keep your body lean: critical and primary energy source, nerve cells, red blood cells, and brain, carbohydrate rich foods: whole foods and fiber-providing foods. Plants (grains, fruits, vegetables, & legumes: milk ( lactose = milk sugar, sugars: simple carbohydrate ; chemical name ends in -ose. Sucrose: glucose + fructose: maltose: glucose + glucose. Ability to digest lactose varies: lactase enzyme (responsible for lactose digestion, made by small intestine, milk allergy: reactions to milk protein. Symptoms of intolerance (non functioning lactase enzymes: nausea, pain, diarrhea, and gas, milk tolerances and strategies: lactase-treated products, lactase pills, yogurt or aged cheese, or milk substitutes (soy, nut, grain-based beverage, starch (polysaccharides): complex carbohydrate. Supporting structure of plant parts: digestion involves bacterial fermentation (feeding large intestine bacteria, glycogen. Tightly controls blood glucose concentration: glucose is broken in half (splitting glucose for energy (atp), can reassemble.
