Health. Healthy diet: Toxicity: Nutrient Toxicity: Deficiency: Nutrient Deficiency: phytonutrient: 1/14/21 Module 2 The absence of disease A diet that minimizes your rick of a disorder or disease Too much of something Too much of a nutrient which causes signs or symptoms. Too little of something Too little of a nutrient wich causes signs or symprons A Non-essential nutrient that if we include in our diet has health benefit Macronutrients Micronutrients "Carbohydrates Vitamins Proteins nave chords a coloriss Minerals 'fats (lipias) Phytonutrients Two groups of NON-Essential nutrients 1. Alcohol does not fir in either micro or macra It has calories (7wers19) 2. phytonutrients Kcals vs calories: 1.Carbohydrates AMDR: 45-65% Calories are a synonym for Kcals. Kois means kilocajerie or 1000 grames Our body prefers to use carbonyarates (glucose) and far (Fatty acids) for energy They are preferred sources of energy Some tissues/cells omy use glucose for energy. Our Nervous system tossuc lon and Red blood cells only use glucose for enugy ما However, our muscles can use glucose, fats and prerans as a source of energy eur body uses protein as a secondary source of energy. * we use more FATS at lower intensity exerciso * we use more CARBS at higher intensity exercise CATEGORIES OF CARBOHYDRATES 1. Simple carbohydrates: monosaccharides & disaccharides (sugars) 2. Complex carbonyarates starches & fiber Monosaccharides. Disaccharides CHIC Bucruse (gusme an 다 know all Mono & aisacchandes Glucose Fructose monosaccharides are composed on one sugar and are the basic building block of ALL CHO'S. OH CHIM Galactose Lactose Igelaclase gucose) Maltese Module 2 1/14/21 Starches are large molecules Composed entirely of glucose bonded together and are storage molecules of glucose in plants. Starch Glucose molecules Starch Fiber is also a large molecule composed entirely of glucose bondea together. They are structural components of plant rather than storage form of glucose. جا Difference between Starch and Fiber is that the bonds between glucose in fiber is different than starch and we cannot digest the bonds in fiber Digestion: We CAN digest disaccharides and starch because we have the enzymes We CANNOT digest fiber because we don't have the enzymes to digest them. we DON'T digest monusaccharides, we absorb them as is. Digestion The process of breaking our food down to the smallest murrionts that then get absorbed Absorption The process of transporting the smallest nutrients from our 61 tract into our blood for use by our body. monosaccharides are the only carbohydrate that can be absorbed 2. FATS AMDR 20-36 ALL lipids are fat soluble they get along with four 1. Fats fats are lipids that have calories 2. Cholesterol lipids that do NOT have calories * fatty acids are the building blocks of fats * Cholesterol is a non-essential dietary lipid. ما Does not have to be digested to be absorbed ما we make it, thus why its non-essential Has no calories Fats in our diet: 1. Fatty acids the building blocks of all FATS 2. Triglycerides: A molecule in our avet that is composed of 3 fatty acids bonded to glycerol G Farty sua i Fartu ada * most of our dietary fat comes from triglycerides *
