  1. Nutrition By: Danny Liu Block 2~

  2. Carbohydrates • sugars and starches that provide energy • types: - simple(sugar): fruits, milk, and vegetable, cake, candy, and other refined sugar - complex: rice, pasta, and starchy vegetables. Provide vitamins, minerals, and fibre • contain carbon, oxygen and hydrogen • monomers joined by glycoside bond to form disaccharide • fuel the body, help getting through the day • get hungry fast If you eat simple carbohydrates • not be hungry if you eat complex carbohydrates

  3. Fats • made up of carbon, hydrogen, and oxygen • come in liquid or solid form • source of energy in foods • types: - saturated fats: butter, cheese, whole milk, ice cream, cream, and fatty meats, and oils such as coconut, palm, and palm Kemal oil - trans-fatty acids: fried foods, commercial baked goods, processed foods and margarine • contain nutrients that provide energy the body needs • needed for absorption of fat-soluble vitamins A, D, E and K • one of the three nutrients with protein and carbohydrates

  4. Protein • contain carbon, hydrogen, oxygen, nitrogen, and usually sulphur • build up, keep up, and replace the tissues in your body • primary component of numerous body tissues • fundamental components of all living cells • foods have high protein: -Eggs, milk, meat, apricots, avocados, bananas, cherries, dates, figs, nuts, beans, and grapes. • high protein diets can be dangerous if not done properly • it can worsen the symptoms of liver and kidney disease

  5. Fibre • virtually indigestible substance that found outside the layers of plants • type of carbohydrate that passes through the human digestive system • food have fibre: -All-natural cereals, whole-grain breads, beans, fruits, vegetables, nuts • broken down in colon(main part of large intestine) • makes food more satisfying, probably • main fibre is to keep digestive system healthy • helps the digestive process and is thought to lower cholesterol

  6. Vitamins • substances are found in foods we eat • needs them to work properly • can be used over and over • essential in the diet because the body doesn’t produce enough • types: - Vitamins A: eggs, meat and dairy products. Come from green, leafy vegetables and intensely colored fruits and vegetables - Vitamins B: fortified breads and cereals, fish, lean meat and milk - Vitamins C: citrus fruits, green peppers, strawberries, tomatoes, broccoli and sweet and white potatoes - Vitamins D: cheese, butter, margarine, fortified milk, fish, and fortified cereals - Vitamins K: cabbage, cauliflower, spinach and other green, leafy vegetables, as well as cereals • any of a group of organic substances essential in small quantities to normal metabolism

  7. Minerals (dietary) • help your body grow, develop, and stay healthy • just like vitamins • types: - macro minerals: calcium, phosphorus, magnesium, sodium, potassium, chloride, and sulfur - trace minerals: iron, manganese, copper, iodine, zinc, cobalt, fluoride, and selenium • perform many different functions • building strong bones to transmitting nerve impulses • used to make hormones • maintain a normal heartbeat

  8. Water • water = H2O • not a nutrient but it’s necessary for life • there are 10 different types of water • transports nutrients and wastes • also for many chemical reactions • also for cooling the body through perspiration • requires 3 to 5L of water each day
