TARGET AUDIENCE • Students in the track and field, specifically discus throwers
OBJECTIVES • Analyse the dietary needs of these students in the aspect of • Age group (13 years to 16 years) • Level of activity • Specific nutrition needed • Assessing the Yong Tau Foo Stall in our school for • Nutritional value • If it is adequate for discus throwers • Design a meal for these people in these aspects: • Realistic • More balanced nutrition compared to the Yong Tau Foo Stall • Costs • Compare the designed meal to the Yong Tau Foo Stall and state its benefits
BACKGROUND RESEARCH - CARBOHYDRATES • Best fuel sources for athletes • Provides energy; initial fuel source • In short-burst, high intensity events such as sprinting, jumping as well as discus throwing, carbohydrates provide 100% of the energy • The body stores limited amounts of carbohydrates as glycogen
BACKGROUND RESEARCH - CARBOHYDRATES • Physical training and a diet rich in complex carbohydrates help athletes to store more glycogen and to use its limited supply sparingly • Complex carbohydrates come from food such as: • Spagahetti • Potatoes • Lasagna • Cereals • And other grain products • When glycogen supply runs low, athletes become fatigue and performance suffers
BACKGROUND RESEARCH - PROTEINS • Building blocks of the body • Consists of amino acids that form muscles, bones, tendons, skin, hair and other tissues • Athletes need protein primarily to repair and rebuild muscle that is broken down during exercise • Also help to optimize carbohydrate storage in the form of glycogen • Not an ideal source of fuel for exercise
BACKGROUND RESEARCH - PROTEINS • Sources of proteins: • Meat • Fish Eggs • Vegetables • Fruits • Nuts
BACKGROUND RESEARCH - FATS • Essential nutrient for optimal health • Store fat provides cushion and insulation to internal organs • Moves Vitamins throughout the body • Largest reserve of store energy available for activity
BACKGROUND RESEARCH - FATS • Types of dietary fats • Saturated fats (Too much of these may cause health problems) • Meat • Egg yolks • Yoghurt • Cheese • Butter Milk • Unsaturated fats • Usually found in plant food sources • Brings health benefits • Athletes should aim to eat more food containing more unsaturated fats
BACKGROUND RESEARCH - MINERALS & VITAMINS • Minerals • Inorganic elements that aid in the formation of strong bones • Cannot be made by the body; they are provided by the food we eat • Vitamins • Organic compounds that help regulate fat, carbohydrate and protein metabolism in the body • Cannot be made by the body; they are provided by the food we eat • Not an energy source, but play a vital role in releasing energy stored
DIETARY NEEDS • High carbohydrate intake to cope with training load • About 1.4-2.0 grams of carbohydrates per kg of body weight • Normal intake of proteins • About 1.4-1.8 grams of proteins per kg of body weight • Normal intake of fats as well • High intake of vitamins and minerals • Athletes should take in as much vitamins and minerals as possible
PROPOSED MEAL • Yong Tau Foo allows individuals to order the ingredients he wants • Added in other kinds of food such as drinks to complement the needs of the discus thrower • Emphasis on carbohydrates and vitamins • Carbohydrates – main source of energy • Vitamins – aid in releasing of energy
PROPOSED MEAL • Orange/ Watermelon Juice (Optional) • Source of vitamins • Bee Hoon • Main source of carbohydrates • Laksa Soup • May be unhealthy, but provides both carbohydrates and vitamins • Dry Shrimp Dumpling • Source of carbohydrates • Chinese Sausage • Source of carbohydrates • Chocolates (Optional) • High source of carbohydrates
PROPOSED MEAL • Total costs • $1.50 + $0.50= $2.00(Without Orange Juice and Chocolates)4 ingredients: $1.50Bee Hoon: $0.50Orange Juice: $1.00-$1.50
