  1. 1. Nutrition Provide Support to meet Personal Care Needs CHCICS301A Updated by Jo Lewis BHS
  2. 2. What is nutrition? <ul><li>Nutrition = all processes by which the body utilises food and fluids for energy, growth and maintenance </li></ul><ul><li>At all stages of the lifespan, we need good nutrition, to resist illness, repair tissue, regulate body functions and provide energy </li></ul>
  3. 3. Characteristics of Nutrition
  4. 4. Nutritional requirements <ul><li>Nutritional requirements are considered in terms of essential and balanced nutrients (ie protein, fats, carbohydrates, vitamins etc), and energy (kilojoules) </li></ul><ul><li>Need foods from each of the basic food groups, in sufficient quantities (milk/dairy, meat/fish/eggs, fruit and veg, breads and cereals, fats, water) </li></ul>
  5. 5. How should nutrients be distributed ?? <ul><li>Traditional model = Healthy Diet Pyramid </li></ul><ul><li>Other distributions ie diet consisting of 60% carbohydrate, 20% protein, and 20% fat often thought appropriate </li></ul><ul><li>Current trend towards lower carbohydrate and higher protein intake </li></ul><ul><li>Important to eat a variety of foods each day </li></ul><ul><li>Energy requirements – don’t need as much energy in older age as there is little growth </li></ul>
  6. 7. Compare - Nutrient Requirements <ul><li>Younger adults (up to 65) </li></ul><ul><li>1 serve meat, fish, eggs, legumes = 60-75gm </li></ul><ul><ul><li>3 serves red meat </li></ul></ul><ul><ul><li>2 serves fish </li></ul></ul><ul><ul><li>1 serve chicken/pork </li></ul></ul><ul><ul><li>1 serve legumes </li></ul></ul><ul><li>2-3 serves diary foods </li></ul><ul><li>2-3 serves fruit </li></ul><ul><li>4-5 serves vegetables </li></ul><ul><li>5 or more serves bread & cereals </li></ul><ul><li>2 extras (indulgences) </li></ul><ul><li>5 or more cups of fluids </li></ul><ul><li>Frail older adults </li></ul><ul><li>2 serves meat, fish, eggs, legumes = 120-150gm/day </li></ul><ul><li>3-4 serves dairy foods </li></ul><ul><li>2-3 serves fruit </li></ul><ul><li>4-5 serves vegetables </li></ul><ul><li>5 or more serves bread & cereals </li></ul><ul><li>2 extras (indulgences) </li></ul><ul><li>5 or more cups of fluid-includes milk, soups as well as tea, coffee & other drinks </li></ul>
  7. 8. Nutrients <ul><li>The essential nutrients are: </li></ul><ul><li>Carbohydrates Water </li></ul><ul><li>Fibre Vitamins and minerals </li></ul><ul><li>Proteins Proteins </li></ul><ul><li>Lipids (fats) </li></ul><ul><li>Nutrients are the chemical substances in food that provide energy, build and maintain cells and regulate body processes </li></ul>
  8. 9. Carbohydrates <ul><li>Provide energy </li></ul><ul><li>Before being used are converted from food we’ve eaten into glucose </li></ul><ul><li>Also assist in metabolism of fat </li></ul><ul><li>Add bulk to intestinal contents aiding peristalsis </li></ul><ul><li>Found in vegetables, cereals and pastas, fruits, honey, milk </li></ul>
  9. 10. Proteins <ul><li>Compounds composed of amino acids </li></ul><ul><li>Proteins build and repair tissue, or supply energy </li></ul><ul><li>Major sources of protein are meat, fish, eggs, cheese, milk, poultry, lentils, legumes and nuts </li></ul>
  10. 11. Lipids <ul><li>Fat supplies energy and forms adipose tissue which supports and protects some organs </li></ul><ul><li>Adipose tissue also insulates the body to prevent heat loss and is a reserve store of fuel </li></ul><ul><li>Fats also supply the fat soluble vitamins A,D,E,K </li></ul><ul><li>Major food sources of fats are animal (meat, butter, oil, cream, egg yolk, cheese, fish oil) or vegetable (present in cocoa and oils like olive, safflower, peanut etc) </li></ul>
  11. 12. Water & Fibre <ul><li>Water obtained from food and fluid’s we eat and drink as a result of metabolism </li></ul><ul><li>Necessary for digestion, absorption and metabolism of food, to produce secretions, and maintain body fluids </li></ul><ul><li>Fibre is fibrous part of foods not digested or absorbed </li></ul><ul><li>Excreted in stool (BA) , and provides bulk </li></ul><ul><li>Thought to help in prevention of some disorders constipation, diverticular disease, gallstones, intestinal ca </li></ul>
  12. 13. Vitamins & Minerals <ul><li>Vitamins generally obtained from food we eat </li></ul><ul><li>Essential for metabolic function - either fat or water soluble </li></ul><ul><li>Minerals important in metabolism, maintenance of BP, cardiac function, and regulation of body processes ( homeostasis ) </li></ul>
  13. 14. Vitamin D <ul><li>Essential to maintain strong, healthy bones & assist prevention of fractures, along with calcium </li></ul><ul><li>In Australia 68-86% of elderly in Res. Care have low Vit D levels </li></ul><ul><li>Residents require 1-3hrs sun exposure (face & hands) every week – if unable, require supplements </li></ul><ul><li>Vitamin D is diminished by sunscreen </li></ul><ul><li>Cannot be obtained through glass </li></ul>
