  19. What is an example of visible fat?

  20. What is an example of visible fat? • Fat on Meat • It's white and you can see it!! • Chicken skin

  21. The body’s main source of energy What nutrient is?

  22. CARBOHYDRATESThe body’s main source of energy

  23. What are the 2 types of Carbohydrates?

  24. What are the 2 types of Carbohydrates? • Simple • Complex

  25. Complex CARBOHYDRATES starches like potatoes & grain products dietary fibre = non-digestible plant sources like fruits & veggies *Soluble Fibre *Insoluble Fibre - dissolves in water - doesn’t dissolve in water - increases thickness of - absorbs water like a sponge, stomach contents helps large intestine digest food - fruits, veggies, legumes, oats - fruit & veggie skins, whole wheat/bran

  26. Simple Carbohydrates • Come from what? • S_______ • What are some examples?

  27. Simple Carbohydrates sugars which contain nutrients like fructose [from fruits], maltose [from grains products], lactose [from milk products] sugars which contain no nutrients like sucrose [refined sugar from plants like sugar cane]

  28. What nutrient? • Helps the body grow/repair itself, regulate bodily processes & act as a source of energy

  29. Protein • Help the body grow/repair itself, regulate bodily processes & act as a source of energy

  30. PROTEINS Can only do their jobs in conjunction with carbohydrates & fats Found in animal & plant sources; *Animal *Plant - meat, fish, poultry, eggs - legumes, peanuts, grains

  35. COMPLETE PROTEINS Complete Proteins = supply the body with all 9 essential amino acids e.g., meat, fish, poultry, eggs & soy products

  36. INCOMPLETE PROTEINS Incomplete Proteins = contain 8 or less essential amino acids e.g., legumes, peanuts, grains The body makes 22 of the 31 amino acids, the body needs to get the other 9 from food sources
