  3. Carbohydrates (cont) • better to get simple sugars from fruits and milk. • pancreas releases a hormone called insulin when you eat sugar • turns into simple sugars • Helps to break down foods

  4. Fats Examples of edible animal fats -lard, fish oil, butter or ghee Examples of edible animal fats -peanut, soya bean, sunflower, sesame, coconut, olive, and oils Can be sorted into saturated fats & unsaturated fats. Are foods that are made up of carbon, hydrogen, oxygen

  5. Fats(cont) • All fats have chains of fatty acids • Fats help in maintaining • healthy skin/hair, • body organs, • body temperature, • healthy cell function. • energy stores for the body

  6. Proteins • Some fold into structure with small holes • -Are enzymes that help “biochemical” reactions -Are helpful to metabolism -Are important in cell signalling - immune responses -cell adhesion -cell cycle.

  7. Protein (cont.) • Are parts of organisms and process within cells • Has its own amino acid • people who eat vegetarian can still get protein-rich foods. • Examples • -meat ,grains, dairy ,nuts.

  8. Fibre • Soluble fibre absorbs water • gelatinous, is cloaked by bacteria in the digestive tract. • Insoluble fibre is not fermented. • major dietary insoluble fibre source. • lignin may alter metabolism of soluble fibres.

  10. Vitamins • Helps body grow and develop -need for health, growth and reproduction • Examples, dairy, fruits, vegetables • Two types, fat soluble and water soluble -originally placed in categories based on function in body

  11. Vitamins (Cont) • An organic compound required as a nutrient in tiny amounts by an organism • Thirteen different types -vitamin D in milk helps your bones -vitamin A in carrots helps you see at night -vitamin C in oranges helps your body heal if you get a cut -vitamin B in leafy green vegetables helps body make protein and energy

  14. Minerals (Cont) • Two types macro minerals and trace minerals • Is a substance that is neither animal nor vegetable; inorganic matter • Your body needs larger amounts of some, such as calcium to grow and stay healthy -calcium would be a macro mineral, because it is a larger amount

  15. Minerals (Cont) • Trace minerals includes iron, manganese, copper, iodine, zinc, cobalt, fluoride and selenium -trace mineral means you need small amounts of each of these minerals a day

  16. Water • Is essential for people and nature • Examples are most fruits and vegetables and some dairy products • Freshwater faces crises -including contamination and shortages • Is a clear colorless tasteless odourless liquid • Two types, fresh and salt
