  13. 13. Healthy diet• A healthy diet is one that helps maintain or improve general health. It is important for lowering many chronic health risks. A balanced diet must contain carbohydrate, protein, fat, vitamins, mineral salts.It must contain these things in the correct proportions.
  14. 14. Balanced diet 02/01/2012A balanced diet should contain fats, proteins andcarbohydrates in roughly these amounts: Carbohydrates Fat ProteinIt should also contain water, vitamins, minerals .
  15. 15. Carbohydrates
  16. 16. Carbohydrates• These provide a source of energy.• We obtain most of our carbohydrate in the form of starch. This is found in potato, rice, spaghetti, yams, bread and cereals. Our digestive system turns all this starch into another carbohydrate called glucose. Glucose is used by our tissues as a source of energy.
  17. 17. Proteins
  18. 18. Proteins• Proteins are required for growth and repair.Proteins are very large molecules, so they cannot get directly into our blood; they must be turned into amino-acids by the digestive system. Our cells get their amino-acids from the blood.
  19. 19. FatsFOOD
  20. 20. FAT• Fats are used as a source of energy: they are also stored beneath the skin helping to insulate us against the cold. Do not think that by avoiding fat in your diet you will stay thin and elegant• You must have some fat in your diet because it contains fat soluble vitamins.
  21. 21. Vitamins
  22. 22. Vitamins Vitamin A: good for your eyes. Vitamin B: about 12 different chemicals. Vitamin C: needed for your body to repair itself. Vitamin D: can be made in your skin, needed for absorption of Calcium. Vitamin E: the nice one - reproduction
  23. 23. Poor diets 02/01/2012If we don’t have a balanced diet we may suffer form a“deficiency symptom”: Lack of… Causes… Vitamin D Anaemia Protein Scurvy (bleeding gums and joints) Vitamin C Weak bones and teeth Vitamin A Wasting of body tissue Iron Rickets Calcium Poor night vision
  24. 24. HAEMOGLOBINA drop of blood contains millions of red blood cells,or erythrocytes. These specialised cells are likeflattened discs, which gives them a much greatersurface area with which to exchange oxygen andcarbon dioxide in the lungs and with body cells.Red blood cells are able to carry oxygen soefficiently because of a special protein inside them:haemoglobin. In fact, it is the haemoglobin that isresponsible for the colour of the red blood cell.Haemoglobin contains an iron atom at its centre.
  25. 25. Illness• Rickets is a disease of growing bone due to deficiency of vitamin D, magnesium.
  26. 26. Scurvy• Scurvy is a condition where an individual has a vitamin C (ascorbic acid) deficiency. The name scurvy comes from the Latin scorbutus, and humans have known about the disease since ancient Greek and Egyptian times.
