4 WHAT IS BALANCED DIET? A BALANCED DIET MUST CONTAIN CARBOHYDRATE, PROTEIN, FAT, VITAMINS, MINERAL SALTS AND FIBRES. IT MUST CONTAIN THESE THINGS IN APPROPRIATE PROPORTIONS. COMPOSITION OF BALANCED DIET. CARBOHYDRATES PROTEINS FATS VITAMINS

5 CARBOHYDRATES. CARBOHYDRATES ARE THE MOST IMPORTANT SOURCE OF ENERGY. THEY CONTAIN ELEMENTS LIKE CARBON, HYDROGEN AND OXYGEN. THE FIRST PART OF THE NAME CARBO- MEANS THAT THEY CONTAIN CARBON THE SECOND PART OF THE NAME HYDR- MEANS THAT THEY CONTAIN HYDROGEN. THE THIRD PART OF THE NAME ATE- MEANS THAT THEY CONTAIN OXYGEN.

6 PROTEINS. PROTEINS ARE REQUIRED FOR GROWTH AND REPAIR. PROTEINS CONTAIN CARBON, HYDROGEN, OXYGEN, NITROGEN AND SOMETIMES SULPHUR. PROTEINS ARE VERY LARGE MOLECULES, SO THEY CANNOT GET DIRECTLY INTO OUR BLOOD; THEY MUST BE TURNED INTO AMINO-ACIDS BY THE DIGESTIVE SYSTEM. THERE ARE OVER 20 DIFFERENT AMINO-ACIDS. OUR BODIES CAN TURN THE AMINO-ACIDS BACK INTO PROTEIN. WHEN OUR CELLS DO THIS THEY HAVE TO PUT THE AMINO-ACIDS TOGETHER IN THE CORRECT ORDER. THERE ARE MANY MILLIONS OF POSSIBLE COMBINATIONS OR SEQUENCES OF AMINO-ACIDS; IT IS OUR DNA WHICH CONTAINS THE INFORMATION ABOUT HOW TO MAKE PROTEINS. OUR CELLS GET THEIR AMINO-ACIDS FROM THE BLOOD.

7 FATS. LIKE CARBOHYDRATES, FATS CONTAIN THE ELEMENTS CARBON, HYDROGEN AND OXYGEN. 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! IF YOU EAT TOO MUCH CARBOHYDRATE AND PROTEIN, YOU WILL CONVERT SOME OF IT INTO FAT, SO YOU WILL PUT ON WEIGHT. YOU MUST BALANCE THE AMOUNT OF ENERGY CONTAINING FOODS WITH THE AMOUNT OF ENERGY THAT YOU USE WHEN YOU TAKE EXERCISE.

8 VITAMINS. VITAMINS ARE ONLY REQUIRED IN VERY SMALL QUANTITIES. THERE IS NO CHEMICAL SIMILARITY BETWEEN THESE CHEMICALS; THE SIMILARITY BETWEEN THEM IS ENTIRELY BIOLOGICAL. 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?

9 MINERAL SALTS. THESE ARE ALSO NEEDED IN SMALL QUANTITIES, BUT WE NEED MORE OF THESE THAN WE NEED OF VITAMINS. IRON: REQUIRED TO MAKE HAEMOGLOBIN. CALCIUM: REQUIRED FOR HEALTHY TEETH, BONES AND MUSCLES. SODIUM: ALL CELLS NEED THIS, ESPECIALLY NERVE CELLS. IODINE: USED TO MAKE A HORMONE CALLED THYROXIN.

10 FIBRE. THIS IS A CARBOHYDRATE USED BY PLANTS TO MAKE THEIR CELL WALLS. IT IS ALSO CALLED ROUGHAGE. IF YOU DO NOT EAT FOODS MATERIALS WHICH CONTAIN FIBRE YOU MIGHT END UP WITH PROBLEMS OF THE COLON AND RECTUM. THE MUSCLES OF YOU DIGESTIVE SYSTEM MIX FOOD WITH THE DIGESTIVE JUICES AND PUSH FOOD ALONG THE INTESTINES BY PERISTALSIS; IF THERE IS NO FIBRE IN YOUR DIET THESE MOVEMENTS CANNOT WORK PROPERLY.

12 CONSUMPTION OF FOOD BY DIFFERENT GROUPS. ALL AGE GROUPS NEED DIFFERENT QUANTITY OF DIET. DIET VARIES ON AGE OF THE PERSON AND THE WORK HE /SHE DOES TO EARN HIS LIVELIHOOD. AGE: TEENAGER NEEDS MUCH MORE FOOD THAN THE OLDER PEOPLE. TEENAGERS NEED FOOD TO GET ENERGY AND WARMTH. THEY NEED IT FOR ALL ROUND DEVELOPMENT OF THEIR BODY. THEY ALSO REQUIRE PROTEIN IN LARGER QUANTITY. OLDER PEOPLE NEED MUCH SMALLER QUANTITY OF FOOD THAN TEENAGERS.

13 SEX: MEN NEED MUCH QUANTITY OF FOOD THAN WOMEN. THEY NEED IT BECAUSE THEY HAVE TO DO HARD WORK TO EARN THEIR LIVELIHOOD. CLIMATE: IT HAS A MAJOR EFFECT ON FOOD CONSTITUENTS. PEOPLE LIVING IN COLDER AREAS NEED MUCH QUANTITY OF FOOD MATERIALS THAN PEOPLE LIVING IN HOTTER AREAS. HARD WORKING: IT VARIES FROM PERSON TO PERSON. THOSE PEOPLE WHO DO MUCH WORK NEED A MORE QUANTITY OF FOOD. THE REASON IS THEY HAVE TO SPEND MUCH ENERGY ON THEIR HARD WORK. PEOPLE WORKING HARD MUST CONSUME FOOD CONTAINING MUCH AMOUNT OF CARBOHYDRATES.
