FATS

WHAT FOODS PROVIDE US WITH FAT?

PROTEIN Protein is important to help build muscles and repair damaged tissue. 2 MAIN SOURCES Animal products Plant foods (meat & fish) (beans, lentils, nuts)

MINERALS Minerals are required in small amounts. VITAMINS Essential to enable you to maintain good health – required only in small quantities. They are usually contained in a normal diet. Vegetables & Meats Red Blood Cell Formation Blood Clotting Good Vision Healing Good Skin Healthy Bones

Absolutely essential – if fail to replace lost water then it can result in DEHYDRATION. More problems can be caused by a lack of water than a lack of food WATER

FIBRE Without fibre our body would not get rid of waste Important as it aids the digestive system

Test yourself FILL IN THE QUESTIONS ON YOUR OWN TO SEE WHAT YOU HAVE LEARNT SO FAR….. CAN YOU HIT YOUR TARGET GRADE OR ABOVE?

Grades A* - 87% A – 81% B – 75% C – 70% D – 58% E – 47%

DIETERY CONSIDERATIONS No single food can provide all the nutrients that the body needs We should aim to eat four of the groups everyday – which group is not essential for a healthy diet?

Balanced diet- proportions

Failure to lead a healthy diet could result in….

MALNUTRITION A physical weakness resulting from insufficient food or an unbalanced diet OBESITY A condition of being extremely fat or overweight – frequently results in health problems ANOREXIA An eating disorder primarily occurring in girls/women

In pairs take it in turns to answer the questions - build on one another’s answers if you can!! Together can you get 9/9? PROGRESS REVIEW

1.Name the 5 food groups 2.Name the 7 nutrients that are in our food? 3.What is dehydration 4.What is obesity and why is this bad for a persons health? 5.What does protein do? 6.What are nutrients? 7.Give an example of food that is high in fibre. 8.What proportions of food should we eat most of in a day for a healthy diet? 9.Which food group do we not need to eat for a healthy diet? 10.What are the two types of carbohydrates? WHAT HAVE YOU LEARNT??

Eating the right foods will ensure you have enough energy for your particular needs & keep you at the correct body weight

Who needs more energy?? A B

Arguable who needs more BUT they do both need a balanced diet & will need different energy requirements

BASAL METABOLIC RATE– minimum rate of energy required to keep all of the life processes of the body maintained when it is at rest. We need to balance what our body is taken in with the amounts being used. Too much calorie intake and not enough output = weight gain If you are really active you will need to ensure your providing your body adequately We use energy when our body is at rest but as soon as become more active your BASIL METABOLIC RATE is affected.

BEFORE – Try to wait about two hours after eating DURING ACTIVITY – Generally you should not eat during activity but something light & small quantities would be fine AFTER – Try to wait the same two hour gap What about liquids?

t8 Who? What? Why? In pairs pick one of the specific diets – research it (p53) and then teach your partner – BOTH take notes

It is designed to make maximum use of the athletes energy resources  Athlete eats plenty of starch rich foods in the week leading up to an event.  The starch increases the amount of glycogen in the muscles which can help delay tiredness & can improve performance in the end stages as it is a slow-release form of energy

 Often used by body builders as a means of building muscle and loosing fat  HOWEVER – extra protein in itself does not add muscle AND high protein foods can be difficult to digest. SO DON’T EAT BEFORE TRAINING OR COMPETITIONS

 Write down 2 questions  You will then be picked at random to be asked
