7 Aspects of a Balanced Diet Carbohydrates provide us with energy 2 types Complex Known as Starch, found in natural foods such as; bananas, brown rice, whole meal bread and potatoes Simple These are also known as sugars. They can be found in fruit and vegetables.
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

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?
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

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

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
