DIET
GCSE PE YEAR 10
Maintaining a balanced diet
PROTEINS
these are commonly known as "building blocks" because they are very important in the growth of new tissue. The two main sources of protein are animal products and plant foods, such as beans, lentils, nuts and seeds.

Dietary considerations
No single food is able to provide all the nutrients the body needs so it is important to eat a variety of foods. There are five main food groups:
bread, rice, potatoes, pasta and other starchy foods
fruit and vegetables
milk and dairy foods
meat, fish, eggs, beans and other non-dairy sources of protein
food and drink high in fat/or sugar
Failing to maintain this balance it could result in following dietary imbalance and deficiencies:

Malnutrition- this is a physical weakness resulting from insufficient food or an unbalanced diet.

Obesity- this is a condition of being extremely fat or overweight, which frequently results in health problems.

Anorexia- this is an eating disorder primarily occurring in girls and women, related in fear gaining weight, in self-starvation and distorted

body image.
There may be particular occasions when a diet may need to be adjusted or even adapted for particular performer and particular activities.
Eating food is necessary to provide the body with energy. Eating right food will ensure that you have enough energy and that you are also able to maintain the correct body weight for you particular needs.
Energy is needed by the body even when it is at rest, but as soon as you become more active your
basal metabolic rate
is affected and you will need to balance the requirements your body has taken in with the amounts that are being used up.
Everyone needs a food in order to survive.

The
nutrients
(
the substances that make up the food
) in food are:

CARBOHYDRATES
These are separated into
simple
and
complex
carbohydrates.

Simple carbohydrates
, or sugars, include glucose and sugar.

Complex carbohydrates
, or starches, include pasta, bread and rice. Carbohydrates are one of the main source of energy and are essential for active people.



The eatwell plate makes healthy eating easier to understand by giving a visual representation of the types and proportions of foods needed for a healthy and well balanced diet.
Eatwell Plate
WATER/FLUIDS
These are absolutely essential because failure to replace lost water can result in
dehydration (the rapid loss of water from the body)
. More problems can be caused by lack of water then by lack of food.
FIBER/ROUGHAGE
this is important as an aid to the digestive system and it is contained in cereals, wholegrain bread and oats
Activity
Looking at the Eatwell Plate write down your typical day food consumption from the morning till the last meal in the evening. Do you eat well?
5 minutes
MALNUTRITION
ANOREXIA
OBESITY
Specific diets
Lesson objectives:

1. Consider how diet is linked to the levels of activity of individuals
2. Consider the correct and appropriate times for food to be eaten
3. Consider special diets that particular types of performers might require or use
The number of
calories
needs to balance because if you have a higher intake than output you will tend to put on weight and if you are very active you will need to make sure that you are providing your body adequately.
When to eat is also a factor you need to consider carefully. The basic guidelines for this are:

Before Activity
-do not eat too close to performing.Try to wait about two hours after eating.

During activity
-generally you should not eat during activity but something light and in small quantities, such as a banana, would be fine.

After activity
- you should try to leave the same two-hour gap as you did before activity.
Liquids

may need to be taken before, during and after the activity to avoid dehydration, but do not take in too much liquid immediately after finishing as this can result in discomfort.
Carbohydrate loading
This is particular dietary plan that endurance athletes, mainly marathon runners, use involving eating plenty of starch-rich foods, such as pasta, in the week before an important competition or event. The starch increases the amount of
GLYCOGEN
in the muscle, which can help to delay tiredness and can improve performance in the end stages of s competition because it is slow-release form of energy.
High-protein diets
These diets are often used by bodybuilders as a mean of building muscle and losing fat. However, it must be remembered that extra protein in itself does not add muscle and high protein food can be difficult to digest so they should not be eaten just before training or competing. (recovery time after injury)
How is your maths? Can you quickly calculate amount of water you need during your normal day?
HOMEWORK

Sports diet is one of the most important factor which optimize athlete`s performance and to give them the best possible results.

On a piece of A4 paper, design a healthy and balanced diet poster/chart for your sporting idol.
Write the paragraph (min 250 words) on how you could improve your dietary habits. write what do you need to change in your daily diet to enhance your sporting performance.
Revise for end of chapter 3/4 test.





A personal concept of your own physical appearance
The minimum rate of energy required to keep all of the life process of the body maintained when it is at rest.
A unit that measure heat or energy production in the body.
LESSON OBJECTIVES

Be aware of what constitutes a balanced diet in terms of nutrients required.
Be aware of the different food types and nutrients they contain.
Consider what proportions of food should be consumed to ensure balanced diet.
Consider the problems that could be caused by imbalance or deficiency in diet.
FATS
There are three types of fats and they are commonly found in cheese, cream, meat, cooking oils, margarine and butter. Fats are a major source of energy for the body.
VITAMINS
essential to enable you to maintain good health, vitamins are only required in small quantities and are usually contained in a normal diet.
Everyone should try to choose different foods from the first 4 groups every day. Foods from the fifth group are not essential to a healthy diet.
