Aerobic Endurance Exercise Training Unit 5 – Improving Health and Fitness for Entry to the Uniformed Public Services Session 6 The Effects of Basic Nutrition Staff Cunliffe
3
Session AIMS To Introduce students to the effects of basic Nutrition and the different food groups. Prepare students to be able to record a personal food diary.
4
Objectives By the end of this session students will be able to: List the basic seven food groups. Identify food sources for each of the seven food groups Describe the importance of each food group.
5
What Is Nutrition? Nutrition is the process of how the body intakes and utilises foods and nutrients vital to health in promoting growth, maintenance and reproduction cells. What we eat and drink affects our health. There are seven essential food groups our body needs.

www.A6training.co.uk Activity 1 - Knowledge Probe In pairs list as many of the seven essential food groups as you can on the post it notes provided? You have thirty seconds End
7
The Seven Essential Food Groups Protein Carbohydrates - Complex Carbohydrates - Simple Carbohydrates Fats - Saturated Fats - Unsaturated Fats Water Fibre Vitamins Minerals

10
Protein The digestive system breaks down protein in foods we eat Absorbed into the bloodstream for growth and repair (White blood cells) Recommended Dietary Intake = 15% Increase to 30% for high muscular strength and endurance training 1 gram of protein = 4 calories
11
Protein Food Sources Fish White Meat Quorn/ Torfu Milk Eggs Pulses (chick peas/ beans)
12
Carbohydrates Divided into complex carbohydrates and simple carbohydrates (sugars = glucose) The digestive system absorbs carbohydrates into transports them to cells throughout the body Provides cells with power/ energy: Simple carbohydrates = instance energy release Complex carbohydrates = slow energy release Excess sugar is stored in the liver When liver stores are full, it is stored at fat
13
Carbohydrates When exercising for short periods, liver stored will be used for energy. When exercising for long periods, fat will be used for energy. Recommended Dietary Intake = 55% Increased to 60-70% for high cardiovascular training 1 gram of Carbohydrates = 4 Calories
14
Carbohydrate Food Sources Complex Carbohydrates: Bread Pasta Rice Potatoes Cereal Simple Carbohydrates: Sweets Chocolate Cakes Fruit Jam
15
Fats Fats are essential for insulation and to protect vital organs Major source of energy in the body - broken down and used in muscles for fuel Excess fat is stored Fats can be divided into saturated fat and unsaturated fat Saturated fats can come from animal or vegetable products - clog the arteries Unsaturated fats come from plants, seeds or fish - help lower cholesterol
16
Fats When exercising for long periods, fat will be used for energy. Recommended Dietary Intake = 30% 40-50g Reduced to 15-30% when training 1 Gram of fat = 9 Calories
17
Fat Food Sources Saturated Fat: Biscuits/ Cakes/ Pastries Butter Egg Crisp Burgers Kebabs Chips Red Meat Unsaturated Fat: Nuts Olive/ Sunflower oil Sesame/ pumpkin seeds Fish Avocado
18
Water 80% of the body is Water Water is lost through respiration, sweating and urine Approximately one litre per day is lost Dehydration can reduce attention span and cause headaches/ Irritability During exercise can cause dizzy spells, reduced performance and fainting Recommended Daily Intake = 8 glasses/ 2 litres Page 86
19
Fibre Fibre is absorbed in the digestive system to get rid of waste products Absorbs water to make waste disposal more efficient Protect against high cholesterol heart disease and bowel cancer Suggested Recommendations = 18-30g daily or 1/3 of dietary intake
20
Fibre Food Sources Lentils Brown rice, bread and pasta Fruit and Vegetables Beans (Kidney beans, chick peas) Whole Grain cereals
21
Vitamins Supports growth and repair of bones, teeth and skin Assist in chemical reactions – converting food into energy
22
Vitamins Vitamin A - Maintains health of the eye Sources – Carrots, sweet potato and spinach Vitamin B(s) - Converts food sources to energy and maintains digestion Sources – Variety of Carbohydrates, fats and proteins Vitamin C – Growth and repair of skin, bones, teeth. Helps immune system fight infections and viruses Sources – Fruit and Vegetable (Oranges and Lemons) Vitamin D – Absorbs calcium to maintain healthy bones and joints. Sources – Sunlight, fish, milk and egg yolk.
23
Minerals Growth and repair of skin, bones, teeth and production of tissues/ muscle fibres Assist in chemical reactions - transportation of fats and absorption of vitamins
24
Minerals Calcium – Bone formation Sources – Green vegetables, nuts, milk and cheese Iron – Production of red blood cells Sources – Red meat, beans and green vegetables Phosphorus - Strengthens bones and teeth Sources – Dairy products, bread, red meat/ poultry Potassium and sodium – Responsible for nerve impulses, controls blood pressure Sources – Salt, fruit and vegetables
25
Objectives By the end of this session students will be able to: List the basic seven food groups. Identify food sources for each of the seven food groups Describe the effects and importance of each food group.
