Role of carbohydrates, protein, fats and vitamins/minerals Mr Pickford– Health, fitness and well-being

Learning Objectives Recall the constituents of and the recommended percentage intake of a balanced diet (4-5) Explain the role of carbohydrate, fat, protein and vitamins/minerals (6-7) Evaluate the importance of each element of a balanced diet (8-9)

Carbohydrates The main and preferred energy source for all types of exercise, of all intensities. Carbohydrates act as a source of glucose which is our main energy fuel. Two Types: Simple Carbohydrates, or sugars, including glucose, which break down quickly and provide your body with immediate energy. EG?? Complex Carbohydrates, or starches, which are released slowly by your body and are less likely to be stored as body fat. EG??

Jelly babies Pasta Banana Rice Potatoes Lucozade energy tablet Bread Other sources of carbohydrate

Fat Fat is also an energy source and helps to carry vitamins in the body, e.g. Vitamin A. It provides more energy than carbohydrate but only when exercising at a low intensity. Two Types: Saturated Fat is typically solid at room temperature. Too much = risk of developing heart disease and becoming obese. Unsaturated Fat is normally liquid at room temperature. It is much healthier than saturated fat and reduces risk of developing heart disease.

Vegetable oil Cheese Butter Onion rings Olive oil Other sources of carbohydrate

Protein Used for growth and repair of body tissues. It also has a small part to play in providing energy. For some athletes (Weightlifters) A diet rich in protein is beneficial to help them with the development and repair of muscle tissue.

Other sources of protein: EggsChickenFish Nutrition

Proteins are also needed by performers who are recovering from injury in order to repair damaged tissue. Nutrition

Minerals – Your body needs minerals to help it function. They increase the efficiency of carrying oxygen to muscles. Minerals can be found in: Calcium in milk Iron in meat Minerals are only needed in small quantities but are vital for the body. Nutrition

Vitamins – these generally contribute to the general health of an athlete. Vitamins are needed to: Resisting infection and disease Regulate chemical reactions in the body. Nutrition EG- Oranges, grapefruits, peppers

Fibre Purpose: Fibre is indigestible plant material which gives the gut something to push on helping to avoid constipation. Aids digestive system. Found in: Fresh fruit, vegetables, wholegrain cereals/bread

Diets for 2 different athletes

EQ EQ - Explain how the diet of a marathon runner and a weight lifter would differ. (4 marks) Box, line and circle Where would each mark be gained? Remember to say HOW the diet can benefit their performance!!

Where would each mark be gained? (4 marks) 2 marks for explaining weight lifters diet 2 marks for explaining marathon runners diet

Model answer – what would you give this?? A marathon runner would need high levels of carbohydrate within their diet. Complex carbohydrates such as pasta and bread would be best to eat as it would provide the runner with the slow release energy that they need for the 26 miles of the race. A weight lifter would need high levels of protein within their diet. Protein such as chicken and fish would help build and repair muscles after training. By having a high protein diet it will help the weight lifter lift a heavier weight.
