In February, you will decide whether you The things you learn this year WILL come up want to pick separate in your real exams at the end of Y11! sciences or coordinated sciences So...this year is very important! IGCSE CIE Layout Time for Biology What will we be studying this year? Balanced diets unbalanced diets Diseases Food groups Digestive system Enzymes Biochemistry Starter Why is food important for humans? Decode the Pictures Learning Objectives State the different food groups required in the diet Give examples of foods containing the different food groups Describe the roles of the main food groups in the body Syllabus statements 1. What are the 7 major food groups? 2. Why are proteins important in the diet? 3. What foods contain carbohydrates? 4. Which food group is not digested by the body? 5. Is iron a vitamin or a mineral? Why is it needed in the diet? 6. Why are fats needed in the diet? 7. Why are carbohydrates needed in the diet? 8. What is constipation? The 7 food groups Our bodies require 7 different food groups to stay healthy. We must make sure our diet contains the correct amount of each of the following: - Carbohydrates - Proteins - Fats - Vitamins - Minerals - Fibre - Water Carbohydrates Source of energy, for example glucose is important for respiration.  Proteins are important for the Proteins growth and repair of cells/tissues. They are also important for hormones, enzymes and antibodies. Fats/ Lipids Fats/lipids can be used as a source of energy and insulation. Fibre Fibre cannot be digested by the body. It is made up of plant cell walls (cellulose). It is very important for encouraging a smooth passage of food through the Alimentary canal in the digestive system – otherwise we get constipation! Vitamins Essential for the body to be able to use other nutrients efficiently. Only needed in small amounts. Vitamin C Vitamin D Minerals Essential for the body to be able to use other nutrients efficiently. Only needed in small amounts. Iron Calcium Water Essential for hydration and metabolic reactions. Component Function Source Carbohydrates Provides energy Potatoes, bread, rice, pasta Proteins Growth and repair of cells and tissues fish, meat, eggs, pulses and beans Fats/lipids Insulation and long term store of energy Oils, butter Vitamins Vitamin C helps make collagen in skin and nails. Vitamin C: fruits and veg Eg Vitamin C + D Vitamin D helps you to absorb calcium Vitamin D: oily fish Minerals iron: helps with transport of oxygen around the body (haemoglobin). iron: red meat and spinach Eg iron and calcium calcium: Makes teeth and bones strong. calcium: milk, yogurt, cream Fibre Prevents constipation and colon cancer Wholewheat pasta, fruits and (ROUGHAGE) vegetables Water Assists with chemical reactions in the body Fruits and veg, soup  Miss Sesay’s daily meal What food groups are present in my daily meal?: Breakfast: Porridge, milk Lunch: Spinach and feta Dinner: Noodles, prawns and honey. cheese sandwich. and stir fry vegetables Task 1 -meal plan Write down on average what you eat for: Breakfast Lunch Dinner Identify the food groups within your meals.
