What food source can you find HBV the most. Then, state two examples of foods. | Animal source, chicken and soya beans |
What type of amino acids do HBV contain | Have all essential amino acids that human need |
What does LBV stand for | Low biological value |
What food source can you only find LBV. Then, list two examples of the foods | Plant-based foods (cereal, nuts) |

What are the two diseases caused by deficiency of protein | Kwashiorkor and oedema |
What does oedema mean | Swelling caused by build up of fluid |
List 4 reasons why we need fat? | 1. Provide energy 2. forming cholesterol 3. providing insulation (heat) 4. source of vitamin (ADEK) |
What is the definition of cholesterol? | A vital component of cell membrane |
What are fat made up of? | Triglycerides (esters formed form fatty acids and glycerol) |
What are fatty acids? | Chains of carbon atom bonded to hydrogen atoms |
What is the chemical bond for saturated fat? | Single C-C bond |
What is the chemical bond for unsaturated fat? | One or more C=C double bond |
Saturated fat are from what food source and what state is it at room temperature? | Animal source, solid |
Unsaturated fat are from what food source and what state is it at room temperature | Vegetable source with high-fat content, liquid |
What are the two types of unsaturated fat | Monosaturated and polysaturated fats |
What is the difference between monosaturated fat and polysaturated fat? | Monosaturated have one C=C double bond, polysaturated has two or more C=C double bond |
What are examples of monosaturated fat | Avocado, hazelnuts |
What are examples of polysaturated fat | Walnuts, seeds |

What are the three diseases caused by excess of fat | Obesity, type 2 diabetes, coronary heart diseases |
What happens of fat to cause cholesterol level to rise | Fat restricts the flow of blood around body by clogging blood vessels |
What are the three consequences of deficiency of fat | Less insulation (heat), loss weight, dont get enough fat soluble vitamin (ADEK) which causes bones cruises easier |
What are two major types of carbohydrate | Sugar and starch |
Is sugar simple or complex? What is sugar also called as? | Simple, it is also called as 'empty calories' as it supplies energy without providing any nutritional benefits |
Is starch simple or complex carbs? What are three examples of starchy food? Those foods contain what three types of micronutrients? | Complex. paste, rice, beans. Vitamin B, Iron, Calcium |
Bodies converts starch and sugar into what? | Glucose, it is then absorbed in blood and converted into energy |
Where are carbohydrate stored in the body | Liver and muscles |
What are the two examples of complex carbohydrate | Starch polysaccharides |
Why are energy released slower in complex carbohydrate | Because it cannot be digested as quickly as simple carbs therefore raises blood sugar more slowly |
What are the two types of sugar molecule in simple carbs | Monosaccharides and disaccharides |
What are monosaccharides and list two examples of it | Basic sugar molecules. Glucose and fructose |
What are disaccharides and list one example of it | Two monosaccharides. surcose |
Why does simple carbohydrate have short energy burst? | It digests quickly, which raises blood sugar level faster |
What does the GI stand for | Glycaemic Index |
What is a Glycaemic Index | Ranks carbs on how quickly they change blood sugar level |
What are the two things that high GI foods do. What are the 3 examples of high GI foods? | High GI foods are digest by body rapidly, causing quicker raise of blood sugar level. White bread, White rice, Rice cakes |
What are the two things that low GI foods do. What are the 3 examples of low GI foods? | Low GI foods are digest by the body slowly, causing slow changes on blood sugar level. Lentils, sweet potato, whole wheat bread |
What kind of people uses Glycaemic Index | Diabetics people |
How many percentage from the daily energy intake is carbs? | 50%, 5% from added sugar |
What are the 4 consequences of excess of carbs | Tooth decay, type 2 diabetes, high blood sugar level, build up fat |
What are the 4 consequences of deficiency of carbs | Low blood sugar level, weight loss, fat deficiency, protein deficiency |
What are starch? | It is a form of carbohydrates, referred to non-starch polysaccharide or roughage |
What are the 5 sources of fiber | Fruits, vegetables, beans and pulses, nuts and seeds, wholegrain breakfast cereals |
What are the 5 deficiency of fiber? | Weight gain, high blood pressure, heart disease, bowel cancer, constipation |
