A balanced diet contains seven different groups of substances. Three of these groups of substances are fats, fibre and vitamins. State the names of three other groups of substances in a balanced diet. The boxes on the left contain the names of conditions that can develop if the diet is not balanced for a long period of time. The boxes on the right contain descriptions of how these conditions may be caused. Draw one straight line from each box on the left to a box on the right to link the condition to its cause. name of condition description of cause constipation obesity scurvy starvation diet contains very little fibre diet very high in protein eating more food than is necessary lack of enough food lack of fruits such as oranges

The nutrient content of five different foods was analysed. The mass of each nutrient per 100 g of food was estimated. Table 1.1 shows the results. Table 1.1 mass of nutrient per 100 g of food / g food carbohydrates fats protein fibre A B C D E The recommended daily allowance for these nutrients for an adult is: • fat – a maximum of 70 g per day • protein – 50 g per day. Identify the food in Table 1.1 which contains the most carbohydrate per 100 g. A person eats 200 g of each food. Using the information in Table 1.1, identify the two foods that would provide more than the recommended daily allowance of fat. and Using the information in Table 1.1, calculate the number of grams of food C needed to provide the recommended daily allowance of protein. g State two groups of nutrients missing from Table 1.1 that are needed as part of a balanced diet. Explain why food E is recommended as part of a balanced diet. Most foods contain some carbohydrates. State the names of the chemical elements contained in carbohydrates. Starch is a type of carbohydrate. Circle the names of two other carbohydrates from the list. amino acids amylase cellulose ethanol glycogen oil protein urea
