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.
