shows some of the information on the packets of two breakfast cereals. Cereal C Cereal D Nutrition Information Typical value per 100 g ENERGY 1623 kJ PROTEIN 13 g CARBOHYDRATE of which sugars starch 78 g 24 g 54 g FAT of which saturates 1.5 g 0.5 g FIBRE 2.5 g SODIUM SALT 0.4 g 1 g VITAMINS: VITAMIN D VITAMIN C THIAMIN (B1) RIBOFLAVIN (B2) NIACIN VITAMIN B6 FOLIC ACID VITAMIN B12 (% GDA) 7.4 µg (147) 88 mg (147) 2.1 mg (147) 2.4 mg (147) 26.5 mg (147) 2.9 mg (147) 294 µg (147) 1.47 µg (147) MINERALS: IRON 16.2 mg (73) Nutrition Information Typical value per 100 g ENERGY 1600 kJ PROTEIN 10 g CARBOHYDRATE of which sugars starch 68 g 20 g 48 g FAT of which saturates 5 g 0.9 g FIBRE 9 g SODIUM SALT 0.01 g 0.03 g VITAMINS: THIAMIN (B1) RIBOFLAVIN (B2) NIACIN VITAMIN B6 FOLIC ACID VITAMIN B12 (% GDA) 1 mg (73) 2.3 mg (145) 13.1 mg (73) 2.9 mg (145) 290 µg (145) 0.73 µg (73) MINERALS: IRON 10.2 mg (73) The Guideline Daily Amount (GDA) of energy for an average adult is 8 400 kJ. Calculate the percentage of this GDA a person would obtain by eating one 25 g serving of Cereal D. Show your working in the space provided. Answer % State how the daily energy requirement of a hard-working farmer would differ from the GDA described above. Cereal D is considered to be better for people suffering from constipation than Cereal C. Suggest a reason for this. Rickets is a condition that affects some children. Describe the symptoms of rickets. State which cereal, C or D, should be eaten by children to prevent rickets and explain your answer. cereal explanation
