Band 7+: The table below gives information on the proportion of carbohydrates, protein and fat in three different diets. Write a report for a university lecturer describing the information shown below. Make comparisons where relevant.

The pie charts illustrate the percentages of consumed carbohydrates, protein, and fat in each type of diet followed by people, namely average, healthy, and sport-oriented.

In general, all of these diets have in common not only the largest part of all consumed food, which is carbohydrates, but also the second biggest part, which is protein; however, the level of fat eaten is the same for average and healthy diets, and slightly different for the sport diet.

The amount of protein for the average person is the same as the amount of carbohydrates, and one-fifth of the total consists of fat, which is the same for healthy and average eating; however, for a healthy diet, there is a gradually lesser rate of protein, and half of the diet is carbohydrates, which is 10% bigger than the normal diet. Whereas, for sport eating, the proportions are slightly different than in those diets: the amount of carbohydrates, compared with the average, is 20% bigger and 10% bigger than in the health-oriented diet; protein is a quarter of all sport rations, which is less than 40% in the average diet and 30% for the healthy diet; fat is minimally different between the average and sporty diets—5% less for the latter.
