The given line graph illustrates the changes in the use of different kinds of proteins, namely chicken, beef, lamb and fish for one people in one week in the year 1979-2004.

Overall, there was an increase in white meat consumption and it prevailed over red meat consumption from 1989-2004. Fish consumption was quite stable during 25 years of research.

Chicken and lamb uses had the same starting point of 150 grams per person per week in 1979 and went their separate ways after that. Chicken consumption increased sharply up to 250 grams in 2004, which was the highest amount of chicken consumed over 25-year period. Conversely, there was a plunge in lamb consumption, which varied from 150 grams in 1979 to approximately 60 grams in 2004. On the other hand, people used to eat beef more than other proteins by the year 1989 and there was a sudden drop in beef consumption after that.

Fish was the least used protein out of the four proteins. Fish consumption almost remained stable at the point of 50 grams per person per week, despite a slight decrease in those first days of the survey.
