Focusing on upward trends first, in 1970, less than 100 grams of hamburgers, fish and chips where eaten by people. However, both types of food consumption increased gradually over the years until reaching above 100 grams in 1980. At that time, Hamburgers consumption substantially rose, and reached at a low of 300 grams in 1990, whilst fish & chips started being favoured more by people and showed a sharp rise of 500 grams in 1990.
