Describe a line graph

Hello,

Could you please check out my very first post and correct it? Thanks a lot.

The line graph indicates changes in the amounts of fish and three types of meat consumed in a European country from 1979 to 2004.

Overall, there was an upward trend in the consumption of chicken while a downward trend can be seen in the amounts of the other foods consumed. It is clear that the consumption of fish was the lowest during the time surveyed. The amount of chicken consumed went up dramatically from just under 150 grams per person per week to about 250 grams per person per week in a 26-year period, starting from 1979. The consumption of beef in the same period, however, experienced a sharp decrease from about 220 grams per person per week to about 120 grams per person per week. Likewise, a considerable fall of 70 grams per person per week in the amount of lamb consumed was recorded from 1979 to 2004. In addition, the consumption of fish declined slightly by about 10 grams per person per week from just over 60 grams per person per week in 1979 to 50 grams per person per week in 2004
