The given graph shows the consumption of fast food in the UK (per week) from 1970 to 1990.

The mentioned line chart elucidates the expenditure of fast food in United Kingdom weekly in the period of 1970 to 1990.
As it can be seen from the chart, hamburger and fish and chips showed an upward trend while the opposite was true for pizza over the span of 20 years from 1970 to 1990. Interestingly, in this period, fish and chips had the most significant changes.

In 1970, pizza was by far the best fast food consumed by inhabitants in the UK at over 300 grams. Meanwhile, the consumptions of hamburger and fish and chips were about 30 and 80 grams respectively. The period between 1970 and 1980 witnessed a marginal drop in the expenditure of pizza while the others increased gradually.

After 1980, there was a rise at 150 grams in the consumption of fish and chip, but later hit the highest point, reaching 500 grams in 1990, which was a surprise. Similarly, the forenamed of hamburger reached a peak at approximately 290 grams. Nevertheless, the expenditure of pizza experienced a steady fall and hit the lowest point at 200 grams, but later went up moderately at 210 grams.

Hi, I liked your report. Expenditure means spending, so you spend on something, not in or of something, and have expenditures on something Here are some other comments and suggestions:

The mentioned line chart elucidates {this sounds a bit odd to me in this context - maybe "gives" or "presents" or "illustrates"} the expenditure on three different types of fast food in the United Kingdom purchased weekly in the period between 1970 and 1990.

As can be seen ..., hamburger {I would use the plural here} and ...

... the most significant change.

In 1970, pizza was by far the most popular fast ... over 300 grams each week per person. Meanwhile, the consumptions {I would use the singular here, as consumption is non-countable} of hamburger ...

...the expenditure on pizza while ...

... at 150 grams {"rise at 150 grams" is unclear to me - I guess you mean that the consumption accelerated rapidly and doubled from 150 to 300 grams in the five years between 1980 and 1985} in the consumption of fish and chips, ...

... reaching 500 ... was a surprise. {why was this a surprise? There is really not enough information for this to be either surprising or expected} Similarly, the forenamed of hamburger {this sounds odd to me, like you have given this hamburger a name, like "Harry the Hamburger"} reached a peak {"hit the highest point" and "reached a peak" to me describe a line that rises to a peak and then falls afterward. So here, I am not sure it is appropriate or clear, since we have no information about what happened after 1990} at approximately 290 grams. Nevertheless, {this is not the best transition. It means "despite this fact" and so is a cause and effect transition. Really what you want is a contrast transition, like "In contrast"} the amount spent on pizza ...

...later went up moderately to 210 grams by the end of the period shown.
