It is true that the consumption of healthy food has played a vital role.
3 problems with this opening sentence. First, it is stating a personal opinion of the writer instead of the topic representation. Second, the sentence is incomplete in thought / idea presentation. The subject of the sentence is healthy food. What is the predicate for the vital role? See the problem? Third, the writer seems to be required by the writing guide to provide his own opinion in this section. Where is it? This is a compare and contrast 3 points of view essay format.
As for the discussion itself, the writer will definitely receive a failing LR score because he misspells English words and does not know the meaning of the word well enough to use it properly in the sentence / paragraph. He does not effectively explain his reasons and also does not seem to understand the reasons well enough to use it.
Missing from the presentation are the GRA pronoun requirements to show that the 3 points of view are being discussed. This also led to the incorrect discussion format since the 2 public opinions are not completely discussed. It jumped from a public discussion to a personal one in the next paragraph. Therefore, the essay does not meet the discussion format requirements. It is not going to receive a passing score based on these mistakes alone.
