ESTEFANIA

Not only do all of us try to eat healthy food every day, but all of us also eat unhealthy food and enjoyed it. Moreover, in 2014 we are trying to eat healthy food every day. In addition, we try to eat homemade healthy food at home. New York City has all kind of food markets so you can buy any food here. This is the one of the reason people like to live in New York City forever.

Very nice work. Estefania.

I think the sentence that begins "Moreover, in 2014" should use the future tense: "Moreover, in 2014 we are going to try eating healthy food every day." Your sentence is correct, but I think because 2014 has just begun it makes sense to use the future tense.

When you use "one of the + Noun" the noun should be plural.

correct: "One of the reasons."

Otherwise, it's fine. It's exemplary.
