at least I see a grammar error:
There were 7 vital dishes which were divided into two groups in The America's meals were high and low calorie food.
should be:
There were 7 vital dishes which were divided into two groups in The America's meals that were high and low calorie food.
or:
7 vital dishes which were divided into two groups in The America's meals were high and low calorie food.
