Carboydrates is the body's main source of energy. There are 2 different types of Carbohydrates, one is Simple Carbs: it uses one or two sugars, usualy processed foods. The second is called Complex Carbs: it uses three or more sugars, and it takes longer to digest.
i chose Carbohydrates because it provides energy to the body so in the middle of the day. I believe carbohydrates is the most imporatant because without energy we would crash, feel empty, and feel tired, because ou energy isnt in our body. The other reason is we need all of the nutrients so we can be healthy. In my opinion, Carbohydrates are not necciseraily the BEST food to eat, BUT we do need more of them in our body.
