This Unit is very important for our diet and health. We will study the types of foods and energetic requierements of our bodies. We will make a work about diets and will be part of the final note. Even you will never study biology again, is an important lesson for anyone. We all eat on daily basis so we all must know few concepts about this. Please study the Unit hardly as this is one of the easiest units of this course. Good chance to reach a good mark!
