Carbohydrates are composed of simple carbohydrates (sugar), complex carbohydrates (starch), and fiber. Carbohydrates are the primary source of energy in your body. Carbohydrates also has many other smaller functions. Carbohydrate intake is not a precise number due to different factors like weight and needs, but 60-100 g is about the amount a teen should be getting. Carbohydrates are the ones you should get the most of, but reasonable moderation is still necessary. Carbohydrates are found in bread, fruit, vegetables, candy, and milk to name a few.
Proteins are composed of amino acids (which contain elements like nitrogen, carbon, and oxygen). Amino acids, in simple terms are the building blocks of proteins, the individual units. There are many different types of amino acids. Proteins primarily build and repair body tissue like muscles and bones, form enzymes and hormones, and many other smaller but important things. Protein intake varies for each person based on weight and needs, but the normal teenager will probably need somewhere around 70-100 grams. Proteins are found in eggs, chicken, and fish to name some. For vegetarians, you can find them in nuts, beans, and lentils.
