Macronutrients are the nutrients your body needs in large amounts. There are three main macronutrients: protein, carbohydrates, and fat.
Protein is made of amino acids. It helps oxygen circulate through the blood, strengthens your immune system, participates in your "muscle contractions and movement", and helps support your hair. The macronutrient protein is broken down slowly, so it will provide you with long-term energy. About thirteen percent of your diet should be protein, which can be found in meat, dairy, fish, and eggs.
Carbohydrates are split into three groups: monosaccharides (which are made of glucose and fructose), disaccharides (made of two combined monosaccharides), and polysaccharides (starches and fibers; also called com
plex carbohydrates). Carbohydrates supply less energy than proteins or fats, but they are important for central nervous system functions. They should make up around fifty-seven percent of your diet and can be found in cereals, grains, bread, oatmeal, rice, and pasta.
Fats are made of lipids and are classified into five groups. Saturated fat (and also trans fat) is a major cause of coronary heart disease. Monounsaturated fats offer protection, but polyunsaturated fats do not cause or protect you from it. Essential fatty acids are required for healthy cardiovascular, immune, reproductive, and nervous systems. Cholesterol is needed for bodily functions (low-density lipoprotein carries fat into the arterie
s while high-density lipoprotein carries fat away from them). About thirty percent of your diet should be fats, which can be found in red meat, shellfish, corn & olive oil, and butter.
Micronutrients
Micronutrients are the nutrients that your body needs in smaller amounts. They let your body make enzymes, hormones, and other substances needed for proper growth. You should have 1300mg of calcium, 18mg of iron, 60mg of vitamin C, 1000mg of phosphorus, 150 mcg of iodine, 400mg of magnesium, and 15mg of zinc daily.

Good job! I feel like this was very well written. It contains a lot of good information on Protein, Carbohydrates, and Fats without each one being to long. This group also went an extra step and included information on Micronutrients as well.
