Food Macromolecules

â€Å"Macromolecules are a source of fuel. There are four major types of macromolecules-proteins, carbohydrates, nucleic acids, and lipids. This process plays important roles in the life of a cell. (Macromolecules, 2002). The macromolecules that was present in the packaged food product Lipids which are fats. According to (Alters & Alters 2009, p. 49) Fats also provide more energy in our diets that do equivalent amounts of carbohydrates or protein. Protein was also present on the packaged food. Proteins transport and rovide muscle contraction. Alters & Alters 2009, p. 51) Proteins build, maintains, and replaces the tissue in our body. Tissue meaning: muscles, organs, and your immune system. They are also important for the movement of lungs, legs, and protecting you from disease. (Learning about proteins,2008). How much protein do we need each day? Adults should get a minimum of 0. 8 grams of protein for every kilogram of body weight per day. Increasing protein intake helps reduce the risk of heart disease. (The Nutrition Source: Protein, 2011). Carbohydrates are also present in the packaged food. Carbohydrates provide the body with fuel for physical activity and proper organ function. The best sources of carbohydrates -whole grains, vegetables, fruits, and beans- promote good health. (The Nutrition Source: Carbohydrates, 2011) Lipids are also present in the packaged food. Lipids are a group of molecules that consist of fats, phospholipids, and cholesterol. This packaged food is a part of a heart healthy diet because it has carbohydrates, low saturated fats, and proteins. Carbohydrates are important for fuel, breaking these bonds and releasing energy to sustain life (Alters & Alters, 2009, p. 47). Large amounts of saturated fats may lead to clogged arteries and risk of heart disease. (Alters & Alters, 2009, p. 50). The product I have chosen to use is Quaker Oatmeal. I consider carbohydrates to be the most important thing listed on the label. Knowing the amount of carbohydrates is important because carbohydrates turn into sugar, and there is only one gram of sugar in this product. When carbohydrates turn into ugar this increases the risk of diabetes if there is to much carbohydrates in your diet. I have never been a health fanatic, but after doing this essay I need to be a little cautious of what I am eating. I have found that reading labels helps us to eat healthier and to make the right choices our life style. I never really understood how carbohydrates work. Now I know the understanding of good and bad carbohydrates. Heart disease runs in my family. I do have a healthy heart but after doing the research for this essay I hope to continue to stay healthy.
