“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
provide 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,
