    1. What are some of the major functions of macronutrients? What are some prime sources of macronutrients in your own diet? In what ways are carbohydrates, lipids, proteins, and fibers alike in relation to health, morbidity, and mortality? In what ways are they different? If the established standard amount of a nutrient is good for you, is consuming more of the nutrient better for you? Explain your answer.

    2. What are the strengths and weaknesses of your current diet? What factors should you consider before taking dietary supplements? In what ways are supplements beneficial or harmful? What should the role of the government be in influencing people's dietary decisions? Should there be set nutritional standards for food production and food consumption? Explain your answer.

    3. Are carbohydrates good for you? Explain why or why not. Imagine that you have gained 20 pounds over the past 5 years. You decide to use a low-carbohydrate diet to return to a more healthy weight. Although you are happy with your initial weight loss, you begin to experience headaches and bad breath. What is causing these symptoms? Explain your answer.

    Macronutrients are dietary nutrients needed by the body to thrive.

    Carbohydrates supply energy to the body. Good sources of carbohydrates include fruits, vegetables, whole grain cereals, bread, and pasta.

    Protein builds and repairs muscles. Lean meat, fish, poultry, low fat dairy products, nuts and legumes are good sources.

    Lipids (fats) help to store energy and insulate the body. Most diets have plenty of fat already in them, but one should try to use more "soft" fat such as olive and canola oils, peanut better, nuts, and flaxseed are good sources.

    Carbohydrates, lipids, proteins and fibers are alike in relation to health, morbidity, and mortality in that one must consume the proper amount and best quality for optimal health. Consuming too much or making poor choices can lead to morbidity and mortality. An example is a diet that is balanced in smart, health food choices in the right quantities would promote health compared to a diet with processed, prepared foods high in trans fats, red meat, and refined baked goods would result in lower energy levels, greater calories (and presumably weight gain), and less efficient operation of the body. Each of these parts need to be optimized for health. These items are different in that each component must be looked at individually to determine the correct portion size for each person based on desired weight, gender, age, and activity level.

    Consuming more of a nutrient may be better for you, depending on your goal and lifestyle. For instance, competitive endurance athletes will want to ingest more carbohydrates to have an adequate supply of energy for their training needs. Also, some athletes need to ...
