Chapter 1 Outline “Food Choices and Human Health” I. Chapter 1 – “Food Choices and Human Health” (Pages 2-19) a. A Lifetime of Nourishment i. The best food for you is the kind that supports the growth and maintenance of strong muscles,  sound bones, healthy skin, and sufficient blood to cleanse and nourish all parts of your body. ii. Of the leading causes of death, five are related to nutrition iii. Diseases and conditions of poor health appear all along this continuum from purely genetic to  purely nutritional iv. Other major health determinants include: Tobacco, alcohol, physical activity, sleep, stress, and  home and job conditions b. The Human Body and Its Food i. The energy that fuels the body’s work comes indirectly from the sun and by way of plants ii. The body requires six kinds of nutrients 1. Carbohydrates  – Energy-Yielding Nutrient 2. Fats (lipids)  – Energy-Yielding Nutrient. It is the most energy-rich of the nutrients. 3. Protein  – Energy-Yielding Nutrient and provides materials to form structures and parts  of body tissues. 4. Vitamins  – Acts as a regulator to assist in body processes such as digesting food,  moving muscles, disposing of wastes, growing new tissues, healing wounds, and  obtaining energy from carbohydrates, fats, and protein. 5. Minerals  – Serves the same purpose as vitamins and some also serve as parts of body  structures.  6. Water iii. Food scientists measure food energy in calories iv. Food and nutrient quantities are often measured in grams v. Elemental diet formulas do not support growth and health and often lead to medical  complications. vi. When a person is fed through a vein, the digestive organs, like unused muscles, weaken and  grow smaller. c. The Challenge of Choosing Foods i. A nutritious diet has five characteristics 1. Adequacy  – The foods provide enough of each essential nutrient 2. Balance  – The choices do not overemphasize one nutrient or food type  3.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
