Document Summary
Chapter 5 - nutrition: eating for a healthier you. Hunger - physiological impulse to seek food, prompted by the lack or shortage of basic foods needed to provide the energy and nutrients that support health. Appetite - desire to eat; normally accompanies hunger but is more psychological than physiological. Nutrients - constituents of food that sustain humans physiologically: proteins, carbs, fats, vitamins, minerals, and water. Nutrition - science that investigates the relationship between physiological function and the essential elements of the foods eaten. What we eat is associated with chronic diseases such as diabetes, heart disease, hypertension, stroke and many types of cancer. Digestive process - sequence of functions by which body breaks down foods and either absorbs or excretes them. Food and beverages provide the chemicals we need for activity and body maintenance. Our bodies cannot synthesize certain essential nutrients - must obtain from diet.
