From basic nutrition principles to the latest nutrition therapies for common diseases, Williams’ Essentials of Nutrition & Diet Therapy, 10th Edition, Revised Reprint offers a solid foundation in the fundamental knowledge and skills you need to provide effective patient care. Authors Eleanor Schlenker and Sara Long address nutrition across the life span and within the community, with an emphasis on health promotion and the effects of culture and religion on nutrition. The revised edition has been updated with current government dietary guidelines, including the new MyPlate recommendations. Other key topics include childhood obesity, metabolic syndrome, diabetes, and food safety. Plus, evidence-based information and real-world case scenarios help you learn how to apply essential nutrition concepts and therapies in clinical practice.

New challenges for nutrition professionals
The Obesity Epidemic
FIGURE 1-1 The obesity epidemic among U.S. adults. Notice the rise in the number of states in which at least one fourth (25%-29%) of the residents are obese. By 2008, only one state had an obesity prevalence below 20%, and 32 states had a prevalence of at least 25%. (Obesity is defined as a body mass index of 30 or greater, which is the equivalent of 30 lb overweight for a person 64 inches tall.)
BOX 1-1 Factors Contributing To Increased Food Intake
Shifts in Population
Number of Older Adults
FIGURE 1-2 Change in portion size of common foods. Over the last 20 years, portion sizes have almost tripled. A hamburger and roll that supplied 260 kcal may now contain 850 kcal. Visit the website of the National Heart, Lung and Blood Institute, National Institutes of Health (http://hp2010.nhlbihin.net/portion/keep.htm) to view photographs of many food items that have changed in size and kcalorie content. Take the quiz to learn how many minutes you would need to exercise to burn the extra kcalories.
Ethnic and Racial Diversity
FIGURE 1-3 Projected increases in the number of persons age 65 and older. Between 1900 and 2000, the older age group grew from 3 million to 37 million and currently makes up 12% of the general population. By 2030, this group will number 70.5 million and represent almost 20% of the general population. By 2050, 21 million people will be at least age 85.

Types of Muscles
FIGURE 2-2 Muscle layers of the intestinal wall. Notice the five layers of muscle that produce the movements necessary for digestion and keeping the food mass going forward.
FIGURE 2-3 Types of movement produced by muscles of the intestine: peristaltic waves from contraction of deep circular muscle, pendular movements from small local muscles, and segmentation rings formed by alternate contraction and relaxation of circular muscle.
FIGURE 2-4 Innervation of the intestine by the intramural nerve plexus. A network of nerves controls and coordinates the movements of the intestinal muscles.

FIGURE 3-1 Photosynthesis. In the presence of sunlight and the green leaf pigment chlorophyll, green plants use water and carbon dioxide (CO2) to produce glucose and starch by capturing the sun’s energy and transforming it into chemical energy in the food products stored in their roots, stems, and leaves; through this process oxygen is returned to the atmosphere.
