Functional foods contain potentially beneficial compounds derived from plants phytochemicals or animals zoochemicals. Consumed as part of a healthy diet, these foods may help prevent adverse health conditions; but problems can arise if too much of a particular compound is consumed.
This is a particular risk when consuming prepackaged functional foods. After reading this chapter, students should be able to: 1. Describe the three key principles of a healthy diet and the tools you can use to help guide you. Describe the principles in the Dietary Guidelines for Americans. Explain the concept of MyPlate and name the five food groups and the typical foods represented in each group.
Identify the required components of a food label and how to use it. Explain the role of functional foods in the diet. Chapter Outline I. Healthy eating involves the principles of balance, variety, and moderation. A balanced diet includes healthy proportions of all nutrients. A varied diet includes many different foods. A moderate diet provides adequate amounts of nutrients and energy. Undernutrition is a state of not meeting your nutrient needs. Malnourishment may result from not meeting nutrient needs on a long-term basis.
Overnutrition is a state of having too much of a nutrient or too many calories. Some nutrients can be toxic in high amounts. Too many calories can lead to obesity. A person who is overnourished can also be malnourished. Tools such as the Dietary Reference Intakes, the Dietary Guidelines for Americans, MyPlate, and the Nutrition Facts panel on food labels may be used to help you avoid states of undernutrition or overnutrition.
Figure 2. What Are the Dietary Reference Intakes? National Academy of Sciences. DRIs are specific amounts of each nutrient needed to maintain good health, prevent chronic disease, and avoid unhealthy excesses. DRIs tell you how much of each nutrient you need. Nutrition research in the s suggested that higher amounts of certain nutrients might impact disease prevention; subsequent research has also looked at dietary supplements and the potential problems of excessive consumption.
As research evolves, changes are made in the DRIs. DRIs encompass several reference values. The EAR is the average amount of a nutrient known to meet the needs of 50 percent of the individuals in a similar age and gender. This is considered a good starting point for determining the daily amount needed for good health.
The RDA represents the average amount of a nutrient that meets the needs of nearly all 97—98 percent of the individuals in a similar age and gender group. Adequate Intake AI a.
An AI is the approximate amount of a nutrient estimated for individuals to consume in a similar age and gender group to maintain good health. The UL is the highest amount of a nutrient that may be consumed daily without harm.
The higher the consumption above the UL, the greater the risk of toxicity. The AMDR are set for the energy-containing nutrients carbohydrates, fat, and protein. The AMDR for carbohydrates is 45 to 65 percent of daily calories. Fats should be 20 to 35 percent of daily calories. Proteins should be consumed at 10 to 35 percent of daily calories.
The EER is the amount of energy, or calories, you need daily. It is calculated based on your age, gender, height, weight, and activity level, and indicates the amount of energy you need daily to maintain energy balance. Ad veri latine efficiantur quo, ea vix nisl euismod explicari.

The summaries include important art and photos from the chapter and serve as concise study and review tools, with accompanying activities in Mastering Nutrition. In addition, Check Your Understanding questions encourage student review and are tied to learning outcomes. Help students make healthy eating choices and relate nutrition to their own lives Updated - Practical Tips Videos show Joan Salge Blake as she walks students through making better eating choices in familiar environments, based on a choice related to the chapter topic.
Examples include a pizza parlor, deli, coffee shop, breakfast choices on-the-go, fitness smoothies, and much more. These dynamic videos are provided in full-screen format in the Instructor Resource Materials in Mastering Nutrition for easy instructor access in class, referenced in the printed text, and are also embedded within the eText.
Health Connection: A Case Study :The connections between nutrition and disease are explored in new case studies written for every chapter. The case study introduces students to a person experiencing a health problem, explores the interplay between nutrition and disease, and concludes with follow-up critical-thinking questions. Dynamic Study Modules help students study effectively-and at their own pace.
By keeping them motivated and engaged. The assignable modules rely on the latest research in cognitive science, using methods-such as adaptivity, gamification, and intermittent rewards-to stimulate learning and improve retention. Each module poses a series of questions about a course topic.
These question sets adapt to each student's performance and offer personalized, targeted feedback to help them master key concepts. With Learning Catalytics , you'll hear from every student when it matters most.
You pose a variety of questions that help students recall ideas, apply concepts, and develop critical-thinking skills. Your students respond using their own smartphones, tablets, or laptops. You can monitor responses with real-time analytics and find out what your students do - and don't - understand. Then, you can adjust your teaching accordingly and even facilitate peer-to-peer learning, helping students stay motivated and engaged.
Updated for this edition: newly added clicker questions from the Digital Instructional Resources. It allows students to easily highlight, take notes, and review key vocabulary all in one place-even when offline.
