amounts of various nutrients, as well as the %DV, which is the percentage of recommended daily values those amounts represent.

LO 3 | How Can I eat More Healthfully? With a little menu planning, veg-

etarianism can be a healthful lifestyle choice, providing plenty of nutrients, plus fiber and phytochemicals, typi- cally with less saturated fat and fewer calories.

Although some people may benefit from taking vitamin and mineral sup- plements, a healthy diet is the best way to give your body the nutrients it needs.

College students face unique chal- lenges in eating healthfully. Learning to make better choices, to eat health- fully on a budget, and to eat nutri- tionally in the dorm are all possible when you use the information in this chapter.

LO 4 | Food Safety: A growing Concern Organic foods are grown and pro-

duced without the use of toxic and persistent synthetic pesticides, fertiliz- ers, antibiotics, hormones, or genetic modification. The USDA offers certifi- cation of organic farms and regulates claims regarding organic ingredients used on food labels.

Foodborne illnesses can be traced to contamination of food at any point from fields to the consumer’s kitchen. To keep food safe at home, follow four steps: Clean, separate, cook, and chill.

Food allergies, celiac disease, food intolerances, GM foods, and other food safety and health concerns are becoming increasingly important to health-wise consumers. Recognizing potential risks and taking steps to prevent problems are part of a sound nutritional plan.

LO 1 | essential Nutrients for Health Nutrition is the science of the rela-

tionship between physiological function and the essential elements of the foods we eat. The Dietary Reference Intakes (DRIs) are recom- mended nutrient intakes for healthy people.

The essential nutrients include water, proteins, carbohydrates, fats, vita- mins, and minerals. Water makes up 50 to 60 percent of our body weight and is necessary for nearly all life processes. Proteins are major compo- nents of our cells and tissues and are key elements of antibodies, enzymes, and hormones. Carbohydrates are our primary sources of energy. Fats provide energy while we are at rest and for long-term activity. They also play important roles in maintaining body temperature, cushioning and protecting organs, and promoting healthy cell function. Vitamins are organic compounds, and minerals are inorganic elements. We need these micronutrients in small amounts to maintain healthy body structure and function.

LO 2 | Nutritional guidelines A healthful diet is adequate, moder-

ate, balanced, varied, and nutrient dense. The Dietary Guidelines for Americans and the MyPlate plan provide guidelines for healthy eating. These recommendations, developed by the USDA, place emphasis on bal- ancing calories and understanding which foods to increase and which to decrease.

The Nutrition Facts label on food labels identifies the serving size, number of calories per serving, and

cHapter 9 | Nutrition: Eating for a Healthier You | 263

two groups—vitamins and minerals—are needed in smaller amounts, so they are called micronutrients.

Before the body can use food, the diges- tive system must break down larger food

particles into smaller, more usable forms. The digestive process is the sequence of functions by which the body breaks down foods into molecules small enough to be absorbed, and excretes the wastes.

recommended intakes for nutrients

In the next sections, we discuss each nutrient group and identify how much of each you need. These

recommended amounts are known as the Dietary Refer- ence Intakes (DRIs) and are published by the Food and Nutrition Board of the Institute of Medicine. The DRIs estab- lish the amount of each nutrient needed to prevent deficien- cies or reduce the risk of chronic disease, as well as identify maximum safe intake levels for healthy people. The DRIs are umbrella guidelines and include the following categories:

Recommended Dietary Allowances (RDAs) are daily nutrient intake levels meeting the nutritional needs of 97 to 98 percent of healthy individuals.

Adequate Intakes (AIs) are daily intake levels assumed to be adequate for most healthy people. AIs are used when there isn’t enough research to support estab- lishing an RDA.

Tolerable Upper Intake Levels (ULs) are the highest amounts of a nutrient that an individual can consume daily without risking adverse health effects.

Acceptable Macronutri- ent Distribution Ranges (AMDRs) are ranges of pro- tein, carbohydrate, and fat intake that provide adequate nutrition, and they are asso- ciated with a reduced risk for chronic disease.

Whereas the RDAs, AIs, and ULs are expressed as amounts— usually milligrams (mg) or micrograms (μg)—AMDRs are expressed as percentages. The AMDR for protein, for example, is 10 to 35 percent, meaning that no less than 10 percent and no more than 35 percent of the calories you consume should come from proteins. But that raises a new question: What are calories?

advice about food comes at us from all direc-tions: from the Internet, popular mag-azines, television, friends, and neighbors. Even when backed by research, this advice can be contradic- tory. Some studies indicate that a bal- anced high-fat diet can be healthful, whereas other studies support con- suming a low-fat diet. Choosing what to eat and how much to eat from this media-driven array of food advice can be mind-boggling. For some, this can cause unnecessary anxiety about eating and lead to a lifetime of cycling on and off diets.1 Why does something that can be a source of pleasure end up being a prob- lem for so many of us? What influences our eat- ing habits, and how can we learn to eat more healthfully?

The answers to these questions aren’t as simple as they may seem. When was the last time you ate because you felt truly hungry? True hunger occurs when our brains initiate a physiological response that prompts us to seek food for the energy and nutrients that our bodies require to maintain proper functioning. Often, people in the United States don’t eat in response to hunger—instead, we eat because of appetite, a learned psychological desire to consume food. Hunger and appetite are not the only forces influencing our desire to eat. Cultural factors, food advertising, perceived nutritional value, social interaction, emotions, and financial means are other factors.

Nutrition is the science that investigates the relationship between physiological function and the essential elements of the foods we eat. With an understanding of nutrition, you will be able to make more informed choices about your diet. Your health depends largely on what you eat, how much you eat, and the amount of exercise that you get throughout your life. The next few chapters focus on fundamental principles of nutrition, weight management, and exercise.

LO 1 | essentiaL NutrieNts for HealtH List the six classes of nutrients, and explain the primary functions of each and their roles in maintaining long-term health.

Food provides the chemicals we need for activity and body maintenance. Our bodies cannot synthesize certain essential nutrients (or cannot synthesize them in adequate amounts); we

must obtain them from the foods we eat. Of the six groups of essential nutri- ents, the four we need in the largest amounts— water, proteins, carbohy- drates, and fats—are called macronutrients. The other

WHY SHouLD I CArE?

The nutritional choices you make during college can

have both immediate and lasting effects on your health. Thousands

of studies associate what we eat with chronic diseases such as diabetes,

heart disease, hypertension, stroke, osteoporosis, and

many types of cancer.

will provide adequate amounts of protein. Pregnant women, older adults, sick people, and families with young children who are vegans need to take special care to ensure that their diets are ade- quate. In all cases, seek advice from a health care professional if you have questions.

supplements: research on the Daily Dose Dietary supplements are products containing one or more die- tary ingredients taken by mouth and intended to supplement existing diets. Ingredients range from vitamins, minerals, and herbs to enzymes, amino acids, fatty acids, and organ tissues. They can come in tablet, capsule, liquid, powder, and other forms. Because consumers see dietary supplements as an easy fix to improve their less than healthy diets, sales have skyrocketed.

It is important to note that dietary supplements are not reg- ulated like foods or drugs. The FDA does not evaluate the safety and efficacy of supplements prior to their marketing, and it can take action to remove a supplement from the market only after the product has been proved harmful. Currently, the United States has no formal guidelines for supplement market- ing and safety, and supplement manufacturers are responsible for self-monitoring their activities.

Do you really need to take dietary supplements? The Office of Dietary Supplements, part of the National Institutes of Health, states that some supplements may help ensure that you get adequate amounts of essential nutrients if you don’t consume a variety of foods, as recommended in the Dietary Guidelines for Americans. However, dietary supplements are not intended to prevent or treat disease, and recently the U.S. Pre-

The wisdom of taking other types of supplements, as opposed to consuming nutrients in whole foods, is also unproven. For example, the benefit of fish consumption in reducing the risk for cardiovascular disease is well-established, but studies have shown conflicting results about fish-oil supplements.46

Taking high-dose supplements of the fat-soluble vitamins A, D, and E can be harmful or even fatal. Too much vitamin A, for example, can damage the liver, and excessive vitamin E

Adopting a vegetarian diet can be a very healthy way to eat. Take care to prepare your food healthfully by avoiding added sugars and excessive sodium. Make sure you get comple- mentary essential amino acids throughout the day. Meals like this tofu and vegetable stir-fry can be further enhanced by adding a whole grain, such as brown rice.
