1. Relate the essential components of a well-balanced diet to their impact on health outcomes. 2. Describe the common etiologic factors, clinical manifestations, and management of malnutrition. 3. Describe the components of a nutritional assessment. 4. Explain the indications, complications, and nursing management principles related to the use of enteral nutrition. 5. Explain the indications, complications, and nursing management related to the use of parenteral nutrition. 6. Compare the etiologic factors, clinical manifestations, and nursing management of eating disorders. This chapter focuses on problems related to nutrition. A review of normal nutrition provides a basis for evaluating nutritional status. Malnutrition and types of supplemental nutrition, including enteral and parenteral nutrition, are discussed. Obesity is discussed in Chapter 41. Nutrition is the sum of processes by which one takes in and utilizes nutrients.1 Nutritional status can be viewed as a continuum from undernutrition to normal nutrition to overnutrition. An alteration in the process of nutrient intake or utilization can potentially cause nutritional problems. Nutritional problems occur in all age-groups, cultures, ethnic groups, and socioeconomic classes and across all educational levels. The nutritional status of a person or a family is influenced by many factors. Attitudes toward the importance of food and eating habits are established early. Cultural or religious preferences and requirements are frequently reflected in dietary intake. The financial status of a family or an individual may influence the type and amount of nutritionally sound food that can be purchased.2 eTABLE 40-1 The Food Patterns suggest amounts of food to consume from the basic food groups, subgroups, and oils to meet recommended nutrient intakes at 12 different calorie levels. Nutrient and energy contributions from each group are calculated according to the nutrient-dense forms of foods in each group (e.g., lean meats and fat-free milk). The table also shows the number of calories from solid fats and added sugars (SoFAS) that can be accommodated within each calorie level, in addition to the suggested amounts of nutrient-dense forms of foods in each group. 1Calorie Levels are set across a wide range to accommodate the needs of different individuals. The attached table “Estimated Daily Calorie Needs” can be used to help assign individuals to the food pattern at a particular calorie level. 2Fruit Group includes all fresh, frozen, canned, and dried fruits and fruit juices. In general, 1 cup of fruit or 100% fruit juice, or cup of dried fruit can be considered as 1 cup from the fruit group. 3Vegetable Group includes all fresh, frozen, canned, and dried vegetables and vegetable juices. In general, 1 cup of raw or cooked vegetables or vegetable juice, or 2 cups of raw leafy greens can be considered as 1 cup from the vegetable group. 4Grains Group includes all foods made from wheat, rice, oats, cornmeal, barley, such as bread, pasta, oatmeal, breakfast cereals, tortillas, and grits. In general, 1 slice of bread, 1 cup of ready-to-eat cereal, or cup of cooked rice, pasta, or cooked cereal can be considered as 1-ounce–equivalent from the grains group. At least half of all grains consumed should be whole grains. 5Protein Foods Group includes meat, poultry, seafood, eggs, processed soy products, and nuts and seeds. In general, 1 ounce of lean meat, poultry, or seafood, 1 egg, 1 Tbsp peanut butter, or ounce of nuts or seeds can be considered as 1-ounce–equivalent from the protein foods group. Also, cup of beans or peas may be counted as 1-ounce–equivalent in this group. 6Dairy Group includes all milks, including lactose-free products and fortified soymilk (soy beverage), and foods made from milk that retain their calcium content, such as yogurt and cheese. Foods made from milk that have little to no calcium, such as cream cheese, cream, and butter, are not part of the group. Most dairy group choices should be fat-free or low-fat. In general, 1 cup of milk or yogurt, ounces of natural cheese, or 2 ounces of processed cheese can be considered as 1 cup from the dairy group. 7Oils include fats from many different plants and from fish that are liquid at room temperature, such as canola, corn, olive, soybean, and sunflower oil. Some foods are naturally high in oils, like nuts, olives, some fish, and avocados. Foods that are mainly oil include mayonnaise, certain salad dressings, and soft margarine. 8SoFAS are solid fats and added sugars. The limits for calories from SoFAS are the remaining amount of calories in each food pattern after selecting the specified amounts in each food group in nutrient-dense forms (forms that are fat-free or low-fat and with no added sugars).

Drug Category/Drug
Food/Nutrient
Drug-Food Effects or Cautions
Anticoagulants
Dietary vitamin K (e.g., green leafy vegetables, green tea, dairy products/meats)
Decrease or loss of anticoagulant effect
Antiseizure agents
Folate (folic acid)
Long-term drug use may increase folic acid requirement
Antidepressants
Food
Riboflavin
Food slows drug absorption
Riboflavin requirements may increase with amitriptyline (Elavil) or imipramine (Tofranil)
Antidiabetic agents
High-fat diet
Drug should not be taken with high-fat diet
Barbiturates
Folate (folic acid)
Drugs may increase folic acid requirements; long-term therapy may require vitamin D supplements for osteomalacia
β-Adrenergic blockers
Food
Bioavailability of these drugs may be enhanced when taken with food
Bronchodilators
High-carbohydrate, low-protein diets
Caffeine-containing foods and fluids
↓ Drug elimination
Caffeine may increase CNS-stimulant effects of xanthine-derivative bronchodilators
Corticosteroids (prolonged therapy)
Salt seasonings
May require decreased sodium and/or potassium supplementation intake
Phenothiazines
Riboflavin
Food and fluids containing tyramine (e.g., aged cheese, smoked or pickled meats or poultry, fermented meat, beer, wine, liqueurs)
Drugs may increase riboflavin requirements
When used concurrently, may cause sudden and severe hypertensive reactions; dietary restrictions need to continue for at least 2 wk after MAO inhibitors discontinued
Zinc supplements
Foods
Many foods (e.g., fiber, milk casein) impair zinc absorption
Others
etidronate (Didronel)
Foods, fluids, or drugs high in calcium
May prevent drug absorption
isoniazid (INH)
Cheese (e.g., Swiss) or fish (e.g., tuna, skipjack)
Concurrent ingestion may lead to redness or itching, HR changes, sweating, chills or clammy feeling, headache or light-headedness; thought to be related to altered metabolism of tyramine in foods
selegiline (Eldepryl)
Food and fluids containing tyramine (e.g., see above)
Same as above
ticlopidine (Ticlid)
Food
Drug absorption increased when taken after a meal
zafirlukast (Accolate)
High-fat and high-protein meal
When taken concurrently, drug bioavailability reduced by about 40%
cholestyramine (Questran)
Fat-soluble vitamins
Drug may interfere with their absorption

↓ Growth rate, ↓ body stature with chronic PCM, ↓ muscle mass
Prominence of bony structures such as face, clavicle, scapula, ribs, iliac crests, and spinal vertebrae caused by subcutaneous tissue loss; weak and spindly arms and legs, flat buttocks, weak and flabby muscles; ↓ physical activity and ability to work; severe weight loss
Neurologic
Loss of ambition, feeling of being tired
Depression, confusion, ↓ reflexes in legs and ankles, ↓ position sense, ↓ vibratory sense, paresthesias of hands and feet, syncope, motor weakness
Renal
