**Older children and teenagers (ages 9-18 yrs) and adults over the age of 50 need 3 servings daily. During pregnancy and lactation, the recommended number of dairy group servings is the same as for nonpregnant women.

How Many Servings Do You Need?

The Food Guide Pyramid shows a range of daily servings for each food group. The number of servings that is right for you depends on how many calories you need. Calories are a way to measure food energy. The energy your body needs depends on your age, sex, and size. It also depends on how active you are. In general, daily intake should be:

■ 1,600 calories for most women and older adults

■ 2,200 calories for children, teen girls, active women, and most men

■ 2,800 calories for teen boys and active men.

Those with lower calorie needs should select the lower number of servings from each food group. Their diet should include 2 servings of protein for a total of 5 ounces. Those with average calorie needs should select the middle number of servings from each food group. They should include 2 servings of protein for a total of

6 ounces. Those with higher calorie needs should select the higher number of servings from each food group. Their diet should include 3 servings of protein for a total of 7 ounces. Also, pregnant or breast-feeding women, teens, and young adults up to age 24 should consume 3 servings of dairy foods daily.

The amount of food that counts as one serving is listed below. If you eat a larger portion, it is more than one serving. For example a slice of bread is one serving. A hamburger bun is two servings.

For mixed foods, estimate the food group servings of the main ingredients. For example, a large piece of sausage pizza would count in the bread group (crust), the milk group (cheese), the meat group (sausage), and the vegetable group (tomato sauce). Likewise, a helping of beef stew would count in the meat group and the vegetable group.

TABLE 3-6 ■ Eating Disorders and Excessively Low BMI

In the United States an estimated 5 to 10 million women and one million men suffer from eating disorders. These severe disturbances of eating behavior are often difficult to detect, especially in teens wearing baggy clothes, or in individuals who binge then induce vomiting or evacuation. Be familiar with the two principal eating disorders, anorexia nervosa and bulimia nervosa. Both conditions are characterized by distorted perceptions of body image and weight. Early detection is important, since prognosis improves when treatment occurs in the early stages of these disorders.

Clinical Features

Anorexia Nervosa

■ Refusal to maintain minimally normal body weight (or BMI above 17.5 kg/m2)

■ Afraid of appearing fat

■ Frequently starving but in denial; lacking insight

■ Often brought in by family members

■ May present as failure to make expected weight gains in childhood or adolescence, amenorrhea in women, loss of libido or potency in men

■ Associated with depressive symptoms such as depressed mood, irritability, social withdrawal, insomnia, decreased libido

■ Additional features supporting diagnosis: self-induced vomiting or purging, excessive exercise, use of appetite suppressants and/or diuretics

■ Biological complications

■ Neuroendocrine changes: amenorrhea, increased corticotropin-releasing factor, cortisol, growth hormone, serotonin; decreased diurnal cortisol fluctuation, luteinizing hormone, follicle-stimulating hormone, thyroid-stimulating hormone

■ Cardiovascular disorders: bradycardia, hypotension, arrhythmias, cardiomyopathy

■ Metabolic disorders: hypokalemia, hypochloremic metabolic alkalosis, increased BUN, edema

■ Other: dry skin, dental caries, delayed gastric emptying, constipation, anemia, osteoporosis

Bulimia Nervosa

■ Repeated binge eating followed by self-induced vomiting, misuse of laxatives, diuretics or other medications, fasting; or excessive exercise

■ Overeating at least twice a week during 3-month period; large amounts of food consumed in short period (~2 hrs)

■ Preoccupation with eating; craving and compulsion to eat; lack of control over eating; alternating with periods of starvation

■ Dread of fatness but may be obese

■ Purging: bulimic episodes accompanied by self-induced vomiting or use of laxatives, diuretics, or enemas

■ Nonpurging: bulimic episodes accompanied by compensatory behavior such as fasting, exercise but without purging.

■ Biological complications

See changes listed for anorexia nervosa, especially weakness, fatigue, mild cognitive disorder; also erosion of dental enamel, parotitis, pancreatic inflammation with elevated amylase, mild neuropathies, seizures, hypokalemia, hypochloremic metabolic acidosis, hypomagnesemia

Blood Pressure Health

Your heart pumps blood throughout your body using a network of tubing called arteries and capillaries which return the blood back to your heart via your veins. Blood pressure is the force of the blood pushing against the walls of your arteries as your heart beats.Learn more...
