LO 14.9 Infants Have Specific Nutrient Needs
An infant doubles his or her birth weight by around 6 months of age, and triples it by 12 months. With proper nutrition, an infant should reach certain stages of physical development within a distinct time frame. Poor infant nutrition (whether in quality or quantity) will likely prevent ideal growth and the ability of the child to reach milestones on time. All infants should receive a vitamin K injection at birth, and breast-fed infants need vitamin D supplements until 1 year of age. Infants older than 6 months need to begin taking in iron through food sources, as their stored iron supply is depleted around this time.
LO 14.2 Specific Nutrients and Behaviors Are Important during the First Trimester
Healthy women who begin pregnancy at a healthy weight should gain 25 to 35 pounds during pregnancy. A woman's needs for many nutrients including folate, iron, zinc, copper, and calcium increase up to 50 percent during pregnancy. Care should be taken to avoid consuming too much preformed vitamin A, which can cause birth defects. Exercise during pregnancy can help improve sleep, lower the risk of hypertension and diabetes, prevent backaches, relieve constipation, shorten labor, reduce stress and depression, and possibly allow women to return more quickly to their prepregnancy weight after delivery. Awareness of food safety is also important, as bacteria such as Listeria monocytogenes may cause miscarriages, premature labor, delivery of a low birth weight infant, developmental problems, or even infant death. Pregnant women should abstain from alcohol, herbal teas and herbal supplements, and illicit drugs, as these can all harm fetal growth and development. They should avoid fish that contain high amounts of methylmercury and consume caffeine only in moderation.
LO 14.5 Younger and Older Mothers-to-Be Face Special Challenges
Women younger or older than the physically optimal childbearing age range of 20 to 35 may face additional challenges during pregnancy. Teenage mothers-to-be are at risk for pregnancy-induced hypertension, iron-deficiency anemia, and delivering premature and low birth weight babies. Older mothers-to-be are at risk of developing diabetes and high blood pressure. Their infants are more likely to have Down syndrome or other disabilities. Older women who use fertility-enhancing techniques are also more likely to give birth to multiples, which carries other increased risks, including premature birth, labor difficulties, and low birth weight.
LO 14.4 4. During the third trimester of pregnancy, a woman who begins pregnancy at a healthy weight should increase her daily calorie intake by 450 calories a day. 340 calories a day. 500 calories a day. No increase is needed.
(a) A pregnant woman at a healthy weight before pregnancy needs 450 more calories than her prepregnancy energy needs every day during the third trimester. She doesn't require additional daily calories during the first trimester, but does have additional nutrient needs, so she should be sure to eat nutrient-rich foods. During the second trimester, she needs an extra 340 calories every day.
LO 14.9 9. Andy is a healthy 3-month-old baby boy who is being breast-fed by his mother. Which of the following nutrients should be added to his diet in supplement form? vitamin D potassium vitamin C omega-3 fats
(a) Although breast milk is an ideal food for baby Andy, it doesn't contain enough vitamin D, so Andy should receive daily drops in his diet. He doesn't need to be supplemented with vitamin C, potassium, or omega-3 fats.
LO 14.8 8. The best alternative to breast-feeding is to feed an infant with commercially made formula. cow's milk. soy or almond milk. pureed baby food.
(a) The best alternative to breast-feeding is commercially made formula. Cow's milk should not be used to feed infants because it is more difficult to digest than formula or breast milk.
LO 14.3 3. Two potential complications of pregnancy that must be closely monitored by a health care provider are cravings and morning sickness. gestational diabetes and preeclampsia. weight gain and exercise. constipation and heartburn.
(b) Gestational diabetes and preeclampsia are both potentially life-threatening complications that can be brought on by pregnancy and should be closely monitored by a physician. Cravings, morning sickness, constipation, and heartburn can all occur during pregnancy, but are not considered serious unless they are severe. Weight gain and exercise are not complications of pregnancy.
LO 14.2 2. To support the birth of a healthy 6.5- to 8.5-pound baby, how many pounds should a normal-weight woman gain during pregnancy? 10 to 15 pounds 25 to 35 pounds 15 to 25 pounds 37 to 54 pounds
(b) Women who begin pregnancy at a healthy weight should gain from 25 to 35 pounds. This is the approximate amount of weight needed to ensure a healthy-weight baby while avoiding the risks of carrying excess weight.
LO 14.6 6. Breast-feeding cannot help women reduce their risk of breast cancer. reduce women's risk of type 2 diabetes. prevent pregnancy. decrease the risk of the baby developing respiratory and ear infections.
(c) Breast-feeding provides health advantages to both the mother and the baby. Breast-feeding reduces the risk of breast cancer and diabetes in the mother and the incidences of respiratory and ear infections in the baby. Breast-feeding cannot be relied upon to prevent pregnancy, however.
LO 14.10 10. Six-month-old Cathy is ready to take on solid foods. One healthy and safe first food that could be introduced in her diet is chopped meat. ready-to-eat crunchy cereal. iron-fortified rice cereal. scrambled eggs.
(c) Iron-fortified rice cereal is a good choice and is unlikely to cause an allergic reaction. If Cathy tolerates the rice cereal well, oatmeal could be the next grain added to her diet, or she could try pureed meats, which are rich in iron.
LO 14.1 1. To prevent neural tube birth defects, a woman should take 400 micrograms of folic acid daily during the first trimester. during the second trimester. throughout her childbearing years, if she's capable of conceiving. during the last trimester.
(c) To reduce the risk of these birth defects, folic acid should be consumed prior to conception and continue during the early weeks of pregnancy. Waiting until pregnancy occurs may be too late to help prevent birth defects during the first trimester. Because pregnancy increases the need for this vitamin, the mother should continue to make sure that folate intake is adequate throughout her pregnancy.
LO 14.5 5. During pregnancy, a teenage mother's need for many nutrients increases. Which nutrient requirement is unlikely to be met through her diet alone? iron folic acid calcium all of the above
(d) A teenage girl's body is still growing, so she has higher nutrient needs than does an adult woman. Pair these higher needs with the increased needs of pregnancy, and these young mothers are likely to fall short of many of their nutrient requirements, especially iron, folic acid, calcium, and potentially even calories.
LO 14.7 7. A breast-feeding mother should limit her intake of which of the following? fish, especially deep-sea fish high in mercury caffeine alcohol all of the above
(d) Anything that goes into a breast-feeding mother's body can potentially pass into her breast milk. Mothers should avoid exposure to deep-sea fish, limit caffeine to no more than three cups per day, and limit alcohol intake to an occasional drink, if any at all.

LO 14.1 Nutrient Intake and Healthy Behaviors Impact Fertility
Both the father and the mother should make healthy diet and lifestyle changes if needed prior to pregnancy. For healthy sperm, men should stop smoking, abstain from alcohol or drink only in moderation, strive for a healthy body weight, and consume a well-balanced diet with adequate amounts of fruits and vegetables, whole grains, lean meats, low-fat dairy foods, and legumes. Prior to pregnancy, women should also abstain from alcohol, smoking, and caffeine, and strive for a healthy weight. In addition, women should consume adequate amounts of folic acid prior to conception to reduce the risk of neural tube defects.
LO 14.6 Breast-Feeding Benefits Both Mother and Child
Breast-feeding is the gold standard for feeding an infant. It provides physical, emotional, convenience, and financial benefits for the mother and nutritional and health benefits for the infant. Breast milk is rich in nutrients, antibodies, and other compounds that provide the infant with a disease-fighting boost until the baby's own immune system matures. Because of all the benefits, women are encouraged to exclusively breast-feed for the first six months. Breast-feeding women can also express their breast milk with a pump and store it for later use, allowing for more flexibility in their schedules.
LO 14.7 Breast-Feeding Mothers Have Increased Nutrient Needs
Breast-feeding mothers who began pregnancy at a healthy weight need to consume 330 to 400 extra calories daily to produce breast milk, and a breast-feeding woman should drink about 13 cups of water and beverages daily. Anything that goes into a breast-feeding mother's body can potentially pass into her breast milk, so she should limit caffeine consumption and discuss alcohol and medication intake with her health care provider. Breast-feeding mothers should also be careful to avoid overconsumption of fish that may contain methylmercury.
LO 14.4 Healthy Eating Behaviors and Weight Gain Are Important Considerations during the Third Trimester
By the end of the last trimester, a pregnant woman should be taking in an extra 450 calories daily and continue to gain about 1 pound per week. The slower movement of food through the GI tract can contribute to heartburn and constipation. Reduced physical activity and iron supplementation can also contribute to constipation. To minimize heartburn, pregnant women should eat smaller but frequent meals, eliminate spicy foods that may irritate the esophagus, and avoid lying down immediately after meals. Exercise and consuming fiber-rich foods, along with plenty of fluids, can help prevent or alleviate constipation.
67) Breast milk must be consumed directly from the mother's breast because otherwise it degrades too quickly.
F
75) Food allergy and food intolerance are two terms for the same condition.
F
Commercial baby food is always less healthy than homemade.
FALSE. Although there's probably nothing as delicious and fresh as homemade, most brands of jarred baby foods are just as healthy. Read more about commercially made versus homemade baby foods on page 554.
Raw carrots are a safe food for infants to help meet their need for vitamin A.
FALSE. Although they're a good source of vitamin A and other nutrients, raw carrots are a potential choking hazard for an infant. For more on potentially dangerous foods, turn to page 555.
Drinking red wine is healthy during pregnancy.
FALSE. Any type of alcohol, including red wine, can harm a growing embryo and fetus. To find out what other substances can be harmful during pregnancy, turn to page 537.
Infant formula is better for babies than breast milk.
FALSE. Infant formula is a healthy alternative, but breast milk is best for a baby. Turn to page 543 to find out why.
Chubby babies should be put on diets.
FALSE. Infants should never be put on a weight-loss diet. Babies need calories and fat to support their rapid growth and development. To find out more about the demands of infant growth, turn to page 552.
Morning sickness only happens before noon during the first trimester.
FALSE. Though it's called morning sickness, nausea can happen at any time of day, and sometimes occurs after the first trimester. To learn more about conditions during pregnancy, turn to page 533.
LO 14.8 Formula Can Be a Healthy Alternative to Breast Milk
If an infant isn't breast-fed, the only healthy alternative is commercially made formula. Commercially made formulas are modified from soy or cow's milk, and patterned after human breast milk. For some women, formula-feeding is a personal preference. For others it is necessary, as breast-feeding may not be possible due to illness or other circumstances. Tooth decay and ear infections can be prevented by avoiding bedtime bottle feedings when infants are placed in bed with a bottle.
LO 14.10 Solid Foods Should Be Introduced Gradually after Certain Milestones Are Reached
Infants need to be nutritionally, physiologically, and physically ready before they begin eating solid foods. Foods should be introduced gradually and one at a time to monitor possible allergies or intolerances. Certain foods can be dangerous and should be avoided. Parents and caregivers should avoid adding heavy seasoning (such as sugar or salt) and offering excess amounts of fruit juice (which can lead to overconsumption of calories) to an infant's diet.
LO 14.3 Additional Carbohydrates and Protein Are Important during the Second Trimester
Many pregnant women find that the nausea and fatigue of the first trimester diminish during the second trimester, and appetite begins to increase. The mother's calorie needs also increase. A pregnant woman should consume an additional 340 calories daily during the second trimester and should gain around a pound per week. Pregnant women need about 175 grams of carbohydrate and 71 grams of protein. These needs can be met with a balanced diet. Sometimes a woman develops gestational diabetes and/or hypertension during pregnancy. Gestational diabetes increases the risk of delivering a larger-than-normal baby who may also be at risk for developing jaundice, breathing problems, and birth defects. Pregnancy-induced hypertension includes gestational hypertension, preeclampsia, and eclampsia, each progressively more medically serious. The risk of gestational diabetes and hypertension can be reduced during the second trimester with a healthy diet, daily exercise, and managing body weight.
