Nutritional Guidelines for Pregnant Woman

U.S. Department Of Agriculture Food Pyramid

Food Group Recommendations

Because not all foods in a food group are created equal, the U.S. Department of Agriculture makes the following recommendations for choosing foods within a food group.

Grains

  • Make half your grains whole. Eat at least 3 oz of whole-grain cereals, breads, crackers, rice, or pasta every day;
  • 1 oz is about 1 slice of bread, about 1 cup of breakfast cereal, or 1/2 cup of cooked rice, cereal, or pasta.

Vegetables

  • Vary your veggies;
  • Eat more dark-green veggies like broccoli, spinach, and other dark leafy greens;
  • Eat more orange veggies, like carrots and sweet potatoes;
  • Eat more dry beans and peas like pinto beans, kidney beans, and lentils.

Fruits

  • Focus on fruits;
  • Eat a variety of fruit;
  • Choose fresh, frozen, canned, or dried fruit;
  • Go easy on fruit juices.

Milk

  • Consume calcium-rich foods;
  • Go low-fat or fat-free when you choose milk, yogurt, and other milk products;
  • If you don't or can't consume milk, choose lactose-free products or other calciums sources, such as fortified foods and beverages.

Meats and Beans

  • Go lean with protein;
  • Choose low-fat or lean meats and poultry;
  • Bake it, broil it, or grill it.
  • Vary your protein routine; choose more fish, beans, nuts, and seeds
For a 2,000 calorie diet, you need the amounts below from each food group:

Grains:                   Eat 6 oz every day
Veggies:                 Eat 2 1/2 cups every day
Fruits:                    Eat 2 cups every day
Milk:                      Get 3 cups every day; for kids ages 2 to 8 years, 2 cups
Meats and Leans:   Eat 5 1/2 oz every day

Find you balance between food and physical activity

  • Be sure to stay within your daily calorie needs;
  • Be physically active for at elast 30 minutes most days of the week;
  • About 60 minutes a day of physical activity may be needed to prevent weight gain;
  • For sustaining weight loss, at least 60 to 90 minutes a day of physical activity may be required;
  • Children and teenagers should be physically active for 60 minutes every day, or most days.

Know the limits on fats, sugars, and salt (sodium)

  • Make the most of your fat sources from fish, nuts, and vegetable oils;
  • Limit solid fats like butter, stick margarine, shortening, and lard, as well as foods that contain these;
  • Check the Nutritional Facts label to keep saturated fats, trans fats, and sodium low;
  • Choose food and beverages low in added sugars. Added sugars contribute calories with few, if any, nutrients.

Health Nutrition for Pregnant Mother

Healthy Mother

Nutrition During Pregnancy

Calories

  • Requirement exceeds pre-pregnancy needs by 300 calories per day (from 2,200 kcal/day to 2,500 kcal/day)
    • To support maternal-fetal tissue synthesis;
    • To meet increased basal metabolic needs;
    • To provide optimal use of protein and tissue growth

Proteins

  • Requirement exceeds pre-pregnancy needs by 14 to 16 grams per day (from 44 to 46 g/day to 60 g/day)
    • For expansion of blood volume;
    • For tissue growth'
    • For adequate amino acid intake for fetal development

Fats

  • 20% to 35% of woman's daily calorie intake
  • Linoleic acid
    • Essential for new cell growth;
    • Must be supplied by the diet;
    • Found in vegetable oils, such as corn, olive, peanut, and safflower oils.

Vitamins

  • Intake of all vitamins should be increased
    • Necessary for tissue synthesis and energy production;
    • Requirements for fat and water soluble vitamins increase
  • Intake of varied, healthy diet usually supplies the requirement for all of the vitamins except folic acid;
  • Folic acid is particularly important;
    • Promotes fetal growth and prevents anemia;
    • Intake should be increased from 400 to 800 mcg/day;
    • Sources include green, leafy vegetables, eggs, milk, and whole-grain bread.

Minerals

  • Intake of all minerals should be increased, including iodine, calcium, phosphorus, and zinc;
  • Drinking fluoridated water is important to aid in tooth formation; if fluoridated water is unavaiblable, a fluoride supplement should be prescribed;
  • The average American diet does not provide enough iron to prevent iron deficiency anemia; recommended supplemental iron intake is 30 to 60 mg per day.
  • Sodium restrictions is no longer advocated because it has been associated with hormonal and biochemical changes;
    • The National Research Council (NRC) recommends an increase in daily sodium intake of 69 mg over the normal dietary requirment of 2,400 mg;
    • Excessive sodium may lead to hypertension by altering fluid and electrolyte balance.

Developmental Tasks of Pregnancy

Acceptance of Pregnancy

General Characteristics

Depending on the woman's age, tasks may include acceptance and comfort with body image, development, of a personal value system, adjustment to an adult identity, and internalization of sexual role and identity. Other tasks include acceptance of pregnancy's termination at the time of the delivery and the maternal role, and resolution of fears about childbirth and bonding. The woman's partner also achieves these same developmental tasks.

First trimester: Acceptance of the Pregnancy

  • Pregnancy confirmation may leave some couples with disbelief, shick, or amazement;
  • The woman and her partner must learn to accept the reality of the pregnancy;
  • Most couples experience some degree of ambivalence;
  • Feeling the fetus move or seeing the fetus on an ultrasound can help the couple achieve acceptance; and
  • In accepting the pregnancy, the partner also accepts the woma as she undergoes he changes associated with pregnancy.

Second Trimester: Acceptance of the Baby

  • The woman and her partner work to accept the baby;
  • Acceptance of the baby refers to acknowledgement that the fetus is a distinct individual, separate from another;
  • Feeling the fetus move or hearing its heart beat demonstrates that the fetus is an active being;
  • Anticipatory role playing, for example with the woman or partner imagining the type of parent she or he will be, may occur;
  • The woman and her partner begin active preparations for the baby; and
  • The partner may feel left out with all the information being focused on the woman and fetus; time is needed to ensure that the partner is given the information and support required.

Third Trimester: Preparation for Parenthood

  • The couple work on preparing to become parents;
  • The couple begin to demonstrate "nesting" behavior, such as preparing the baby's room, shopping for necessary baby items, and discussing names;
  • The couple may attend the childbirth education classes; and
  • The couple may review relationships with their own parents and engage in role-playing and fantasizing about being a parent.

Normal Pregnancy

Pregnant Mother

Overview of the trimesters of pregnancy

First Trimester (1st - 3rd month)

  • Lasts from weeks 1 through 12 and is a critical time in the pregnancy;
  • Rapid cell differentiation makes the developing embryo or fetus highly susceptible to the teratogenic effects of viruses, alcohol, cigarettes, caffeine, and other drugs;
  • The woman usally experiences physical changes, such as amenorrhes (absence of menstruation), urinary frequency, nausea and vomiting (more severe in the morning or when the stomach is empty), breast swelling and tenderness, fatigue, increased vaginal secretions, and constipation;
  • 7 to 10 days after conception, a serum pregnancy test can usaully detect the presence of human chorionic gonadotropin (hCG);
  • A pelvic examination, performed 6 to 8 weeks later, shows uterine enlargement, Chadwick's sign, and Hegar's sign.

Second Trimester (4th - 6th month)

  • Lasts from weeks 13 through 27;
  • Uterine and fetal size increase substantially;
    • The woman gains weight, the waistline thickens, and the abdomen enlarges;
    • Reddish streaks (striations) may become apparent as abdominal skin stretches;
    • Pigment changes may cause skin alterations, such as linea nigra, melasma (mask of pregnancy) and a darkening of the areola of the nipples;
    • Other physical changes include diaphoresis (massive perspiration), increased salivation, indigestion, continuing constipation, hemorrhoids, nosebleeds, and some dependent edema;
    • The breast become larger and heavier, and about 19 weeks after the last menses they may secrete colostrum.
  • By week 20, the fetus is large enough for the mother to feel its movement (quickening).

Third Trimester (7th - 9th month)

  • Lasts from weeks 28 through 40;
  • The woman experiences Braxton Hicks contractions - sporadic episodes of painless uterine tightening - which help strengthen uterine muscles in preparation for labor;
  • Increasing uterine size may displace pelvic and intestinal structures, causing indigestion, protrusion of the umbilicus, shortness of breath and insomnia;
  • The woman's center of gravity changes; she may experience backaches beacuse she walks with a swaybacked posture to counteract the frontal weight.
