Healthy Eating During Pregnancy
Pregnancy is the most
nutritionally demanding time of a woman's life. Your body needs enough
nutrients every day to support the growth of your baby. The Food Guide
Pyramid for Pregnant Women helps you choose foods for both your needs.
A pregnant woman needs about 300 calories a day more than she did
pre-pregnancy to support the rapid growth of the fetus and her changing
body. (Pre-pregnancy needs are about 2,200 calories daily for most
active women and teenage girls and about 1,600 calories for sedentary
women.)
Weight gain during pregnancy should be gradual with the most weight
being gained in the last trimester. According to the ACOG, you should
gain about 2 to 4 pounds during the first three months of pregnancy and
then 3 to 4 pounds per month for the rest of your pregnancy. Total
weight gain should be about 25 to 30 pounds. This will decrease the risk
of delivering a low-birth-weight baby. The Institute of Medicine
recommends that women who have a low Body Mass Index (BMI) - the ration
of weight to height - should gain 28 to 40 pounds during pregnancy and
women who have a higher BMI should gain 15 to 25 pounds.

of Health and Human Services.

Read juice labels.
Many drinks that seem to be fruit juices are really drinks that have
littler no fruit juice. Since fruit-type drinks are mostly sugar, they
do not count as a serving. Remember, fresh fruits and dried fruits have
more fiber than fruit juice, so they are better choices.

Nutritional Supplements
Prenatal
Vitamins:
Prenatal vitamins are fortified with Folate and are available
over-the-counter (OTC) or by prescription. If you have severe nausea or
are unable to take the vitamins, you can purchase 400 mcg of folic acid
by itself. There is no data that after the first trimester prenatal
vitamins are beneficial.
Folic Acid or Folate:
Folate is a "B" vitamin that may lower the incidence of neural tube
defects in your growing baby. You need 400 mcg of Folate daily. Over
the counter prenatal vitamins contain 400 - 800 mcg of folic acid while
prescription vitamins contain 1000 mcg. of Folate. Foods rich in folic
acid include beans, lentils, peanuts, sunflower seeds, walnuts, almonds,
orange juice, pineapple, cantaloupe, bananas, avocados, broccoli,
asparagus, spinach, dark green lettuce and okra. Many cereals and
breads may be fortified with Folate. The nutrition label on the foods
should list any supplements.
Iron Metabolism:
For good health, it is important that you
eat a balanced and varied diet. If you think that you are not getting
enough iron in your diet or you become anemic, you should take an iron
supplement. Iron is found in the diet in two forms - heme iron, which is
well absorbed, and non-heme iron, which is poorly absorbed. The best
dietary source of absorbable (heme) iron is lean red meat. Chicken,
turkey, and fish are also sources of iron, but they contain less than
red meat. Cereals, beans, and some vegetables contain poorly absorbed
(nonheme) iron. Foods rich in vitamin C (e.g., citrus fruits and fresh
vegetables), eaten with small amounts of heme iron-containing foods,
such as meat, may increase the amount of nonheme iron absorbed from
cereals, beans, and other vegetables. Some foods (e.g., milk, eggs,
spinach, fiber-containing, coffee, tea) may decrease the amount of
nonheme iron absorbed from foods. Additional iron may be added to food
from cooking in iron pots.

Iron Supplements:
A blood count will be drawn during your pregnancy at the first visit and
again in the third trimester to determine whether you have an iron
deficiency anemia. To
prevent deficiency, adult pregnant women should ingest 30mg iron per
day. Breast-feeding women should ingest 15 mg per day. To treat a
deficiency, take the amount prescribed by your physician or on the
manufacturer's package directions. Iron is best absorbed when taken on
an empty stomach, with water or fruit juice about 1 hour before or 2
hours after meals. However, to lessen the possibility of stomach upset,
iron may be taken with food or immediately after meals.
Do not take iron supplements and antacids or calcium supplements at the
same time. Iron supplements can be
purchased without a prescription. The different preparations may be
ferrous sulfate, ferrous gluconate or ferrous fumerate. Your body will
absorb only a small amount each day so any of these preparations is
adequate for iron supplementation. Some iron preparations contain
vitamin C, which increases iron absorption or a stool softener if you
have problems with constipation. If you are anemic and taking more than
one iron tablet per day, separate the times that you take it. Please see
the
http://ods.od.nih.gov/factsheets/iron.asp#h8 for more information on
iron sources in your diet and supplementation.
Ferrous sulfate is the least expensive iron with the most side
effects. Many people complain of constipation while on iron
supplementation. Of each 300 mg tablet of ferrous sulfate, only 60 mg
of iron is available for absorption. Ferrous gluconate contains only 36
mg of iron so it is less likely to cause stomach upset. The best iron
is ferrous fumarate which contains 66 mg of iron per 200 mg tablet with
the most bio-available iron for absorption. Ferrous Fumarate is more
expensive but is milder in terms of side effects.
Calcium:
The recommended daily allowance during pregnancy is 1000 mg daily.
Supplements can be purchased without a prescription at your pharmacy.
Calcium carbonate gives you the largest percentage of usable calcium and
should be taken with meals. Calcium citrate should be taken between
meals for best absorption. There is no difference between most generic
calcium supplements. TUMS or Viactiv Chews are both excellent methods
of supplementation.
Dietary Sources of Calcium
Pregnant and lactating women
need 1000 mg/day of calcium. Most of the calcium in the body is found in
the bodys bones and teeth. One percent circulates in the blood to
enhance nerve conduction, muscle contraction and blood clotting. If
nutritional calcium intake is not adequate, calcium is taken from the
bone to maintain blood calcium levels and osteoporosis may occur.

Calcium Supplements:
Calcium carbonate gives you the largest percentage of usable calcium.
Calcium carbonate should be taken with meals or snacks to increase
absorption. Calcium absorption is dependent on an adequate level of
vitamin D. Supplementation is not usually necessary because vitamin D is
added to fortified milk and occurs in fish and eggs. It also occurs
naturally in the skin by sunlight exposure 10 minutes/day. If you have
a history of kidney stones or if calcium carbonate causes gas or
constipation, try calcium citrate. Calcium citrate should be taken
between meals for best absorption. Please download a list of
calcium sources and supplements.
Other food sources
of calcium are fortified breads and cereals. High fat dairy products
should be avoided. Foods are the best source of usable calcium. Recent
evidence indicates that calcium from supplements interferes with
manganese, iron and thyroid medication absorption. Calcium from foods
does not have that detrimental effect. Take calcium supplements under
the supervision of your physician or a registered dietitian. If you are
unable to obtain all the necessary calcium from foods, a combination of
foods and a moderate amount of supplement may be the best therapy.
Hot tubs and Saunas:
Studies have shown that there is an increased incidence of miscarriage
if a sauna is used during the first three months of pregnancy. We
recommend against using the sauna during the entire pregnancy and not
using a hot tub during the first three months of pregnancy. After the
first three months of pregnancy, limit the hot tub to 100 degrees
temperature. The danger to the fetus appears to be from raising the
mother's core body temperature. Warm baths and showers are safe
throughout pregnancy.
Caffeine:
Caffeine should be limited to less than 300 mg/day.

Herbal supplements:
We do not recommend any herbal
supplements during the pregnancy. Most have not been studied so no
safety record is available. If you are taking a supplement, please
bring it to your appointment and discuss its use with your physician.
Exercise:
We encourage you to continue your normal exercise routine. There is no
longer a recommendation regarding maximum heart rate or pulse while
exercising. If you can speak normally, you have an acceptable heart
rate. We advise 30 minutes of moderate exercise on most, if not all,
days. Be careful to not injure yourself during the later part of
pregnancy when your balance changes and your ligaments loosen. DO NOT
EXERCISE if you have bleeding, cramping, abnormal pain or other high
risk factors relating to the pregnancy. Soccer, ice hockey, skiing,
horseback riding and water skiing are strongly discouraged due to risk
of falling. Scuba diving is not safe at any time during pregnancy. You
can download the ACOG bulletin on exercise during pregnancy.
http://www.acog.org/publications/patient_education/bp119.cfm
Alcohol:
Fetal Alcohol Syndrome (FAS) is the leading known cause of mental
retardation. It is preventable. Please DO NOT drink during your
pregnancy or use any illicit drugs such as amphetamines, cocaine,
marijuana, or hallucinogenic drugs.
Smoking:
Smoking while pregnant increases the incidence of low birth weight
babies, placental abruption, miscarriage, and pre-term labor. It also
increases your baby's risk for future ear infections, frequent colds and
SIDS. Please do not smoke during your pregnancy.
Dental Work:
Local anesthesia injections are safe. Use a lead apron if X-rays are
necessary. Pain medications and most antibiotics are safe (your dentist
will prescribe correctly). Ampicillin and Lidocaine are safe.
