Nutrition for Childbearing

These flashcards cover key nutritional information and guidelines for childbearing, including recommendations for weight gain, necessary dietary adjustments, and specific food precautions during and after pregnancy.

Adequate Nutrition

Essential for supporting the health of both mother and fetus during pregnancy.

Weight Gain Recommendation

Total weight gain during pregnancy should be between 11.4-15.9 kg (25-35 lb).

Fetus Average Weight

The expected weight of the fetus at term is approximately 3.2-3.4 kg (7-7.5 lb).

Increased Calories in Pregnancy

Additional calorie intake required during each trimester: Second Trimester +340 calories, Third Trimester +452 calories.

Folic Acid

A crucial supplement needed during pregnancy to prevent neural tube defects.

Risk Factors for Inappropriate Nutrition

Factors include special diets, health conditions such as anemia, and personal choices.

Pica

An eating disorder characterized by cravings for non-food substances.

Breastfeeding Nutritional Needs

Breastfeeding mothers require an additional 500 calories for up to 6 months.

Food Precautions

Certain foods to avoid during pregnancy include shark, swordfish, and unpasteurized products.

Postpartum Weight Loss Expectations

Non-lactating mothers can expect to lose approximately 12 lb at birth and regain normal weight by 6 months.

An eating disorder characterized by cravings for non-food substances.

Breastfeeding Nutritional Needs

Breastfeeding mothers require an additional $500$ calories for up to $6$ months.

Food Precautions

Certain foods to avoid during pregnancy include shark, swordfish, and unpasteurized products.

Postpartum Weight Loss Expectations

Non-lactating mothers can expect to lose approximately $12 \text{ lb}$ at birth and regain normal weight by $6$ months.

Iron Supplementation

Required intake increases to $27 \text{ mg/day}$ to support the expansion of maternal red blood cell mass and fetal iron storage.

Protein Requirements

Recommended daily intake increases to $71 \text{ g/day}$ to support rapid tissue growth of the fetus and placenta.

Caffeine Limitation

Daily intake should be limited to $200 \text{ mg}$ or less to minimize risks of miscarriage or fetal growth issues.

Calcium Intake

Requirement remains at $1,000 \text{ mg/day}$ for women aged $19$ and older; it is vital for mineralization of fetal bones and teeth.

Fluid Consumption

Pregnant women should consume $8\text{-}10$ glasses ($2.3 \text{ L}$) of fluid daily, primarily water, to support exchange and waste

First Trimester Calorie Intake

During the first trimester, additional calorie intake is generally not required, and energy needs remain similar to pre-pregnancy levels.

Vitamin C and Iron Absorption

Consuming iron supplements with sources of Vitamin C, such as orange juice, enhances the absorption of iron.

Mercury Exposure Risks

Pregnant women should avoid large fish like shark, swordfish, and king mackerel because their high mercury content can damage the fetal nervous system.

Sources of Folic Acid

Key dietary sources include green leafy vegetables, orange juice, legumes, and fortified cereals or breads.

Sodium Intake during Pregnancy

Sodium should be consumed in moderation; it should not be severely restricted because it is essential for maintaining increased blood volume and fluid balance.

Vitamin B12 for Vegetarians

Pregnant women who follow a strict vegan or vegetarian diet may need B12 supplementation to support fetal neurological development.

Listeriosis Prevention

To avoid Lister

Listeriosis Prevention

To avoid Listeriosis, pregnant women should avoid unpasteurized milk and soft cheeses (e.g., feta, brie, camembert) and ensure deli meats are heated until steaming hot.

Weight Gain Pattern

During the first trimester, weight gain should be between $1.1\text{-}2.0 \text{ kg}$ ($2.2\text{-}4.4 \text{ lb}$), followed by approximately $0.4 \text{ kg}$ ($1 \text{ lb}$) per week for a person with a normal BMI.

Iron-Rich Food Sources

Recommended sources include red meats, iron-fortified cereals, beans, and dark leafy greens to help meet the increased demand of $27 \text{ mg/day}$.

Fiber and Constipation

Increasing dietary fiber to $25\text{-}28 \text{ g/day}$ and maintaining adequate fluid intake helps prevent constipation, a common discomfort during pregnancy.

Vitamin A Limitations

While necessary, excessive intake of preformed Vitamin A (retinol) should be avoided as high doses can be teratogenic (harmful to the fetus).

Calcium's Role in Fetal Development

Essential for the mineralization of fetal bones and teeth; the recommended intake is $1,000 \text{ mg/day}$ for women aged $19$ and older.

Why is sodium intake not restricted during pregnancy?

Sodium is essential for maintaining the body's increased blood volume and ensuring proper fluid balance.

Vitamin B12 supplementation for Vegan Mothers

Required for women on strict vegan or vegetarian diets to support the neurological development of the fetus.

Specific Fish to Avoid (Mercury Risk)

High mercury content in shark, swordfish, and king mackerel can damage the fetal nervous system and should be avoided.

Fiber Intake Recommendation

Consuming $25\text{-}28 \text{ g/day}$ of dietary fiber, along with adequate fluids, helps prevent pregnancy-related constipation.

Weight Gain Goal: Second and Third Trimesters

For a woman with a normal BMI, the target weight gain is approximately $0.4 \text{ kg}$ ($1 \text{ lb}$) per week.

Vitamin A Toxicity (Retinol)

Excessive intake of preformed Vitamin A (retinol) should be avoided because high doses can be teratogenic to the fetus.

Requirement for Red Blood Cell Expansion

Iron intake must increase to $27 \text{ mg/day}$ to support the expansion of maternal red blood cell mass and fetal iron storage.

Protein's Role in Pregnancy

Daily intake increases to $71 \text{ g/day}$ to support the rapid tissue growth of both
