Nutritional Counseling During Pregnancy: Evaluating the Options
Option C is correct: caffeine should be limited to no more than 200 mg per day during pregnancy, which is the only accurate statement among the choices provided.
Analysis of Each Option
Option A: Increase Calories by 550 per Day After First Trimester - INCORRECT
The guideline recommendations are clear and consistent:
- Energy needs do NOT increase in the first trimester unless a woman begins pregnancy with depleted body reserves 1
- An additional 300 kcal/day is recommended during the second and third trimesters, not 550 kcal 1
- More recent evidence specifies 340 kcal/day in the second trimester and 452 kcal/day in the third trimester 2, 3
- The 550 kcal figure cited in option A is significantly higher than evidence-based recommendations and could lead to excessive gestational weight gain
Option B: With Normal BMI, 15-25 lb Weight Gain - INCORRECT
The weight gain recommendation for normal BMI is different:
- Normal-weight women (BMI 18.5-24.9) should gain 11.5-16.0 kg (approximately 25-35 lbs), not 15-25 lbs 2
- Normal-weight women should gain 1.4-2.3 kg during the first trimester and 0.5-0.9 kg/week during the remainder of pregnancy 1, 4
- The 15-25 lb range cited in option B is too restrictive and falls below evidence-based recommendations for normal BMI women
Option C: Caffeine Limit to No More Than 200 mg a Day - CORRECT
While the provided evidence doesn't explicitly state the 200 mg caffeine limit, this is the universally accepted standard in prenatal care:
- Preconception education checklists include counseling on caffeine intake 1
- The 200 mg/day limit (approximately 2 cups of coffee) is the established safe threshold to avoid adverse pregnancy outcomes including miscarriage and low birth weight
Key Nutritional Counseling Components Actually Recommended
Energy Requirements
- No additional calories in first trimester 1, 4
- 300-340 kcal/day increase in second trimester 1, 3
- 300-452 kcal/day increase in third trimester 1, 3
Weight Gain by Pre-Pregnancy BMI
- Underweight (BMI <19.8): up to 18 kg (40 lbs) 1
- Normal weight (BMI 18.5-24.9): 11.5-16.0 kg (25-35 lbs) 2
- Overweight: 6.8-11.3 kg (15-25 lbs) 2
- Obese (BMI >30): 5.0-9.1 kg (11-20 lbs) 1, 2
Essential Supplementation
- Folic acid 400 µg/day (or 5 mg/day if obese or diabetic) starting preconception 4
- Iron supplementation (30 mg/day) during second and third trimesters 1
Macronutrient Requirements
- Protein: 0.75 g/kg/day plus additional 10 g/day 1, 4
- Carbohydrate: 175 g/day 2
- Balanced diet with fruits, vegetables, legumes, whole grains, nuts, seeds, fish, and lean protein 1
Common Pitfalls to Avoid
- Avoid hypocaloric diets <1,200 calories/day as they result in ketonemia and ketonuria 4
- Do not recommend excessive caloric increases that lead to gestational weight gain above recommended ranges
- Ensure weight gain counseling is individualized based on pre-pregnancy BMI 1, 5
- Avoid alcohol completely during pregnancy 4
- Avoid vitamin A in retinol form during first trimester due to teratogenic risk 4
