Textbook Problem

Ms. Lederman, a healthy 32-year-old woman entering her thirteenth week of pregnancy, asks her doctor for a referral to a dietitian to discuss her vegan diet. She receives the referral, and while making an appointment with the nutrition consulting service, she is asked to record her food intake for 3 days prior to the appointment. Ms. Lederman follows the instructions she was given and carefully completes a 3-day food record. Prior to the appointment, she sends her food record to the dietitian she will be seeing.

  During the appointment, the dietitian learns that Ms. Lederman started pregnancy at normal weight, has gained 3 lb so far in pregnancy, has no history of iron or another nutrient deficiency, and is experiencing a normal course of pregnancy. Ms. Lederman has been a vegan since the age of 16, and although she believes it is good for her health, she worries that her baby may not be getting the nutrients she or he needs. Ms. Lederman wears sunscreen whenever she goes outside, so she makes little or no vitamin D in her skin. She makes sure to combine plant sources of protein (usually dried beans and grains), so she’ll consume complete sources of protein every day.

  Results of the dietary analysis performed by the dietitian showed the following average calorie and nutrient intake levels:

  Kcal: 2237

  Protein, g: 71

  Linoleic acid (n-6 fatty acids), g: 15.2

  Alpha-linolenic acid (n-3 fatty acids), g: 0.54

  Vitamin B12, mcg: 2.1

  Vitamin D, meg: 3 (120 IU)

  Zinc, mg: 15

2.    Based on the information presented, which nutrients are consumed in amounts that are below the DRI standard for pregnancy?

Summary Introduction

To determine: The nutrients that are consumed in lower amounts by Person L as per DRI standard for pregnancy.

Introduction: The diet of a pregnant woman influences her as well as her infant’s health. The amount of calories that a pregnant woman consumes depends on the amount of weight gain required. However, the nutrient intake is determined by the recommendations of Dietary Reference Intakes (DRI) and hence, an appropriate diet fulfilling the above recommendations should be taken.


Person L is a 32-year-old healthy woman who follows a vegan diet since the age of 16. She is in her thirteenth week of pregnancy and consulted a dietician to discuss her diet. A three day food record prior to the appointment was also presented to the dietician. The dietician interpreted that she gained 3 lb during pregnancy with no iron or nutrient deficiency and that she lacks vitamin D as she wears sunscreen whenever going outside. Person L also ensures to combine plant sources of protein, usually dried beans and grains in her diet. A detailed dietary analysis was then performed for her. Her average caloric intake is 2237 kcal and her nutrient intake levels were 71 g protein, 15.2 g linoleic acid, 0.54 g α linolenic acid, 2.1 mcg vitamin B12, 3 mcg vitamin D, and 15 mg zinc
