To explain: Whether Person L is consuming enough protein.

Person L is a 32-year-old healthy woman who follows a vegan diet since the age of 16. She consulted a dietician during her thirteenth week of pregnancy to discuss about 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 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 on 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.

There is an established set of guidelines under Dietary Reference Intake (DRI) to support the nutritional requirement of pregnant women. As per recommendations, the daily dietary allowance of proteins required by a pregnant woman is 71g, which is met by Person L as per her dietary evaluation. Therefore, it can be said that she is consuming enough proteins in her diet.
