Abstract Nutrition during pregnancy can induce alterations in offspring phenotype. Maternal ratio of protein to non-protein P:NP energy has been linked to variations in offspring body composition and adult risk of metabolic disease. This study describes the dietary patterns of pregnant women by tertiles of the P:NP ratio and compares diet to Australian recommendations. Data are from 179 Australian women enrolled in the Women and Their Children’s Health Study. Diet was assessed using a validated 74-item food frequency questionnaire. Food group servings and nutrient intakes were compared to the Australian Guide to Healthy Eating and Australian Nutrient Reference Values. Higher maternal P:NP tertile was positively associated with calcium P = 0.003, zinc P = 0.001 and servings of dairy P = 0.001 and meat P = 0.001 food groups, and inversely associated with the energy dense, nutrient poor non-core P = 0.003 food group. Micronutrient intakes were optimized with intermediate protein 18%E–20%E, intermediate fat 28%E–30%E and intermediate carbohydrate 50%E–54%E intakes, as indicated in tertile two. Results suggest a moderate protein intake may support pregnant women to consume the largest variety of nutrients across all food groups. View Full-Text
