In a recent study, published in The Journal of Nutrition, researchers from the National Institute of Health's Environmental Influences on Child's Health Outcomes Program set out to find a list of low-calorie, nutrient-rich foods to help boost nutrient intake without having to rely on supplements.
The team, led by Katherine Sauder from the Wake Forest University School of Medicine and Catherine Cohen from the University of Colorado Anschutz, used previous analysis of 2,450 pregnant women to determine how much of each of these six essential nutrients women were getting through their diets.
While there was no single food that could provide enough of all six nutrients in a reasonable serving size, several foods and beverages contained at least four key nutrients in reasonable serving sizes.
