Nutrient Density, Healthy Eating Patterns, and Dietary Guidelines
Skipping meals is never a good idea when one wants to eat a balanced diet, rich in vitamins and minerals. Lunch is an important source of nutrients for school-aged children. New data from 4,755 children and adolescents (NHANES 2009-2012) finds that missing lunch is associated with lower micronutrient intakes.
Within the US, 40% of children bring a packed lunch to school and packed lunches are of less nutritional quality than school lunches. Implementing nutrition standards for school lunches promotes dietary health. Unfortunately, Spence and colleagues found the gap in nutritional quality between packed lunches and school lunch is widening in the UK.
Breakfast skipping and selection of foods of low nutritional quality in the morning is common among school-age children regardless of economic status. To grow, to learn, and to be healthy, children need to eat foods that provide calories (carbohydrate, protein, fat) and are rich in vitamins, minerals, and other essential nutrients.
Nutrient dense foods are ones which contain more beneficial nutrients per calorie, sometimes volume or weight. The purpose of emphasizing nutrient density is to encourage people to improve the nutrient-to-energy ratio of their diet. Although the term nutrient density may be loosely defined, the Dietary Guidelines for Americans 2015 emphasizes the importance of healthy eating patterns (not skipping meals is a simple interpretation) and choosing a variety of nutrient-dense foods across all and within all food groups in recommended amounts. Sage advice.
