Nutrient Density Comparator

Why do many processed foods have a low nutrient density? Nutrient density is the relationship between calories and the nutritional quality of the food. A food with low nutrient density provides few nutrients per calorie. Many of highly processed foods such as fast food and candy contain large amounts of carbohydrates and fats. Carbohydrates are inexpensive to produce and both fats and sugars are highly appealing to most people. Therefore many processed foods, particularly inexpensive processed food are rich in fats and simple carbohydrates. They contain relatively few of the other nutrients included in our diets. Nutrients such as vitamins and trace elements are, in some cases, found in relatively restricted sets of unprocessed foods and are not often found in large amounts in processed foods unless a specific effort has been made to enhance nutritional quality.
