Higher scores represent greater overall nutritional value. However, the actual algorithm, including the relative weights of the nutrients, was never disclosed to the public. [4] Broccoli, blueberries, okra, oranges, and green beans were some foods that received the best score (100) while ice pops and soft drinks received the worst (1). [1]
Dietary fiber is defined to be plant components that are not broken down by human digestive enzymes. [1] In the late 20th century, only lignin and some polysaccharides were known to satisfy this definition, but in the early 21st century, resistant starch and oligosaccharides were included as dietary fiber components.
The most important aspect and defining characteristic of protein from a nutritional standpoint is its amino acid composition. [2] Proteins are polymer chains made of amino acids linked together by peptide bonds. During human digestion, proteins are broken down in the stomach to smaller polypeptide chains via hydrochloric acid and protease actions.
Nutritional rating systems are used to communicate the nutritional value of food in a more-simplified manner, with a ranking (or rating), than nutrition facts labels.
