PLAZA-DIAZ, Julio; MARTINEZ AUGUSTIN, Olga  e  GIL HERNANDEZ, Ángel. Food as sources of mono and disaccharides: biochemical and metabolic aspects. Nutr. Hosp. [online]. 2013, vol.28, suppl.4, pp.5-16. ISSN 1699-5198.

Carbohydrates are important and necessary components of human diet. Although they primarily play an energetic function, they also have structural and functional roles. According to the European Food Safety Authority, carbohydrate intake should range between 45 and 60 percent of the energy in adults and children older than one year of age. An important part of carbohydrates available in foods are mono and disaccharides, commonly referred to as sugars. Dietary sources of sugars include fruits, fruit juices, vegetables, milk and milk products, and foods containing added sucrose and starch hydrolyzates. Despite their importance in daily life, there is currently no clear and adequate terminology on the various types of carbohydrates, particularly sugars. Nor are there available sugar intake recommendations or food composition tables. Without these recommendations or reference values, dietary unbalances might occur, which subsequently may end in the premature onset of most chronic or degenerative diseases of our society. The aims of the present work are: to classify dietary carbohydrates, to define the biochemical and common terms for sugars, to explain their nutritional value and their metabolism as well as their food sources and to carry out a SWOT (Strengths, Weaknesses, Opportunities, Threats) analysis about the nomenclature and dietary intakes of sugars.
