Position of the Academy of Nutrition and Dietetics: Use of Nutritive and Nonnutritive Sweeteners S WEETENERSCANBEGROUPEDIN variousways.Forthepur- pose of this article swee- teners will be grouped as nutritive and nonnutritive. Nutritive sweeteners contain carbohydrate and provide energy; they may be further classif i ed into monosaccharides or di- saccharides, which impart 4 kcal/g, or sugar alcohols (polyols), which provide an average of 2 kcal/g (1). Different terms are used to refer to nutritive sweeteners, including sugars, sugar, ca- loric sweeteners, and added sugars. Sug- ars occur naturally (intrinsic) in all fruit, vegetables, and dairy foods or are added (extrinsic) to foods during pro- cessing, or in preparation for consump- tion by an individual (2). Sugars commonly found in foods in- clude: •Glucose A monosaccharide and the primary source of energy for body cells. •FructoseAmonosaccharide found in fruit, honey, and some vegetables. In nature, it is linked with glucose as the disaccharide sucrose. Fructose may be used as a nutritive sweetener. •GalactoseAmonosaccharide that occurs in dairy products and some plants. •Sucrose A disaccharide that oc- cursnaturallyinfruitandvegeta- bles. It is composed of approxi- mately equal parts glucose and fructoseandisusedasanutritive sweetener and for its other func- tional properties. •Maltose A disaccharide com- posed of two glucose units; it is found in molasses and is used for fermentation. •Corn-based sweetener Refers to many products made from corn. Theymaybecomposedprimarily of glucose, fructose, or any com- bination of the two. High-fruc- tose corn syrup (HFCS) is a mix- ture of glucose and fructose and is only available to food manu- facturers. •Agave nectar A nutritive sweet- ener that contains fructans, oli- gosaccharides of fructose and glucose, and monosccharides of fructose and glucose. Sugar often refers to sucrose, which is derived from sugar cane or sugar beets. TheUSDepartmentofAgriculture (USDA) uses added sugars to refer to sugars and syrups added to foods dur- ing processing, preparation or before consumption. In addition to imparting asweettaste,sugarshavethefollowing functions that are important to safety and quality in foods: •Inhibitmicrobialgrowthby binding water in jams and jellies. ABSTRACT It is the position of the Academy of Nutrition and Dietetics that consumers can safely enjoy a range of nutritive sweeteners and nonnutritive sweeteners (NNS) when con- sumed within an eating plan that is guided by current federal nutrition recommenda- tions,suchastheDietaryGuidelinesforAmericansandtheDietaryReferenceIntakes,as well as individual health goals and personal preference. A preference for sweet taste is innateandsweetenerscanincreasethepleasureofeating.Nutritivesweetenerscontain carbohydrateandprovideenergy.Theyoccurnaturallyinfoodsormaybeaddedinfood processing or by consumers before consumption. Higher intake of added sugars is asso- ciated with higher energy intake and lower diet quality, which can increase the risk for obesity, prediabetes, type 2 diabetes, and cardiovascular disease. On average, adults in the United States consume 14.6% of energy from added sugars. Polyols (also referred to as sugar alcohols) add sweetness with less energy and may reduce risk for dental caries. Foodscontainingpolyolsand/ornoaddedsugarscan,withinfoodlabelingguidelines,be labeled as sugar-free. NNS are those that sweeten with minimal or no carbohydrate or energy. They are regulated by the Food and Drug Administration as food additives or generally recognized as safe. The Food and Drug Administration approval process in- cludes determination of probable intake, cumulative effect from all uses, and toxicology studies in animals. Seven NNS are approved for use in the United States: acesulfame K, aspartame, luo han guo fruit extract, neotame, saccharin, stevia, and sucralose. They have different functional properties that may affect perceived taste or use in different food applications. All NNS approved for use in the United States are determined to be safe.
