Sugar has never been considered a healthy food, but it has still become a major part of our diet. Whether sugar is simply a source of "empty calories" or something more sinister has been an ongoing debate among nutrition experts. Read on to learn all about sugar, the many ways it impacts health, and practical takeaways for decreasing your intake. Start your FREE 7-day trial!

When you hear the term "sugar," you probably think of white table sugar, or sucrose. In reality, there are a number of different types of sugar. Chemically, sugars are either single sugar molecules (monosaccharides) or, more commonly, two sugar molecules linked together (disaccharides).



These sugars occur naturally in many foods, and some types are also added to processed foods. Glucose: Glucose is the main sugar found in blood and one of your body’s major fuels. Food sources: fruit and fruit juice (especially bananas, cherries, dates, and oranges), beets, carrots, honey. Fructose: Fructose is sometimes referred to as "fruit sugar" because it’s found in many fruits. Food sources: fruit and fruit juice (especially apricots, grapes, pears, and watermelon), artichokes, sugar snap peas, honey, agave nectar. Sucrose: Sucrose contains one glucose molecule and one fructose molecule linked together.1 As a disaccharide, it is too large for your body to absorb. In your digestive tract, sucrose is broken down into glucose and fructose, which are absorbed separately into your bloodstream. Food sources: fruits, table sugar, molasses, coconut sugar, honey, maple syrup, and any foods or beverages that contain added sucrose. Lactose: Lactose contains one molecule of glucose and one molecule of galactose, another monosaccharide. It is the main sugar found in dairy foods. Similarly to sucrose, lactose is broken down into its monosaccharide components so that they can be absorbed into your bloodstream. Food sources: milk, buttermilk, yogurt, ricotta cheese, cottage cheese, sour cream, whey. Maltose: Maltose contains two glucose molecules linked together. It results from the breakdown of starch (a long chain of glucose molecules) in your digestive tract. In addition, it’s increasingly being used in place of high-fructose corn syrup in processed foods. Because your body breaks down maltose into two glucose molecules which are absorbed directly into your bloodstream, consuming starchy foods and beverages can raise blood sugar considerably even though they don’t taste sweet.2 Food sources: potatoes, sweet potatoes, corn, bread, pasta, beer, some breakfast cereals, processed foods.



Finest grades - Powdered sugar, confectioner's sugar (0.060 mm), or icing sugar (0.024 mm), are produced by grinding sugar to a fine powder. A small amount of anti-caking agent to prevent clumping may be added, GlucoLife Official this is either cornstarch (1%-3%) or tri-calcium phosphate. There are also sugar cubes for convenient consumption of a normal amount. Brown sugars are obtained in the late stages of sugar refining, when sugar forms fine crystals with significant molasses content, or by coating white refined sugar with a cane molasses syrup. Their color and taste become stronger with increasing molasses content, as does their moisture retaining properties. They are also prone to hardening if exposed to the atmosphere although this is reversible. Sucrose is a disaccharide of glucose (left) and fructose, GlucoLife Official important molecules in the body. In biochemistry, a sugar is the simplest molecule that can be identified as a carbohydrate. These include monosaccharides and disaccharides, trisaccharides and the oligosaccharides; these being sugars composed of 1, 2, 3 or more units.



O), where there are carbon-oxygen double bonds, making the sugars reactive. Most sugars conform to (CH2O)n where n is between 3 and 7. A notable exception is deoxyribose, which as the name suggests is "missing" an oxygen. As well as being classified by their reactive group, sugars are also classified by the number of carbons they contain. Derivatives of trioses (C3H6O3) are intermediates in glycolysis. Pentoses ( 5 carbon sugars) include ribose and deoxyribose, which are present in nucleic acids. Ribose is also a component of several chemicals that are important to the metabolic process, including NADH and ATP. Hexoses ( 6 carbon sugars) include glucose which is a universal substrate for the production of energy in the form of ATP. Through photosynthesis plants produce glucose which is then converted for storage as an energy reserve in the form of other carbohydrates such as starch, or as in cane and beet as sucrose.
