Fructose is a naturally occurring sugar primarily found in fruits. You can also find it in plants, honey, vegetables, and sugar cane. It is a monosaccharide, otherwise known as a simple carbohydrate, like sucrose or glucose. You may find fructose in a few different forms, like crystalline, powder, or in a liquid syrup like agave or high fructose corn syrup. Consuming whole fruits will provide an abundance of nutrients and help control energy intake. It takes over 8 pounds of most fresh fruit to provide 2000 calories. Humans usually don’t eat more than ~5 pounds of food per day. HFCS can also harm your liver. In fact, it may be a leading cause of non-alcoholic fatty liver disease (NAFLD), which affects around 80 to 100 million people ( x).

Ultimately, fructose is really no better or worse than any other sugar. Nutritionally, fructose is nearly identical to sucrose, both containing approximately four calories per gram. When used in moderation, any undesirable health hazards can be avoided. Fructose is also derived from the digestion of sucrose, a disaccharide consisting of glucose and fructose that is broken down by enzymes during digestion. Fructose is often recommended for, and consumed by, people with diabetes mellitus or hypoglycemia, because it has a very low Glycemic Index (GI 23) relative to cane sugar (sucrose). However, this benefit is tempered by concern that fructose may have an adverse effect on plasma lipids. The low GI is due to the unique and lengthy metabolic pathway of fructose, which involves phosphorylation and a multi-step enzymatic process in the liver. The results of some studies have confirmed this finding, although others have stated there is no correlation. FOS is broken down in various ways, and this results in different end products that have different uses and varying benefits. FOS comes in a few different forms, and each may be used for a specific purpose. Syrups Skoog, SM; Bharucha AE (2004). "Dietary fructose and gastrointestinal symptoms: a review". Am. J.

Fruits and vegetables contain the only amounts of natural fructose, and even they provide meager amounts of it.

Fructose may be anaerobically fermented by yeast and bacteria. [19] Yeast enzymes convert sugar ( sucrose, glucose, and fructose, but not lactose) to ethanol and carbon dioxide. [20] Some of the carbon dioxide produced during fermentation will remain dissolved in water, where it will reach equilibrium with carbonic acid. The dissolved carbon dioxide and carbonic acid produce the carbonation in some fermented beverages, such as champagne. Fructose ( / ˈ f r ʌ k t oʊ s, - oʊ z/), or fruit sugar, is a ketonic simple sugar found in many plants, where it is often bonded to glucose to form the disaccharide sucrose. It is one of the three dietary monosaccharides, along with glucose and galactose, that are absorbed by the gut directly into the blood of the portal vein during digestion. The liver then converts both fructose and galactose into glucose, so that dissolved glucose, known as blood sugar, is the only monosaccharide present in circulating blood.

Increased concentrations of DHAP and glyceraldehyde 3-phosphate in the liver drive the gluconeogenic pathway toward glucose and subsequent glycogen synthesis. [54] It appears that fructose is a better substrate for glycogen synthesis than glucose and that glycogen replenishment takes precedence over triglyceride formation. [55] Once liver glycogen is replenished, the intermediates of fructose metabolism are primarily directed toward triglyceride synthesis.
