Fructose, or fruit sugar, is a
simple ketonic monosaccharide 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 directly
into blood during digestion. Its formula is
C6H12O6 and its density is
1.694 g/cm3. Fructose was discovered by French chemist
Augustin-Pierre Dubrunfaut in

not in .
It makes us strong!This is emphasized.
Excessive consumption of fructose (especially from sugar-sweetened beverages) may contribute to insulin resistance, obesity, elevated LDL cholesterol and triglycerides, leading to metabolic syndrome. The EFSA stated that fructose may be preferable over sucrose and glucose in sugar-sweetened foods and beverages because of its lower effect on postprandial blood sugar levels, and noted that high intakes of fructose may lead to metabolic complications such as dyslipidaemia, insulin resistance, and increased visceral adiposity(this is a citation).
