[Fructose consumption and its health implications; fructose malabsorption and nonalcoholic fatty liver disease].

UNLABELLED: Fructose intake has increased considerably in recent years, especially in the form high fructose corn syrup, due its high sweetening power. Several studies have associated high intake of fructose to metabolic alterations, as nonalcoholic fatty liver disease and fructose malabsorption, among other pathologies. This review aims to update about the effect of high intake of fructose in the liver and intestine, mainly associated with processed foods with added fructose.

METHODS

An updated literature search was conducted using databases (Pubmed, Scopus and SciELO), selecting articles published after the year 2000, resulting from the keywords "fructose intake, fructose intolerance, nonalcoholic fatty liver and fructose, fructose malabsorption"

RESULTS

Of 735 articles initially retrieved, 78 met the inclusion criteria.

CONCLUSIONS

Fructose consumption has increased in recent decades, especially due to increased consumption of sweetened beverages and processed foods with added fructose. High fructose intake has been associated to pathologies as NAFLD and fructose malabsorption.
