Fructose consumption shown to damage liver by altering energy balance

by John Phillip 

(NaturalNews) Mortality from diseases of the liver has increased over the past half-century to secure a place as one of the top, leading causes of death each year in the United States. One hundred years ago, liver disease was virtually unheard of except for the occasional death from alcoholic cirrhosis. Today, non-alcoholic fatty liver disease (NAFLD) is a common diagnosis caused by an inability to effectively clear fat stores from the organ. Metabolic function quickly becomes compromised and liver failure can be a potentially fatal result.

The skyrocketing rise in the number of overweight and obese individuals is a significant contributing factor to the epidemic of deaths recorded from liver disease. Prior research bodies have implicated increased use of fructose, and its super-charged twin, high fructose corn syrup with weight gain and NAFLD. Fructose consumption in the U.S. has more than doubled in the past 30 years and is found in fruits and vegetables, whereas HFCS is a mixture of glucose and fructose that is used as a sweetener in many processed consumer food products including bread, cereal, and soda.

Researchers publishing in the journal of the American Association for the Study of Liver Diseases, Hepatology, found that obese patients with type 2 diabetes who consume higher amounts of fructose, display reduced levels of liver adenosine triphosphate (ATP), a compound involved in energy transfer between cells. The scientists determined that elevated uric acid levels are associated with more severe hepatic ATP depletion as fructose consumption is increased.

Excess fructose consumption can compromise liver function leading to organ failure

To conduct the study, researchers evaluated 244 obese and diabetic adults from the Look AHEAD Study, with dietary fructose consumption estimated by a food frequency questionnaire. The scientists assessed changes in liver ATP content using an IV-delivered fructose challenge, and then compared patients with low fructose consumption (fewer than 15 grams per day) to those with high fructose consumption (greater than 15 grams per day).

The researchers determined that participants with the highest intake of dietary fructose had lower liver ATP levels and a greater change in ATP content following the fructose challenge as compared to those who consumed a lower amount of fructose. Patients with high uric acid levels displayed lower ATP stores in response to fructose. This means that fructose consumption is directly correlated to metabolic liver function and is a significant determinant in how well the liver performs its more than 300 critical functions necessary to sustain life.

The study team concluded “High fructose consumption and elevated levels of uric acid are associated with more severe depletion of liver ATP. Our findings suggest that increased dietary fructose intake may impair liver ‘energy balance.'” This study reinforces the wealth of scientifically validated research to avoid excess fructose consumption from sweetened beverages and processed foods to avoid weight gain and risk of NAFLD and liver failure.

Cancer du pancréas: le fructose alimenterait les cellules cancéreuses

Cancer du pancréas: le fructose alimenterait les cellules cancéreuses
17 août 2010 – Le fructose raffiné, qu’on retrouve dans une multitude de produits alimentaires transformés, contribuerait à la croissance des cellules responsables du cancer du pancréas.
C’est ce que soutiennent des chercheurs1 qui ont exposé des tumeurs pancréatiques, prélevées sur des patients, à du glucose ou du fructose.
Comme d’autres études l’ont démontré, le glucose – ou sucre raffiné – a facilité la croissance des cellules cancéreuses. Toutefois, le fructose raffiné a eu un effet semblable.
Bien que l’expérience ait été menée sur des cellules de cancer du pancréas, les chercheurs soulignent que l’effet procancer du fructose pourrait s’appliquer à d’autres types de cancers.
De même, les concentrations de fructose auxquelles les cellules cancéreuses ont été exposées en laboratoire correspondent à des concentrations comparables à celles que l’on retrouve actuellement dans l’alimentation humaine, selon les chercheurs.
Précisons que la consommation de fructose a considérablement augmenté au cours des 40 dernières années, principalement depuis l’apparition, au début des années 1970, du sirop de maïs hydrolysé riche en fructose.
Cet édulcorant a remplacé le glucose dans une foule d’aliments préparés, en raison de son faible coût et de son important pouvoir sucrant. On estime que la consommation de fructose chez les humains a été multipliée par 1 000 entre 1970 et 1990.
On retrouve le sirop de maïs hydrolysé riche en fructose dans les pâtisseries, les boissons sucrées, les friandises, les gâteaux et les biscuits, les repas congelés, le ketchup, les vinaigrettes commerciales, les barres de céréales ainsi que dans une foule d’autres aliments transformés.
