Volgens 'n studie van die Universiteit van Texas, kan 'n hoë persentasie suikerverbruik in Westerse dieet verband hou met die risiko van kanker

Nog 'n rede om op te hou om soveel suiker te eet.

Navorsers het nog 'n rede ontdek om by te voeg tot die toenemende stapel motiverings vir minimale suikerinname. Benewens diabetes, vetsug en hartgesondheid, is suikerverbruik nou gekoppel aan 'n verhoogde risiko vir borskanker en longkanker.Navorsers van die Anderson Cancer Center, besturende direkteur van die Universiteit van Texas het bevind dat 'n suikerryke dieet meer geneig is tot die ontwikkeling van borskanker, met ontsteking van die melkklier as oorsaak.

Die studie het gekyk na die gevolge van verhoogde sukrose- en fruktoseverbruik by muise op die ontwikkeling van kankerselle, en bevind dat muise wat meer suiker verbruik, 'n risiko loop vir gewasgroei in beide die melkkliere en die longe. Die muise met 'n swaar sukrose dieet was byna twee keer meer geneig om gewasse te kweek (60 persent), as die muise op 'n styselbeheerde dieet (30 persent).

"Die huidige studie het ondersoek ingestel na die impak van suiker op die ontwikkeling van melkkliere in verskeie muismodelle, asook meganismes wat daarby betrokke kan wees," sê mede-outeur Lorenzo Cohen, Ph.D., professor in palliatiewe, rehabilitasie en integratiewe medisyne het in 'n verklaring gesê. "Ons het bepaal dat dit spesifiek fruktose was, in tafelsuiker en hoë-fruktose mieliesiroop, alomteenwoordig in ons voedselsisteem, wat verantwoordelik was vir die vergemakliking van longmetastase en die produksie van 12-HETE in borsgewasse."


Suiker in vrugtesap kan die risiko van kanker verhoog, bevind studie

Volgens 'n groot studie wat groot hoeveelhede vrugtesap gedrink het, kan u die risiko van kanker verhoog, en die verband tussen die gereelde inname van allerhande soet drankies en die waarskynlikheid om die siekte te ontwikkel, kan gevind word.

Die studie, wat in Frankryk uitgevoer is, is die eerste aansienlike stuk navorsing wat 'n spesifieke verband tussen suiker en kanker gevind het. Suikerhoudende drankies soos colas, limonade en energiedrankies is gekoppel aan vetsug, wat 'n oorsaak van kanker is, maar die Franse navorsers stel voor dat daar ook ander redes is waarom suiker dit kan veroorsaak.

Die studie, gepubliseer in die BMJ, vind dat die verband met kanker net so sterk is met vrugtesappe as met cola. "Toe die groep soet drankies verdeel is in 100% vrugtesappe en ander soet drankies, het die verbruik van albei dranksoorte 'n groter risiko vir algemene kanker in verband gebring," sê hy.

Die vermindering van die hoeveelheid soet drankies wat ons almal verbruik, tesame met suikerbelasting en bemarkingsbeperkings, kan help om die kankerlas te verminder, sê die skrywers. Dit beteken nie dat niemand hulle ooit moet drink nie. "Soos gewoonlik met voeding, is die idee nie om voedsel te vermy nie, net om die inname te balanseer," sê dr Mathilde Touvier, wat die navorsing gelei het, van Inserm, die Franse nasionale instituut vir gesondheid en mediese navorsing.

'Die aanbeveling van verskeie openbare gesondheidsagentskappe is om minder as een drankie per dag te drink. As u van tyd tot tyd 'n soet drankie inneem, is dit nie 'n probleem nie, maar as u ten minste een glas per dag drink, kan dit die risiko van verskeie siektes verhoog - hier, miskien kanker, maar ook met 'n hoë bewyse. , kardiometaboliese siektes. ”

Vrugtesappe toon dieselfde verband met kanker as colas. 'Dit lyk asof suiker die hoofbestuurder van die vereniging is, dus as ons net kyk na die suikerinhoud per 100 ml, is gewone Coke of 100% lemoensap byvoorbeeld dieselfde. Dit is dus nie so vreemd dat ons hierdie assosiasie vir vrugtesappe waarneem nie, 'het Touvier gesê.

Maar openbare gesondheidsagentskappe sê dat vrugtesappe 'n bietjie beter is omdat dit vitamiene en 'n bietjie vesel bevat, het sy bygevoeg.

Die studie is waarnemend, en daarom kan navorsers nie sê dat suiker 'n oorsaak van kanker is nie. Die skrywers vra dat dit verder ondersoek word. Hulle sê daar is aanneemlike biologiese meganismes, soos die effek van suiker op die viscerale vet wat rondom belangrike organe, soos die lewer en pankreas, bloedsuikervlakke en inflammatoriese merkers gestoor word, wat almal verband hou met 'n verhoogde risiko vir kanker.

Waarom is suiker sleg vir jou?

Deur te veel suiker te eet, dra dit daartoe by dat mense gedurende die dag te veel kalorieë inneem, wat tot gewigstoename kan lei. Oorgewig verhoog die risiko van gesondheidsprobleme soos hartsiektes, tipe 2 -diabetes en sommige vorme van kanker. Suiker is ook een van die hoofoorsake van tandbederf.

Die NHS beveel aan dat die meeste volwassenes en kinders in die Verenigde Koninkryk te veel suiker eet, genaamd 'gratis suikers'. Dit is die suikers wat by kos en drank gevoeg word, wat in koekies, sjokolade, ontbytgraan en gaskoeldrank voorkom. Maar hulle kom ook natuurlik voor in heuning en onversoete vrugtesappe.

Die aanbeveling van die Britse regering is dat hierdie 'gratis suikers' nie meer as 5% van die daaglikse kalorieë moet uitmaak nie. Dit is nog steeds baie suiker - dit is gelykstaande aan sewe suikerblokkies ter waarde van 'n volwassene. Maar hou in gedagte dat 'n blikkie gaskoeldrank die ekwivalent van 9 blokkies suiker kan bevat. Kinders jonger as 4 moet alle suiker-versoete drankies en kos vermy met 'gratis suikers' daarin.

Die data is versamel deur 'n langdurige voedingsopname in Frankryk, genaamd NutriNet-Santé, met 101.257 gesonde Franse volwassenes, waarvan 79% vroue was.

Diegene wat deelgeneem het, het ten minste twee aanlyn-gevalideerde dieetvraelyste voltooi, wat bedoel was om hul gewone inname van 3 300 voedsel- en drankartikels te meet, en is vir maksimum nege jaar opgevolg. Gedurende daardie tyd is byna 2 200 gevalle van kanker gediagnoseer, waaronder 693 borskanker. Hulle het bevind dat 'n toename van 100 ml in die verbruik van soet drankies verband hou met 'n 18% groter risiko vir algehele kanker en 'n verhoogde risiko van borskanker met 22%.

Daar was geen verband tussen kunsmatige versoeters en kanker nie, maar die getalle wat kunsmatige versoeters gebruik, was te klein om afdoende te wees.

'Dit is duidelik dat daar meer werk gedoen moet word, en die meting van die inname van die dieet is 'n uitdaging, maar die boodskap uit die hele getal bewyse oor oormaat suikerverbruik en verskillende gesondheidsuitkomste is duidelik: die vermindering van die hoeveelheid suiker in ons dieet is uiters belangrik. Dit beklemtoon waarom ons Britse suikerheffing en beheermaatreëls vir die bemarking van suikerprodukte so belangrik is, nie net wat vetsug betref nie, maar ook moontlik kankervoorkoming, ”sê dr.

Dr Graham Wheeler, 'n senior statistikus van die University College London se sentrum vir kankerproewe, het gesê die studie is groot, goed ontwerp en dra by tot die bewys van risiko. Maar, het hy gesê, “hoewel daar bewyse is vir 'n verband tussen die inname van soet drank en die risiko om borskanker te ontwikkel, is dieselfde verband nie gevind vir kolorektale of prostaatkanker nie. Verdere navorsing oor die biologiese meganisme tussen suikerhoudende drankverbruik en spesifieke kankers is nodig om vas te stel of die een die ander wel veroorsaak. ”

Hierdie artikel is op 11 Julie 2019 gewysig omdat Graham Wheeler werk vir die kankerproefsentrum van University College London, nie vir Cancer Research UK nie, soos in 'n vorige weergawe gesê is. Dit is reggestel.

Oorgewig verhoog die risiko van gesondheidsprobleme soos hartsiektes, tipe 2 -diabetes en sommige vorme van kanker. Suiker is ook een van die hoofoorsake van tandbederf.

Die NHS beveel aan dat die meeste volwassenes en kinders in die Verenigde Koninkryk te veel suiker eet, genaamd 'gratis suikers'. Dit is die suikers wat by kos en drank gevoeg word, wat in koekies, sjokolade, ontbytgraan en gaskoeldrank voorkom. Maar hulle kom ook natuurlik voor in heuning en onversoete vrugtesappe.

Die aanbeveling van die Britse regering is dat hierdie 'gratis suikers' nie meer as 5% van die daaglikse kalorieë moet uitmaak nie. Dit is nog steeds baie suiker - dit is gelykstaande aan sewe suikerblokkies ter waarde van 'n volwassene. Maar hou in gedagte dat 'n blikkie gaskoeldrank die ekwivalent van 9 blokkies suiker kan bevat. Kinders jonger as 4 moet alle suiker-versoete drankies en kos vermy met die byvoeging van 'gratis suikers'.

Die data is versamel deur 'n langdurige voedingsopname in Frankryk, genaamd NutriNet-Santé, met 101.257 gesonde Franse volwassenes, waarvan 79% vroue was.

Diegene wat deelgeneem het, het ten minste twee aanlyn-gevalideerde dieetvraelyste voltooi, wat bedoel was om hul gewone inname van 3300 voedsel- en drankartikels te meet, en is vir maksimum nege jaar opgevolg. Gedurende daardie tyd is byna 2 200 gevalle van kanker gediagnoseer, waaronder 693 borskanker. Hulle het bevind dat 'n toename van 100 ml in die verbruik van soet drankies verband hou met 'n verhoogde risiko van algehele kanker met 18% en 'n verhoogde risiko van borskanker met 22%.

Daar was geen verband tussen kunsmatige versoeters en kanker nie, maar die getalle wat kunsmatige versoeters gebruik het, was te klein om afdoende te wees.

'Dit is duidelik dat daar meer werk gedoen moet word, en die meting van die inname van die dieet is 'n uitdaging, maar die boodskap uit die hele getal bewyse oor oormaat suikerverbruik en verskillende gesondheidsuitkomste is duidelik: die vermindering van die hoeveelheid suiker in ons dieet is uiters belangrik. Dit beklemtoon waarom ons Britse suikerheffing en beheermaatreëls vir die bemarking van suikerprodukte so belangrik is, nie net wat vetsug betref nie, maar ook moontlik kankervoorkoming, ”sê dr.

Dr Graham Wheeler, 'n senior statistikus van die University College London se sentrum vir kankerproewe, het gesê die studie is groot, goed ontwerp en dra by tot die bewys van risiko. Maar, het hy gesê, “hoewel daar bewyse is vir 'n verband tussen die inname van soet drank en die risiko om borskanker te ontwikkel, is dieselfde verband nie gevind vir kolorektale of prostaatkanker nie. Verdere navorsing oor die biologiese meganisme tussen suikerhoudende drankverbruik en spesifieke kankers is nodig om vas te stel of die een die ander wel veroorsaak. ”

Suiker in vrugtesap kan die risiko van kanker verhoog, bevind studie

Volgens 'n groot studie wat groot hoeveelhede vrugtesap gedrink het, kan u die risiko van kanker verhoog, en die verband tussen die gereelde inname van allerhande soet drankies en die waarskynlikheid om die siekte te ontwikkel, kan gevind word.

Die studie, wat in Frankryk uitgevoer is, is die eerste aansienlike stuk navorsing wat 'n spesifieke verband tussen suiker en kanker gevind het. Suikerhoudende drankies soos colas, limonade en energiedrankies is gekoppel aan vetsug, wat 'n oorsaak van kanker is, maar die Franse navorsers stel voor dat daar ook ander redes is waarom suiker dit kan veroorsaak.

The study, published in the BMJ, finds the association with cancer is just as strong with fruit juices as it is with colas. “When the group of sugary drinks was split into 100% fruit juices and other sugary drinks, the consumption of both beverage types was associated with a higher risk of overall cancer,” it says.

Cutting down on the amount of sugary drinks we all consume, together with sugar taxes and restrictions on marketing, might help reduce the cancer burden, say the authors. That does not mean nobody should ever drink them. “As usual with nutrition, the idea is not to avoid foods, just to balance the intake,” said Dr Mathilde Touvier, who led the research, from Inserm, the French national institute of health and medical research.

“The recommendation from several public health agencies is to consume less than one drink per day. If you consume from time to time a sugary drink it won’t be a problem, but if you drink at least one glass a day it can raise the risk of several diseases – here, maybe cancer, but also with a high level of evidence, cardiometabolic diseases.”

Fruit juices showed the same association with cancer as colas. “The main driver of the association seems to be sugar, so when we just look at the sugar content per 100ml, regular Coke or 100% orange juice, for instance, are quite the same. So it’s not so odd that we observe this association for fruit juices,” said Touvier.

But public health agencies say that fruit juices are a little bit better because they contain some vitamins and a little bit of fibre, she added.

The study is observational, so it is not possible for the researchers to state that sugar is a cause of cancer. The authors call for that to be investigated further. They say there are plausible biological mechanisms, such as the effect of sugar on the visceral fat stored around vital organs such as the liver and pancreas, blood sugar levels and inflammatory markers, all of which are linked to increased cancer risk.

Eating too much sugar contributes to people having too many calories during the day, which can lead to weight gain. Being overweight increases the risk of health problems such as heart diseases, type 2 diabetes, and some forms of cancer. Sugar is also one of the main causes of tooth decay.

The NHS advises that most adults and children in the UK eat too much of a type of sugar called 'free sugars'. These are the sugars added to food and drinks, found in biscuits, chocolate, breakfast cereals and fizzy drinks. But they are also found naturally in honey and unsweetened fruit juices.

The UK government’s recommendation is that these 'free sugars' should not make up more than 5% of the calories you have every day. That is still quite a lot of sugar - it equates to seven sugar cubes worth for an adult. But bear in mind that one can of a fizzy drink can include the equivalent of 9 cubes of sugar. Children under 4 should avoid all sugar-sweetened drinks and food with added 'free sugars' in it.

The data was collected through a long-running nutrition survey in France, called NutriNet-Santé, involving 101,257 healthy French adults, 79% of whom were women.

Those taking part had completed at least two 24-hour online validated dietary questionnaires, designed to measure their usual intake of 3,300 food and beverage items, and were followed up for a maximum of nine years. Over that time, nearly 2,200 cases of cancer were diagnosed, including 693 breast cancers. They found that a 100ml increase in sugary drink consumption was associated with an 18% increased risk of overall cancer and a 22% increased risk of breast cancer.

There was no link between artificial sweeteners and cancer, but the numbers using artificial sweeteners were too small to be conclusive.

“Clearly there is more work to be done and measuring dietary intake is challenging – however, the message from the totality of evidence on excess sugar consumption and various health outcomes is clear – reducing the amount of sugar in our diet is extremely important. This highlights why our UK sugar levy and controls on the marketing of high-sugar products is so important, not only in terms of obesity but also possibly cancer prevention,” said Dr Amelia Lake, reader in public health nutrition at Teesside University.

Dr Graham Wheeler, a senior statistician at University College London’s cancer trials centre, said the study was large, well designed and added to the evidence of risk. But, he said, “whilst there was some evidence for an association between sugary drink consumption and the risk of developing breast cancer, the same association was not found for colorectal or prostate cancers. Further research into the biological mechanism between sugary drink consumption and specific cancers is needed to establish if one does indeed cause the other.”

Sugar in fruit juice may raise risk of cancer, study finds

Drinking large amounts of fruit juice may raise your risk of cancer, according to a big study which has found a link between the regular consumption of all kinds of sugary drinks and the likelihood of developing the disease.

The study, carried out in France, is the first substantial piece of research to find a specific association between sugar and cancer. Sugary drinks such as colas, lemonade and energy drinks have been linked to obesity, which is a cause of cancer, but the French researchers suggest there could also be other reasons sugar could trigger it.

The study, published in the BMJ, finds the association with cancer is just as strong with fruit juices as it is with colas. “When the group of sugary drinks was split into 100% fruit juices and other sugary drinks, the consumption of both beverage types was associated with a higher risk of overall cancer,” it says.
