The average American consumes their body weight annually in this cancer-causing substance,and yet hospitals freely feed it to their cancer patients,oblivious to the harm it does.


Hospitals feed cancer patients sugar and high carbohydrate diets for a reason:they are abysmally ignorant of the role of nutrition in health and disease--hence their burgeoning growth and packed rooms.


Even though the science itself shows–at least since the mid-20's with Otto Warburg's cancer hypothesis--that tumors prefer to utilize sugar fermentation to produce energy rather than the much more efficient oxygen-based phosphorylation*–hospitals have actually invited corporations like McDonald's to move into their facilities to'enhance'their patient's gustatory experience,presumably to provide comfort and take the edge off of the painful surgery,radiation and chemo treatments erroneously proffered to them as the only reasonable'standard of care.'


But the times are changing,with new research requiring these medical institutions to reform their dietary strategies,at least if they wish to claim that their interventions are in fact'evidence-based'...


New Study Reveals Sugar Doesn't Just Feed But Causes Cancer


A groundbreaking new study,uncovered by one of our volunteer researchers at Greenmedinfo–Jonathan Middleton–is the first of its kind to identify sugar,not only as fuel source for an already existing cancer,but as a primary driver in oncogenesis–i.e.the initiation of cancerous characteristics(phenotype)within previously healthy cells.

我们在 Greenmedinfo 的一位志愿者研究人员乔纳森米德尔顿发现了一项开创性的新研究,该研究首次发现糖不仅是已经存在的癌症的燃料来源,而且是肿瘤发生的主要驱动因素——即在以前健康的细胞中发生癌症特征(表型)

Published in the Journal of Clinical Investigation and titled,Increased sugar uptake promotes oncogenesis via EPAC/RAP1 and O-GlcNAc pathways,researchers addressed a common perception(or misperception)in the cancer research community regarding sugar's relationship to cancer:namely,"increased glycolysis[sugar based metabolism]is frequently viewed as a consequence of oncogenic events that drive malignant cell growth and survival."

研究人员在《临床研究杂志》上发表了一篇题为《增加糖摄取通过 epac/rap1 O-GlcNAc 通路促进肿瘤形成》的文章,他们解决了癌症研究界对于糖与癌症关系的一个普遍看法(或误解):"增加糖酵解[以糖为基础的新陈代谢]通常被认为是促进恶性细胞生长和存活的致癌事件的结果。"

Contrary to this conventional view,the new study"provide展开evidence that increased glycolytic activation itself can be an oncogenic event..."That is to say,the activation of sugar-based metabolism in a cell–driven by both the presence of increased quantities of glucose and the increase glucose receptors on the cell membrane surface(i.e."overexpression of a glucose transporter")–drives cancer initiation.


Moreover,the study found that"Conversely,forced reduction of glucose uptake by breast cancer cells led to phenotypic reversion."In other words,interfering with sugar availability and uptake to the cell causes the cancer cell to REVERSE towards its pre-cancer structure-function(phenotype).


What Are The Implications of This Research to the Diet?


What this new research indicates is that sugar–of which Americans consume an astounding 160 lbs annually(imagine:31 five-pound bags for each of us!)–is one of the primary causes of metabolic cell changes in the body consistent with the initiation and promotion of cancer.And,the research indicates that removing it from the diet,and depriving the cells of it,could REVERSE cancer.


Hidden Sugar,Crouching Cancer


It has beenestimated by the USDA that the average American consumes 200 lbs of grain products annually.Why is this relevant to the question of sugar in the diet?Because refined carbohydrate products–e.g.crackers,bread,pasta,cereal–are actually'hidden'forms of sugar.In fact,puffed rice causes your blood to become sweeter(and presumably feeds more cancer cells sugar)than white sugar,as it is higher on the glycemic index.Adding the two figures together–annual per capita consumption of sugar and grain-based products–we get a jaw dropping 360 lbs of sugar(both overt(table sugar/high fructose corn syrup)and covert(grain carbs)annually–all of which may contribute to promoting the ideal metabolic situation of cancer cells:aerobic glycolysis.


This is one reason why the ketogenic diet–that is,a fat-and protein-focused diet devoid of carbohydrate,both in simple(sugar)and complex(grain product)form–has been found so useful in the most aggressive of cancers:including brain cancer.Once you'pull the rug out'from under the sugar/carb-craving cancer cells,they are forced to either undergo programmed cell death(apoptosis)or re-differentiate back into non-cancerous phenotypes.


If It's So Bad For Us,Why Do We Eat So Much?


One of the primary reasons why we eat sugar and carbohydrate rich diets is because they are addictive.Within minutes of consuming sugar/carbs our body goes through a neuroendocrine roller coaster.Your brain can not survive very long without glucose,the fundamental energy unit of the cell,and will'freak out'if deprived of a steady stream of this'nutrient'within only 2-3 minutes.The endocrine system,on the other hand,perceives the danger of high sugar–namely,glycation associated damage to protein and lipid structures within the cells of our body;think:blood caramelizing,getting sticky,and gumming up the finely tuned works–and will release hormones such as insulin,adrenaline and cortisol,in order to try to get the elevated sugar in the blood and tissues under control.Insulin forces the sugar into storage within the cell,both as glycogen and as fat,but often does its job too well,causing available glucose levels in the brain to be depleted–setting off a vicious cycle of'emergency signals'telling the body to release more cortisol and adrenaline to increase the levels of glucose in the blood.This,of course,will result in additional insulin production and release,causing the same cycle to be repeated over and over again.


This seemingly endless vicious cycle is responsible for the insatiable cravings a high carb/sugar diet generates–not to mention the fructose-based hedonic effects generated in the brain  that modulate both opioid and dopamine receptors in the nervous system(not unlike alcohol),and the pharmacologically active peptides in many gluten-containing grains,which also drive addictive behaviors and an almost psychotic fixation on getting carbs at each meal.


No wonder we have an epidemic of cancer in a world where the Westernized diet prevails.Certainly,we do not mean to indicate that a sugar/carb-rich diet is the only cause of cancer.There are many other factors that contribute to cancer initiation and promotion,such as:


  • Chemical exposure
  • 化学物摄入量
  • Radiation exposure
  • 辐射暴露
  • Chronic stress that suppresses the immune system
  • 抑制免疫系统的慢性压力
  • Vaccines containing hidden retroviruses and cancer causing viruses
  • 含有隐藏的逆转录病毒和致癌病毒的疫苗
  • Natural infection with bacteria and viruses that are cancer causing
  • 自然感染引起癌症的细菌和病毒
  • Lack of sleep
  • 睡眠不足
  • Insufficient nutrients(lack of methyl donors such as B12,folate,and B6 will prevent the body from'turning off'(methylating)cancer-promoting genes
  • 营养不足(缺乏甲基供体,如 B12、叶酸和 B6,将阻止身体"关闭"(甲基化)促癌基因

Even though cancer is a complex,multi-factorial phenomena,with variables we can not always control,one thing we can do is control what goes into our mouth.Sugar,for instance,does not belong there if we truly want to prevent and/or treat cancer.And don't forget,carbohydrates that don't taste sweet on the front end–bread,crackers,cereal–certainly convert to sugar in the body within minutes post-consumption.


In a nutshell,if you are concerned about cancer,have cancer,or would like to prevent recurrence,removing sugar and excess carbohydrates is a must.Not only is it common sense,but it is now validated by experimental research.
