A recent study did a similar analysis using questionnaire-based data from 477,199 participants included in the European Prospective Investigation into Cancer and Nutrition cohort study, most of which were women with a mean age of 51 years. During a follow up of 11.6 years, 865 pancreatic cancers were reported.

Unlike the previous study, this study found that total sweet beverage consumption may not be associated with pancreatic cancer risk. The study also found that juice and nectar consumption might be associated with a slight decrease in pancreatic cancer risk. Pancreatic cancer patients may have to avoid very high intake of drinks with concentrated sugar.

How To Spot Hidden Sugars

If you check food labels then you may want to look for these sugars: :

â fructose â sucrose â maltose â glucose â dextrose Any sugar listed as one of the top ingredients would be of concern when looking at sugar content. This applies to people with and without cancer who are trying to stay away from sugars and maintain a healthy weight.

The Connection Between Weight Gain And Cancer

While there is no evidence to directly link sugar consumption and cancer growth, you should still be mindful of how much sugar you eat or drink.

Added sugar has no nutritional value. The empty calories are stored as fat and cause weight gain.

Research has found those who are overweight or obese, have an increased risk of cancer including pancreatic, breast, liver and kidney cancer. Obesity also increases your risks of developing other chronic illnesses that could make cancer treatment more difficult.

According to the 2015-2020 Dietary Guidelines for Americans, added sugar should amount to no more than 10 percent of your daily calories. For someone on a 2,000-calorie diet, this would mean less than 12 teaspoons of sugar a day.

How Can I Cut Down On Free Sugar

Its free sugar were mainly concerned with when it comes to weight gain, not sugar that is naturally found in foods like fruits and milk or healthy starchy foods like wholegrains and pulses .

One of the easiest ways to lower your added sugar is to cut down on sugary drinks, which are the largest source of sugar in the UK diet.

Some sugary drinks, such as fizzy drinks and energy drinks, can have more than the recommended daily maximum amount of free sugar in one serving alone. And while these extra calories promote weight gain, they offer no other nutritional benefits.

Other obviously sugary foods such as sweets, chocolate, cakes and biscuits are all best kept as treats too. But some foods that have hidden high amounts of added sugar may surprise you. Some breakfast cereals, ready meals , pasta sauces and yoghurts can have shocking amounts of sugar added to them. Reading nutrition information labels and checking the ingredients list can help you choose lower sugar options.

While there are steps you and your family can take to cut down on added sugar, making these changes can be easier said than done. And its here that governments need to lend a hand.

Carbohydrates Raise Insulin Levels Could Abnormal Levels Of Insulin Lead To Cancer

Subversion of Systemic Glucose Metabolism as a Mechanism to Support the ...

Insulins job is to tell the cells in our body, Hey! Theres a lot of glucose. We should use it. Therefore, if we could get people to produce less insulin, they might do better. But the real root problem of the worldwide obesity epidemic and cancer as a result of obesity has to do with too much caloric intake. It has little to do with abnormal insulin signaling.

Although Sugar Does Not Feed Cancer It Is Still A Good Idea To Limit Sugar In Your Diet As It Provides Very Little Nutritional Value

The following are some tips for making sure you are eating a nutritious diet:

Choose complex carbohydrates instead of sweets and sugar sweetened drinks.

  • The body needs nutritious food during cancer treatment. Choose foods that provide the body with nutrients, not only sugar.
  • Examples of complex carbohydrates include fruits and vegetables and whole-grain breads, cereals, rice, and pastas. Beans such as kidney, pinto, and black beans are all excellent sources of protein and complex carbohydrates.

Eat consistently and regularly to keep blood sugar level stable.

  • Eat small meals every 2-3 hours including a source of lean protein, complex carbohydrate, and healthy fat.
  • Here are some examples of healthy mini meals:
  • ½ of a sandwich made from a slice of 100% whole-wheat bread, 2 tsp. peanut butter, 1 tsp. fruit preserves
  • 1/2c. cottage cheese and ½ c. canned fruit in 100% juice
  • 1/4c. black beans, 1/2c. brown rice, 1 Tbsp. salsa

Beware of becoming obsessed with food, ingredient lists, etc. Try to relax and set realistic food goals.

Sugar Insulin And Breast Cancer

Some doctors take a different approach. âI tell people that they should reduce sugar consumption and carbohydrate consumption,â says Victoria Seewaldt, MD, chair of the Department of Population Sciences at City of Hope, a cancer research and treatment center near Los Angeles.

Seewaldt, who studies cancer prevention, has long been interested in the link between breast cancer and the hormone insulin. Your pancreas makes insulin to help your body store glucose broken down from carbohydrates in cells in muscle, fat, and other tissues. Eating a lot of sugar and other carbohydrates raises blood sugar levels and insulin production.

Breast cancer is a complex disease involving a number of factors, Seewaldt says, including insulin. She explains that insulin helps stimulate a number of biological changes in the body that are known to promote breast cancer. âInsulin is a really bad actor,â Seewaldt says.

Reprogramming metabolism is an emerging hallmark of cancer cells, with glycolysis as the main pathway of energy production, even when sufficient oxygen is present, a phenomenon referred to as the Warburg effect. Owing to this metabolic adaptation, cancer cells consume large quantities of glucose to survive through hypoxic conditions, commonly found in tumors, and support their anabolic requirements for uncontrolled growth and division. Therefore, dietary restriction of carbohydrates and pharmacologic agents that decrease insulin production or inhibit insulin signals have been exploited as potential therapeutic methods for cancer prevention or treatment. On the other hand, how carbohydrate intake may influence the incidence of cancer in the general population remains unclear.

Case Study: Charless Story

Cancer Lives on Sugar AND…Something Else!!

One UK patient lets call him Charles developed a vascular highly malignant brain tumour, known as an anaplastic astrocytoma, in 2013. The chemotherapy left him feeling terrible, so he decided to abandon it and turned to the high fat diet instead. Young, fit and a personal trainer with a degree in sports nutrition, he felt it was worth the risk, although his oncologist warned him that the diet would have no effect on the tumour, and cutting out carbs would be dangerous because his brain needed glucose to function. Charles ignored the advice and began the standard ketogenic combination of reducing his intake of carbs and replacing the lost calories with low sugar fruits and vegetables, coconut milk and oil, nuts, cheese, avocados and so on. Unfortunately, this diet left him feeling absolutely awful: his migraines and seizures common side effects of brain cancer grew so bad that he remained in bed for months.

Thereafter, Charles continued to tinker with his diet until he achieved the best possible balance for his personal needs. At first, he relied on bone broth and organ meats , which kept his headaches and seizures at bay while his brain scans continued to show improvement. Then he took another leap: I added insects to my diet, along with some MCT oil, which the liver can turn directly into ketones.

Many people would find it impossible to follow such a diet: it comprises over 200g of fat and 7075g of protein each day.

Sugar And The Microbiome: Project 259

Back in the 1960s, the debate was all about heart disease. Who is the culprit: sugar or fat?

A 1967 review article in The New England Journal of Medicine concluded that dietary fats were to blame. What wasnt clear at the time, though, was that the authors received funding from the SRF equivalent to roughly $50,000 in todays money to publish their review.

Disclosure of conflict of interest wasnt mandatory until the 1980s, so technically, this wasnt wrong. But what it did do was set the scene for more clandestine research to follow.

The review revealed that rats fed a high-sucrose diet had higher serum cholesterol levels than those on a starch-based diet. The authors speculated that gut bacteria were to blame.

And so Project 259 was born in 1968. This was a study to compare the nutritional effects of organisms in the intestinal tract in rats fed sucrose versus those fed starch.

A substantial funding grant the equivalent of $187,583 in todays money went to W.F.R. Pover, from the Department of Clinical Biochemistry at the University of Birmingham in the United Kingdom, to get to the bottom of this phenomenon.

Stanton A. Glantz is the senior author of the paper published in the journal PLOS Biology and a professor at the University of California, San Francisco.

So, there was a difference. But what does this have to do with cancer?

May Increase Your Risk Of Cancer

Eating excessive amounts of sugar may increase your risk of developing certain cancers.

First, a diet rich in sugary foods and beverages can lead to obesity, which significantly raises your risk of cancer .

Furthermore, diets high in sugar increase inflammation in your body and may cause insulin resistance, both of which increase cancer risk .

A study in over 430,000 people found that added sugar consumption was positively associated with an increased risk of esophageal cancer, pleural cancer and cancer of the small intestine .

Another study showed that women who consumed sweet buns and cookies more than three times per week were 1.42 times more likely to develop endometrial cancer than women who consumed these foods less than 0.5 times per week .

Research on the link between added sugar intake and cancer is ongoing, and more studies are needed to fully understand this complex relationship.


Too much sugar can lead to obesity, insulin resistance and inflammation, all of which are risk factors for cancer.

Explain Why Its Hard To Starve Cancer Of Sugar Just By Changing Your Diet

Because your body has this interesting fail-safe system that never lets your blood glucose level drift below a certain number. So eating less sugar will just make the body use its remaining resources to produce the glucose on its own.

Everything about your biology has been naturally selected for at least 600 million years to make sure that no matter what you eat, you keep enough glucose in your system and dont become deficient. So its very hard to affect the system by changing your diet.

Understanding The Answer To Does Sugar Feed Cancer


Hopefully, now you have a little more clarity about how sugar impacts the body of individuals dealing with cancer. While there is no direct link to sugar consumption and an increase in risk exposure to cancer or cancer growth, you should still monitor your intake and keep it to a minimum.

Not All Sugars Are Created Equal

While most fruits do have a high sugar content, they are also rich in nutrients that are known to be cancer protective. Milk is another food that sometimes gets excluded due to its sugar content, but it too, is rich in important nutrients such as protein, which is in high demand during cancer treatment, and calcium. These nutrition powerhouses should not be grouped with other high sugar foods such as candy, cookies, and cakes. These sugar rich foods are high in sugar but low in healthy nutrients and should be eaten sparingly.

Guess What Else Causes Cancer Cells To Grow Stress

The stress response triggers the release of hormones such as cortisol that raise blood sugar and weaken the immune system. So putting yourself on a strict low carb diet could not only make you socially withdrawn and grumpy, but also stress you out at a time when you dont need more pressure.

This doesnt mean you should stock up on sugary cereals, pastries and cake . Eating excess sugar from these fast carbs means youre getting plenty of empty calories that can cause weight gain. Being overweight ups your risk of several types of cancer. If youre a cancer survivor, it could also increase the risk of the cancer coming back or of you developing another type of cancer . Not to mention type 2 diabetes and heart disease, but I digress!

Cancer And Sugar: Is There A Link

You might have heard that sugar causes cancer or makes it grow faster. In some ways, this makes sense. Every cell in your body uses blood sugar for energy. But cancer cells use about 200 times more than normal cells. Tumors that start in the thin, flat cells in your lungs gobble up even more glucose. They need huge amounts of sugar to fuel their growth.

The sugar your cells need comes from your diet. And not just from gooey desserts or giant white chocolate mochas. Sugar is also found in:

  • Carbs like bread, pasta, and rice

What would happen if you cut out these foods? Would that slow cancer or stop it from forming in the first place?

So far, thereâs not much proof that a low-sugar or low-carb diet lowers your chance of cancer. One exception is cancer of the esophagus, the tube that runs from your throat to your stomach. A recent study suggests that sugar and sweetened drinks may raise the chances of this cancer by 70% or more.

Why Is Sugar Bad For You

Does Sugar Increase Cancer Risk?

Foods high in added sugars tend to be heavily processed and low in nutrients, and they may also be high in unhealthy fats. These foods offer little nutritional value to your body and may fill you up and take the place of nutrient-dense foods in your diet.

Excess sugar may lead to unhealthy weight gain, forming fat around the midsection, and high blood-sugar levels, which may cause insulin resistance. Research shows that limiting your intake of added sugars reduces your risk of becoming overweight or obese or developing tooth decay. Excessive sugar consumption has been linked to a higher risk of chronic diseases and conditionsin part by increasing the risk for metabolic syndromeincluding:

Heart disease: The risk of heart disease increases among those who get more than 25 percent of their daily caloric intake from added sugars.

Type 2 diabetes: The risk of diabetes may be reduced by limiting the added sugar intake to 5 percent of total daily calories, which improves glucose tolerance and decreases the prevalence of diabetes and related metabolic abnormalities.

Non-alcoholic fatty liver disease : Large amounts of added sugars such as fructose may create a buildup of fat in the liver, which may increase the risk of this disease. Carrying extra weight and being inactive also may increase risk. Reducing sugar intake may be of benefit for NAFLD.

More On Sugar And Cancer

I have received many comments in response to my article 5 Reasons Cancer and Sugar are Best Friends. Two responses in particular challenged what I wrote. Cyndy questioned,

Numerous medical entities state sugar does not speed up the growth of cancer, nor does cancer recede or slow down if sugar is removed from the diet. So, can you please explain why you are stating the opposite to their research?

And Jan asked,

Why do you disagree with the American Cancer Society, Mayo Clinic, John Hopkins, and numerous oncologists on whether sugar feed cancer? They all say no but you are saying it does. Please let me know why you take this position.

Well, here is my detailed response to these questions and some of the latest research that validates what I have been saying about sugar and cancer.
