Humans need sugar, but not too much!

Sugar is sweet, full of calories, and a very simple form of a carbohydrate that is quite easily digested and used efficiently by the body for it’s important metabolic needs.  Too much, however, is unnecessary.  Yet in todays world, getting too much is becoming too easy. 

Sugar is hidden within numerous packaged food products to promote shelf life and increase the bliss felt after eating something so sweet.  Sugar is delicious.  From an evolutionary perspective, we have an innate taste for sugar, that proves full of pleasure.  At times of famine, this calorie rich nutrient was essential for survival, and due to our biological makeup, we still feel this need.  Sugar causes the chemical called dopamine to be released in the brain and can be addictive. 

Maintaining normal blood sugar levels is critical for muscular energy and to sustain a healthy brain.  If you are active, having a good supply of stored energy, called glycogen, is important for the muscles to tap into.  Sugar makes up this energy supply within our skeletal muscles and liver.  When it’s depleted, our bodies will find alternate pathways to create sugar through the breakdown of our own fats and proteins in our muscles.  To prevent this, eating carbs are necessary.


Simple or Complex?

Carbohydrates come in two “flavors”: simple and complex.

Simple carbohydrates are found in foods like white rice, cookies, and candies. They tend to have a sweeter taste and are rapidly absorbed into the bloodstream after being consumed, causing sharp spikes in insulin.  They are best eaten in moderation, or just prior to moderate to intense work outs lasting longer than 30 minutes.

Complex carbohydrates include whole grains, vegetables, and fruits, and they are higher in fiber, take longer to digest, and include vitamins and minerals essential to your overall health.  Insulin spikes are slower and steadier due to the progressive absorption by the intestines.  The essential fibers help to feed the healthy bacteria in the large intestine, and promote satiety to help avoid excessive calorie intake.  These should constitute the majority of the 45-60% of carbohydrates that are eaten per day within a persons caloric needs.  


The research behind cancer and sugar

When it comes to the possible relationship between sugar and cancer, the research is interesting.  Population based studies have shown that people with the highest sugar consumption have the highest prevalence of cancer.  But is there more to this?

Since sugar is calorically dense and can easily cause weight gain, and obesity is correlated with cancer due to a myriad of reasons that include increased systemic inflammation, there could be a possible link as a result[i].

Researchers have been investigating several mechanisms that may uncover a potential connection behind sugar and cancer.  Lets explore some of the more promising theories.



One of the relationships between sugar and cancer has to do with Advanced Glycation End Products or AGES. AGES are highly unstable molecules. They are linked to oxidation and inflammation, creating unstable cellular environments, possibly conducive to the propagation of cancer cells.  We all form AGES as a normal part of aging, but since simple sugars serve as the backbone of AGE molecules, people who consume more simple sugars in their diets may have higher rates of AGE formation.  


Insulin resistance

When a cell is insulin resistant, the insulin transporter does not work to allow insulin to latch onto a cell to transport sugar from the blood into storage.  Thus, glucose remains in the blood, driving the body to release even more insulin. This is insulin resistance, and it’s this propogation that is detrimental to health, and leads to diabetes, and now perhaps cancer. 

Insulin resistance has a number of inflammatory implications in the body which include high levels of growth factors, adipokines, and reactive oxygen species that are ultimately creating a pro-inflammatory state associated with the initiation and proliferation of cancer cells.


Cancers Possibly Associated with Sugar

  1. Breast Cancer – In the case of breast cancer, the relationship seems to manifest through hormonal changes. There only seems to be a relationship with estrogen receptor-positive breast cancer.  Insulin and insulin growth factor-1 (IGF-1) associated with sugar intake lead to elevated levels of estrogen and other hormones that may contribute to tumor progression. Once diagnosed, insulin resistance may lead to a worse prognosis and a more challenging journey.  Since genetics in large part determines the risk for breast cancer, those who are genetically inclined and tend to have more IGF -1 in the blood may be at the greatest risk.
  2. Pancreatic cancer – It is unknown if insulin resistance causes pancreatic cancer, or vice versa.  A 2017 review article determined that diabetes increased risk of pancreatic cancer[ii].
  3. Lung, liver, and endometrial cancer – Recently, a certain common tumor type of lung cancer called squamous cell carcinoma has been shown to be made up of high levels of GLUT1 receptors, which have a vital connection to sugar!  Glut 1 is a main transporter of glucose into the cell, essentially the gatekeeper that allows sugar to enter.  It was discovered that these particular tumor types can survive and grow more readily, within a healthy environment of sugar, essentially feeding on the sweet stuff as it’s available.  This finding leads the researchers to assume that a lower sugar diet will help to slow the progression of this tumor, and may in fact have a direct association with sugar[iii].  


Take Home Advice

Research continues to solve the riddle of cancer, and in the case of sugar, we know too much is bad for your health, but the direct cause of cancer by sugar is still under investigation and no sincere claims can be made just yet.  However, the research is compelling, and it may be in the best interest to limit your sugar intake. 

Keep it complex! Focus your intake on the nutrient rich complex carbohydrates that include whole grains, fruits, vegetables and beans and legumes.  And if you will be having sweet treats, cereal or any other more simple form of carbohydrate, take control of your health and eat them strategically.  Consume in the beginning of the day or prior to more intense workouts, so that your body can use the sugar as fuel instead of storing it as sugar and spiking that insulin unnecessarily high.

And focus on the label.  Since the new and improved nutrition facts label is rolling into the market, the “added sugars” will be listed as a subcategory of “sugars” which will help to clarify which type of sugar is most prevalent in the food you are eating.  Keep total added sugars around 50grams or less for the day, which turns out to be about 10% or less of your total calories.

Susan started Savor Health after losing a close friend to a brain tumor and, through that experience, becoming aware of the significant unmet nutritional needs of people with cancer.  Struck by the fact that her friend was told “nutrition doesn’t matter” and “eat whatever you want,” Susan read the evidence-based literature on the subject, interviewed oncologists, oncology nurses and oncology dietitians, as well as patients and caregivers, and found that, in fact, nutrition does matter in oncology. Armed with solid scientific evidence supporting the clinical and quality of life benefits of proper nutrition, Susan left Wall Street and created Savor Health, an AI-based provider of personalized and clinically appropriate nutrition solutions for cancer patients, their caregivers and health enterprises. Susan brings to Savor Health over 25 years of industry experience in healthcare and business as well as expertise in strategy, finance and management.

Susan is an outspoken and tireless advocate for cancer patients receiving proper nutrition and nutrition support before, during and after treatment. She strongly believes that the U. S. healthcare system requires new innovation to transform it into a more holistic and integrated system of care whereby multiple disciplines coordinate care together for the benefit of the whole patient. As part of this, her goal is for nutrition to be an integral component of such an integrated cancer care delivery system.  Susan’s commitment to the field of oncology extends beyond Savor Health to volunteer work at Memorial Sloan Kettering Cancer Center in pediatrics and as a runner for Fred’s Team to raise money for research at Memorial Sloan Kettering. Susan participated in the Cancer Moonshot in June of 2016 where she was a breakout session group “igniter” tasked with starting and leading discussion. Susan’s first book, the Meals to Heal Cancer Cookbook, was published in March 2016.

In addition to her role as CEO of Savor Health, Susan speaks nationally about the importance of ensuring proper nutrition in the cancer patient and on topics including leadership and startups. She has been a speaker at the Harvard Medical School’s Career Advancement and Leadership Skills for Women in Healthcare, ESMO World Congress on GI Cancer, BioPharm America, AARP Live @50+, Lake Nona Impact Forum, and IIR ePharma Summit.

Prior to starting Savor Health, Susan had a successful career on Wall Street as a healthcare services investment banker working at prestigious firms including Donaldson, Lufkin & Jenrette, Wasserstein Perella and Robertson Stephens. Susan earned a B.A. from Duke University and M.B.A. from the University of Virginia’s Darden Graduate School of Business.
