Nutrition & Cancer: Understanding the Power of Information

Nutrition & Cancer: Understanding the Power of Information

90-95% of all cancers are a result of lifestyle factors, dietary eating patterns, environmental toxicants, and infections, while the remainder 5-10% are due to true genetic defects (Davoodi, Esmaeili, & Mortazavian, 2013). In other words, the environment you live in, the food you eat and drink (plus all the contaminants it contains), and your lifestyle are the biggest determinants of your cancer risk and quality of your lifespan.

The food you eat, break down, and absorb ultimately directs physiologic processes within and among cells. Lifestyle factors that predispose one to duplicating cancer cells can be thought of similarly, since day-to-day inputs often send the wrong message to our cells. An inadequate cell that cannot overcome the insult becomes collateral damage. One cancer cell goes unnoticed to us, but not to our body. 

For example, excess alcohol, animal protein, and caffeine use in an already susceptible individual can signal inflammatory pathways that hinder the body’s ability to function normally. Physical inactivity, insufficient daily sleep, and emotional unrest can create a constant state of stress which trigger the same inflammatory pathways as toxic environmental toxicants derived from many food and recreational sources.  When one’s diet is nutrient-poor and loaded with GMO crops (i.e., wheat, corn, soy), saturated fats (derived primarily from animal protein and nuts), processed food and sugar, it directly contributes to mental, physical, and emotional sluggishness. The cells begin to starve and remain in a constant state of terror. Cells receive the worst sources of information for maintaining normal cell functions.  

It is estimated that 30-40% of all cancers can be prevented by diet alone (Davoodi, Esmaeili, & Mortazavian, 2013). Realistically, people are not receiving this information in regards to cancer prevention and when diagnosed with cancer. There are valid reasons for this, with marketing taking the prize of misinformation.

Once approved in 1993, rBGH has been injected in 1 in 6 U.S. female cows causing an increase in milk production by 20%.  The USDA, whose board members consist primarily of representatives from agriculture and industry, needed to now create a high demand for dairy products domestically and internationally.  The USDA created a highly coordinated national campaign and research programs to build just this demand. 

There are several books that describe, in great detail, the link between milk consumption and cancer. Some of my favorites are The China Study by T. Colin Campbell and Thomas M. Campbell II, and Your Life in Your Hands by Jane A. Plant.  The 20+ year research studies have clearly demonstrated the carcinogenic effects of milk amongst many others associated health problems. 

When the Federal Trade Commission finally asked the USDA to investigate its scientific basis of their claims made by the milk moustache ads, the USDA had to admit they had “no proof”.  In 1999 the United Nations ruled to not endorse rBGT milk and has since placed an international ban on US milk. Despite all of the research which has clearly shown there is no nutritional benefit and actually more health risk associated with milk consumption, the FDA, World Health Organization, and National Institute of Health continuously state milk products are safe for humans exclusively because of economic reasons. 

Cancer doesn’t happen overnight. It is a long-term process that can go years unnoticed.  When we focus on one specific component and look for a relationship, we are entirely disregarding the hundreds of other components that increase one’s cancer risk.  

At the intersection of nutrition and cancer, other dietary factors must be considered.

  1. Blood sugar:  Both elevated glucose and insulin levels (remember, insulin is given to “correct” high blood sugar in diabetics) set the stage for the unchecked growth of cancer cells (Amadou 2013). Our bodies were never designed to consume the amount of sugar we do on a daily basis. More on this here.

  2. Excess weight:  Central obesity (“tummy fat”) increases the risk of dying from breast cancer by 34%, and is a source of excess estrogen that fuels many cancers (Amadou, 2013). Excessive body fat, weight gain and/or obesity is responsible for one of every five diagnoses of cancer in the U.S. (Bähr, 2017). Losing weight by correcting your diet improves natural killer cells, critical components of a robust immune system (Bähr, 2017). The ideal cancer host is an obese (i.e. inflamed) individual, living on packaged foods, and using popular skin care products that contain estrogen-like chemicals. Returning to a healthy weight helps reduce risk of cancer.

  3. Alcohol:  Although many people have heard that small amounts of wine may be cardioprotective, it’s a mistake to assume the health benefits of alcoholic beverages can be extended to non-cardiac diseases. The more a person drinks alcohol, the higher the risk for breast, gastric, and pancreatic cancers (Brennan 2010; Ma 2017), likely due to the fact that alcohol blocks liver function—including removal of excess estrogen, which we know promotes cancer growth (Hankinson et al., 1994).

  4. Move:  Regular physical activity reduces the risk of dying from all cancer types. Risk of breast cancer decreases by 3% for each 4-hour-per-week spent walking at 2 miles per hour or 1-hour-per-week spent jogging at 10-minute miles. Risk of breast cancer decreases 5% for more vigorous exercise (Wu 2013). Low intensity, longer duration and high intensity, shorter duration physical activity can increase the quality and length of one’s lifespan by protecting against all causes of illness and death (Kopperstad 2017). In other words, it doesn’t matter what you do, it matters that you do. If swimming isn’t your thing, that’s okay. Moving in a way that you love is an excellent way to stress less. There’s no wrong option when you’re moving.

  5. Don’t fear the sun:  Vitamin D is an excellent cellular communicator and deserves a book on it own.  Not only does it have the ability to poke holes in certain viruses, but it also regulates the cell’s ability to break down and recycle dysfunctional or unused parts in a process called autophagy (Tavera-Mendoza, 2017). This is critical when cells become sick. Doctors worldwide measure vitamin D status by assessing 25-hydroxyvitamin D (25[OH]D), a prohormone that is produced in the liver (via hydroxylation of vitamin D₃ by the enzyme cholecalciferol 25-hydroxylase). 

  6. Sleep:  Too little sleep (under 7 hours per night) or too much sleep (more than 10 hours per night) is associated with a higher risk of death from all causes (Collins 2017). Individuals who habitually sleep less than 6 hours nightly had a 62% greater risk of dying from cancer than those who snooze at least 7 hours each night.

  7. Restore the thyroid:  Repairing years of damage to one of the most sensitive organs, the thyroid, and balancing thyroid hormone levels can be done with diligent work and effort. It’s better to do this naturally rather than take thyroid hormone medications. While hypothyroid individuals have greater risk of cancer, it’s worth considering the possibility that thyroid hormone treatment may increase pancreatic cancer cell division, migration, and invasion, and reduce the chances of beating cancer (Sarosiek 2016). This cannot justifiably be generalized to people without cancer, but research efforts should focus here in the future, as with estrogen hormone levels and breast cancer.
