Clinical Nutrition Report: Kids Fed Dairy 3X Cancer Risk

Here at HealthNOW’s Clinical Nutrition department we have found many of our patients to be intolerant to dairy products. More research is discovering the negative effects associated with dairy ingestion and today we’ll be discussing children, dairy and colorectal cancer.

The reaction that we see is not an ‘allergy’ in the true sense of the word, but a sensitivity or intolerance.

What’s the Difference Between ‘Allergy’ and ‘Intolerance’

Allergy – a reaction that occurs within an hour of consuming a food and the symptoms tend to be quite dramatic. E.g. Vomiting, hives, diarrhea, trouble breathing, etc.

Sensitivity or Intolerance – a reaction that occurs within several hours or days of consuming a food and the symptoms can be intense, mild or silent (meaning that you cannot ‘feel’ them but they are still damaging the body) and covers anything from digestive problems to non-digestive to degenerative changes that can lead to disease.

Individuals who have a true allergy tend to know it because the reason behind their symptoms is easy to track. If every time you drank milk you had diarrhea within an hour, for instance, it probably wouldn’t be long before you figured out the connection for yourself.

Sensitivities are trickier to spot due to the intervening time frame that can occur between ingestion and symptom development. Imagine you at a bagel for breakfast Sunday morning and Tuesday afternoon you got a headache and were quite exhausted. Would you think to ‘blame’ Sunday morning’s bagel? Unlikely, yet for many people that’s exactly the kind of scenario that occurs.

In this post I am referring to dairy sensitivities, not allergies.

As a clinical nutrition patient so aptly put it to me this morning, dairy foods and gluten foods are ‘well marketed’ and ‘positioned’ in our society. Whole wheat bread just ‘sounds’ healthy. Dairy products that are promised to ‘build strong bones’ and campaigns such as: ‘Milk- it does a body good’ are well ingrained into our society.

What If… a lot of what we’ve been told about dairy products is untrue?

What if the calcium in dairy didn’t build strong bones and what if, in fact, societies that ingested the largest amount of dairy products actually had the highest incidence of osteoporosis – meaning weakened bones?

What if the high phosphorous, protein and calcium in dairy products actually tended to prevent Vitamin D from being activated and therefore prevented the cancer prevention aspects of Vitamin D from manifesting themselves?

What if dairy products actually increased a substance in the blood called insulin-like growth factor, a known cancer causing agent?

All the above ‘what ifs’ have been documented in research studies.

Study Reveals Tripled Risk of Cancer

Getting back to children and their consumption of dairy products, a study published in the American Journal of Clinical Nutrition titled “Childhood dairy intake and adult cancer risk: 65-year follow-up of the Boyd Orr cohort” (December 2007), found that children consuming high quantities of dairy products tripled their risk of developing colorectal cancer as adults.

This was an incredibly robust study done in Scotland and England with 4,999 children. Beginning in 1937, participants were followed for two full years, and the study ended in 2005, sixty-eight years later. The almost 5,000 children were tracked based on their family’s food consumption 7 days per week. These children were then followed into adulthood up until their ultimate passing. Of the 5,000 children, 770 deaths due to cancer were recorded. The correlation of high dairy consumption and a tripled incidence of colorectal cancer was discovered.

High dairy consumption was defined as 2 plus glasses of milk per day or the equivalent in a different form of dairy.

Low dairy consumption was defined as ½ glass of milk or less per day or the equivalent in a different form such as cheese.

The correlation was independent of meat, fruit and vegetable consumption, as well as socioeconomic status.

What Should You Do?

In my family we have eliminated dairy consumption from any mammal including cow, goat and sheep. I have become convinced that milk from a mammal, other than your own mother when you’re an infant, is not beneficial for humans. If you compound the fact that we’re not really ‘designed’ to digest the milk of another mammal with the fact that the dairy products sold in this country are typically full of synthetic hormones, antibiotics and other toxic elements, you begin to see the problem.

I know that I will receive questions regarding the benefits of organic milk and unpasteurized milk. Granted, milk that doesn’t contain hormones and drugs would be better than the alternative, but you are still left with the milk of another mammal and I am convinced that is not beneficial in the long-run for optimal human health.

During the past several years we have gotten increasingly strict with our clinical nutrition patients in this regard and it has only confirmed that the above is factual. Additionally, patients who are gluten intolerant show a high preponderance of dairy sensitivities and this too is being confirmed in research findings.

I hope you find this helpful and I will continue to provide more information on this important topic as it becomes available. Unfortunately the dairy lobbies are quite powerful and such research is not happening in the numbers it needs to.

    My kids are in 4-H Food and Nutrition and according to the newest dietary guidelines (the My Plate), this “high dairy consumption” is the minimum recommended. Kids 2-4 are supposed to consume 2 cups; it is 2 1/2 cups for those 4-8 and everyone else is even more.

    It is difficult teaching something that I know is detrimental and I hate teaching “well, this is what the myplate says but it is really bad for you. You need to learn the info so you can recite it to the judges, but ignore it in real life.”

    Hello Christi,

    I understand. My children were raised much the same way. I taught them the ‘truth’ but they had to recite back some ‘untruths’ in school in order to pass a nutrition class.

    Hang in there and keep educating the truth as much as you can!

    I am hoping you can help me. My daughter is lactose intolerant or she has a milk allergy. She is almost 3 yrs. old and has recently had to go to a neurologist because of uncontrollable muscle spasms and a newer symptom of trouble walking. He is so set on Dystonia and is having her take a dopamine drug. He has pretty much said if the dopamine works she has segawa’s disease. I am not convinced this is this case. I am wondering if she not only has a milk issue but also if it could be celiac disease. I noticed mild symptoms when she was a baby and I breast feed her until she was two years old. Once I weaned her, her symptoms intensified greatly. Its hard to see her have such intense muscle spasms with no relief. Do you think Dystonia could be misdiagnosed and it really could be celiac disease?

    Hello, I understand Dairy is part of an animal so we propably don’t digest this too well but meat is also no good including fish, poultry too why can’t the gluten and dairy free people understand this? Humans are not suppose to eat animals, have you seen the suffering the animals go through at the slaughterhouse. it will break your heart. I too use to eat meat but no more my conscious won’t allow me is unhealthy and unethincal. When I did geat cheese it was organic but now I see all animal products are not to be eaten. Questions, comments?
