More on Dairy and Cancer

Any diagnosis of cancer is a terrifying event for anyone to go through. Here, I am trying to arm you with useful information so that you can be proactive regarding your health.

Warning: you will find this information hard to believe especially when you realize this flies right in the face of decades inundated with slick marketing campaigns telling you the exact opposite of what these scientific study results.

Bovine Leukemia, Milk and Cancer

Ever heard of Bovine Leukemia Virus? Neither had I until I started researching milk. Gertrude Buehring, Ph.D., wanted to know if humans could be infected with Bovine Leukemia Virus (BLV). Evidence was found of Bovine Leukemia Virus DNA in 9 out of 22 volunteers. We found evidence of BLV proteins in breast tissues from 8 of 26 patients. Antibodies to BLV were found in the serum of over half of the 100 human volunteers tested. These preliminary results suggest that humans may be infected with BLV. (Added emphasis.) [1]

Another investigator, Robert Cohen has this to say about bovine Leukemia. “I knew that bovine leukemia is a problem, but I had no idea of the extent of that problem. According to the ad, 89% of the dairy herds in the United States have cows infected with leukemia.” Robert Cohen

Can you imagine my horror when I first learned of this?  My daughter was at the end of her first year of leukemia treatment when I read this information. If a virus can mutate our genetic code does this means that Bovine Leukemia Virus could cause leukemia or other cancers in people?  I shudder to think of this…

Robert Cohen researched Bovine Leukemia Virus and said the following; “If the bovine leukemia viruses causes human leukemia, we could expect the dairy states with known leukemic herds to have a higher incidence of human leukemia. Is this so? Unfortunately, it seems to be the case! Iowa, Nebraska, South Dakota, Minnesota and Wisconsin have statistically higher incidence of leukemia than the national average. In Russia and in Sweden, areas with uncontrolled bovine leukemia virus have been linked with increases in human leukemia. I am also told that veterinarians have higher rates of leukemia than the general public. Dairy farmers have significantly elevated leukemia rates. Recent research shows lymphocytes (a small white blood cell) from milk fed to neonatal mammals gains access to bodily tissues by passing directly through the intestinal wall.“

Synthetic Hormones in our Live Stock 


I am sure you have heard about hormones in meat.  But did you know that these have been scientifically studied and linked to cancer?

Estradiol (E2 or 17β-estradiol) (also oestradiol) is a sex hormone. Estradiol is the predominant sex hormone present in females. It is also present in males, and at a higher level because it is being constantly produced. In human females it is only produced 3 out of 30 days of the cycle. It represents the major estrogen in humans. Estradiol has not only a critical impact on reproductive and sexual functioning, but also affects other organs including the bones. [3]

Two scientists from the University of California Santa Barbara have researched two genes, BCL2 and P53, and their effect on female-specific cancers and prostate cancer.  Cells of breast, endometrium, ovary and prostate, were grown in the laboratory. Estrogen (estradiol) was added to the cells. This hormone turned on the BCL2 gene, causing the cells to grow rapidly and not die. [4]

Definition of BCL2 Gene: A gene associated with non-Hodgkin’s lymphoma that normally helps regulate the life span of a white blood cell
but when mutated prevents such cells from dying, allowing possible further mutations and the development of cancer.

Sixty-three percent of American beef is banned by Europe because of the industry’s traditional use of growth-promoting hormones, according to a report from the Congressional Research Service (CRS). [5]

I was able to question a Dr. Hermenes about this subject. He told me that synthetic hormones are a problem because they disrupt endocrine receptors.

Wikipedia has the best definition of endocrine disruptor as follows: Endocrine disruptors are exogenous (outside the body) substances that “interfere with the synthesis, secretion, transport, binding, action, or elimination of natural hormones in the body that are responsible for the maintenance of homeostasis (normal cell metabolism), reproduction, development, and/or behavior.”  They are sometimes also referred to as hormonally active agents, endocrine disrupting chemicals, or endocrine disrupting compounds (EDCs).

Let’s look at the endocrine system for better understanding of this subject.

The illustration above is a cursory glance at the endocrine system which actually relates to many other organs and systems of the body. For a more further study you can look at wikipedia‘s article. Even just going through the page will give you a better idea of how important the endocrine system is and when it gets interrupted what impact it could have on your daily life.

When livestock are allowed to eat their normal food such as grass, the greens in their system turn into vitamins that we would get when we eat that type of meat. This is no longer the case in the United States. Few North Americans understand how different the taste of their meat is due to corn and soy as feed. It has been discovered that beef cattle given hormones will eat less yet put on weight. Profits are fueled by increased weight at the time of slaughter.

How many humans have you heard complain that “I eat less but continue to put on weight. I don’t understand why?” The underlying reason could be synthetic hormones added to our livestock.

What a thought…

What’s the Solution?

The only solution is to consume smaller portions of meat, like the inside size of your palm on your hand. Not the outer rim or going all the way to the edge of your hand. Three to four ounces of meat at a time for an adult.  Any meats should be minimally processed, i.e., free range. Beef should be 100% grass fed, chicken should be organic. Fish should be wild caught. When livestock is allowed to eat naturally their meat will be more nutritious. Grass provided greens that literally turn into vitamins in their bodies and also provide healthier fats. When animals are fed only corn and soy, their meat will be more acidic and have far less nutritional value for the body. We have to make up this difference by eating far more vegetables than in times past.

There are also food combinations that provide complete protein. Here are some examples.

Red beans and rice. Black bean soup with whole grain rolls. Corn chips and bean dip. Quinoa and black bean casserole. Rice salad with white beans. What do these dishes have in common besides the fact they all contain beans? They’re all pairings of beans and grains.

While these dishes are modern renditions, bean and grain combos have a rich history in ancient culinary practices, long before nutrition scientists discovered the health benefits of beans and whole grains or the protein boost provided by combining different plant proteins to get all nine essential amino acids. [7.]

Learning and experimentation with food is the only way to figure this out.

I learned about this subject during the first year of Kayla’s leukemia treatment and was horrified by the information. After a bout of hospital stays with high fevers and the doctors trying to find her infection that caused this recurrent fever, they found a sinus infection deep in her sinuses. I had already reduced her dairy intake and decided to get our whole family off of dairy immediately. The results were astounding and ten years later we are still dairy free. The health benefits far outweighed the taste losses.  Try it for two months minimum as laid out in The China Study book, by T. Colin Campbell. No dairy, butter, yogurt, in any form for two months! Read all labels. Whey in protein shakes comes from dairy. Casein is the protein in milk and is considered dairy so put that word onto your dairy-label- watch- list.  It takes some work and effort but long term is totally worth it. A life time of horrible migraines on a regular basis are gone for me as a result of quitting all dairy. Many people quit dairy and find that their serious acne disappears.  I wonder what your results will be?
