Why cannot eat sugar?
There has been a lot of talk about sugar and cancer, and for a good reason. It is an indisputable fact that cancer cells consume (i.e., metabolize) sugar (glucose) at a much faster rate than normal cells do. This is precisely how a PET scan (positron emission tomography) works: first, you drink a glass of glucose [FDG (fluorodeoxyglucose - a radioactive drug) tagged to glucose to make a radiotracer], and then the scan detects where that glucose is being metabolized the fastest in your body. Those glucose "hot spots" are the areas in your body that are most likely cancerous. While researchers are still not clear whether a high-sugar diet causes cancer, what we do know is that once cancer cells are in your body, they consume anywhere from ten to fifty times more glucose than normal cells do (O. Warburg, 1956). Therefore, it makes logical sense for cancer patients to cut as much refined sugar from their diets as possible, in order to avoid "feeding" their cancer cells, and instead rely on the glucose found naturally in vegetables and fruits.The connection between cancer cells and sugar was first discovered in 1920s by a doctor named Otto Warburg. Dr. Warburg won a Nobel Prize for discovering that cancer cells get their energy and breathe (i.e., respirate) differently than healthy cells do. Specifically, he noticed that cancer cells get their energy by breaking down unusually large amounts of glucose and that they also breathe without oxygen (known as "anaerobic" respiration). Healthy cells, on the other hand, break down a much smaller amount of glucose and breathe with oxygen (known as "aerobic" respiration). What's interesting is that cancer cells will still breathe anaerobically even when there is plenty of oxygen around. This led Dr. Warburg to hypothesize that cancer cells must have something wrong with their mitochondria, since that's the part of the cell where aerobic respiration takes place in healthy cells. The point is, cancer cells behave differently than healthy cells do, and one of the key differences is that they require lots of sugar in order to function. Therefore, cutting refined sugars out of your diet may be a key way to help "starve" a cancer cell.
Why must avoid dairy products?
There are two main reasons why cancer patients should reduce or eliminate dairy products from their diet. The first is that dairy is the breast milk of another animal, which means it is packed with hormones and proteins meant to make a baby calf grow- not humans. (Incidentally, we are the only species on the planet that drinks the breast milk of another animal.) What's more research has shown that the main protein in cow's milk, called casein, makes cancer cells grow, both in petri dishes and in lab rats. In fact, researchers have found that they can turn a rat's cancer on or off simply by feeding, or not feeding, it casein (Dunaif and Campbell, 1987). The second reason why dairy products should be avoided if you have cancer is because dairy products contains unhealthy chemicals such as bovine growth hormones, antibiotics and pesticides.
Finally, it is important to remember that dairy products do not provide us with any nutrients we cannot get elsewhere, even though TV commercials may try to convince us otherwise. For example, we can get just as much calcium from leafy greens and turnips and just as much protein from beans and nuts. Taken together, the evidence is mounting to show that dairy may be cancer promoting, whether due to its inherent casein protein or to the bad things we add on it during production. That is why so many cancer patients drastically reduce or eliminate their dairy consumption, at least until their cancer is completely gone.
Why cannot eat meat?
There is an argument that we humans are designed for a diet that consists of only 10 percent meat, which ideally should be wild, lean meat. Today, our diet consists of 15 percent meat. On the other end, proponents of the Paleo, or "caveman," diet would argue that humans were designed to eat 20 to 40 percent meat. Regardless of what humans were eating thousands of years ago, at present we are dealing with the modern disease of cancer, and the fact remains that scores of large-scale, well-designed scientific studies have linked regular consumption of meat, especially red meat, to many types of cancer (M.Salehi et al, 2013). In fact, one study showed that eating just two servings of meat a day quadrupled a woman's risk of breast cancer recurrence (J.R.Hebert et al, 1998). In addition to these alarming findings, the meat, poultry, and fish industries have the same issues as the dairy industry when it comes to the unhealthy additives of artificial growth hormones, antibiotics, pesticides, and omega-6 fats. And, as with dairy, there is no nutrient in meat that you cannot get from other sources. For example, vegetarians can get plenty of protein by eating beans along with whole grains and all the iron they need from beans and seaweed.
Why cannot eat processed foods?
Therefore, in order to keep blood sugar and insulin levels low and stable, refined foods should be reduced or eliminated altogether. Try instead to eat carbohydrates in their whole forms. Your body digests whole grains much more slowly than refined grains, which helps to keep your blood sugar and insulin levels low. In addition, whole gains have more fibers and vitamins than refined grains do (Q.Sun et al, 2010). Perhaps most important, eating whole grains has been consistently linked with lower cancer rates (A.Schatzkin et al, 2007). Examples of whole grains include brown rice, rye, quinoa, whole barley, and wheat berries. For bread, you could try sprouted-grain bread, which is denser and has much less sugar per slice than both white and whole-wheat bread.
In a nutshell
If you have cancer, your eating habits must change. If all the above facts fail to convince you that eating meat and dairy products is not good for cancers, at least understand what happens behind the scene of this meat and dairy industry...and if you are still a happy consumer after watching this video clip, it is really your personal decision.
