Health - Cancer's New Status
By Diane Herbert, ND

The diagnosis of cancer strikes fear in the minds of millions of people worldwide every year.1 For many years heart disease was labeled as the number one killer in the United States, but recently that has changed. In January 2005, cancer surpassed heart disease as the number one killer of Americans under 85 years.2 Globally the World Health Organization projects that global cancer rates could increase by 50 percent by 2020.3 Thus there is good reason to be concerned. However, research also shows that we can do something to significantly reduce our risk of having cancer.

 

Globally, tobacco usage was the cause of the death of millions during the last century. Half of those who regularly smoke are killed by tobacco related diseases (cancer, lung disease, and heart disease), and one quarter die prematurely. Lung cancer in regular tobacco users is drastically higher (20 to 30 fold), and cancers of the oral cavity, esophagus, and upper digestive tract are significantly higher (2 to 6 fold). Even passive or secondary tobacco smoke increases lung cancer risk by 20 percent. Thus tobacco is a very dangerous, but avoidable, cancer risk. Of course, it is best to never start smoking; however, there is clear evidence that stopping smoking significantly reduces the chance of getting cancer. The greatest reduction is seen when a person stops smoking in their early 30s, but significant risk reduction is seen when a person stops smoking even after age 50.4

 

Diet is also a significant risk factor. Many studies have been conducted showing that the kind of diet we eat has a significant impact upon our cancer risk. We shall look at some of these studies.

 

In one study of 190,545 participants who were followed for seven years, researchers found that those who regularly ate red meat (beef, pork, lamb) had a 50 percent increase in pancreatic cancer risk (a very serious form of cancer), and those who consumed processed meat (sausage, salami, bologna) had a 70 percent increase.5

 

Another study looked at ovarian cancer. This Canadian study followed 2,500 women, and researchers found that those with the highest cholesterol consumption had a 40 percent increase in ovarian cancer risk compared to those with the lowest cholesterol consumption. Even those with the highest egg consumption had a 30 percent increase in risk. Cholesterol is found only in animal products (meat, eggs, dairy including cheese, etc.) and not in plant foods. It is interesting that this same study showed that the women with the highest consumption of total vegetable intake, including cruciferous vegetables (kale, collards, mustard greens, turnip greens, turnips, radishes, rutabaga, cabbage, bok choy, cauliflower, broccoli, Brussels sprouts, watercress, kohlrabi), had a reduced cancer risk by almost 25 percent.6

 

A large study following 148,610 people for over 20 years showed that those with the highest meat intake had approximately a 50 percent higher colon cancer risk compared with those with lower intakes. The researchers concluded that the less red and processed meat people eat, the lower was their risk of colon cancer.7

 

A review of 21 studies showed a relationship between dairy product consumption (skim milk, low-fat milk, whole milk, yogurt, cheese) and ovarian cancer risk. Study reviewers found that for every 10 grams of lactose (about the amount in one glass of milk) consumed daily, ovarian cancer risk increased by 13 percent.8 Thus a person consuming two glasses of milk or equivalent will have an increased risk of 26 percent, ingesting three glasses or equivalent will have an increased risk of 39 percent, and the risk continues to escalate as consumption increases.

 

A Canadian study compared data from men with testicular cancer to healthy individuals. After examining nutrients, food groups, and particular foods, researchers concluded that a high intake of dairy products (particularly cheese), baked goods, and luncheon meats, could contribute to this cancer.9

 

Harvard researchers analyzed 90,655 premenopausal women enrolled in the Nurses’ Health Study 11. They found that animal fat intake, especially from red meat and high-fat dairy products during premenopausal years increased the risk of breast cancer.10

 

One of the most prestigious studies on diet and health is The China Study. It is widely considered the most comprehensive study of diet, lifestyle and disease ever completed. It was headed by T. Colin Campbell, and he makes this very interesting comment: “My fellow researchers and I determined that plant-based diets are the main reason there are such low rates of heart disease, diabetes, and cancer in certain areas of rural China. In contrast, even small amounts of animal protein-based foods [meat, fish, poultry, milk and milk products, and eggs] increased the risk of many diseases.”11

 

Other studies also consistently show that plant foods prevent or inhibit cancer; such as avocados inhibit prostate cancer,12 oranges and bananas may reduce childhood leukemia,13 and fruits and vegetables lower pancreatic cancer risk.14 The message for reducing the risk of cancer seems to be the same over and over and over again: eat little or no animal products and eat a plant based diet. In other words, the less animal fat and protein you include in your diet, the less your risk of cancer. You will notice that each of the studies cited above looked at one kind of cancer. Researchers often limit a study to one particular problem because of the very nature of study design. However, the fact that we see the same message being repeated for so many different types of cancer, we can logically conclude that the message will be the same for all types of cancer: eat a plant-based diet and your risk of all types of cancer will decrease.

 

Another major determinant in whether or not you will get cancer is the health and vitality of your immune system. Every day our bodies produce about 300 abnormal cancerous cells, and more if we are exposed to carcinogens. However, a healthy immune system will quickly identify and kill these cancerous cells.15 The consumption of simple carbohydrates (sugar) distinctly suppresses the immune system. Ingesting 100 grams (25 teaspoons) of sugar (table sugar, sugar cane crystals, fructose, glucose, maltose, etc.) at one meal or snack suppresses the immune system for the next five hours. Even the consumption of 24 grams (6 teaspoons) reduces the body’s ability to destroy bacteria.16

 

In 2003, per capita sugar consumption in the United States was 142 pounds,17 which works out to about 43.5 teaspoons per day (142 lbs. per year x 16 oz. x 28 [ounce to gram conversion] / 365 days / 4 grams = # of teaspoons per day).18 Soda pops and many sweet desserts have 10 teaspoons of sugar, and many candy bars, cookies, and donuts can have 6 or more teaspoons of sugar. Many fat-free items have simply replaced the fat with sugar to maintain a taste that Americans will buy. Also, sugar is added to many things to which you would not think it would be added. Just look at the ingredient list of items you buy, and notice if and how much sugar is added. Also, notice how near the top these sugars are listed. Then look at the Nutrition Facts label and look for the quantity of sugar in the item. Remember that 4 grams of sugar equals 1 teaspoon of sugar. If you see, say, 15 grams beside “Sugars,” that means there are almost 4 teaspoons of sugar per serving in that item. If you start to look at the Nutrition Facts labels of the things you consume, you may just be surprised how much sugar you do eat on a daily basis. (Also, be aware that fruits and vegetables often have naturally occurring “sugar,” which will be included in the quantity of sugar given in the Nutrition Facts label. That is why it is also good to look at the ingredient list to find out the source(s) of the sugar and its relative amount to the other ingredients.)

 

The bottom line is that it is easy to see that the vast majority of Americans have chronically suppressed immune systems through excessive consumption of sugar. And the fact that many eat donuts for breakfast, drink soda pop instead of water, have candy bars for snacks, and love to have a nice dessert for dinner, the immune system is just not able to function at a level to protect against the cancerous cells all of us develop in our bodies every day. If these cancerous cells are not identified and killed by the immune system, they are left to grow, and after a few years you are diagnosed with a tumor or cancer.

 

Even though cancer is now the number one killer of Americans under age 85, there are things that we can all do to drastically reduce our risk of cancer. Eliminating tobacco usage by those who smoke is a major step in cancer risk reduction. Moving from a diet containing animal fat and protein to a plant-based diet is repeatedly shown to provide major cancer risk reduction benefits. Finally, drastically reducing our intake of sugar will help give our immune systems the ability and vitality necessary to identify and kill the abnormal cells in our bodies and not allow them to reproduce to form the basis of full-blown cancer. Certainly there are things that we can do; therefore, let us do all that we can to reduce the risk of cancer in our lives and in the lives of others.
