How to Eat to Prevent Cancer

Cancer Overview

It is estimated that one in four Malaysians (1:4) will develop cancer by 75 years old. According to estimates, there are about 90-100,000 people in Malaysia living with cancer at any one time. The National Cancer Registry of Malaysia (NCR) records 21,773 Malaysians being diagnosed with cancer but estimates that almost 10,000 cases are unregistered every year.

The top 5 cancers affecting both male and female in Malaysia are:

1. Breast

2.Colorectal (bowel)

3. Lung

4. Cervical

5. Nasopharyngeal

Prevention should obviously take precedence over treatment. The occurrence of disease is generally thought to involve two compounding factors, genetic susceptibility and environmental exposure to carcinogens. Research studies following 90,000 twins in Scandinavia suggest that environmental factors contribute more than half of the risk to the 11 most common cancers. Naturopathic support can help to reduce most lifestyle-based risk factors and even counteract some genetic risk factors.

Although cancer may appear to strike suddenly, often without warning, it does not just happen overnight. Cancer cells are once healthy cells that have become cancerous. And they are a symptom of acidity. That is, when healthy cells are corrupted by dietary and metabolic acids, they can become cancerous. The more acid we have in our bodies, the greater the risk of developing cancerous tissues.

The importance of Acid and Alkaline Balance

Healthy cells in the human body thrive in mild, moderate and high pH fluids (7.3-11pH) They do not tolerate even a mild acid state. Cancerous cells , on the other hand thrive in acidic pH of 5.5. Cancerous cells become dormant at a pH slightly above 7.365 and transform back to the microzyma or die at pH of 8.5

You need to eat, drink, and even move and think in ways that reestablish the body’s alkaline design. Much research has shown that what we eat affects our susceptibility to cancer. Some foods defend against cancerous cells and some foods promote their development.

The diet for preventing all cancerous conditions is 100 percent alkaline. You can fight the development of a cancerous condition by increasing the alkalinity of your tissues, building in a diet based around green vegetables, fresh vegetable juice, unprocessed salts, good oils and alkaline water together with nutritional supplements. You have to cut out acidic foods such as animal protein, alcohol, sugar and give up acidic habits too.

Stopping cancer in time

Understanding the timeline for cancer is crucial in suggesting methods for its prevention. Most cancers have a ten- or twenty-year interval between their carcinogenic stimulus and the appearance of a thriving tumor. The importance of diet cannot be stressed enough.

Chemopreventive agents in whole fresh foods can slow, interrupt or even reverse the course of cancer. Many of these agents have been shown to stop normal cells from becoming rebel cancer cells and some will actually even reverse cancer cells back into normal cells.

The best defense against cancer is two pronged: actively ingesting chemopreventive agents in food and avoiding cancer inducing substances in the first place. A gram of chemoprevention is worth a kilogram of cure. But how are phytochemicals likely to prevent cancer?

Eat more plants!

Plants predate animals by millions of years and they actually adapt better to environmental stress. Plants make all the anti-oxidant vitamins they need. But humans, who have either lost this ability or never had it, must rely on plants for their antioxidant properties. Many health researches promote the simple act of eating more fruits and vegetables. Ideally you should regularly consume an array of foods from the Super Eight Food Groups below.

It is important to eat foods that contain plant chemicals, not artificial dietary supplements. Unlike vitamins, phytochemicals should not be taken in the pill form found at the store. Eat organic foods rather than quick-cooking processed foods. Fresh food is better than frozen, and frozen food is better than canned. Another cancer combatant is chlorophyll, the green pigment found in the dark green plants and a necessary component of photosynthesis. Chlorophyll and related compounds are recognized as being responsible for most of the antitoxic activity of certain vegetable extracts.

Super Eight Food Groups

1. Onion group – onion, garlic, asparagus, chives, leeks, shallots and scallions All of them are antimicrobial, prevent tumours, inhibit cancer (skin, stomach, liver, colon, lung, cervix), block formation of cancer causing compounds (nitrosamine), inhibit prostaglandins that play a role in cancer.

2. Cruciferous group – broccoli, cabbage, cauliflower, kale, brussel sprouts Contains many cancer-slashing compounds like glucosinolates, indole-3-carbonol (I3C). It protects DNA and may prevent cancers of the breast, prostate, lung, throat, stomach and colon. A constant infusion of garlic and cruciferous vegetables is especially associate with reduced colon cancer.

3. Nuts & seeds – Pumpkin seeds, sesame seeds, walnuts Seeds and nuts contain strong anti-oxidants to maintain the viability of the seed. They also contain protease inhibitors that can lower incidences of breast, colon and prostate cancer. Continuing experiments have shown that protease inhibitors also hinder tumor development and can reduce the size of tumors as well

4. Grass group – rice, oats, wheat It has inhibitory effects in the presence of carcinogens. That protection is due to fiber and lignans. Lignans are anti-tumour and antiviral. Many researchers have made the obvious speculation: lower incidences of breast cancer may be due to the presence of lignans from a fibre rich diet. It could be the lignans have anti-estrogen effect and suppress the growth of cancer. The primary sources for lignans are flaxseed (linseed), rye, buckwheat, soy, millet, quinoa, oats and barley

5. Legume group – soybeans (tofu), green beans, peas Soybeans are proving to be antiviral, anticancer, antifungal and anti-oxidant protease inhibitors. Among the edible legumes, soybeans contain the highest amounts of saponins. Saponins are toxic to tumor cells, inhibit DNA synthesis in tumor cells and decreasing tumour cell growth.

6. Fruit – citrus fruits, berries The biological activity of citrus juice flavonoids covers a broad spectrum, including anti-carcinogenic and anti-tumor activities. Flavonoids prevent the invasion of cancer cells and they are potently inhibiting tumour cell growth. Raspberries and strawberries being vitamin-rich berries may inhibit cancer with tannins ( the bitter agents found in the tea, fruits, and the bark of trees)

7. Solanace group – tomatoes, potatoes, sweet potatoes, beets A tomato a day will keep cancer away! An interesting study showed a reduced rate of prostate cancer in men who frequently consumed baked tomato products in pasta dishes. The lycopene can inhibit the formation of carcinogens.

8. Umbelliferous group – carrots, celery, parsley, parsnips, fennel, cumin, coriander. Extremely rich sources of plant chemicals present in celery seed oils and in fresh celery. Animal and human studies indicate that carrots (carotenoids) inhibit cancer and have anti-carcinogenic properties. High intake of green and yellow vegetables offer protection from cancer include mouth, gastric tract, colon, lung, lining of uterus, pancreas, prostate and bladder.

Other cancer crushing agent

• All spices – turmeric, ginger root, licorice, rosemary, basil, bay leaf, cinnamon, caradamon, cumin, nutmeg, oregano, sage, thyme.

• Tea – Cathechin from green tea and thea flavins from black tea

• Super green food – Wheatgrass contains more than 100 food elements, including every identified mineral and trace mineral and every vitamin in the B-complex family. It has one of the higher pro-vitamin A contents of any food and is rich in vitamins C,E, K. Wheatgrass juice is 25% protein, a higher percentage than in meat, fish, eggs, dairy products or beans. It has high amounts of anti-fungal, antimycotoxic substance call laetrile.

• Barley grass- 4 times as much thiamine (vitamin B1) as whole wheat flour, 30 times as much as milk. It has 7 times vitamin C than oranges. • LingZhi – Immune strengthening agent

Tips for Success

• Everyday include fresh choices from as many of the Super Eight Food Groups as possible. Do not accept canned and processed food that have been stripped of chemopreventive agents, nor the false assurance of pills and extracts.

• Try to consume a plant based diet rather than a meat based diet.

• Do not eat overcooked or burnt food or foods cooked at searing temperatures. Preferred cooking methods include steaming, boiling and light baking.

• For cooking use only sesame seed, olive oil.
