The Facts on Food and Cancer – Part 1

Take a stroll through any large supermarket . . . shelves groaning, freezer cabinets piled high, aisles stretching into the distance. While the goods on display look appetising enough, it is the labels that attract attention – NO ADDED SUGAR; HIGH IN FIBRE; SALT REDUCED; LOW IN CALORIES; NO ARTIFICIAL COLOURS, FLAVOURINGS, PRESERVERS OR ‘IMPROVERS’.

The labels are signposts of our times, reflecting the growing consensus among medical researchers that small changes to diet can have a big impact on health. Encouragingly, the same alterations that seem to benefit our hearts, waistlines and general fitness also seem to reduce our cancer risk. Indeed the three leading causes of death in Australia, heart disease, cancer and stroke, as well as prevalent debilitating conditions including adult-onset diabetes, diverticular disease, weight disorders and liver cirrhosis, can often be prevented . . . with dietary change a key strategy.
The influence of diet on cancer is considerable. Scientists estimate that diet is a major contributory factor in about 35 per cent of all cancer deaths. Thus, of the 22 000 people who die of cancer in Australia each year, no fewer than 7700 deaths are reckoned to be diet-related. The most prevalent cancer killers among Australian men are those affecting the lung, bowel (colon and rectum) and prostate. In women, the ‘big four’ are breast, bowel, lung, and reproductive organs (particularly the uterus and ovaries).
World authorities on cancer trends and causes consider that diet could play a major part in as many as 70 per cent of breast cancers, 70 per cent of cancers of the endometrium (lining of the uterus), 61 per cent of cancers affecting the bowel, and 96 per cent of those affecting the prostate. And, in the case of lung cancer – one of the biggest cancer killers of men and, increasingly, of women -dietary imbalance appears to enhance the damaging effects of tobacco. Thus smokers who neglect fresh fruits and vegetables have a lung cancer risk that is somewhat higher than that of their counterparts who regularly eat these foods.

Cancer authorities worldwide consider dietary modification to be one of the most constructive ways by which individuals can reduce their cancer risk. Based on current evidence, the measures most likely to achieve this end include eating a diet that has plenty of variety and is low in fat, minimising the intake of smoked and salt-cured foods, ensuring that meals include fruits, vegetables and whole grains every day and drinking less alcohol. For the one in three Australians who develop some form of serious cancer during their lifetime, doctors recommend a similar dietary strategy in the lead-up to treatment. Improving nutritional status prior to anticancer therapy does not guarantee success but it is certainly a practical step that patients themselves can take towards helping their bodies cope with the impact of treatments such as surgery, radiotherapy and chemotherapy.

Why choose high-fibre foods?

In recent years, the message from medical research has become increasingly clear; a diet rich in high-fibre foods (such as fruits, vegetables and wholegrain cereals) protects against several common disease conditions. It also assists in controlling weight as high-fibre foods are ‘calorie bargains’, that is wholesome, low-calorie substitutes for fatty foods.
Several epidemiological studies have suggested a protective effect of fibre-rich foods in populations with low rates of bowel cancer. Scientists are particularly encouraged by the findings of Japanese research based on a very large population sample showing a direct relationship between daily consumption of green and yellow vegetables and low rates of cancer at most sites.
Many Australians eat far less fibre than the 25 g to 30 g daily recommended by nutritionists. Even rich sources of fibre contain only about 6 g per serve. Thus eating the proverbial ‘apple a day’ is far from adequate; four or five servings or portions of high-fibre foods are advisable. Excellent sources of fibre include beans, dates, nuts, prunes, berry fruits, apples, oranges, pears, bananas, apricots, figs, bran cereals, corn ears, peas, spinach, potatoes, lentils, brussel sprouts, parsnips and wholegrain breads. Although it is uncertain whether fibre itself confers nutritional benefits, it clearly assists body functions related to cancer risk. In particular, fibre speeds the passage of food through the digestive system, influencing rates of nutrient absorption and of waste excretion. Such influences appear to benefit the bowel environment, apparently reducing the risk of cancer.
The vitamin A and C groups and minerals found in small quantities in many fibre-rich foods also seem to play an important role in cancer protection. Fruits and vegetables rich in these vitamins (as well as fibre) include broccoli, cantaloupe, carrots, cabbage, cauliflower, kohlrabi, turnips, spinach, squash, sweet potatoes, peaches, plums, tomatoes and watermelon.

Nutritionists consider the best way to obtain such micronutrients is within whole foods rather than separately in high dose tablets or liquid preparations. They argue that mega-doses of vitamins and minerals can create dietary imbalance and may even prove toxic when taken in excess.
To gain maximum nutritional value from fruits and vegetables, eat them fresh where possible; cook vegetables complete with skins; steam or bake fruits and vegetables, rather than boiling them; and reduce cooking time to the minimum.
