Attitudes to the link between diet and cancer are changing fast. The World
Cancer Research Fund was founded specifically to fund and sponsor education
and research into the diet-cancer link. There is mounting evidence that the
high fat intake in a typical Western diet, along with the low intake of
nutritious foods such as vegetables, fruits and wholegrains, may be responsible
for up to 35% of cancers.
The World Cancer Research Fund is the only major national charity concerned
with the link between cancer and food, nutrition and lifestyle factors. Their
report Food, Nutrition and the Prevention of Cancer: a global
perspective gives guidelines consistent with those published by the
World Health Organisation, the E.U. Europe against Cancer initiative
and other authoritative organisations. The idea of an anti-cancer
diet promotes prevention by strengthening the immune system directly
and has partly led to the promotion of a five a day campaign
for fresh fruit and vegetables.
The intensification of agricultural practices has led to a decline of between
25% to 75% in the levels of key mineral nutrients in farmed vegetables over
the last 60 years. There has also been a rise in farmed fruit sugar levels,
so much so that some natural fruit juices now contain as much
sugar as a fizzy drink.
If we can source quality food, our cooking methods often destroy the nutritional
content. Studies show that fresh, uncooked vegetables strengthen the immune
system and increase resistance to many diseases. Cabbage placed in cold water
and boiled loses about 75% of its vitamin C content. Similarly fresh peas
cooked for only five minutes lose 20-40% of their Thiamine content and 30-40%
of their vitamin C. About 50% of vitamin E is destroyed by frying or baking
food.
Tests in Spain recently measured the levels of flavonoids (a kind of antioxidant)
left in fresh broccoli after it was cooked. The results show large differences
in flavonoid content according to how the broccoli was prepared. The cooking
methods were:
boiling - 66% loss
pressure-cooking - 53% loss of major antioxidant
steaming - minimal loss of antioxidants
microwaving - 97% loss of flavonoids
Scientists in Finland found that blanching and deep-freezing vegetables destroyed
beneficial compounds. Blanching prior to freezing destroyed up to one-third
of the vitamin C content of vegetables and more was lost in storage. The
healing properties of uncooked foods are being increasingly recognised in
natural cancer therapies.
The more we let food industries create what we eat the more likely we are
to be at risk from diet related problems. In effect the commercial interests
of food manufacturers are systematically robbing unwary shoppers of health,
and eventually life. The more control and information we have in sourcing
pure foodstuffs, the less at risk we are from dis-ease for nutritional reasons.
One of the first steps in finding a healthy diet is changing how and where
we shop and sourcing foods we can trust. The supermarkets give us thousands
of choices but few options. Try to find for example, one of the many varieties
of biscuits available that do not contain hydrogenated vegetable
oil.
Too much protein in a diet is also harmful to health and can promote cancer.
Meat and sugar-rich diets are common in the West. These are often overcooked
or over processed. When cooked or processed foods are eaten our white blood
cells (leukocytes) rush to the intestine to help with digestion. As a result
other parts of the body may be left undefended from attack by germs and viruses
after a heavily synthetic meal.
Biological enhancement of crops, growth hormones in milk and meat, mercury
in our mouths, colorants and carcinogens in food are commonplace. The foot
and mouth epidemic, B.S.E. in sheep and cattle, nuclear radiation and the
de-naturalisation of our food are examples of how common sense is abandoned
to profit. The Precautionary Principle is too often being overlooked
in the rush of science.
The genetic modification of foodstuffs for example is still largely untested
and many of its results are open to interpretation. Scientific knowledge
of the processes involved is actually at an early stage. Little is known
about side effects, how gene function is controlled, gene transfer into other
organisms such as bacteria in the human gut. The British Medical Association
(B.M.A.) has said that the potential adverse effects have not been sufficiently
investigated and strongly recommend caution. The United Nations safety
body, the Food and Agriculture Organisation, has warned that the failure
to carry out full health checks on G.M. foods could lead to toxic reactions,
allergies and increased resistance to antibiotics.
Experience has shown that genetically modified and organic foods cannot exist
together because genetically modified crops will cross-pollinate with any
others. Contamination of the whole food chain has already occurred within
a couple of years. Biotechnology companies that are facing opposition in
Europe are targeting less well resourced countries such as India in the hope
that genetically modified organisms will spread irreversibly before public
opinion has time to intervene.
In addition to avoiding the carcinogens that are increasing everywhere in
our culture, we need a complex yet balanced mixture of specific minerals
and nutrients to maintain ourselves in a healthy way. Recent government policy
recommends we should eat a minimum of five or six fruit and vegetable types
in any given day. The British Dietetic Associations survey shows that
the typical English diet includes only 3.3 portions of fruit and vegetables
a day. The Scottish consume 2.7 portions a day while the Irish get only a
measly 2.3. New research from Spain suggests that the quality of food and
its method of preparation are as important as the quantity, since many of
the nutrients in food are destroyed during industrial preparation and even
in domestic cooking processes. In order to gain the breadth of specific minerals
we need to maintain health using food, we need fresh, quality food types,
cooked appropriately, or at least someone to sell us the right supplements!
The quick-fix mentality of Western culture has grown so used to pill-popping
supplements that markets have responded to this. The American public uses
increasing amounts of vitamin and mineral supplements. A survey conducted
by the Federal Drugs Authority (F.D.A.) in America states that over 60 million
Americans believe that vitamin supplements are essential for good health.
The report also shows that about 20 million Americans believe that mineral
deficiency is a primary cause of disease, including cancer, which shows what
a good marketing job the supplements industry has done. Drug corporations
are moving quickly into the supplements industry following market forces.
Legislation in Europe is posed to ban many supplements (like herbs) that
have a natural source, in preference to pharmaceutical alternatives. Even
though appropriate dietary supplements are becoming recognised as a useful
tool in maintaining health, legislation is fast catching up to regulate this
field, showing a clear preference to synthetic chemicals.
In 1980 the National Academy of Sciences Committee on Dietary Allowances
(who established R.D.A.s or Recommended Daily Allowances) found no
scientific evidence for nutritional benefits from vitamins, minerals or trace
elements in dosages greater than those supplied by a balanced diet. Supplement
industries with generous advertising budgets persuade many people that it
is better to have expensive urine than be at risk to disease
through lacking the right vitamin or mineral in a diet.
