The
facts about organic foods; having more vitamins and minerals protects
you from chronic disease
Here's
an outstanding overview of the facts about organic foods and how
they improve your health standing. Highly recommended reading.
The bottom line? Organic foods contain more vitamins and minerals,
no pesticides, fewer additives, and much lower levels of toxic
chemicals. As a result, they have tremendous potential for preventing
chronic diseases like cancer, diabetes, heart disease and many
others.
As
a bonus, when you purchase organic foods, you support organic,
sustainable farming practices that are good for the environment,
too.
Overview:
This
factsheet is a summary of an article published in "Coronary
and Diabetic Care in the UK 2004" by the Association of Primary
Care Groups and Trusts (UK).
It was written by James Cleeton, Policy Projects Co-ordinator
at the Soil Association.
· appears to have the potential to lower the incidence
of common conditions such as cancer, coronary heart disease, allergies
and hyperactivity in children.
The routine use of synthetic pesticides is not allowed under organic
standards.
Currently, over 400 chemicals can be regularly used in conventional
farming to kill weeds, insects and other pests that attack crops.
For example, Cox's apples can be sprayed up to 16 times with 36
different pesticides.
7 Only four chemicals are allowed in restricted circumstances
under Soil Association standards.
"Organic food contains fewer residues of pesticides used
in conventional agriculture, so buying organic is one way to reduce
the chances that your food contains these pesticides" (Sir
John Krebs, Chair, Food Standards Agency, Cheltenham Science Festival
debate, 5th June 2003).
"Consumers who wish to minimise their dietary pesticide exposure
can do so with confidence by buying organically grown food"
(Baker et al 2002).
The most dangerous chemicals used in farming such as organophosphates
[pesticides] have been linked with a range of conditions such
as cancer, decreasing male fertility, foetal abnormalities, chronic
fatigue syndrome in children and Parkinson's disease.
8,9 Pesticide residues have been ranked among the top three environmental
cancer risks by the American Government.
In recent years, UK Government research has consistently found
pesticide residues in a third of food, including residues of more
than one chemical in apples, baby food, bread, cereal bars, fresh
salmon, lemons, lettuces, peaches, nectarines, potatoes and strawberries.
11 Not all foodstuffs are checked; instead a small number of different
products is tested every 3 months and the results published by
the Pesticide Safety Directorate (PSD).
After pressure from NGOs [non-governmental organisations] such
as the Soil Association, the PSD has begun testing for multiple
pesticide residues in its samples because evidence suggests that
when acting in combination, harmful effects of pesticide residues
may be increased.
Combinations of low-level insecticides, herbicides and nitrates
have been shown to be toxic at levels that individual chemicals
are not.13 - 16 It is clearly an enormous task to test all possible
combinations of the 400 permitted pesticides currently in use.
Women with breast cancer are five to nine times more likely to
have pesticide residues in their blood than those who do not.18
Previous studies have shown that those with occupational exposure
to pesticides have higher rates of cancer.19 - 21 The apparent
link between hormone dependent cancers, such as those of the breast
and prostate, may be via endocrine disrupting chemicals [compounds
that artificially affect the hormone system] such as 2,4D and
Atrazine (both herbicides, now banned or about to be banned).
In a study of children aged 2 --4 living in Seattle, concentrations
of pesticide residues up to six times higher were found in children
eating conventionally farmed fruit and vegetables compared with
those eating organic food.23 Whilst the presence of pesticide
residues in children eating conventional food has been confirmed,
the full effect of such pesticides are unknown.
Food colourings and additives can cause a range of health problems
in adults and children.
Although around 300 additives are permitted in conventional food
only 30 are allowed under Soil Association standards.
Some additives found in organic food are added for legal reasons
including iron, thiamine (vitamin B) and nicotinic acid (vitamin
B3) in white flour, and various vitamins and minerals in different
types of baby foods.
All artificial colourings and artificial sweeteners are banned
in organic food.
Specific ingredients and additives not allowed in organic food
are monosodium glutamate, aspartame, phosphoric acid and hydrogenated
fats.
In each case their use has been banned because of evidence that
they can be damaging to health.
For example, hydrogenated fats (also known as trans fats) have
been directly linked with increased rates of heart disease, cancer
and skin disease.
28,29,30,31 The FSA [Food Standards Agency] acknowledges that
they have no known nutritional benefits and increase the risk
of coronary heart disease.
The FSA website advises that people should try to cut down their
consumption of hydrogenated fat.
Genetically modified organisms are banned from organic food.
The potential health effects of GM foods are unknown.
Michael Meacher the former Minister for the Environment recently
stated that "We have had no systematic clinical or biochemical
trials of the effects on human beings of eating GM food".
A paper in Nutrition and Health 33 supports Mr Meacher's position.
The authors state that there have only been ten published studies
of the health effects of GM food and that the quality of some
of these was inadequate.
Over half were done in collaboration with companies (fully or
partially), and these found no negative effects on body organs.
The others were done independently and looked more closely at
the effects on the gut lining; in several, evidence of harmful
effects were found which remain unexplained.
Similar effects on the gut lining were found in an unpublished
animal feeding study on a GM tomato.
In addition, a study by Newcastle University sponsored by the
FSA found that the transgenes [genetically modified organisms]
transfer into gut bacteria at detectable levels after only one
GM meal.
The health effects of these transgenes are unknown and until they
have been properly tested people are, in our opinion, wise to
avoid eating GM food.
UK and US government statistics indicate that levels of trace
minerals in fruit and vegetables fell by up to 76% between 1940
and 1991.
34,35 In contrast there is growing evidence that organic fruit
and vegetables generally contain more nutrients than non-organic
food.
The Soil Association conducted a systematic review of the evidence
comparing the vitamin and mineral content of organic and conventionally
grown food.
It was found that, on average, organic food contains higher levels
of vitamin C and essential minerals such as calcium, magnesium,
iron and chromium.
An independent review of the evidence found that organic crops
had significantly higher levels of all 21 nutrients analysed compared
with conventional produce including vitamin C (27% more), magnesium
(29% more), iron (21% more) and phosphorous (14% more).
Organic spinach, lettuce, cabbage and potatoes showed particularly
high levels of minerals.
A high antioxidant intake has been shown to be associated with
a reduced incidence of coronary heart disease and some cancers.
Forage based diets [a diet based on fresh or dried food as opposed
to processed feed] form the basis of organic livestock production
systems and have the potential to decrease saturated fat concentrations
and to increase the concentrations of omega-3 57, 58 and CLA 59,50,61
in beef.
Sperm concentrations have declined and abnormalities in sperm
development have been recorded.
