Why organic food is better? Ten Reasons

By Guy Dauncey

1. Organic farming is better for wildlife

A report by Britain’s Soil Association shows that wildlife is

substantially richer and more varied on organic than on

conventional farms. A typical organic field has five times as many

wild plants, 57% more species, and 44%

more birds in cultivated areas than a

regular farm

that organic farms have twice as many

skylarks, and twice as many butterflies

Every time we eat an organic lettuce or

tomato, we help restore wildlife.

1. Two 1996 studies show2.

2. Organic farming is better for

the soil

Studies show that organic fields have

deeper vegetation, more weed cover, and

contain 88% more ‘epigeal arthropods’

(squiggly soil creatures)

study demonstrates that organic soils

have more soil microbes, more

mycorrhizae – the fungi that attach

themselves to the tips of plant roots and

help plants absorb nutrients - and more

earthworms

are twice as abundant and more diverse

in organic plots, including pest-eating

spiders and beetles.

Organic food is better for animal reproduction

Out of 14 animal studies, ten showed that animals fare better when

fed organic food. Three showed no difference, and one showed an

improvement with conventional food. We are all mammals, so we

share a lot in common. Female rabbits fed on organic food have

twice the level of ovum production; chickens fed on organic food

have a 28% higher rate of egg production. Rabbits that were fed

conventional food saw a decline in fertility over three

generations, compared to no decline for organically fed rabbits

Meanwhile, many human couples find it hard to have a baby….

4. Organic food helps fight cancer, stroke and heart

problems

In a recent study, Scottish scientists found that organic vegetable

soups contain almost six times as much salicylic acid as nonorganic

vegetable soups. Eleven brands of organic soup had 117

nanograms per gram, versus just 20 nanograms in 24 types of

non-organic soup

aspirin; it helps fight hardening of the arteries and bowel cancer,

and is produced naturally in plants as a defence against stress and

disease. If plants don’t have to resist bugs because of pesticideuse,

they generate less salicylic acid, and pass less on to us. The

same scientists found significantly higher concentrations of

salicylic acid in the blood of vegetarian Buddhist monks,

compared with meat-eaters.

6. Salicylic acid is the main ingredient in

5. Organic food contains more nutrients

According to a recent study by the Globe and Mail and CTV News

of the nutrient quality of fruit and vegetables, compared to 50

years ago, today’s regular fruit and vegetables contain

dramatically less vitamins and minerals

lost 100% of its vitamin A, 57% of its vitamin C and iron, 28% of

its calcium, 50% of its riboflavin, and 18% of its thiamin. Out of

seven key nutrients studied, only niacin levels increased. Similar

results applied to 24 other fruits and

vegetables. For broccoli, all seven nutrients

fell, including a 63% decrease in calcium and

a 34% decrease in iron. No wonder we are

gulping down the supplements.

In April 2001, however, a US study examined

41 comparisons of the nutrient levels in

organic and regular foods. In every case, the

organic crops had higher nutrient levels -

27% more vitamin C, 29% more iron, 14%

more phosphorus

of the American Chemical Society, a

chemistry professor reported that organic

oranges contained up to 30% more vitamin C

than regular oranges, even though they are

half the size

fed nitrogen fertilizer, causing the fruit to

absorb more water, which makes them

bigger.) In a French study, a cancer specialist

studying the nutrient qualities of food grown

in the Languedoc-Roussillon region of

France showed that for the twelve foods

where his study is complete, the organic

foods showed increased quantities of vitamins A, C, E, and the B

group, increased elements such as zinc, increased minerals such as

calcium, and increased fibre

6. Organic apples are …. just better!

From 1994 to 1999, a soil scientist at Washington State

University ran a series of tests comparing apple orchards. The

organic orchard had the best soil, held water better, and resisted

soil damage better. It was more energy efficient, and required less

labour and less water per apple. The organic apples were firmer,

tasted sweeter and were less tart to a non-expert panel. The organic

orchard also made more money, since the apples sold for a higher

price

7. Organic farming can feed the world

In a 2002 Greenpeace report, the authors found that organic and

agro-ecological methods of growing in the Southern hemisphere

produced a dramatic increase in yields, as well as reduced pests

and diseases, greater crop diversity, and improved nutritional

content. In the Tigray, Ethiopia, organic crops raised 3-5 times

more food than chemically treated plots; in Brazil, maize yields

increased by 20 – 250%; in Peru, uplands crop yields increased

by 150%

In 1998, the Rodale Institute in Kutztown, Pennsylvania,

published the results of a 15-year study that compared 3 ways of

growing maize and soybeans – a conventional chemical rotation

method, an organic system involving crop rotation and legume

crops, and an organic system using cow

manure. The yields were similar for all three

systems, debunking the myth that organic

methods cannot feed the world

an experiment run at Broadbalk by the

Rothamsted Experimental Station for 150

years has shown that wheat yields on

manured plots average 3.45 tonnes per

hectare, compared to 3.40 tonnes on the

chemically fertilized plots

A recently completed 21-year Swiss study,

on the other hand, showed that organic

yields were 20% smaller than conventional

yields. The organic plots required 34% to

53% less fertilizer and energy and 97% less

pesticide, however, and produced more food per unit of energy

and fertilizer. The soil microbes, flora, fauna and soil fertility also

increased, leading the study’s authors to conclude that the ecological

benefits of organic farming make up for the reduced

harvest

8. Organic farming protects the climate

Organic soil is full of living creatures, which carry carbon. In the

Rodale experiment, the organically managed plot stored much

more carbon than the conventional plot. In the Broadbalk

experiment, soil fertility increased by 120% in the manured plots,

versus 20% in the chemical plots. The same results occurred in the

Swiss experiment. A study in California’s Central Valley showed

that as well as producing similar yields and suffering similar pest

damage, organically managed fields produced 28% more organic

carbon. By storing more carbon in the soil, organic farmers help

to stop global climate change.

9. Organic farming produces higher yields in drought

conditions

In a review of comparative studies of grain and soybean

production in the US Midwest, organic growers produced higher

yields in drier climates and during droughts (and similar yields

in regular conditions)

Rodale experiment. Organic matter makes the soil less compact

and more moisture retentive, allowing the roots to penetrate more

deeply to find water.

16. The same results were found in the

10. Organic food is safer

Organic farming generates more jobs, produces more profits, and

doesn’t pollute groundwater with nitrogen run-off. It also avoids

all the risks associated with GM crops. But let’s finish with the

reason why many people start eating organic food – because they

believe it is safer. Farmers in Canada, Kansas and Nebraska who

use the pesticide 2,4-D suffer a higher rate of non-Hodgkin’s

lymphoma (a cancer). The same applies to dogs which play on

lawns that have been sprayed. In Sweden, exposure to phenoxy

herbicides has been shown to increase the risk of contracting

lymphomas six-fold

cancer) are highest in rural farming areas

Migrant farmworkers suffer an abnormally high rate of multiple

myeloma, stomach, prostate and testicular cancer

farming carries none of these risks.

There is a strong association between breast cancer and exposure

to chemical pesticides. Atrazine, a common ingredient in

pesticides, causes breast cancer in rats, chromosomal breakdown

in the ovaries of hamsters

Finnish study showed that women whose breasts stored the

highest levels of a lindane-like residue were ten times more likely

to have breast cancer than women with lower levels

a pesticide).

We can end all this by shifting to organic food. We can be

healthier. Our children can be healthier. Our farmers and farm

workers can be healthier. Frogs, worms, butterflies, skylarks and

the soil itself can be healthier. All that it takes is to turn away

from chemically grown food, and embrace

organic food.
